#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, bur 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.

#WildEssex on Tour: across the border – to Felixstowe

Following two previous successful #WildEssex on tour events, to Harlow last year and Burnham in 2022, this time we ventured abroad (out of the county!) to Felixstowe. A different county maybe, but Essex was in sight for most of the time…

We assembled at lunchtime on the first day at the Alex, for a fine snack and a drink. We had been worried by the wet and windy weather forecast but it was warm enough to sit outside, and the sun even came out for us. Indeed the weather gods were on our side for all three days: the threatened heavy, prolonged rain came when we were indoors or asleep, and the only time we got really wet was walking home from the station at the very end.

Our first afternoon was spent examining the Felixstowe seafront and gardens. Looking out seaward gave some idea of the busyness of the shipping lanes out there, with some huge container vessels on the horizon looking more like the Manhattan skyline than anything afloat.

Large rock groynes provide an artificial rocky shore habitat, with seaweeds, limpets and other marine life. As we looked at an array of shells found on the shingle beach, a Red Admiral plonked down next to us. A very fresh individual, it was probably migrating southwards, something that has been happening en masse over the past couple of weeks.

The planting on the cliff slopes is largely Mediterranean shrubs, some still in flower, others in fruit…

Best of all for insects though, as always at this time of year, was the flowering Ivy, abuzz with Ivy Bees, Honeybees, bumblebees and hoverflies, all a rich source of food for the Garden Spiders.

The Holm Oaks were absolutely riddled with leaf-mines from the micromoth Phyllonorycter messaniella, to a greater extent than we have seen elsewhere. Although a bit unsightly, such infestations apparently don’t affect the tree significantly, and each mine contains a mini-morsel for a Blue Tit – it is good to see a non-native tree that is likely to be a big part of our future landscape garnering its own ecology, fitting it to its new home.

The geology of the cliffs, with gravels over clays, means there are springs, which have been tamed and corralled into water features, some dripping with newly formed tufa, ponds with Curled Pondweed, Watercress and Monkeyflower; pond-skaters skittering on the surface; and rocks covered with Ivy-leaved Toadflax.

Grassy slopes had Wild Clary in flower, and the lower, salt-splattered lawns were clothed in the attractive rosettes of Common Stork’s-bill and Buck’s-horn Plantain. And cracks on the promenade were colonised by Guernsey Fleabane and Water Bent, two relatively new plants in these parts, but again likely to be a big part of our future in an overheated world.

A walk along the prom, via a cuppa in the Spa Pavilion, finished the afternoon, with most then opting for dinner at the Premier Inn. But no takers for the batting option in Langer Park!

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

Next day dawned dull with spots of wet in the breeze. As we headed to the north side of town on foot and by bus, a patch of Caper Spurge weaved an interesting pattern …

… and the view out to sea reflected to rather dismal weather.

Heading towards Felixstowe Ferry, we soon diverted onto vegetated shingle, an internationally important habitat type and one for which Suffolk is justifiably renowned, the realm of Sea Kale and Sea Pea, Sea Campion and Sea Beet, Sea Holly and Sea Spurge … quite a theme developing there!

Down by the saline pools there was a saltmarsh of Sea Purslane and Annual Seablite, now assuming its diverse autumn tints, but few birds apart from gulls (including a Great Black-back), Cormorants and a Little Egret.

Continuing along the seawall, past the Martello Towers, we found plenty of botanical interest, including Lucerne (purple), Sickle Medick (yellow) and Sand Lucerne, the remarkable hybrid between the two in a whole range of intermediate and extramediate hues.

White Ramping-fumitory was  in good flower, and there were plenty of (soggy) seed-heads, including Hare’s-foot Clover, Rough Dog’s-tail and Bristly Ox-tongue in a veritable botanical menagerie.

 

Here Jude also spotted several Firebugs feeding upon Mallow seeds, a very recent arrival first found across the water around Harwich in the last five years, and Turnip Sawflies, in a similar colour palette.

Having discussed (and in some cases tasted) foods from nature on the shingle (pea, kale, holly and beet) we soon found ourselves among more edibles and flavourings, including Fennel, Duke of Argyll’s Tea-tree (goji berries), Dittander (like Horseradish), Sea Radish and, best of all, the mini taste-bombs of Crow Garlic bulbils, a revelation even to me. The Suffolk coastal paleo-diet seems an apt descriptor, except of course that many of these plants we simply not here in ‘paleo’ times!

