#WildEssexWalks: an evening potter around Wivenhoe Barrier Marsh

It was third time lucky for our evening walk around Barrier Marsh and Wivenhoe Waterfront, postponed once because of extreme heat and once more through illness. Our third attempt with an eager throng of friends was still warm, around 24°C at 7pm when we set off, but a delicious, gently cooling easterly breeze made conditions very pleasant.

Starting at the Shipyard, our block-paving population of Four-leaved Allseed seems to be having an outstandingly successful year, seemingly impervious to extreme drought and chemical onslaught. First found here during the pandemic, its distribution is still expanding from its original haunts of south Cornwall and the Scilly Isles.

The saltmarshes have no showy flowers at the moment, at least until the Sea Aster comes out later this month, although Common Cord-grass is in flower along with Sea Purslane. The super-salty hit of the leaves of the latter, covered in the excretions from its desalination cells were a surprise to many. And Marsh Samphire was, as is typical of some forms at this stage of the season, shot through with succulent emerald.

The Sailing Club hedge was starting to look very autumnal, with sloes, hips and haws all filling nicely, surprisingly perhaps given that it has not rained a drop here for more than a month. These will of course become vital winter bird food, assuming the hedge is not attacked by the ‘tidy brigade’…

As usual, Strawberry Clover was looking magnificent along the extreme high tide line, and an interesting new feature, a microcosm of Orford Ness, has recently been installed:

Below the Barrier, the estuary widens and the local moulting Black-headed Gulls were joined by the first returning Curlews, plus Oystercatchers and Redshanks, some at least of which may be local breeders.

The seaward face of the sea wall was in places clothed with the grey, absinthe-scented leaves of Sea Wormwood, although it has yet to come into flower.

Crossing the grazing marshes on The Chase, it was, as everywhere, very parched, especially so on the tops of the numerous anthills illuminated beautifully by the slanting, setting sun.

Few flowers were showing apart from occasional Hairy Buttercups and patches of Creeping Thistles, on one of which Jude (of course!) spotted a beetle Anthocomus rufus, sometimes known as the Red Malachite-beetle, a species closely associated with coastal habitats. Although it appeared to be feeding in the flowers, it is primarily a predator of other insects, and so may have been searching rather than supping. And with the aid of our bat detector she also picked up the song of a Dark Bush-cricket. But nobody could hear it unaided…. we are all of a certain age!

Birds were few and far-between, just a calling Green Woodpecker and skulking Whitethroats and Reed Warblers in scrub and reedbeds respectively. That is until sunset, when the birds woke up, with Robin and Cetti’s Warbler singing and groups of Little Egrets heading down river presumably to a communal roost.

All that remained was to potter back along the Wivenhoe Waterfront in the glorious gloaming, buy a welcome cooling pint at the Rose & Crown, and settle down outside to watch and hear the first hunting Common Pipistrelle, as well as a remarkable chorus of House Crickets. From the bottom of Anchor Hill to Bethany Street, there were multiple singing males, many more than we heard last year, the first time we recorded them here. Instant transportation to the southern climes of Europe, and a thrilling, trilling end to a lovely walk!

#WildEssexWalks: Lower Lodge in the grip of a heatwave

As is by now traditional, we organised a WildEssex walk in high summer around Lower Lodge nature reserve, near Wivenhoe. Lower Lodge is a lovely, flower -rich grassland site, mostly mown on a three- or four-year rotation by Colchester City Council, producing a diversity of habitat structure, from woodland, to dense scrub, to scattered scrub to open grassland. All components have their value, although the open grassland is especially diverse for both insects and flowers.

But we hadn’t planned on a summer like the current one. An unprecedentedly hot, dry summer with three heatwaves and droughts already, and it is only mid-July. So it was with some trepidation we set out onto the site to see what we could find. At least there were plenty of pollen- and nectar-bearing flowers, particularly Wild Carrot, Hogweed, Common Knapweed, Field Scabious, Creeping Thistle and the beautiful bicolored form of Field Bindweed.

From a distance there were a few butterflies flitting around, but I was stopped in my tracks at the very first Carrot umbel: Ectophasia crassipennis! A stunning parasite-fly that lays its eggs on unfortunate shield bugs before the fly larvae devour the bug from the inside. Slowly….

It is a species I know well from the Pyrenees that first reached the UK in 2019; it is now found widely along the south coast, but is only just starting to head our way. So far as I can ascertain there are only a couple of other records from Essex, one at Wrabness in the year of its first arrival and one last year that I found in Beth Chatto Gardens.

We then carried on on the parasite-fly theme, recording two more species, Tachina fera and Eriothrix rufomaculata.

What a great start and although individual numbers of most insect species were not high we kept on finding things of interest until the end of the two hours when the other absolute highlight performed as the very last insect of the walk. This was a Hummingbird Hawkmoth, always good to see and reasonably common this summer. But what was it doing hovering its way through, not over, the grass, avoiding the flowers, completely oblivious to us as it flew between us, and occasionally touching down? And then it twigged, ‘it’ was a ‘she’, she was laying eggs on the Hedge Bedstraw plants growing in the grassy sward. This is not a behaviour I have ever seen before, so our walk ended with me as excited as when we started!

Sadly, unless any larvae develop very quickly such that the next generation is out by early autumn, they are unlikely to survive our winter. But maybe, just maybe, a warm winter could allow it to succeed.

Other moths we saw during the walk were many and varied, from grass moths like Agriphila straminella (all very brown and flittery) to the stunning Brassy Longhorn (a specialist moth dependent upon Field Scabious, seemingly very scarce in Essex) and of course the Six-spot Burnets, resplendent in their black and red livery in the sun, whirring around, occasionally landing to feed, and some new emergers just drying out close to their vacated pupal cases.

Other flies feeding on the umbels included the hoverfly Chrysogaster solstitialis and lots of Flesh-flies, while sitting around on the leaves, either mating or on the lookout for insect prey were Kite-tailed Robberflies, alongside tiny sweat-bees Lasioglossum sp.

Another selection of insects feeding on flowers comprises a parasitic ichneumon wasp (the nemesis of caterpillars), Turnip Sawfly, a Knapweed Bug Oncotylus viridiflavus (for which there are only a couple of records east of Colchester), Hairy Shieldbug, Seven-spotted Ladybird, Thick-thighed Beetle and Hogweed Bonking-beetle. A veritable cornucopia of delights!

