Is Brexit the path to sustainable farming?


However one feels about Brexit and its effects, one certainty is that farming and farmland, as we have known it during our EU membership, will change. The Agriculture Act 2020 was enacted in November and with it began a seven-year transition in which English farmers will adapt to a new financial support system to replace the Common Agricultural Polcy (CAP). 

The CAP has many criticisms and I doubt many wildlife conservationists will mourn its end. Under the scheme, farmers receive a Basic Payment subsidy based on the size of their farmed land. The intention is to guarantee minimum levels of production so that EU citizens have enough food to eat, and to ensure a fair standard of living for those dependent on the agriculture sector. The older EU states receive a larger payment per hectare than the others and France, Germany and Spain are considered to be the greatest beneficiaries of the scheme, which amounts to nearly €60 billion annually.

The policy has been accused of ignoring the rules of supply and demand, favouring larger farms and industry giants. It has promoted overproduction of food by member states, creating mountains of surplus food, which goes to waste or is transported to developing nations, thus undermining the livelihoods of local endemic farmers. It has also restricted development in poorer non-EU countries by imposing import tariffs on their agricultural products. It has also created bland farming landscapes as a result of of its broad-brush approach to farming strategies, with a narrow diversity of farming practises, grazing regimes and crop rotation. 

On 30th November Defra published a roadmap: Path to sustainable farming. This sets out the key aims of the seven-year transition. Instead of the flat-rate Basic Payment, farmers will be rewarded for engaging with farming practices that have environmental benefits. These will promote wildlife, reduce flooding, improve soil health, reduce soil erosion and include positive adaptations to climate change. This is summarised in a Government blog here

What might this mean for farming in the Greenhavens area? There is genuine hope that we will see more diversity in crop production and grazing regimes, better marginal environments around fields, the development of wildlife corridors, land being taken out of regular production, a reduction in the intensity of farming practices, creation of a greater mosaic of land uses, a reduction in the use of biocides, improvement in aquatic and semi-aquatic habitats, development of seasonal floodplains, more tree planting, greater public access onto enclosed land and a positive improvement in the visual amenity of farmland. The list is not exhaustive, but there is an opportunity to transform the current bland farmland aspect to one of a diversity of interconnecting habitats which will help British wildlife to recover from the damage it has suffered since the post-war intensification of farming.

There is, however, a recent cautionary tale from the Lake District that all landowners and regulating authorities should keep at the front of their minds, and that is the rush to indiscriminately plant trees in order to achieve targets, such as those set by carbon sequestration to reduce the impacts of climate change and the Forestry Commission's committment to plant 30k hectares of trees every year until 2025.

With a decline in public services since 2010, environmental regulators have fewer staff on the ground and there has consequently been an erosion in local knowledge, with a greater reliance on computer models and desk-top studies. The Forestry Commission (FC) is one such authority which inadvertently became a victim of this.

The FC is the responsible authority overseeing afforestation by private landowners. The owners of Berrier End Farm near Penrith in Cumbria, an area on the edge of the Lake District National Park, asked for permission to create a commercial conifer plantation. 

The FC required them to submit an Environmental Impact Assessment, a breeding bird survey and archaeological assessment before granting permission. A GIS mapping system was used to identify any priority habitats on the land proposed for afforestation, but because Berrier End Farm has no formal designation or protection for wildlife, and because no field surveys were carried out, its rich wildlife habitats with peat bog and transitional mires with a wealth of rare plant communities was not identified. 

Once permission was granted, responsibility was passed from FC to the Countryside Stewardship and the Rural Payments Agency for grant payments. It wasn't until areas of deep peat were ploughed, destroying important wildlife areas, that a local botanist raised the alarm with FC. But by then it was too late.

The FC genuinely cares about wildlife and it has been embarrassed by this episode in large part because it is struggling to fulfil its priorities as a result of Governmental resource cuts. 

A vibrant community of wildlife enthusiasts will need to engage with the new farming regime if similar unintended consequences are to be avoided - and this applies to the Greenhavens area as much as anywhere else. Let us hope then that the new Agriculture Act 2020 helps to improve all apsects of our farmed landscapes without harming wildlife and habitats and that 2021 will be the beginning of positive change.