Into Felixstowe Ferry hamlet, with Bawdsey Manor in sight, we headed into the Ferryboat for liquid refreshment, while once again the sun came out and warmed things up, before the foot ferry to Bawdsey Quay took us to a lovely picnic spot overlooking a tranquil Deben Estuary.

.

At our feet was a small sand dune with Sea Holly, Sea Mayweed and Marram, with a drift-line of Sea Rocket, Frosted Orache and Prickly Saltwort.

The rocket and related crucifers were being absolutely demolished by Large White butterfly caterpillars.

In the humid air, Migrant Hawker dragonflies were flying around in force, while along the woodland edge a few insects were tracked down, including Nettle-tap moth and a pair of the long-legged flies Liancalus virens. Normally associated with waterfalls and fast-flowing streams, and therefore mostly found in the western half of the country, there is one previous record on the NBN Atlas from around Ipswich, and in Essex at least there is a concentration of records from the estuarine fringes.

Juicy brambles and Alexanders seeds (like aromatic peppercorns) were added to our seaside banquet as Robins were singing their wistful autumn songs in the trees, which included several large Turkey Oaks. The Holm Oaks here had leaf-miners, but mostly the smaller galleries of Ectoedemia heringella, along with pimple-galls caused by gall-mites. Lime and Field Maple also showed mite-galls, impressively so in the case of the lime nail-galls,  while Field Maple and Sycamore showed distinctive signs of fungal attack, mildew and tar-spot respectively.

But as the afternoon was progressing, it was time for the return ferry, into Winkles café for a cuppa, then the walk back, past migrant Wheatears, some Tamarisk in full bloom and a Devil’s Coach-horse with upcurled abdomen, alarmed and alarming in equal measure.

The return buses were so infrequent and the clouds so threatening that we decided to walk the whole way back along the prom (or as near as we could when diverted), to the Boardwalk Bar on the pier for rehydration purposes and sunset, the Fish Dish for a splendid meal. And for some a more leisurely return to the Boardwalk afterwards….

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

A rainy breakfast time on the final day soon dried up; the sun came out but the wind rose, scuppering the plans of some of the group to take the Harwich Foot Ferry home in the  afternoon. But time for a good couple of hours on Landguard Point and Common, a great vantage point to watch the incessant port activity and comings and goings of shipping, and recognize the internationally strategic value of this location, now and in the past – the reasons for the Fort and the bird observatory being there, defence and migration study respectively.

At the seaward edges of the shingle peninsula, lines of Oraches, including Babington’s, and Prickly Saltwort picked out the drift-line.

Moving inland, impressive patches of Yellow Horned-poppy, untidy but still just in flower, mingled with Sea Kale again.

Sandier patches were dominated more by Sea Spurge and Sea Holly, with a few plants of Ray’s Knotgrass, never an easy species to track down.

One the more stabilised dune- and shingle-heath shingle Heath, Reindeer ‘Mosses’ and Sandhill Screw-moss dominated large patches, with  Common Stork’s-bill (in flower this time), Sticky Groundsel and Sand Cat’s-tail, plus last few flowering Viper’s-bugloss.

    

Despite the wind, a few birds on the Common included feeding Pied Wagtails and Meadow Pipits, with twittering Linnets in the bushes and Starlings overhead. Then to the oldest part of all, vegetation-wise, the shingle scrub with Elder and Wild Privet. In the shelter and sun, there was plenty of insect activity including a Box Bug nymph and more Common Blues than we have seen put together over the past summer…

All that was then left was to head back to the Viewpoint Café for a superb (late!) brunch, passing Narrow-leaved Ragwort and Jersey Cudweed on the way, more new plants potentially brought in by the port trade.

And after a great three days, time for fond farewells, all without getting seriously wet: WildEssex 1, Met Office 0! Thanks to all who helped make it such fun!!

#WildEssexWalks: Harwich town and beach

Despite disappointment that our proposed ferry trip to Felixstowe wasn’t possible due to windy weather, we nevertheless thoroughly enjoyed half of our planned day’s event – a morning’s walk around Harwich – the Wild Essex event for September.  The ‘après walk’ of lunch in the Pier Café and a drink in the Alma only added to the fun and we’d like to thank everyone who came along.

Harwich with its many historic buildings was once a busy and thriving port, but today had a relaxed air of an out-of-season holiday destination, with few other visitors. And the cracks of the pavements were filled with interesting plants such as Shaggy Soldier.