So among the insects that leaves just the butterflies. Gatekeepers were the most numerous, with just a few Meadow Browns, good numbers of pristine Painted Ladies, and a very few Small Skipper and Common Blues.

In addition, but not photographed, were Small and Green-veined Whites, single Red Admiral, Brown Argus, Small Heath and a Purple Hairstreak that had a lucky escape from a spider’s web up in an oak canopy.  And flying around the fields there were Emperor, Brown Hawker and Common Darter dragonflies, and Willow Emerald and Common Blue Damselflies.

Aside from insects, there was plenty more of interest, including a spider Enoplognatha with its hoverfly prey, abundant Oak Mildew, artichoke and marble galls on Oaks, and a good fruiting of sloes.

And just to finish off, the things we didn’t see as a group, but which I found on my recce a couple of days previously: leaf mines on oak and galls on Wild Rose (we just didn’t have time to hunt them all out on the walk)…

… Box Bug and Cinnabar caterpillars

… Ringlet and Small Copper

… and a hoverfly Xanthogramma pedissequum, known aptly as the Superb Dayglower.

Yes, Lower Lodge performed very well as always, a powerhouse of biodiversity on our doorstep!

The Colne Valley, from Chappel to Chalkney Wood, and back…

The mid-reaches of the River Colne, around Chappel, constitute a lovely, quintessentially Essex, mixed agricultural landscape, with extensive pasturelands in the valley bottom, either side of the clear, flowing river; arable on the high ground, parcelled up between hedgerows; and woodland, much of it ancient, on the valley slopes, embracing the spring-lines. An ideal place for long walks, not expecting to see anything rare, just Spring in all her glory, so last week I did that twice, first a full day with Naturetrek and two days later, a half day with #WildEssex.

The first walk started rainy, the first rain for a month, but soon gave way to sunshine, although a stiff northeast breeze kept the temperature down. Two days later, wall to wall deep blue skies, and lighter winds from a warmer, more southerly direction. The blue backcloth was ideal to appreciate the rainbow of greens, each tree providing its own interpretation before high summer dust dulls the difference.

Starting from Chappel, wheezing Greenfinches, twittering Swallows and willows heavily infested with Mistletoe kicked the walks off, along with a fascinating cluster of historic buildings reflecting the diversity of bricks made in the local brickworks. The churchyard wall in particular features the old bricks, and supports a wealth of mosses and lichens, crevice plants like Ivy-leaved Toadflax, and ones such as Red Valerian and Greater Celandine using the wall as a storage heater to mimic their Mediterranean mountain homes.

Heading upriver, the Colne flows between shaded banks, clad in Nettles, pinpricked white with Garlic Mustard: too early for the fluttering sprites, the Banded Demoiselles of summer, the waters were already providing flying life, in the form of Alderflies and mayflies.

The open pastureland of the valley bottom is not especially diverse botanically, although there was Meadow Foxtail in the drier areas, Lesser Pond-sedge and Cuckooflower where damper, and a triumvirate of buttercups – Meadow, Bulbous and Creeping.

Hedgerows of Hawthorn in full fragrant bloom and Blackthorn, most well over but some bizarrely still in tight bud, provided shelter for patrolling Orange Tips and Green-veined Whites, and the last, tatty overwintering Commas alongside the first, scintillating blue Holly Blues, while Whitethroats, both Common and Lesser, sang from within, and Ash leaves and Field Maple flowers introduced their vivid yellow-green colour to the surroundings.

Buzzards, maybe three pairs, soared and displayed overhead, joined by a lone Red Kite, as a Mistle Thrush proclaimed territory atop the largest Oak.

Cowpats! And happily, cowpats with insect holes, suggesting these cattle have not been treated with ivermectins which kill the rich diversity of dung. And sure enough two days later, a lot warmer, and the Yellow Dung-flies were out in force, feeding and frolicking.

Back into more sheltered areas. Evergreen Alkanet amongst the Stinging Nettles provided boundless opportunities for Dark-edged Beeflies and ladybirds, mostly 7-spot but with Cream-spot and 14-spot as well. Several St Mark’s Flies rested alongside the first Red-headed Cardinal Beetles of the year, all under the watchful gaze of basking Nursery-web Spiders.

A sunny wall and wooden fence, providing security for an isolated mansion off the beaten track, was teeming with Zebra Jumping-spiders, one of whom had caught a meal in the form of a Pond Olive mayfly (not that I realised it until I looked at my photos back at home!). And in another bit of post-hoc reassessment, a harvestman on that fence would appear to be Platybunus pinetorum. First found in Britain as recently as 2010 and known mostly from more northern areas, this will be (if confirmed) the first record from Essex, and quite possibly East Anglia.

Close to the river, there were three species of damselfly: several Large Reds, always the first to emerge in the spring, with single female Azure and Blue-tailed, the latter so fresh it was practically colourless, a so-called teneral specimen.

The final upstream section took us past fields of magnificent Longhorn cattle to one of the many former mills on the river, where Grey and Pied Wagtails fed, House Martins chirruped and swooped, a Kingfisher was heard, and a Little Egret bore witness to the inexorable march of climate collapse…

Thence into Chalkney Wood, a place I have been coming to for forty years. An inspiration! A Renaissance wood! A phoenix rising from the ashes of destructive early 20th century forestry policy: when I first knew it, Chalkney’s ancient woodland roots were buried under serried ranks of non-native conifer trees. Fortunately we recognised that those who attempted to destroy the old trees a generation previously had not been very efficient; green shoots of hope remained. And when in 1987 the plight of ancient woods was highlighted by the ‘hurricane’ that swept through our lands in October, it didn’t take too much of a push to guide the Forestry Commission down the path towards a sustainable future.

The conifers were removed ahead of their intended lifespan, light flooded back, life responded accordingly, and now thirty years later it is almost impossible to differentiate that part of the wood from the smaller portion that Essex County Council had presciently been able to rescue from the jaws of doom years before…

Over vast swathes of the wood, Bluebells were only just past their best, a colour scheme interrupted only on some damper patches where white Wild Garlic dominated. And both smelled as good as they looked.

 

Other flowers included cushions of Greater Stitchwort and Ground Ivy, especially around the wood edge, and Bugle and Wood Speedwell lining the rides:

The dominant coppice trees are Hornbeam and Small-leaved Lime, the latter particularly beautiful as its pink-flushed buds open, and Hollies (of both sexes) flowered on the woodbanks. Blackcaps and Chiffchaffs sang everywhere, with a lovely Garden Warbler both days around the lunch stop.

