Common pouchwort

5 March 2013.  This was a brimstone day (I saw a male butterfly of this species in our lane) with the temperature reaching 13.3 C. 

I am continually surprised at what goes unnoticed, by me at least.  In the afternoon, as it was sunny, I sat on my wooden seat and scoured the surface of Emthree with close focus binoculars and noticed what was obviously a small liverwort growing on the damp eastern face of of the rock at the southern end of Henry's grave (Henry was our Jack Russell terrier who died almost exactly 11 years ago).

Early March

1 March 2013 I was struck today by a comment in Grimaldi & Engel (2007) Why Descriptive Science Still Matters. Bioscience 57 (8) : “Even the most prosaic description is actually a highly selective account of features that are found to be significant in comparison with related things. As a result, there is no such thing as a perfectly complete description or a perfectly complete classification or organization system; as descriptions become more refined and thorough, so do the systems of organization.”

It seems I still have a long way to go with Emthree.

2 March 2013 I have set out two half watermelon skins on the north west and south west sides of the Green Sanctuary to see what happens to them. If full of water they will, of course, act like water bowl traps for insects. That might be quite interesting as they will, of course, retain some of the esters and other aromatic chemicals of the fruit.

The pendulous sedge Carex pendula in Medlar Wood has been eaten down by at least 50% by rabbits, but I am sure it will recover.

3 March 2013 The newly arrived chestnut round was scattered with tiny dark brown objects like spiky moles. Close examination showed these to be dead scales from the Lawson’s cypress hedge behind the metre.

The tiny heart-shaped dead and empty seed ponds of heath speedwell Veronica officinalis are a distinctive feature of the dry grass and the plant, as the Online Atlas of the British and Irish Flora points out, “grows on well-drained, often moderately acidic or leached soils, and in some grasslands is confined to raised ground or anthills”. Our plants do best on raised ground and anthills.

4 March 2013 I photographed to small holly discovered yesterday behind Midsummer Pond. It is decidedly yellowish green rather than the dark racing green of normal holly, so I shall have to watch it closely. A wire rabbit guard is called for.

It was a fine sunny day, the first I think with spring in the air. The birds were singing loudly and the grass had a flattened, dull, post-winter cast.

The leaf bud on a wild rose was swelling with joy above the winter thorns.

Early spring at last?

After the long cold and wet of the winter, the thermometer suddenly rose today reaching 11.9 C at the warmest.  The sun shone more often than it didn't and bird song was picking up.

The land is still saturated with water and there was much standing in Emthree, with the ponds and pools full and a long puddle on the path around The Waste.

The brightest thing visually was the bark of the birch tree, peeling in orange flakes to reveal the steely white beneath, small horizontal lenticils like subcutaneous worms circumnavigating the trunk and complex 3D black flecks and patterns.

Just behind the old log at the back of Midsummer Pond I noticed a line of some 13 ivy seedlings.

There must be some reason why they are disposed in such an orderly row, but I cannot think what it is.

A bit further away the pendulous sedge (Carex pendula) is starting to grow away after a strong assault by hungry rabbits, while the stinging nettles, despite the cold, have already started into growth.

January feather

A small, pure white downy feather on the grass by the eastern edge of The Square Metre. Such a delicate, out of place thing, unsullied by the muddy wet of winter. Wild rose leaves stay green all through the colder months. The blackbirds are singing loudly. Tiny midges float across my gaze, little disturbances in the atmosphere, little flying pieces of smoke.

2013-01-30 15.55.53

I have spotted a plant of wood avens or herb Bennet, Geum urbanum, in Medlar Wood, a new record for Emthree and the first new record for 2013. As the name implies, this is characteristically a woodland species, but comes up very frequently in gardens. The roots have a clove like taste and can be used to flavour food and drink.

Two bricks and a stone

Quite cold but beautifully sunny for most of the day making it feel almost like early spring. I kept to my promises to myself and took a second brick down to Emthree and have installed it , frog up, next to yesterday’s frog down example. I filled the sky-reflecting frog with local water and was quite surprised by the amount it held.

I think it is worthy of the Tate Gallery.

IMG_1140I also uncovered the Glen Lyon Stone. The lichen has gone, but otherwise in is, unsurprisingly, not visibly changed since its arrival in 2004.

The top picture shows how it was yesterday.  The second picture how it was today.  And the third picture how it was in July 2004.

New refugia & thistles

It has been a mild opening to the year, but is now turning colder – only 6.8 C on my midday visit. I have installed a pale orange chunk of split sweet chestnut (from the wood at the end of the garden) to where the first piece of wood, now long decayed, once lay. It was called ‘Gingerbread Refuge’ and I shall continue to use this name.