We had the beach to ourselves, which gave a free rein to admire and study the plants which thrive in this most inhospitable of habitats: Sea Rocket on the strandline, Lyme Grass, Rock Samphire, Sea Spurge and Sea-holly on the low dunes, although the latter especially was looking very frazzled after the midsummer heat and drought.

Greenest of all was the clump of Japanese Rose, also with its large lustrous hips and a few extravagantly scented flowers. An aggressive spreader in some circumstances, it was good to see it has remained pretty stable since we left the area a decade ago.

We did a quick roll-call of shells on the beach – cockles, mussels, oysters, limpets, slipper-limpets and whelks to name but a few, but although we hunted high and low we weren’t fortunate enough to find any of the fossilized sharks’ teeth which we know reside on the beach.  It’s one of those things – sometimes you’re lucky and sometimes not!

Of course we managed a spot of birdwatching whilst there, with Sandwich Terns passing by noisily and fishing just offshore,  a medley of different gulls providing aerial entertainment and  Turnstones feeding unobtrusively on the rocky, weed-covered shoreline of the Harwich Stone Band, the only natural rocky shore between North Norfolk and Kent.

The few insects around (there had been quite a temperature drop overnight) included plasterer bees feeding and fighting (or frolicking?) on flowers of Bristly Oxtongue: the bees were probably Sea Aster Mining-bees, though related species are very difficult to tell apart.

On the other side of the estuary the comings and goings of the busy port of Felixstowe were interesting to view, as were the various arrays of wind turbines, very visible in the clear morning sky.

We hope to rearrange this trip next year – aiming for early summer rather than late, in the hope that the weather will be calmer and the ferry will be running.

Wanderings in Wivenhoe’s Lower Lodge

Midsummer in Wivenhoe and our attentions turn to Lower Lodge, part of the Colne Local Nature Reserve, a riverside area of grassland and scrub, the wilder bits of which are managed on a three-year mowing rotation by Colchester City Council. Rich in flowers, it is one of our areas of greatest insect diversity, so in the month from late June we made four visits there, a recce and with WildEssex and BNA groups.

Actually this year, at least at first, flowering (and hence insect abundance) was poor, a consequence of a cool spring and of the vigorous growth of tall grass, no doubt reflecting the unprecedentedly wet past six months.

But towards the end of July, flowers were coming through, and butterflies were coming out, albeit not (yet?) in the number of variety we have come to expect.

Meadow Browns as always were followed sequentially by Gatekeepers and then Ringlets, with a few Small Heaths around the mown paths …

… Large (mostly early in the period), Essex and Small Skippers (later on) …

… while summer-brood Commas and Green-veined Whites came out on cue.

As far as day-flying moths are concerned, the few Burnet Companions were not at all companionable, coming a couple of weeks before the first Six-spot Burnets: the latter emerged in force on our last visit on 21 July, when we also found a Silver Y at rest.

Despite the abundance of Ragwort, Cinnabar caterpillars were distinctly patchy, perhaps reflecting poor weather during the adults’ earlier flight period. And another ‘caterpillar’ was of a sawfly, many of which have distinctive larvae, but they are generally beyond our identification skills given the lack of readily available identification guides.

Lepidoptera and other insects are at their best in warm, sunny weather and when nectar- and pollen-rich flowers are open. Therein lies the value of this site, from the earlier-season Common Cat’s-ear and Red Clover, to Wild Carrot (with insect-mimic central flowers) giving way to Hogweed and its vast plates of insect food, available to all, and then Common Knapweed and Field Scabious.

Other lovely flowers included Hedge Bedstraw, Smooth Tare and Grass Vetchling, although by the last walk the latter had retreated into anonymity as its flowers had finished.

And also of course the grasses, here Cock’s-foot  and False Oat-grass in full hayfever-inducing glory!

As for other invertebrates, a few to be mentioned by name are Hogweed Bonking-beetles (out in force and living up to their name), Thick-thighed Beetle and Black-and-Yellow Longhorn …

… ‘Common’ Earwig, one of those memories of childhood that few of us see nowadays …

… a nymph Tortoise Bug, not a common species in the county and according to the Essex Field Club map almost unknown east of Colchester, while very similar comments apply to the beautiful planthopper Allygus mixtus, although we have seen that previously around Wivenhoe, in the Old Cemetery.

And then just a selection of others, just photos, no words, although all have been identified and a full list will be given to the site managers.