The sunny rides were also the place to find insects, including Speckled Wood, Orange Footman moth, Birch Shieldbug, the hoverfly Pipiza noctiluca, and two ‘longhorns’, Green Longhorn Moth and the beetle Rhagium mordax, rather scattered in Essex, being restricted to ancient woodland habitats.

The return journey was along the hill tops (yes, Essex does have hills!) giving wonderful views over the unspoilt valley. Long may it remain that way. Dandelions as always attracted insects, here a Gooden’s Nomad-bee, and sheltered nettlebeds harboured Hairy Shield-bugs and a Cinnamon Bug. And stunted hedgerow Oaks showed the large, spongy oak-apple galls of the wasp Biorhiza pallida.

The eroded path gave a window into local geology, flint-rich chalky boulder clay deposited by the last outpost of the Anglian Glaciation, before at least the Naturetrek group plunged through a waist-high Rape field. It was surprising just how many insects there were in the monoculture, from Small Whites to Honeybees and several others. We can only hope the Rape was not bearing a lethal dose of neonicotinoid pesticides…

And finally everyone got to pay homage to Chappel Viaduct, up close and personal, at its very best in slanting sunlight, a graphic masterpiece of Victorian architecture, as sound now as when it was built 160 years ago. Worth the effort of visiting in itself, especially for those travelling by train and seeing views both of and from. All rounded off for some with a welcome drink at The Swan: the wild side of Essex at its best!

#WildEssex: A Glorious Spring Walk to Cockaynes Reserve

We have often led a walk up to the Cockaynes Reserve searching for Spring, but never have we had such wonderful weather for it as yesterday. And it was only 3rd of March! Azure skies, light winds and warm sunshine were just what we needed after the grim, grey gloom of February.

And it seems nature needed it too as it was out in abundance. As we walked up Ballast Quay Lane, starting with the customary chirrups of the gaggle of House Sparrows, the air was alive with Greenfinches singing/wheezing and Great Tits getting frisky, while the verges were blooming with Sweet Violets and Lesser Celandines.

And everywhere a rainbow of greens, from the dusty, dull, dark Ivy green to the vibrant emerald of fresh Hawthorn leaves and moss spore-capsules.

As we crossed the open fields, enjoying some of the best views of this part of the world from the top of the Essex Alps, Skylarks filled the air with exuberance as Rooks probed for grubs, and in the distance a couple of Egyptian Geese grazed. Red Dead-nettle, Common Field Speedwell and Bulbous Buttercup flowers were shining among the twinkling Daisies and Dandelions.

Turning into Villa Wood alongside Sixpenny Brook, we entered a moss-clad world, the haunt of our Scarlet Elf-cups, the reason this reserve exists. Perhaps not so many as last year’s bumper haul, but they were there, mantled in mossy green,  and maybe still more to come.

Spring is a time of rapid change but also delayed gratification: the spearing shoots of Bluebells will be transforming this woodland floor in six weeks or so:

Sibilant twitterings in the Alder tops revealed a party of at least 20 Siskins, and the first of half-a-dozen Chiffchaffs sang, surely new arrivals on the recent deep southerlies laden with Sahara dust.

Hazel flowers, always the pre-Christmas first sign of the Spring to come, going over, and the Big Bud galls starting to form; Alder catkins peaking with Silver Birch still to come;  Sallow pompoms just bursting, attracting numerous bees; and Cherry-plum in full flower with Blackthorn bud-burst perhaps a couple of weeks away: Nature’s Calendar in full flow!

Onto the heath, the glorious Gorse flowers hid the glistening nuggets of Gorse Shield-bugs, so well camouflaged among the emerging buds. Queen bumblebees bumbled through the flowers, and there were Seven-spot Ladybirds everywhere. Much more numerous than I have ever seen before at this time of year, these are presumably the offspring from last July’s mega-influx.

Basking on a fencepost nearby was what may be an early Gorse Mining-bee, along with a pugnacious Zebra Jumping-spider, ready to take us all on! The bee bank was teeming with Bunny Bees, one of the key features of this reserve, and especially pleasing as only a day previously, on my recce in similar sunshine, I had seen just a couple.

Two lots of Buzzards were overhead, mewling in display flight and carrying nesting material, while a female Marsh Harrier quartered the reedy willow scrub.

Several pairs of Long-tailed Tits seemed to be setting up territory and there were fleeting flypasts of both Peacock and Red Admiral, though no sign of yesterday’s Comma, my first butterfly of the year. Nor were there any of the Hairy Shield-bugs on show: such is the excitement and unpredictability of the natural world. But the final reward for we two leaders was back in town, just after the last of our group peeled away, the most vibrant male Brimstone crossing our path …

 

#WildEssex New Year Plant Hunt 2026

Each year, the Botanical Society of Britain & Ireland organises a New Year Plant Hunt, encouraging botanists and other interested folk out of their midwinter slumber to see what plants are flowering. And traditionally this has been our first #WildEssex event of the year, a walk around Wivenhoe Waterfront on New Year’s Day, except as in 2025 when forecast bad weather dictated otherwise.

All data collected in this citizen science project are fed into the national record of what is flowering at this time: for more information see New Year Plant Hunt 2026. It is important to be part of a bigger project to aid learning about how British and Irish wildflowers are responding to climate change.

New Year’s Day 2026 was certainly more clement than 2025, sunny although pretty cold, barely above freezing, or should we say ‘normally cold’ by the norms we grew up with… Our band of 15 friends accompanied Jude and I and our special helper, scribe, photographer and flowerfinder Eleanor as we wandered round the usual route in the standard hour. It produced a good number of the ‘usual suspects’, shrubs that routinely flower in the depths of winter such as Gorse (apart from the usual Hazel that had been cut back severely) and annuals that flower at any time of year if the previous few weeks have been mild (as they were last autumn), including Annual Mercury, Petty Spurge, Shepherd’s-purse and Annual Meadow-grass.

The few areas of permanent grass on our route had Daisies and Dandelions sparkling sparsely on them, together with Common Knapweed and Oxeye Daisy as a distant memory of the summer long gone, and Sweet Violet, the promise of spring. Along the fringes of the recreation area, Hedgerow Crane’s-bill was a new species for our NYPH list, as was Cut-leaved Dead-nettle, never very common in these parts, and growing alongside its more familiar relative, Red Dead-nettle, with more shallowly divided leaves and larger, darker flowers.