Hibernating wildlife – dormancy as a winter survival strategy

Hibernating wildlife – dormancy as a winter survival strategy

Did you know that the Dormouse is named after the French word meaning 'to sleep': dormir? It's one of quite a few British wildlife species which have adapted to winter by dodging it entirely.

We're halfway through the darkest time of year and have arrived at that brief moment of suspended animation, the Winter Solstice, when the days neither shorten nor lengthen. The world seems to be in a state of dormancy. For much of our wildlife the toughest time still lies ahead. Food is in short supply; life is full of challenges. Species that aren't able to migrate need to tough it out, but some species have adapted to conserve their energy by hibernating.

Much energy is saved by entering a state of torpor – the result of reducing heart rate, breathing, metabolism and body temperature. The depth of torpor varies between species and it is punctuated with periods of activity within their hibernaculum, a place of hibernation and relative safety, protected from the extremes of temperature, humidity and wind.

Hibernating animals still burn energy, but at a much reduced rate. They need to ensure their fat reserves will sustain them throughout the winter. Like migrating species, hibernating creatures feast on the autumn harvest in order to maximise their body fat before entering the hibernaculum.

Who hibernates?

Insects

Most butterflies spend the winter as eggs (ova), larvae or pupae, but some species hibernate as adults and emerge on warm winter days and at the start of spring as the day-length increases. These include the Brimstone and Red Admiral, which hibernate deep within vegetation, and the Peacock and Small Tortoiseshell, which seem to prefer structures such as unheated buildings or rabbit holes, providing the light, temperature, humidity and ventilation are stable. Rabbit warrens are excellent places to search for emerging butterflies on warm, sunny spring days.

Many moth species also hibernate as adults, including the stunning leaf-like Herald and the Bloxworth Snout, a recent UK colonist which is tolerant of the cold and usually only enters a light hibernation.

If you have ever noticed swarms of ladybirds in late-autumn around your windows and doors, these are likely to be the Harlequin Ladybird – an invasive Asian species released in Europe to control aphids. Hibernating around fenestration protects them from frosts and moisture.

Some fly species also hibernate and the one most commonly encountered is the Cluster Fly, a parasite of earthworms, which likes to hibernate in roofspaces and false ceilings.

Reptiles and Amphibians

All British reptiles and amphibians hibernate, although my pond often has active frogs around it deep into mild winters. Palmate newts overwinter in the damp ground beneath logs and stones, where they are protected from predators and frosts. Reptiles such as snakes and lizards choose dry hibernacula such as old burrows and compost heaps.

Mammals

The only geniune mammalian hibernators are hedgehogs, dormice and bats, but most other species including rodents and badgers become less active. Bats are often found in similar places to butterflies and moths. Hedgehogs make a hibernaculum from dead vegetation and emerge only to add extra insulation if the temperature drops too low.

Gardening for hibernating wildlife – how you can help wildlife in winter

Not tidying parts of your garden will help to provide space for hibernating wildlife amongst long grass and vegetation. Creating log-piles, a compost heap or making a bug hotel will help insects, amphibians, reptiles and mammals overwinter. Remember though to check bonfires before they are lit for hedgehogs and other species.

You might find a butterfly or moth inside your home which has been woken by the central heating. By holding them gently it is fine to place them in an outbuilding or in a hedge that can be safely exited when spring arrives.

The effects of climate change can confuse species, especially if warmer winter temperatures cause them to emerge before there are sufficient food or nectar sources to sustain them. This can be especially harmful to bees, which are among the earliest hibernators to emerge on warm winter days, when there are few or no natural nectar sources. Growing winter-flowering plants and shrubs can help them, as well as placing food out for birds and mammals.

Bloxworth Snout (Hypena obsitalis) moths only enter a light state of hbernation and are more tolerant of low temperatures than many other species

Additional photos and information to the Greenhavens article 'Admiring the Beeches at Duke's Walk in Seaford'.