 

It was also good to see plenty of oak galls – marbles, artichokes, ram’s-horns, cherries and knoppers – with only the spangles seemingly at a low ebb, being small and few and far-between.

And finally, always good to see, dispersing Toadlets, presumably having taken advantage of the spring-line pools created by this year’s weather. We may have complained but every version of our crazy weather benefits something!

#WildEssexWalks: Mistley Furze Hill and Old Knobbley

Wow!  A warm summer’s day – what a lovely change – and enjoyed by our group on our Wild Essex walk in Mistley.  Our journey took us through the Edme Malt works, where we admired some of the intricate decoration of these functional buildings, under the railway line and on through a cow field where the residents were curious but friendly.

A walk along a rather attractive footpath reminiscent of a holloway where the tree canopies meet was a cool place to wander out of the sun’s glare and admire some of the wild flowers, Cuckoo Pint, Herb Robert and Hogweed to name but three.

Of course Chris took the opportunity to talk about the characteristics used in his new flower identification guide such as the ‘false insect’ and branched bracts of Wild Carrot, the four-lobed stigma of Great Willowherb and the uniquely two-petalled Enchanter’s-nightshade.

A few galls were spotted including two very different ones on Dog Rose: smooth pea-gall and spiked pea-gall. A complex, confusing and confused pair, the spiked version  belongs to the gall-wasp Diplolepis nervosa though the smooth one could be caused either by D. nervosa or the closely related D. eglanteriae. In this form, the two species are indistinguishable.

At the top of the lane we continued on to the edges of the local amenity field, past the ‘Secret Bunker’ and rather interesting Passive houses. Here there were more stands of wild flowers (including Ragwort, but without stripy Cinnabar caterpillars) and a number of butterflies seen.  Sadly numbers of these insects seems to be quite low this year, at least so far, though by the end of the afternoon we had spotted seven species – Red Admiral, Holly Blue, Comma, Large White, Gatekeeper, Meadow Brown and Large Skipper.

Just a few other insects attracted our attention including a 10-spot Ladybird, a flesh-fly and and a nymph Speckled Bush-cricket.

And on to the main event – through the wood that clothes the flanks of Furze Hill we admired a number of old oak trees, many of which showing signs of pollarding down the ages resulting in interesting branch formations.

At last we reached Old Knobbley Himself.  Well-named,  this 800 (at least) year-old tree is covered in nobbles and lumps – some caused by bacterial infections and galls – but despite its vast age, this charmer still looks pretty fab and very much alive with upper branches sprouting leaves with gay abandon.  It is such a tactile beast we all spent time stroking  and patting the trunk, and spent time imagining what some of the limbs might represent – two elephants, a moose, a stag?

And as we walked round his girth, is it possible the enveloping folds of root and bark were nursing the oaklet that will eventually replace its esteemed forebear?

And so it was time to turn back to ensure we reached our trains punctually.  A little walk along School Lane brought us back to the station and it was time to say our farewells.  Thank you to all who came along, and to everyone who supports our Wild Essex venture.  Hope to see you all again soon.

#WildEssexWalks: Wrabness and Stour Wood

A rather damp and dark evening was the backdrop for our annual Wrabness evening walk (leafy lanes to East Grove with its wonderful views over the estuary, then into Stour Wood itself), however we still found plenty of interest to show our group. We have assembled a selection of photos from the night, many taken with flash as the conditions were so dull while the landscapes became more like Impressionist art!.

This summer has so far been worryingly short of insects, but given the lush vegetation along the lanes, woods and wildflower margins alongside the fields where we were walking, we did find lots of what we would have expected including the ubiquitous Hogweed Bonking-beetles, a variety of shieldbugs, Speckled Bush-cricket, Acorn Weevil and a Hairy Beetle with a couple of stowaway mites.

No butterflies unfortunately, which we hope was only due to the weather conditions, but there was a scattering of moths: one lovely 6-spot Burnet moth, together with a bagworm and Cinnabar caterpillars..

The Wildlife ‘For Bees’ area near Wrabness station itself came up trumps with lots of bumblebees on the Lavender, and proves that just leaving areas to go ‘wild’ isn’t the only way to help our waning wildlife  – many ‘garden’ plants can do the trick very nicely.

As well as insects we looked at some of the many flowers including White Bryony, Oxeye daisies and Knapweed, all of which play a part in providing food for insects.