In the heart of the village, the older walls and brickwork supported Mexican Fleabane, Trailing Bellflower, Pellitory-of-the-wall and Ivy-leaved Toadflax, while it was quite a surprise to find Ivy flowers still open in places.

Along the waterfront itself, in the cracks of the block paving, our two specialists of this habitat, Four-leaved Allseed and Jersey Cudweed were both found just in flower along with the undoubted star of today’s show, White Ramping-fumitory. Rather scarce nationally, but  widespread around coastal north Essex, it was in exuberant flower in planters and cracks along the waterfront, untroubled by any frosts so far this winter.

And at the end of the hour we found ourselves at the saltmarsh, where Common Cord-grass with its naughty bits glistening in the sinking sunlight added a final species to our tally:

All in all, 39 species in flower represents a new high for us (see full list here New Year Day PLANT HUNT Year on year) compared with 37 in 2025, 34 in 2024, 23 in 2023, 35 in 2022 and 30 in 2021, although one should fall short of celebrating – many of these plants should not be flowering now, and are doing so only because of the harm we have inflicted upon our climate…

There is of course another way of looking at it. Plants are not the only things responding to climate change: although we saw no insects being active on the day of our walk, it is undeniable that fewer insects are hibernating than used to be the case. And year-round activity needs year-round nectar and pollen resources, so any insect-attracting flowers such as Gorse and dead-nettles are important, even in the context of much richer supplies inside our gardens, as for example the gorgeous, subtly showy blooms of Virgin’s-bower Clematis cirrhosa. Happy New Year!!

These NYPH events are always free to participants, being as much as anything a chance to reconvene with old friends, both botanical and human, after the midwinter lull and start to look forward to the riches of the summer that is surely to come. But this year we did suggest that satisfied customers may like to contribute to the crowd funder to seek justice for the much-loved community oak tree in Wivenhoe, Old King George.

This tree has dominated our lives for the whole of 2025. The first part was covered in my blog of February: Saving Wivenhoe’s Old King George Oak Tree | Chris Gibson Wildlife. In essence, the tree is caught up in the grip of the insurer Aviva and Wivenhoe Town Council. Blaming it for subsidence, a death sentence was issued. This was fended off last winter by peaceful occupation by the Protectors, but the sentence was reaffirmed last month. And still now, as previously, all evidence pertaining to its guilt has been withheld from the public gaze. Despite the fact that the Protectors and their supporters funded and produced an (openly available) independent expert report which challenged the presumption of guilt. And another independent report with similar conclusions to ours was prevented from consideration by the council.

So we have had to take recourse in law. All we are asking for is full transparency: if the guilty verdict is supported by indisputable evidence, we would reluctantly accept it. A few days ago our legal team successfully won an injunction in the High Court to pause its felling which had been planned for early this year. A pause for democracy to be seen to be done.

Of course, this is expensive, hence the launch of our new CrowdJustice funder. Please consider contributing if you can using this link: Save Wivenhoe’s Old King George Oak tree

 

#WildEssexWalks: fungi, fruits and foliage in Wivenhoe Park

Our first #WildEssex walk after an enforced break of more than four months took us up to Wivenhoe Park with a large bunch of friends. This is a semi-regular autumnal walk venue for us, hoping to find fungi, fruits and foliage colours to usher us into winter.

Best laid plans! So much of what we hoped for is dependent upon preceding weather conditions, the sort of thing that is becoming less predictable as we continue in our arrogance to push our world inexorably beyond the agreed +1.5°C safe threshold.

It is always good when nature contradicts our assumptions. A hot, droughty summer followed by autumn rains and no sign yet of frost, I would have thought, seems a perfect recipe for a spectacular emergence of fungi. But it was not to be: even the ‘little brown jobs’ were few and far-between, and larger fungi even more so. There were Common Earthballs, some intact and others rupturing to liberate spores, together with a patch of Honey Fungus, and  Aniseed Funnel  and Deer Shield. But nothing compared with the rich array of some years.

Bracket fungi are usually more reliable, so it was not a surprise to see Birch Brackets, the nemesis of many a Birch tree, and Beefsteak Fungus, the latter growing from the buried roots of a veteran Oak.

But the most common fungus, covering the leaves of almost every sapling Oak was Oak Mildew. This at least seems to have found this summer’s weather to its liking.

For most trees and shrubs, the summer has produced copious fruiting, a so-called ‘mast year’, except bizarrely for Beech, the tree whose seeds are called ‘mast’.

Not that copious fruiting is necessarily a good sign. It way well be a response to stress, for example caused by the past three-drought summer. Although of course those things that eat the fruits are in for a bonanza: winter thrushes arriving in this country will be very happy to find an abundance of berries, here on Hawthorn and Cockspur Thorn.

On Yew as well, although strictly speaking those are not berries as the flesh doesn’t entirely envelop the (very poisonous) seed. Botanically, the Yew ‘berry’ is termed an aril.

Foliage colour is of course the epitome of autumn. But it is variable between years, again dependent on preceding weather. We had been hoping after the heat of summer for an autumn palette of shocking reds, but again ’twas not to be. The lack of any frost yet means that native trees are mostly turning yellow: here English Oak, Hornbeam, Field Maple, Beech and Aspen.

And even planted trees are not firing up as much as they can: Red Oak has just gone brown, although Tulip-tree has a bit more body to it, and Dawn Redwood is the most subtle peach just before the needles fall.

As always at this time of year, galls were numerous. On the leaves of Beech, there was the Hairy Beech Gall caused by the fly Hartigiola annulipes, a gall recorded from only about half a dozen other sites in Essex.

Some of the leaves also bore the signs of leaf-miners. This is the larval mine of Stigmella tityrella, a micromoth: the larva has exuded a chemical that delayed the senescence of its part of the leaf, giving time in the ‘green island’ to complete development.

Galls are caused by many different types of organism. The lumpy upward pouches on the delightfully scented leaves of Walnut are caused by and make a home for vast numbers of microscopic mites, Aceria erinea.

Very familiar under the leaves of English Oak are Common Spangle Galls, caused by the tiny gall-wasp Neuroterus quercusbaccarum. But other oaks are available. And there were similar galls under the giant leaves of the Far Eastern Daimyo Oak Quercus dentata. Similar but not quite the same, being more blobby and rounded rather than a flattened disc. Perhaps this is the shape of galls caused by the interaction with a relatively novel host plant: certainly this is the opinion of Essex Gall Recorder Jerry Bowdrey, who informs us it was first recorded on this host in a survey of Kew Gardens at the end of the 19th century, and that he  has also found it more recently at Marks Hall.