There follows some additional information and photographs to accompany an article on the Greenhavens Network blog

Many of the larger trees along Duke's Walk, which runs along the foot of Rookery Hill at Bishopstone, have buttressed bases to the trunks and exposed roots spreading across the path, some covered by a filigree of small ivy growth, others with large corded vines reaching up into the canopy. Lichens glow in the murky light. 

I have tried measuring the girth of the largest trees, but it is a two- or three-person job. They straddle the flint wall in places, have a halo of bramble and overlook the water-filled channel. Not an ideal lone-working environment! The girth of the trees has swelled not only beyond the collapsing flint wall but also across the lines of barbed wire stock fence built to replace the wall. Some of the trees are slowly absorbing the wire.

Many of the Duke's Walk beeches have buttressed roots and a filigree of ivy growing up the trunks.

The beech trees have outlived a broken, collapsing flint wall, and the wire livestock fence that replaced the wall. Some of the beeches are absorbing the barbed wire into their boles.

Sixty year-old graffiti

One of the most striking features of the elephantine beech trees is the bark, which is smooth like a living vellum. This feature inspired the modernist artist Paul Nash to depict them in lithe, human form in some of his works. The Duke's beeches are tatooed with the work of other artists: young lovers with pen-knives, keen to share their ardour with all who pass. The oldest graffiti has swelled with the growing trees. The earliest discernable date I found is 1961, but other carvings seem older than this. When I first encountered the beeches about 35 or 40 years ago I was told by my friend's father, who had brought us there, that his initials (BG!) were somewhere on one of the trees. The tradition has been maintained through the years: 1975, 1996, 2018. To some this is vandalism; to others an artistic expression of love.

The Holly bears the Crown: the seasonal significance of Holly 2/2

 The Holly bears the Crown: the seasonal significance of Holly 2/2

Part 2 of 2: Ecology

In the first part of this seasonal study, we established that Holly and Ivy are symbolic plants associated with the Winter Solstice, Yuletide and Christmas traditions. Ivy was used to symbolise femininity; Holly, masculinity. The name Holly is suggested by some to be a corruption of the word 'holy'. 

In folklore, Holly was apparently allowed to grow tall above the hedgeline in order to impede witches as they flew above them. For centuries at Christmas, garlands of holly and ivy have been collected to decorate the outside and inside of peoples' homes, often with ivy outside and holly within (Deck the Halls), but it was considered unlucky to do so before Christmas Eve, perhaps because cutting the boughs would allow witches to move more freely. Records describing the seasonal cutting of holly boughs date as far back as the 15th Century in the reign of Henry VI.

Holly was historically a source of winter livestock fodder at a time when greenery was otherwise limited or absent. It is for this reason that holly was grown for pollarding*  and these are reflected in British place names and peoples' names, such as Hollywood, Holt, Holm and, most importantly, Hollins. There are often no holly trees remaining at these places, but stands remain around the New Forest, Dorset, and perhaps most impressively at Staverton Thicks in Suffolk and the Stiperstones in Shropshire. 

I am not aware of many examples locally within the Greenhavens area, but there is an impressive Veteran Holly in the churchyard at Barcombe** and there is a area of dense Holly growth with the occasional mature tree at the rear of the old Union Workhouse at Newhaven, now part of the Meeching Down Local Nature Reserve in Newhaven. Is there any historical relation between the trees and the former workhouse? The land was part of the Union Workhouse from around 1835 and this is why locals still call Meeching Down 'The Union Field'.

Holly growing at The Union (Meeching Down Local Nature Reserve, Newhaven)

Holly is an impressive member of Britain's native flora. It was one of the earliest trees to colonise the land after the last ice age when a land bridge still existed with continental Europe. It grows in a range of soil types at at a range of altitudes. It is susceptible to extremes of temperature and moisture (i.e. drought and waterlogging), but it is otherwise tolerant of exposure to wind, salt, shade, browsing by animals, air pollution and pollarding. 