The moist air of the ancient woods was scented with the mushroomy odour of Sweet Chestnut and the sweetness of Honeysuckle, waiting for the arrival of moths, the night-shift pollinators, while ripening Wild Cherries shone like little beacons.

As we walked we were serenaded by Goldfinches, Skylarks and Wrens. Just one or two birds were spotted on the estuary itself – Black-headed Gulls and a Curlew or two, with Oystercatcher flying over: the winter influx of waterbird migrants is just about to begin. And as if to demonstrate we don’t ignore anything, how about our final offering – the aptly named Dog-sick Slime-mould!

#WildEssexWalks: Brightlingsea East End

Another lovely Wild Essex walk with a group of nature fans from across north Essex. Although we didn’t find as many species of insects as we may have liked, there were still some to admire, as well as interesting flora. We (at least some of the group) finished with a very enjoyable pub lunch at The Rosebud The Rosebud seafood restaurant & pub (rosebudpub.co.uk). It is always nice to complete our walks with a get-together of some sort, and having a lovely backdrop of Brightlingsea Creek with its boats, viewed from the pub conservatory, made the whole experience even better, helped by the quality of food and the speed of service.

The morning weather was warm, varying between overcast and sunshine.  And for this most miserable of summers this in itself was a welcome change. We walked from The Rosebud on Hurst Green, conveniently placed for us that travelled by bus, towards the ‘East End’ of Brightlingsea, via a quiet(ish) road until we got to the Millennium plantation and East End Green where we were treated to the most amazing display of Pyramidal Orchids that we have ever seen here, probably better than anywhere else in the north-east of the count with more than a hundred flowering spikes.  Well worth a visit if you are in the area!

Insects of note include the little Zig-zag Elm Sawfly which does what it says on the tin and creates a rather attractive cut-out on Elm leaves.  We saw some mid-size Dark Bush Cricket nymphs, Thick-thighed Beetles, plus a rather unusual red Beetle on its own in a field 😊

A beautiful picture-winged fly Urophora stylata showed how effective its markings can be in helping it hide in plain sight whilst resting on its food plant of thistle.  Butterflies were surprisingly and rather worryingly in short supply, but when the sun eventually came out we were treated to a few Meadow Browns, Small Heaths plus a Holly Blue or two.  A freshly emerged  Ruddy Darter was a bonus, found just as the walk was coming to an end.

Pollinators in general were few and far-between, with very few bees or flies, again a worrying trend. Spiders could be found sitting around hoping to catch their dinner, including this Cucumber Spider.

Those interested in flowers were treated to a variety of grassland and woodland species…too many to mention them all but they included (Chris’ favourite flower) Grass Vetchling, Pineapple Mayweed ( just sniff those scrunched leaves!), Field Scabious and Ox-eye Daisies (so important for any passing pollinators), White Dead-nettle and Hedge Woundwort. And of course gave Chris (ever the salesman!) the chance to promote his new book, published this very week  British and Irish Wild Flowers and Plants | Princeton University Press.

One of those on the walk, Tony, has kindly provided a provisional list of species we found List of plants and animals seen on Brightlingsea walk of 20 June 2024. Thanks for this.

The Wild Side of Felixstowe

A short break in Felixstowe was ostensibly a recce for our proposed #WildEssexOnTour extravaganza later in the summer, but in reality was jolly good fun as well! We didn’t venture to Landguard this time as we know it so well anyway, but we explored green spaces in the town and also up the coast to Bawdsey.

The first day, spent in glorious warm sunshine, we started along the sea-front, looking at the cliff gardens; they were a revelation, formal yet informal, filled with a wide variety of trees, shrubs and flowering perennials.

The plants are mostly non-native and tolerant of sea-spray and wind: fortunately most, like the sun-roses, are a magnet for bees and other pollinators.

Others included Rose Garlic, with mixed heads of flowers and bulbils, and Red Valerian, much more familiar but in full bloom, showing its almost unique character of possessing only one stamen per flower.

A number of springs emanate from the cliffs, reflecting the local gravel/clay geology, and these have mostly been corralled into formal water-features, fringed with Monkey-flower, and with Curled Pondweed and Water-hornwort in the water.

With such an array of plants and habitats not surprisingly there was plenty of insect life on display, from Holly Blues to tiny Dark Bush-cricket nymphs and Green-palped Sun-spider (with a planthopper for lunch) to numerous nymphal froghoppers drooling ‘cuckoo-spit’.