Also living on Daimyo Oak leaves was a Green Shieldbug , while a Hairy Shieldbug was also found.

A Red Admiral was spotted by some of the group, and one of the day’s highlights was expertly spotted by Jude, a Feathered Thorn moth wonderfully camouflaged against a brown Red Oak leaf. Autumnal moths are often shades of brown, yellow or russet for camouflage. But this one has additional darker lines that match the veins of the dying leaf.

It was a lovely walk in lovely weather: it is good to be back!

#WildEssexWalks: Harwich and Landguard Point

Phew! That was a hot one: midsummer, crystal blue skies, fierce sunlight, tempered only by a little welcome sea breeze by and on the water around Harwich and Felixstowe Dock. Our first port of call was Harwich Beach, an interesting area of low sand dunes, rich in specialised, often drought-tolerant plants.

The first small stretch of beach featured White Ramping-fumitory and Sea Beet, alongside fleshy Sea Sandwort, waxy-leaved Lyme Grass and tightly rolled but flowering Marram.

Moving around the corner to the larger beach, we were among Dittander (tasting of horseradish) and Rock Samphire (with more than a hint of diesel); Sea Holly and Sea Spurge; Red Valerian (in both red and pink forms) and Japanese Rose. The latter is hated by many, given that it can be invasive and overwhelming on sand, but this patch has barely  grown since I first saw it three decades ago. Bees love it, and so do I: the most intense rose scent you could ever imagine!

With views across to Landguard in Suffolk, shells on the beach were many and varied, including Portuguese Oysters, Common and Slipper Limpets, Periwinkles and Cockles. Then above the town Swifts were screaming, and on the grassy Mallow-covered banks, several Meadow Browns and a couple of Painted Ladies, probably newly emerged rather than newly arrived, given their pristine plumage.

Back through Harwich, past the many historical sites, and the geological display of ice-transported boulders dredged from the channel when it was last deepened; and also Jersey Cudweed, once an extreme rarity but now an expected colonist of block paving.

To Ha’penny Pier where most boarded the foot ferry to Felixstowe, a 15-minute crossing on flat calm seas, ideal opportunity to see the port and its shipping relatively close up. It is a remarkably complex bulk operation, but it does beg the question ‘how much of the stuff in those boxes do we actually need?’. Fast fashion has a lot to answer for…

A beach landing at Landguard led straight to the Viewpoint Café and a very pleasant lunch, before we headed out for another hour on foot around Landguard Point, taking a large loop around the perimeter of Landguard Fort, a strategic defensive establishment protecting the harbour over the past few centuries.

But for us it was the shingle flora that was the attraction, including Yellow Horned-poppy, Sea Kale and Viper’s-bugloss on the more bare shingle…

…Biting and White Stonecrops, along with Rest-harrow, in areas with greater vegetation cover (albeit heavily Rabbit-grazed)…

… and maritime scrub, incorporating Wild Privet (scenting the air alluringly and extravagantly), Tamarisk and Duke-of-Argyll’s Tea-tree, in flower and fruit.

Aside from the plants there were plenty of Linnets bouncing and twittering around the scrub, noisy packs of unruly teenage Starlings. Jude’s sharp eyes located the nemesis of some unfortunate caterpillar, covered in the eruptant pupae of a parasitic wasp, and in a final flourish, we found a Treble-bar moth, not surprisingly perhaps given the abundance of its St John’s-wort food plant on the peninsula.

And so it was back home once more on the ferry, and for most of us a very welcome drink in The Alma! This is likely to be our last WildEssex walk for a few months: thanks to those who have joined us today and earlier in the year. we went out on a high – and we WILL be back!

#WildWivenhoeWalks: botanical highlights along the sea-wall from Wivenhoe – saltmarsh, grazing marsh and block paving!

A lovely walk was had by our group on a dull and rather chilly morning along the sea wall of Barrier Marsh, downstream of Wivenhoe in late April.

Quite unintentionally, the theme of Native/Non-native developed as we looked at various plants in flower along our route.  Hard to avoid at this time of year is Alexanders, a robust plant which is not a native, though a long-term inhabitant, brought here by the Romans (being fully edible), and is rather contentious, being thought of as a thug by some.  The current climate suits it well and it now flowers from March, just at the time when our insects are waking and need sustenance.  Our ‘native’ plants are often not in flower so early in the year, but our insects are up and going earlier and earlier due to the collapse of our climate, with our mild winters and so need this plant to survive. On sunny days particularly it is alive with insects of all sorts – not so today given the cool wind.

Cow Parsley, once thought of as the harbinger of a richness of summer beasties, was only just coming into flower …. too late for the modern first flush of insects.

So the discussion had begun – does it matter if a plant is ‘native’ or is an introduction?  The answer is an emphatic No!! – if a plant can provide for our pollinators when they need pollen/nectar then, with just a few exceptions, they should be welcomed. Other non-natives that certainly pay for their keep in our countryside included Three-cornered Leek and Large Mediterranean Spurge.

As we walked we looked at various plants, starting with English Scurvygrass, the first inkling of summer and autumn saltmarsh shades.

Along the sea wall there were plenty of buttercups, all showing the downturned sepals characteristic of Bulbous Buttercup and very few others, although the photo shows a potential pitfall – those on the left are fresher flowers and the sepals have yet to turn down…

Not in flower, but readily identifiable by the ‘scrunch and sniff’ test was Sea Wormwood, on the seaward face of the sea wall, bearing the scent of absinthe, apparently. So, one in the eye for the apps there!

The block paving around the Barrier also produced a fascinating variety of small, white flowered crucifers (Brassicaceae), all very similar in flower but easily differentiated by their seed pods: long and cylindrical (Thale Cress); short, fat and heart-shaped with a septum at right angles to the plane of flattening (Shepherd’s Purse); and short and oval, with a septum along the plane of flattening (Common Whitlow-grass)…

And finally, a real surprise. While we have found Cornsalad sporadically as a colonist of block paving hereabouts, we found lots today, sheets of it, more than we have ever seen before:

An excursion down into Barrier Marsh was interesting from the historical point of view (the path, ‘The Chase’, originally belonged to the otherwise landlocked Elmstead Market and was their access to the water for trading purposes). Also the many, many anthills are fascinating  – much more numerous and larger on one side of the path than on the other, the disparity due to the side nearest Wivenhoe being commissioned as agricultural land during the war and used to grow vegetables – so their numbers only began building since the 1940s as opposed to 400+ years ago on the other side.  The anthills weren’t really flowering at their best just yet – each is a microcosm with its own community of tiny flowers which are aided by the warmth and well-drained soil produced by the activities of the ant colony below and will certainly be worth a look after the forecast heatwave next week.