Holly berries are toxic to humans, but a few can be taken as a purgative. Birds such as Mistle Thrushes Turdus viscivorus (a folk-name is 'hollin cock') and Robins Erithacus rubecula are so fond of them that they will defend individual bushes as a food resource during cold seasons. For a species which colonised Britain so early, its tough adaptations are so successful at deterring invertebrate larvae that only a few species are associated with it, the most conspicuous being the leaf-mining fly Phytomyza ilicis, which causes a distinctive yellow and red blotch-mine on its tough leaves. The caterpillar of the Holly Blue butterfly Celastrina argiolus feeds on the developing berries on female trees. This butterfly has two broods each year and the second brood eggs are laid on ivy, where the caterpillars feed on the flowers. The Holly Tortrix moth Rhopobota neavana also feeds as a caterpillar on silk-spun leaves and flowers of Holly and other fruit trees.

One fascinating characteristic about Holly is that its leaves above the browseline are less spiny or spine-free. Growing spines on its leaves involves additional energy input, so it is possible that it evolved either to lose its spines above the level reached by deer or it evolved to grow spines below a certain level in response to browsing by deer. The bitter bark can be boiled to produce a sticky substance called birdlime, which was used historically to capture small birds, a link back to the Christmas carols.

And the first tree in the greenwood, it was the Holly (the Sans Day Carol). 

Happy Christmas everyone and may the yuletide log burn bright and warm in your hearths!

* Pollarding is a form of tree management similar to coppicing in which growth is cut back periodically above the height of browsing animals such as deer. Trees are pollarded to provide winter fodder for livestock or wood products for basket-making and other traditional crafts.

The Holly bears the Crown: the seasonal significance of Holly 1/2

The Holly bears the Crown: the seasonal significance of Holly 1/2



Part 1 of 2: Culture

Do you have a favourite Christmas Carol? At this time of year I dig out a favourite Christmas album called A Tapestry of Carols, performed by Maddy Prior and The Carnival Band. It is one of the most authentic collections of seasonal folk-carols I know of. Two favourite songs both have Holly Ilex aquifolium as their central theme: The Sans Day Carol and The Holly and the Ivy. They are examples of quite a few seasonal songs which use these evergreen plants as pagan and religious symbols.

The Holly and the Ivy was always a childhood favourite of mine, even if I didn't appreciate at the time how steeped it is in both Pagan and Christian tradition. 

The first and last of the six stanzas are repeated:

The holly and the ivy / Now are both full grown / 
Of all the trees that are in the wood / The holly bears the crown.

The lines are interpreted to mean that the Holly and Ivy Hedera helix, being evergreen, are the most prominent at around Midwinter, but that the holly and its value at this time is worthy of divine comparison, the crown being Christ's Crown of Thorns. The Holly is King of the Wood at Midwinter.

The middle four stanzas of the song compare the divine attributes of the holly and ivy with Jesus and the Virgin Mary: flower, berry, prickle and bark, which respectively represent purity, blood, the Crown of Thorns and the drink of wine mixed with gall, a bitter herb which Jesus was offered but refused as he was led to his crucifixion (Matthew 27:34).

The chorus contains some interesting historical and natural references:

O, the rising of the sun / The running of the deer / The playing of the merry groan / Sweet singing in the choir.

The rising of the sun refers to the rebirth and reappearance of the sun after Midwinter and heralds the new year.

The running of the deer refers to the tradition of hunting on the day following the Winter Solstice. Holly is a winter browsing plant for deer and, historically, people would certainly have felt the need to defend their 'hollins' from them. It might be an activity being described in this line of the verse. Thankfully, this hunt which at the height of its popularity evolved into the indiscriminate killing of any bird that could be taken, including songbirds, and which were then baked in pies, has been replaced by Christmas Bird Races, in which groups of enthusiasts travel across wide areas and compete to spot as many bird species as they can find. The Isle of Man's Christmas Bird Race might also be their modern version of the Manx 'wren hunt' - another cruel tradition.

The playing of the merry groan refers to a stringed 'renaissance instrument' that would have accompanied carol singers. Maddy Prior's rendition, as with most modern versions, replaces 'groan' with 'organ' (I'm not sure if the anagram of organ/groan is accidental or intentional), but it feels more clumsy than the original and doesn't rhyme or fit the metre. The original lyrics included 'groan' in the published broadside*.

Sweet singing in the choir. The pre-modern English word for choir would apparently have been pronounced 'keer', which of course rhymes with 'deer'. Who doesn't like getting together at this darkest time of year with like-minded souls for a satisfying sing-along? Wassail!