Even flat, mown lawns were not devoid of interest, some with both Sea and Small Mouse-ears (four and five petals respectively) among the Bulbous Meadow-grass, along with Bird’s-foot Clover (with at most two flowers in a head) and Spotted Medick, all typical components of dwarfed maritime turf.

Heading inland, the Snow Hill Garden had Elm leaves with the distinctive larval munchings and meanderings of the Zig-zag Elm Sawfly, a relatively new arrival in these parts…

… while in Langer Park, a more-traditional manicured recreational space around the remnants of the once-tidal Walton Channel, the trees and nettlebeds produced a huge late-afternoon array of sun-basking invertebrates.

There were ladybirds galore, including Adonis, Cream-spot and the distinctive sexpustulata form of Two-spotted …

… along with weevils, soldier-beetles and a large leaf-beetle with a distinctive ‘gutter’ around its thorax Chrysolina oricalcia, the latter something we have never seen before.

Other insects included Hawthorn Shield-bug, Nettle-tap moth and numerous flies …

… including one hoverfly who spent five minutes laying eggs on a nettle-leaf right in front of us, perhaps up to 20 in total!

Spiders too, including a nursing Nursery-web, a few crabbies and one Larinioides cornutus, with quiff and fancy garters. A truly splendid half an hour by the nettles.

Next morning, the weather could hardly have been more different: dull, grey, cooler and with light rain on-and-off all day. A real surprise then walking to hear a veritable chorus of Swifts flying over; yesterday there has been only a few. It went on – and on – and on – and it soon became apparent that it wasn’t ‘real’ Swifts, but tapes of screaming Swifts designed to drawn in occupants to the array of next-boxes on the Library. All credit to Suffolk County Council for this, even if elsewhere in the area they do appear to be a bit heavy-handed on the glyphosate front along paths and roads.

A bus-ride to the north-eastern end of town took us to within striking distance of Felixstowe Ferry. The shingle beach was covered in froth-topped flowering plants of Sea-kale, while along the edge of the land, there were all sorts of other interesting flowers, including White Ramping-fumitory, Seaside Daisy, Sea Radish and Snow-in-Summer.

Several Silver Y moths were out and about, presumably reflecting a recent immigration event, a nomad-bee (perhaps Nomada flava) nectared upon Sea-kale and several Gorse Shield-bugs gave the lie to their name, feeding (or at least resting and mating) on Sea Beet.

Rounding the corner to the Deben, we took the foot ferry across to Bawdsey …

… where we found flowering Barberry and Sand Cat’s-tail, with a Gorse Shield-bug in its ‘proper’ home bearing more than a passing resemblance to Gorse seed-pods.

And finally, one of our most exciting finds of all, the large, rounded, reddish galls of Plagiotrochus quercusilicis on the new-season leaves of Holm Oak. Caused by a gall-wasp, this again was new to us, and indeed is relatively new to the area, being first found in Colchester as recently as 2018. By now though it could be well established – certainly on our walk back to the station we saw it abundantly in one of the gardens.

A fascinating couple of days and a very enticing prospect for our three-day event later in the year!

#WildEssexWalks: The Bluebells of Wivenhoe Wood

Always a staple in our catalogue of walks, this year we embraced our Bluebells on three separate walks over a week and a half, and this blog is an amalgam of them all. Given the unstable weather this spring, not surprisingly we had a mixed bag, from lovely warm sunshine to cool, cloudy and wet…

In fact the season started early (a symptom of our largely frost-free winter) with the first sign of blue coming in mid-March: we were concerned that the main event would be over before our walks even started.

But then the gloom of April and cool northerlies slowed things up, and even by our final walk on May 4th, there was still plenty of blue, albeit looking distinctly worse for wear.

Peak Bluebell was around the date of our recce, April 26th, when lovely sunshine lit up the blue swathes and helped contribute to a scentscape like no other.

As always we noticed a few naughty Spanish Bluebells and their hybrids: hopefully Colchester City Council will take action in line with their biodiversity duty.

But one of the lasting impressions this year was of mud. Springs springing out in places where springs have never sprung before, at least in my almost 40 years of knowing this wood: the sign of an unprecedentedly wet start to the year.

The other thing we noticed was that the overall showing was a tad less impressive than we have become accustomed to in recent years. Of course this could be weather- or climate-related, but probably more likely is that the coppice plots are growing up, and starting to cast shade sufficient to suppress the Bluebell show. If we want our Bluebells en masse, we need active coppicing to continue, something that sadly is not always assured given local authority funding constraints. Failing that, we need another ‘destructive’ storm of the order of that of October 1987, a natural dynamic event that breathed light and life into our previously neglected woodlands.