However, one of the nationally scarce plants of that marsh, Divided Sedge, was in full flower, forming very dense swards, and led naturally to a discussion about the differences between grasses, sedges and rushes, and then the diversity of flower structures in the grasses, an important part of their identification, as covered in Chris’s new book…

As usual Jude was on the lookout for insects.  Not a huge amount on the wing given the cool conditions, but a couple of interesting beetles were discovered.  Neon-striped Tortoise-beetles were on Sea Beet next to their holes, a regular spot to find them, from now for the next month, but a beastie we have never found elsewhere in the area. And on the same plant, a couple of 24-spot Ladybirds, next to some ‘grazings’ – maybe they’d had their dinner first to get the strength for their subsequent activity!

And a couple of things with very different ways of not being eaten: the caterpillars of Brown-tail moth, largely protected by irritant hairs, and a micromoth Notocelia cynosbatella, basically a bird-dropping!

While we don’t focus especially on birds, treating them on a par with all other wonders of nature, they certainly made their presence known, with singing Cetti’s Warblers, Whitethroats, Lesser Whitethroats, single fairly distant Nightingale and Cuckoo, and a swooping Swallow. So all in all, a very varied couple of hours, and as usual we would like to thank everyone who joined us for our amble for their interest and involvement.

*********************************************************************************

By way of a prologue, to reinforce what we wrote above about the enduring value of Alexanders to early insects, it is worth going back fewer than 24 hours, when we walked from Colchester to Wivenhoe along the trail. The weather could hardly have been more different: calm, sunny and really rather warm. And the Alexanders was buzzing with all manner of insects. Most obviously it was the St Mark’s Flies, emerging a day before their appointed date, all dangly legs and carrying their loads of pollen in their abundant hairs.

There were also numerous nomad wasps zipping around, together with a more stately Box Bug, our first of the year. And an Alderfly hiding under one of the leaves.

And then the specials. Firstly, the grass bug Stenodema calcarata: although not rare locally, we don’t see this with any regularity. And then the Plain-winged Spring Bee-grabber Myopa testacea, again not uncommon nationally but it would appear with only two previous records in north-east Essex.

Alexanders is truly a bedrock of biodiversity!

#WildEssexWalks: hunting the Elves – in Cockaynes Reserve

We went in search of Elves and were certainly not disappointed!

Our first walk of the year, to Cockaynes Reserve, was a most enjoyable event. We got off to a rather damp start but the rain soon stopped and the sun came out –  it was so nice to have the chance to catch up with some of our old friends in this familiar and well-loved place.  This time all proceeds are going to the Save the Old King George Oak appeal and we would like to thank everyone for their contributions – all monies now forwarded via the Crowdfunder page. If you would like to read Chris’ wise words about this whole shenanigans you can via his blog Saving Wivenhoe’s Old King George Oak Tree | Chris Gibson Wildlife.

And so to the Elves (rather the Scarlet Elf-cup fungus) – wow, what a wonderful display this year! Many times more than we have ever seen in the past 14 years of living in Wivenhoe- indeed possibly since Chris first found them here in 1986.  Unsure why – maybe the disturbance caused by the remaking of the path a couple of years managed to spread the spores, or the damp spring has just made their existence more viable? Whatever the reason they were a joy to behold, and seemingly spreading to previously Elf-free sections of Villa Wood. A truly iconic species for this reserve.

And these were not the only fungi to be found. Turkey-tails and Maze-gills  were on rotting stumps and King Alfred’s Cakes and Jelly Ears on Ash and Elder trees respectively.

Within the lush mossy greenscape alongside Sixpenny Brook (running very muddy after the overnight heavy rain), there were flowering Hazel bushes, male tassels in abundance, while Jude found one plant in which the little red female flowers were just emerging.  There were also Lesser Celandines (some with beautifully marked leaves, variegated in both black and silver) and the first Opposite-leaved Golden-saxifrages in flower, always good to see as a sign that Spring is just around the corner.

Elsewhere, plant-wise it was a pleasure to see Gorse in full flower (well, kissing IS in season 😉), Winter Heliotrope on the side of Ballast Quay Lane, as well as early-flowering Red-Dead-nettles and Common Field Speedwells, as well as the tentative spikes of Bluebell and Wild Arum leaves pushing up.

Out on the heathy areas, it was too early for flowers, but the spore-capsules of the Juniper Haircap moss made for a splendid vista among the Reindeer Lichens.

Spring was in the air with bird life at every turn including flocks of Goldfinches, Linnets and Chaffinches, and Skylarks singing along the path up to the reserve; while there at least three Song Thrushes serenaded us, plus Wrens, Robins and a Chiffchaff (the first we have heard this year – so early in the season it must have stayed here all winter, rather than migrating as they did of old). Mixed bands of Great, Blue and Long-tailed Tits rampaged through the woods and scrub, and generally gave the impression of Nature waking up in anticipation of Spring!

We feel we have well and truly kicked off our Wild Essex season and look forward to the next event next month (bird watching starting at Manningtree Co-op).

#WildEssex New Year Plant Hunt 2025

Each year, the Botanical Society of Britain & Ireland organises a New Year plant hunt, encouraging botanists and other interested folk out of their midwinter slumber to see what plants are flowering. And traditionally this has been our first #WildEssex event of the year, a walk around Wivenhoe Waterfront on New Year’s Day. Sadly not in 2025: as seems to be getting more frequent, we were subject to a severe weather alert for strong wind and heavy rain so for reasons of comfort and safety we took the decision to cancel.

All data collected in this citizen science project are fed into the national record of what is flowering at this time: for more information see New Year Plant Hunt – Botanical Society of Britain & Ireland (bsbi.org). It is good to be part of a bigger project to aid learning about how British and Irish wildflowers are responding to climate change, so it is fortunate we did a recce a couple of days prior to our planned walk, applying the same rules, and more or less following the same route as in previous years.

Our recce produced the ‘usual suspects’, shrubs that routinely flower in the depths of winter and annuals that flower at any time of year: Gorse, Hazel, White Dead-nettle, Groundsel, Annual Mercury, Shepherd’s-purse, Hairy Bittercress, Sun and Petty Spurges and Common Chickweed were among those we found, together with Daisies and Dandelions sparkling sparsely in lawns. 