* A broadside was a large format print designed to be pasted to a wall and used for public notices amongst other things and was popular in the 18th and 19th Centuries. The first printed version of The Holly and the Ivy was printed on a broadside around 1711, although the exact date can only be estimated. Limited numbers of broadsides were also produced for things such as public executions!

Get into the woods! No matter what you expect to find there – go and see what you can find*

 *from Sequoia Sonnets, 1919


I am no arboriculturalist, nor a botanist, not really a nemophile (visits to woods are a special occasion when one lives on the eastern Sussex Downs), but I might be a dendrophile. I have for many years appreciated trees and made pilgrimages to visit special individuals. I have been known to involuntarily say "Hello!" to certain astonishing individuals. It sometimes feels rude not to when invading their space. During the past couple of years I have started measuring their girth, observing their characteristics, noting ancient features, lichen and moss communities and cuckoo tree growth, along with all the usual stuff like what they are, where, when. Why? I'm a dendrophile! But also because there are lots of special trees out there that are not really taken much notice of. A special tree deserves to be recorded, even if this risks stealing something of its mystique, as John Fowles might accuse one of in his The Tree diatribe (a memoir that is worth reading if only for his description of an encounter with Wistman's Wood on Dartmoor: it's "floor like a tilted emerald sea...".

Trees deserve to be recorded because they tend to be there - and then not. It's the not being there which often kindles the strongest emotions, and by that stage it's too late. So, yes, recording a tree sort of trespasses upon its mystique, but perhaps only for the recorder and administrator, the botanist and arboriculturalist, whom arguably experience this as an occupational hazard anyway. By recognising its ancient features or opening a door for it into the Ancient Tree Inventory (ATI), it might be protected for lots of  other people to encounter who might otherwise not have enjoyed the opportunity. I wrote might be protected because there are plenty of examples where special trees, whether Notable, Veteran or Ancient, trees with TPOs, trees with a community awareness or even a community of defenders are ripped from us, usually by developers who see an obstacle and not a landscape feature. Two recent examples are the Penllergaer Giant Redwood in Swansea and the Cubbington Pear in Warwickshire (see herehere, here and here). That final news story saddens me such a lot because it demonstrates how people look at a tree and see only the above-ground bit and fail to recognise the mycorrhizal networks, the community of dependent species of bacteria, fungi, lichens, mosses, vascular plants, invertebrates, birds, mammals and everything else that an established tree harbours. Scions and sports need to establish themselves before they even approach the value in life that the Cubbington Pear supported. Grrr. But at least a measured, verified tree is known.

The ATI lists only two special trees in Newhaven and one of these is a 'lost' tree: a magnificent Huntingdon Elm Ulmus x hollandica, felled from its place at Grays School on Western Road, apparently, due to Dutch Elm Disease shortly before the vacant school was redeveloped into the modern houses which now stand there. I mourned the loss of this tree, which was mature when I attended Grays School between 1975-78. The other is an unspecified elm growing on private land in the 'old town' area, near Church Hill. I felt that two trees, even in a relatively tree-less area of the South Downs, was not representative enough of what is an historic town with historic places. Surely there must be more? This question has inspired me to establish whether there are more out there. 

Here are some of the special trees I have since found around Newhaven and the surrounding district, some of which I hope will be accepted into the ATI...

Beeches Fagus sylvatica, Duke's Walk, Bishopstone

A row of six healthy, mature trees interspersed with diseased Wych Elm Ulmus glabra, possibly planted c.mid-18th C by the Duke of Newcastle (or descendants of the originals). Not yet measured (I need a helper or two).

Late April field notes



Moon near Venus
Mackerel sky
Thank goodness that the weather's been so nice during the Covid-19 lockdown. Things could have been much less relaxed. This is the first year I remember in which the first four weeks of the transect-walking season (otherwise known as the one hour daily exercise period) have been 100% sunshine. The perfect weather we've enjoyed since around mid-March is appreciated all the more because of the fresh memory of the miserable, wet winter we endured and because of the eventual break in the weather that we all know would eventually come; just as the beauty of the night sky is appreciated more by the memory of an overcast sky.