While Bluebells of course were the main course, there were substantial side portions of other woodland plants from Greater Stitchwort to Yellow Archangel, Wild Strawberry, Wood Speedwell and Bugle …

… along with the sub-shrub Butchers’-broom and swathes of Garlic Mustard in clearings and along tracksides, while on the higher drier ground Bracken was unfurling its aquiline fronds.

Our first walk, the recce, was in sunshine, although we found the ground conditions very difficult in parts of the wood, hence our decision with the groups to return along the Wivenhoe Trail and its views of the tidal River Colne, although the winter birds have now largely departed.

Insects on this occasion included the Beaky Hoverfly Rhingia campestris, the bug Harpocera thoracica, our first Scorpion-fly of the summer, and good numbers of Small and Green-veined White butterflies.

The second walk was pretty much a washout, although a Blackcap serenaded us at the start and in the interior of the wood we did find the uncommon Tree Slug, seemingly not recorded previously from the area.

Of course the Bluebells were immune to the rain, even if their scent was suppressed, and galls in the oaks likewise: there were redcurrant galls of the spring generation Spangle Gall-wasp in the flowers and large, spongy oak-apples formed by another tiny wasp Biorhiza pallida.

The final walk was again in glorious, warm sunshine. So uplifting! For us and for the wildlife too. Bird song was swelling, with a Garden Warbler being noteworthy, while butterflies included Peacock, Small Tortoiseshell and Orange-tips. Other insects included Crucifer Shield-bug, our first Dark Bush-cricket nymph of the summer and a mating pair of caddis-flies a surprising distance from water.

In the Lower Lodge grassland, Common Stork’s-bill was in good flower and on the King George Field, the pros and cons of ‘No Mow Grassland’ were amply demonstrated, with lots of Bulbous Buttercups and other species in the longer grass, but masses of Daisies, each flowerhead a lifeline for insects, on the mown bits. Everything in moderation is the best approach.

And as always, some surprises. A fungus looked familiar as the Jelly Ear, but we are used to seeing it on its main host tree Elder; this was on Sycamore, but reference to the books indicated that this and other broad-leaved trees can be used by the fungus.

Even more interesting, and potentially worrying, was the gall that Jude spotted on Sweet Chestnut leaves and buds. We had never seen it before although it was then found on quite a number of trees. It turned out to be galls of the Asian Chestnut Gall-wasp Dryocosmus kuriphilus. Seems this gall was first found in Britain in Kent in 2015, and has spread especially around London since then, although the latest map shows only one Essex locality, close to the M25. It is of concern to those who grow Sweet Chestnut for timber or chestnuts as it can be rather destructive, although help is at hand – a specific parasite of the gall wasp has been discovered, evaluated and risk-assessed, and is already being released in some places to control the new incipient ‘pest’.

Always something special and interesting to find!

 

 

 

 

#WildEssexWalks: Cockaynes Reserve at the height of Spring

As is now traditional we headed off to Cockaynes Reserve for one of our main springtime walks, although the cool weather initially made it feel almost wintry. Fortunately as the morning progressed, and contrary to forecasts, the sun did come out, and sheltered from the breeze it even felt quite warm, a rather unusual occurrence in the unsettled early part of this year.

But whatever the temperature  there is no mistaking the fact that the hands of the seasonal clock are turning. Walking up Ballast Quay Lane, the hedges and verges were filled with flower and fragrance, with Cow Parsley and Hawthorn scent combining in Chris’ personal Maytime Proustian madeleine, taking him back to the days of innocence, cycling the byways of the Yorkshire Wolds as a lad…

Add to that the blue of Evergreen Alkanet, the white flowers and garlic aroma arising from both Garlic Mustard and Three-cornered Leek, yellow Greater Celandine, and the purple (occasionally white) flowers of Honesty, the latter attracting the attentions of a lovely male Brimstone for the back-markers at least.

And in a nod to the coming summer, White Bryony just coming into flower while stitching together the hedge with its telephone-cord tendrils:

At the top of the hill, splendid views over the Colne Estuary, Skylarks singing, and a meadow full of Bulbous Buttercups, interspersed with drier patches dominated by rusty-flowering Sheep’s Sorrel …

And then into Villa Wood along the newly refurbished path, to be enveloped by bird song – Chiffchaffs, Wrens, Blackbirds, Robins,  Blackcaps and a tantalisingly distant Nightingale – and the sound of a tinkling Sixpenny Brook, with a little Town-hall-clock and Opposite-leaved Golden-saxifrage still flowering.