Some of the older walls and brickwork supported Mexican Fleabane, Trailing Bellflower and Ivy-leaved Toadflax, while other showy plants included Green Alkanet, Greater Periwinkle, Pot Marigold, Sweet Violet and Common Knapweed.  And it was quite a surprise to find Ivy flowers still open in places.

Along the waterfront itself, in the cracks of the block paving, Four-leaved Allseed is more abundant than it has ever been since its arrival here around the time of the pandemic, but try as we might we could not find any in actual flower. But other subtle flowers such as Guernsey Fleabane and Pellitory-of-the-wall made it onto our list after close scrutiny, a real test for my newly-decataracted eye! The rapidly spreading Water Bent also increases in abundance every year.

On the salt-marsh, a few Sea Aster flowers remained from late summer, and some spikes of Common Cord-grass dangled their naughty bits wantonly to the wind. But much more dramatic were the very numerous, huge fruiting bodies of Cord-grass Ergot, a fungus we found around here less than a decade ago and which now seems very prevalent.

Carrying on the seaside theme, three plants we have not recorded before on these forays are garden escapes that have put on their first flowering appearance outside the confines of cultivation: Sea Campion and Rock Samphire, native plants of sand and shingly beaches, and Sweet Alison, a familiar bedding plant, but often found wild in coastal areas, as reflected in its scientific name Lobularia maritima.

All in all, 37 species in flower represents a new high for us (see full list here New Year Day PLANT HUNT Year on year) compared with 34 in 2024, 23 in 2023, 35 in 2022 and 30 in 2021, although one should fall short of celebrating – many of these plants should not be flowering now, and are doing so only because of the harm we have inflicted upon our climate…

But our feeling was that while we saw more species in flower, there were fewer flowers of each species to be found: the landscape was much less floriferous, more akin perhaps ‘proper winters’ of decades past. I got exactly the same impression at Boxted the day previously where I led a village wildflower walk for the second New Year in succession.

There is of course another way of looking at it. Plants are not the only things responding to climate change: although we saw no insects being active in the dully, foggy weather of our walk, it is undeniable that fewer insects are hibernating than used to be the case. And year-round activity needs year-round nectar and pollen resources, so any insect-attracting flowers such as Gorse and dead-nettles are important, even in the context of much richer supplies inside our gardens, as for example the gorgeous, subtly showy blooms of Virgin’s-bower Clematis cirrhosa.

While there is a little turnover of species year upon year, in some way there is also comfort to be found in the litany of names, old friends in many cases, even down to actual individual plants, recited in a ritual that echoes that of the Shipping Forecast. In spite of our best efforts at self-destruction, the world still turns! Happy New Year!!

 

 

 

#WildEssexWalks: autumn in the Wivenhoe Cemeteries

#WildEssex today resumed its tradition of offering a fungi walk in November.  This year we stayed local to Wivenhoe, exploring both cemeteries to hunt out not only fungi, but also foliage, fruits and an interesting addition to our town this year – Firebugs! An ‘effing’ good time was in prospect!!

But the weather dampened things a little. Light rain for much of our two hours (we stayed in the wooded Old Cemetery when it turned more purposeful) gave way to occasional warm sunshine, and a magnificent double rainbow. And the raindrops certainly embellished the tips of the beautiful Bhutan Pine…

The fungi are always unpredictable, even in these cemeteries, renowned as one of the best locations for fungus-hunting in the area. But this time, we managed to hit the peak (probably) of a good year. Under the trees there were numerous Death Caps (appropriate for cemeteries!), a single Fly Agaric, parasols and Clouded Agarics:

In addition we discovered fungi growing on dead wood (Turkey Tail types) and microfungi on leaves: Sycamore Tar Spot plus various rust fungi, not to be confused with leaf-mines, galls and other blemishes:

In the more open New Cemetery, the important grassland fungi put on a great show, with six or more waxcaps, from white, through yellow, orange and scarlet, to black; Golden Spindles; puffballs and earthballs; milkcaps and cheesecaps; plus numerous LBJs  (Little Brown Jobs).

In a footnote to the above, just a couple of weeks after this walk, we were out on the King George Field. Grassland fungi were coming up there too, including at least four waxcaps and one club fungus (photos below). I have not seen fruiting like this at this location here since 1987. It was this half-remembered diversity that guided my choice of the southwest corner for the first Wivenhoe haymeadow seven years ago. Comprehensive fungal survey certainly needs patience!

And the rich flora was not completely over either, with Field Scabious, Mouse-eared Hawkweed, Ox-eye Daisy and Yarrow still flowering, although the Ivy Broomrape (possibly its only site in Essex, discovered this summer) was well over. Having said that , as a parasitic plant with no chlorophyll it always looks dead anyway!

Fruits abounded on Cotoneaster, Holly, Yew, Ivy and Stinking Iris – all important resources for birds:

And autumn-tinted foliage lit up the paths as we walked through the cemeteries:

As always we were on the look-out for insects. Some gravestones (particularly those under Lime trees) proved popular meeting places for large numbers of Firebugs. These lovely creatures have only been known in UK for a few years, and now have a foothold here in Wivenhoe. How they manage to disperse and spread is all rather mysterious as the vast majority of individuals do not have wings and so cannot fly.

Other invertebrates included a rather splendid ichneumon wasp, Virgin Bagworm moths and a single Parent Bug, while the final discovery of the day was an Issus coleoptratus, a bug which we have seen very few of in recent years.

In addition to general nature walks, this year WildEssex have introduced ‘Botany Club’ events. These are for anyone interested in learning more about the craft of identifying wildflowers, and no previous experience is required.  Using Chris’ book ‘British & Irish Wild Flowers and Plants’, a few samples are collected each time and then the process of identifying explained. More events of this type are to be arranged next year. For more details of these, or our other, events please contact Jude at jmgibson1959@btinternet.com.

#WildEssex Walks in Progress: Station-to-station through the heart of Colchester

The third of our recent trips to investigate potential new nature walks was much closer to home, starting just one stop down the railway line at Hythe, and walking the route of the River Colne up to Colchester main station three weeks ago.

Particularly the earlier part of the walk we knew well in the past, both having worked in Harbour House at the Hythe, but that finished 15 years ago. It always was a pleasant walk, but would the same be true now, especially given the litter-strewn route the last time we ventured there maybe five years ago?