Knowing that the good weather was due to break on Monday night, I made a point of enjoying the last good evening for a while by taking a late walk when I was hopeful I would have the Bishopstone downs to myself. I did. The previous evening the sky was clear and the crescent moon, three days old, was near Venus. It was a stunning sight; one I could never tire of. Monday evening had a mackerel sky which faded to salmon pink as the sun sank; the Moon and Venus flashed in and out through the gaps. The air was still and the scent of flowers hung in the air, thick and sweet. I think people experience smells slightly differently from each other, in the same way we seem to see colours in slightly different hues. With cow parsley I sense a slight camphor odour, not as strongly as I do with Alexanders earlier in the season, but it is there faintly. As I walked along the silent paths in the gloaming, alternate smells of camphor and sickly sweet hawthorn overwhelmed the senses.

We walked up to the top of Mount Pleasant and via Norton Hill and Rookery Hill to the road at Bishopstone. I hoped to see the barn owl or a tawny owl, but the silhouettes were mostly crows and rooks. A cuckoo flashed out of the woodland edge at the top of Bishopstone Wood, my first of the season. I had heard it call a few minutes before and the dogs must have flashed it up. A little further on I saw what I thought might be a roe deer – not the first I have seen in the area – but it was too dim to make an ID with any degree of confidence. Whatever is was disappeared along a well-worn track and into the trees. I'll check it for droppings when I'm next over there in the daylight.

In the gloaming I'm struck by how things which are pale in colour tend to glow. Umbellifers and hawthorn blossom framed the fields and, amongst the grass, thousands of dandelion clocks lit up dimly like tiny lamps. I wouldn't have appreciated their number during the daylight and I love it that they became more obvious in the in-between light of the dusk. I learnt the other day that our word dandelion is taken from the French dents de lion, or lion's teeth, a description of the leaves. I wonder if the Normans brought the name over with them? 

Sunday afternoon allowed a long, leisurely ramble over the downs between South Heighton and Beddingham. The lockdown doesn't allow such long walks as I'd like, but I was able to make the most of the sun and light breeze. I climbed the hill above Page's Barn with the hope of finding some oak eggar caterpillars on the bramble between the path and fenceline, but none were seen. I counted 64 along the same stretch in 2014, but annual searches since have turned up nothing, which is disappointing. I did see my first painted lady of the season and possibly also my first small heath, but this disppeared before I could tell for certain. A little further along at Snap Hill I saw another red kite, bringing my 2020 tally to five – all in the Newhaven area.

The garden continues to delight. I noticed a number of yellow-backed clothes moth (Monopis obviella), carrion moth (Monopis weaverella), white-shouldered house-moth (Endrosis sarcitrella) and narrow-winged grey (Eudonia angustea) flying around the compost heap in the still air on Monday evening. I've found the Monopis species and sarcitrella to be associated with dried grass clippings in the past. More firsts have turned up in the moth trap: I have now recorded eleven species this month which I had never previously seen in April and newly-emergent species are appearing for the first time this year most nights now. The good weather has undoubtedly brought forward many emergence times, but the general trend of climate change must also be at play.

With a couple of days and nights still left in the month it is clear that this April has been one of the best for butterflies and moths. I've recorded 88 species and 1011 individuals so far. Only April 2014 has been better. Many species have been above both my five year and ten year average. I'll try and find time to write it up in more detail after the month end.

The Striped Summer Chafer (Rhizotrogus aestivus) - first UK record?

Rhizotrogus aestivus - recorded first in Newhaven?


Things at home have become very interesting. It seems that I recorded a beetle that is new to the UK – or perhaps not. It is Rhizotrogus aestivus or the June Chafer. I've found it in my moth trap on three occasions recently: the 20th, 25th and 27th. I'm ashamed to admit that I've been wrongly assuming it was summer chafer (Amphimallon solstitiale) for at least two years, possibly longer, and not taking that much notice of it. A friend from the Friends of Castle Hill LNR photographed one at Fort Road on 30th April last year and, when asked if I knew what it was, I wrongly said it was summer chafer again. I didn't photograph any of those found in my moth trap. It was only after the first of this year's turned up that I began to question myself. The summer chafer flies from July, which made it far too early. This was the individual I described in a recent blog post that escaped. It was only when the second individual turned up on 25th that I was able to take a closer look and realise that it was Rhizotrogus aestivus.