The Redcurrants were in unripe fruit, Wood Anemones all-but-finished, Bluebells of course just reaching their peak on the drier slopes and  sprouting ferns in the damper spots.

Moving out into the open ground left behind after gravel extraction, a backward glance showed the beauty of the infinite spectrum of greens shown by newly emerged leaves, a sight equalled by the sound of a much nearer Nightingale in full rhapsody, and displaying Buzzards overhead:

The bare sandy areas hosted a basking Peacock, with flowering Blinks, Changing Forget-me-not and Thyme-leaved Speedwell, and just a few Bunny Bees moving around their active colony (it had been a very cold, almost frosty night preceding, so the lack of action was not surprising).

In the heathy areas, both Gorse and Broom in flower were attracting bumblebees, along with Small Gorse Mining-bees, and held numerous singing male Whitethroats, while the Crab Apple on the corner of Cockaynes Wood was already well past its best, a sign of the largely frost-free winter.

And finally a few invertebrates, expertly spotted by Jude: a bagworm moth Psyche casta,  redcurrant galls in Oak flowers (the spring generation galls of the same tiny wasp that produces the more familiar spangle galls in autumn), Brown-tail Moth caterpillars sunning themselves on their web with impunity (protected from most bird predation by their irritant hairs), a few hoverflies and tiger-craneflies, and a grass bug Stenodema calcarata.

As usual, all kinds of everything to suit all tastes, and wrapped up very well with a pint in the Greyhound garden, sitting in the sun, with a Red Kite low overhead. What could be better? Thanks to all who came along and helped make it such a good morning, particularly Peter Hill who was able to explain some of the management work of the Cockaynes Wood Trust (and perhaps encourage some more volunteers to the much needed management tasks).

#WildEssexWalks: Signs of Spring around Alresford

Spring was certainly in the air for our latest WildEssex walk… but so was quite a lot of rain and drizzle: April showers two weeks early…!  We began at Alresford Old Church, the ruins lit up with transient sunlight and as impressive as ever.

The churchyard is one of the best in this area for the richness of its flora, with Common Dog-violet and both Red and White Dead-nettle flowering, a swathe of Wild Daffodils (or a close approximation thereof) and the delightful citrussy-mint aroma from Lesser Calamint leaves.

While the rest of us were looking at flowers, Jude was finding insects , including a 10-spot Ladybird and (best of all) a bagworm nestling within a gravestone inscription. Bagworms are very unmothy moths, and always interesting (see here for a previous blog about them), but this one wasn’t one of the usual Virgin Bagworms. For a start its bag was much larger than that species, some 8mm long with a distinct ridge running lengthwise, and probably of one of the three Dahlica species, all of which are pretty uncommon. And what’s more this had a larviform flightless female just emerged from her pupa, and it seems about to start egg-laying back into the bag!

Heading down to the Sixpenny Brook, the first of several Chiffchaffs was singing, signs of a very recent arrival perhaps, rather than over-winterers coming into song. Gorse was in full bloom and, in the sun, starting to scent the air with coconut, and attracting bees and hoverflies. Blackthorn too looked stunning, some bushes in bud while others were fully open.

Onto Cutthroat Lane, we passed a magnificent bush of Butchers’-broom, still showing a few flowers, each a subtle gem, and acid-green patches of Early Meadow-grass, a recent arrival here from more southerly heartlands:

Then down the edge of Grange Wood, with magnificent oak pollards and coppice stools on the woodbank, standing amidst the Lesser Celandines and the first few Greater Stitchwort flowers…

… while the Bluebells that will be so glorious in four weeks were just bursting, along with (outside the bounds of the ancient wood) Three-cornered Leeks.

And so we found ourselves on the shoreline, with many of the estuarine winter birds still here, including hundreds of Black-tailed Godwits, a hundred or so burbling Brent Geese and about 40 Avocets – the three birds for which the Colne is justifiably renowned and specially protected.

Sadly no one was with us to see our final, bizarre sight of the walk as we headed back home. There in a puddle on the top of the sea wall was a Common Lizard, almost covered by water, and doing a passable impression of an overactive newt! Eventually we managed to persuade it from its bath and released it into the long grass safe from feet and dogs.