The Colne is in two sections, tidal in the lower reaches, but above the sluice at East Mill, non-tidal and sluggish. At times of low flow, little water spills over the sluice so the section below is not only tidal but salty, as evidenced by Sea Aster and other saltmarsh plants growing along the muddy margins.

The first section of the walk was across the Moors (historic moorings, not uplands swathes of Heather!). And what a change there has been, with spontaneous woodland now springing up on this brownfield site, areas of which were a disposal site for Paxman’s factory spoil. No room now for the Wasp Spiders we knew so well, and the former swathes of interesting plants like Tree Lupin and Wormwood are much reduced, but the riverside scrub held at least three singing Cetti’s Warblers, almost unthinkable when we first knew it.

Flowering Ivy bushes sporadically along the path, as always, were a magnet for late-season insect activity, including Ivy Bees, Honeybees, bumblebees, Commas and many more.

The only areas remaining unwooded are the flood-prone sections now clothed in beds of Russian Comfrey and Stinging Nettles, botanically poor but supporting lots of insects, here  Parent Bugs and a Dock Bug, and lots of spiders.

Nettle and Comfrey both love high nitrogen conditions, probably derived from flood overspill. Colchester sewage works forms one of the main tributaries of the Colne: it may be downriver but on a flood tide its effluent will be pushed upstream. And probably again and again as it takes several tides for water entrained in the upper tidal reaches to finally exit to open sea.

Another feature of the water was the slick of lurid green Least Duckweed. The source of the duckweed was obvious when on the bridge over the sluice next to East Mill … the still river upstream was chockfull after a few days without rain. There was only the merest dribble of water passing over, the duckweed discs jostling like coins in the penny-falls of an amusement arcade on Clacton Pier. But after heavy rain, the downflow of duckweed will be greater, and indeed the sluice may be lowered periodically to clear the river, as we have suspected when the green slick passes our flat.

Along the tranquil upstream stretches, Alder trees and various willows form stands along the banks, the Alder leaves bearing the tell-tale holes of the recently arrived Alder Leaf-beetle and an array of mite-induced galls. in these spots, several Grey Wagtails were feeding, and a Kingfisher sped past in a moment of brilliance.

Moving upstream away from the sluice, the water became clearer of duckweed, and revealed a number of other water plants such as Arrowhead. In such spots in the sun, Migrant Hawkers and Common Darters were feeding and breeding while Willow Emerald damselflies flittered among the  branches, and a Forest Bug teetered on the brink of disaster wandering around the leaves overhanging  the water.

At lower Castle Park, it was time for a diversion away from the river. No time to examine the impressive array of ornamental trees, but we had to stop and enjoy a Rose Chafer that flew in from nowhere and landed right in front of us. Colchester is a national hot-spot for this magnificent beast, but the mid-September date seemed rather late.

Running between Upper and Lower Castle parks is a superb section of the Roman city wall, constructed substantially of septaria nodules front the London Clay exposures around Harwich.

This is the site of one of my career failures. Thirty or so years ago, the wall was visited by an eminent lichenologist who rated the diversity of wall lichens he found one of the highest in Eastern England. And then another expert, this time on an even less celebrated group,  lichenicolous fungi, came along and found several species new to Britain and some new to science. I pushed for the wall to be given SSSI status; English Nature’s council had other ideas. Too obscure an interest, and not wanting to get into a fight with English Heritage on whose call Colchester Borough Council was proposing clearing, cleaning all vegetation from the wall.

My intervention may have done some limited good, but walking along the north-facing wall this week it seemed rather less special for wildlife than it was previously. Having said that, still some specialist wall plants, including Pellitory-of-the-wall, Red Valerian (with its distinctive bug gall), Oxford Ragwort, Yellow Corydalis and even some local scarcities such as Wispy Willowherb, Fern Grass and Black Spleenwort.

Also on the wall were mating orgies of picture-winged cranefly Tipula confusa, for which the Essex Field Club map shows only a couple of sites in north-east Essex (Earls Colne and Walton). However maps are not always complete, and indeed a niggling memory was tracked down to a photo of one we found in Bures. And then one in the ferry port of the Isle of Coll – it would seem not to have been recorded on that island before. Always something to find, and learn, and share… a salutary lesson always to send in interesting records!

Back to the river, we continued across Middleborough and right then round to Cowdray Avenue, with a happy short detour for an excellent lunch in the Marquis pub.

So, another interesting walk for us to offer in due course. Interesting also to see parts of Colchester previously unknown to us, despite having lived and worked there. And it was also very pleasing to note the lack of litter along the route, a tribute to the efforts of Colchester City Council or volunteers or whoever does the selfless, and all-too-often thankless, task.

*************************************************************************************

Three weeks later we returned to do this as a walk with eight happy walkers, enjoying the return of blue skies and sunlight, although unfortunately the litter-free nature of our past walk wasn’t repeated. However, given that we had at least three Litter Faeries with us, our group certainly made a positive difference. Thank you for all your efforts!

There were changes over the three weeks, mostly reflecting the onset of autumn. There were fewer insects, with just a few Red Admirals and a Dock Bug, along with bumblebees feasting on the final Comfrey, Bristly Ox-tongue and Ivy flowers. But we did find a couple of (sadly) squashed Rose Chafers, further extending their flight period which even in September seemed longer than any we had experienced before.

Festoons of Traveller’s-joy were more Old Man’s Beardy while those of Virginia Creeper on the Moors had assumed the ‘traditional colors of a US fall’; in Castle Park, our trees were making their own subtle colour-shifts. Perhaps the fact that last night we almost had a frost will produce one of our periodically spectacular autumn fire-shows, which would resonate well with the second major aurora event reported around Colchester last night (not by us!)

The non-tidal section of the Colne above East Mill also looked very different, lacking the thick carpets of Least Duckweed. Occasional rather heavy rainstorms have clearly pushed the mats of duckweed discs over the precipice of the sluice into the salty tide, and so to oblivion. There was a family of Dabchicks on the upper sections, birds that will voluntarily head downstream shortly as the risk of icing on fresh waters increases.

Galls are always a feature of autumn, such as these Spangle Galls on Oak leaves, and there are then of course the fungi. Their high season is just starting, and will be a feature hopefully of the next #WildEssex walk…for today, it was Sycamore Tar-spot  and a troop of Shaggy Ink-caps in all stages of development.

And so it was lunch in Castle Park followed by a welcome drink in the Marquis as a fine full stop to the event, one that may become a regular offering, suitable for any time of year.