A quick search of the NBN Atlas suggested there were no UK records and I began to feel some excitement. I wrote to Bob Foreman at the Sussex Biodiversity Record Centre, who confirmed there are no Sussex records. Bob wrote to Peter Hodge, who was sceptical (quite right too). I wrote to Graeme Lyons, who forwarded the details to Darren Mann, the national specialist. This was getting quite serious. Darren advised that he would need to see a male to confirm the ID, but he seemed confident from the photo that it was the right ID and a beetle that is new to the UK fauna. The trouble is that I had released the chafer after making the ID [yes, I know, I'm a rubbish entomologist], so I had to wait and see if another turned up, which it did on 27th. I'm now waiting for further instruction. 

Another exciting aspect of this discovery is that, assuming it is accepted as correct, when the record makes its way into the national coleopterists' consciousness, further records could be turned up and people can get out to search for it. I find it fascinating though that new records often turn up at ports such as Newhaven. The Mediterranean Oil Beetle is another local example, along with amongst other speceis the elegant topshell Trochoidea elegans and the wasp spider Argiope bruennichi.

As a postscript, because I didn't do a proper job of recording the chafer in the past, the first sighting that we can make a proper record from is the one that my friend Sue photographed on 30th April last year. Hopefully I can include my name in the record as the determiner, but it is a cautionary tale and a lesson learned.

I'll add further details as things develop.

Sociable Distance and other inspirations

Still the perfect weather helps to relieve the stresses of the lockdown confinement, slightly warmer and less breezy today with a lighter wind from the south instead of the easterly which has been dominating in recent weeks like a hair-dryer set to cool. Interestingly, the easterly breeze we often get, which can last for several days unabated, a bit like the Mistral, always seems to blow at a steady pace and without the blustery nature of the prevailing south-westerlies. This effect is especially felt along the ridge at the top of Mount Pleasant overlooking the waterworks at Poverty Bottom.

Red Admiral and Holly Blue sightings have been growing in number at home in the garden. Large Whites blouse their way across from garden to garden and Small Whites flutter through in decent numbers. Brimstones and Small Tortoiseshells seem scarce, although most of my Brimstones are usually seen abroad north of the downs along Wealden tracks that I'm not visiting so often this year.

The first, anticipated, sight of Cetonia aurata (Rose Chafer) has now been made in the garden, the metallic green elytra being quite conspicuous on the white Choisya blossoms. There were two today on it. It was a treat to see one a few years ago (perhaps less so for gardeners), but they seem to have established themselves so well in our area in recent years that they are a daily occurrence these days. The Choisya itself has spread a fair amount since last year when I thought it was a little stunted. The scent of the flowers is delicious and fills the garden, having taken over from the Daphne as if they had rehearsed it. Amanda wants to cut it back. Not on my watch.

I made a couple of bee hotels from baked bean tins for the garden before breakfast. Funny how one expects an instant uptake by bees – I've been hovering expectantly at times throughout the day without noticing any interest. Jack-by-the-hedge was found growing by the pond; I think this is a first record for the garden. Ash leaves are now unfurling on the big tree, some way behind in progress from the expanding palms of sycamore. The ash has a lot of trunks, all with a filigree of climbing ivy. The tree must have been coppiced on several occasions before being left long enough to outgrow the gardener's saw. My moth trap lights it up at night like a feature tree.

Recent nights with the moth trap have seen the first appearance of Green Carpet and only my second ever April record of Coxcomb Prominent, which plays dead in the hand like a flake of wood. Brimstone Moth, Muslin, Angle Shades and Shuttle-shaped Dart are becoming slightly more numerous; Brindled Beauty and the Orthosias are dwindling slowly, but after an above-average season. Overall numbers are quite low, but should begin increasing again soon.


Coxcomb Prominent (Ptilodon capucina)
I did my transect walk at lunchtime today, with the dogs. I had high hopes, which came to little. Of the 52 butterflies seen, 39 were Small White which were loitering with intent around the oilseed rape, with a nice male Orange-tip, two Large Whites, seven Peacock, only a single Small Tortoiseshell,and two Nettle-tap moths making up the numbers on what was otherwise a quiet and disappointing day. The day had a siesta feel to it in the sun and slack winds; perhaps I should do the walk earlier or later?

The daily walk is a valuable distraction and I'd struggle through the lock-down without it, but each day I look across to Castle Hill LNR on the far side of the river valley and miss it more. I've been thinking of different ruses to help justify visiting and I think I've come up with a solution: a grass-roots walking movement designed to encourage people out for guided daily exercise (walks though – none of that pseudo-army boot camp business) at local nature reserves for one hour each day, walking two or more metres apart from the next person. Participants could bring two metre sticks with them, with or without sharpened points, to help keep other folk at bay. I have even come up with a snazzy name for it: Sociable Distance. The name might be better than the idea itself. Potential sticking points include:
  • engaging in an activity which might not fall within the spirit of the lock-down restrictions;
  • persuading Lewes District Council to consent to the use of the open space for an activity which might not fall within the spirit of the lock-down restrictions;
  • persuading my employer to agree to the time off work.
  • There are probably more sticking point to discover during this uniquely mendicant time.
Having the idea in the first place suggested to me that even I am beginning to crave social interaction with other humans. The spring moth lull must be getting to me.

Another lockdown-inspired idea occurred to me shortly afterwards, which would involve using pegs and string to mark out 2m squares at open spaces for people to enjoy wildlife whilst social distancing. The World Between us doesn't sound as snappy a title as Sociable Distance, so more work might be required and I am open to suggestions – and any suggestions received would demonstrate that I'm not the only person who reads this blog! A sticking point: would the Council agree to encourage people out to its nature reserves at the moment? I'm not sure I would.

More lockdown delights

It's incredible how the natural world is just carrying on amidst all this Covid-19 lockdown business. A swarm of flies has been ignoring the two metre social distancing thingy, dancing around in the air above our rosemary in the back garden. There seemed to be more there today, so word is obviously getting around. I think they're lesser house flies, which must mean they are preparing an onslaught on the District's poultry houses.

Moths seem to be in their Spring lull since the Orthosias declined to a handful a night, but we did get a nice Powdered Quaker in the trap last night and I found a bonus Angle Shades on a nettle during my morning stroll around the garden, mug of tea in hand. I also found in the trap this morning a nice little chafer which I think was a summer chafer, but it seems far too early for this (it is named solstitiale after all) and was perhaps less hairy than the images in my book. It might be something else. It fell on the grass and melted away before I could photograph it, so I will have to hope for another before attempting an ID. Still no Rose Chafers seen in the garden, despite the Choisya being in near full bloom. I had hoped they might appear slightly earlier due to the good weather.

We took a lunchtime walk. The stockpiled brash on Norton Hill, where we heard a hedgehog at dusk a couple of days ago, today had a swarm of bees enjoying the shelter it afforded from the strong easterly breeze. They were too busy and quick to be identified, but I think they were a Lasioglossum species of some sort. To the south we looked longingly at Castle Hill LNR, which is mostly out of bounds during the present lockdown.

The butterfly season appears suddenly to have moved on and looks promising for the next six weeks or so, providing the weather stays good. We saw our first Small Copper yesterday; today there was a fair amount of activity in the sheltered places. We saw Large Whites (2), Small Whites (9), Red Admirals (4), Small Tortoiseshells (2), Commas (2), a Holly Blue, some Nettle-tap moths which were fizzing around the herbage, quite a few Dock Bugs (30), Gooden's Nomad Bee and our first dragonfly of the season: a female Large Red Damselfly, which I managed to take a shaky snap of. 

Swallows seem to be arriving in greater numbers. We've been seeing odd ones for about a month, but a small group of five were swooping around the hedge line on our way back home. Plenty of humans were out and about too – far more than usual since the lockdown was imposed but, unlike the flies, they were at least maintaining an appropriate distance.