20130110 Metre chestnut refuge (2)Just outside the north west corner of Emthree I have replaced an old, black plastic plant tray with a reddish house brick, its frog (the indentation on one face), lain downwards. I might add another brick, face up, so that the frog acts as a tiny shallow scrape, though I will have to keep it topped up with water.

20130110 Metre brick

I noticed two kinds of thistle rosette. One, growing almost vertically on North Wall, has very weakly serrated leaves quite different from the marsh thistle towards the south east corner of Emthree whose leaves are deeply serrated and very prickly. Both will need watching as the season advances.

Autumn ruminations

Last night we had the first frost in the garden since early April and the hour went back this morning at 2 am, so suddenly the feeling is wintry rather than autumnal.  There are many colourful leaves on the ground.
20121028 Metre (12) And various fungi including the group of sulphur tuft, Hypholoma fasciculare, below, a species that was flourishing here last December.
20121028 Metre (6)
There is much activity too on the top of Butterfly Rock.  In this picture there are at least two kinds of lichen, and several mosses as well as evidence of perching birds and rabbits and ambitious tendrils of heath speedwell, Veronica officinalis, climbing up from below.
20121028 Metre (7) Late autumn tends to be a rather sad, dying time of the year and it is difficult for me not to reflect on the newly arrived ash die back disease, Chalara fraxinea.  There has been much talk about this in the media and most of the accounts I have heard are very unbalanced.  A better way of getting an understanding of the situation is by looking at the Forestry Commission's fact sheet on the issue:
http://www.forestry.gov.uk/chalara
The general story from the media is that nearly all the ash trees in Denmark have died, that a few cases have been found in Great Britain and that imports of ashes from nurseries abroad have been banned.
According to the FC the disease was first recorded in Poland in 1992 and infected trees have been found widely across Europe including six places in various parts of England and Scotland.  As it is a fungus presumably it spreads by spores that can travel in all sorts of ways.  The FC add that "It is believed to have entered Great Britain on plants for planting imported from nurseries in Continental Europe. However, now that we have found infected older trees in East Anglia with no apparent connection with nursery stock, we are also investigating the possibility that it might have entered Britain by natural means. These include being carried on the wind or on birds coming across the North Sea, or on items such as footwear, clothing or vehicles of people who had been in infected sites in Continental Europe."  (I wonder how they are going to investigate these possibilities).
The banning of imports might, I suppose, slow the spread of the disease, but it looks rather like shutting the stable door after the horse has gone.  Most of us remember how fast the horse chestnut leaf miner moth spread: stopping imports of its host would have made little difference.
With Dutch elm disease, the various afflictions of oak, phytophthera on sweet chestnut and other species I sometime wonder if this might be the way nature operates, killing whole swathes of trees from time to time and opening up forests for other flora and fauna.  Often a few individuals of the species attacked seem to survive, like post-myxomatosis rabbits, to repopulate the old habitat which, by then, may be relatively free of their pests and diseases since these have had little or nothing on which to subsist.
Anyway, my ash tree in Emthree (naturally self-sown) seems to be doing fine and the slight curling of some leaves is just a natural manifestation of autumn.  I have often reflected that as this ash grows it would eventually take over the whole of the Square Metre.  Maybe Chalara fraxinea will prove me wrong.

Trailing tormentil confirmed

In my post of 11th June below I pointed out that in order to confirm the identity of what I thought was trailing tormentil (Potentilla anglica) I needed to see ripe seeds.  I have now managed to do this:

Ash and trailing tormentil

A kind of spring clean after a period of semi-neglect (which Emthree is quite happy with: it looks after itself to a degree).  I spent half an hour cutting back the new bines, nettles and fern in Brambly Hedge noting that everything is now growing very fast during this cool wet period after the May heatwave.

Many of the small plants I have become familiar with over the years are flowering, with heath speedwell, Veronica officinalis, doing particularly well, especially where the soil is poor and dry – on top of the meadow ants’ nest for example.

The ash tree by Hazel Edge has recovered from the severe pruning by rabbits over the winter and is now nearly one metre tall. The young leaves at the highest point are an attractive treacly maroon colour.

20120610 Metre young ash leaves (4)

The yellow potentilla has come into flower again (see picture below) and I also have a plant from Emthree cultivated in a pot. I have little doubt that it is trailing tormentil, Potentilla anglica, though I will need to wait until I have some ripe seed heads to be absolutely sure. Rich & Jermy in The Plant Crib (BSBI, 1996) say: “P. anglica and its hybrids, P. x mixta Nolte ex Rchb. (P. anglica x P. reptans) and P. x suberecta Zimmeter (P. anglica x P. erecta), are extremely difficult to distinguish from one another.” Also the hybrid P. x mixta is commoner than pure P. anglica. One additional clue I have is that last year I found a yellow rust on the leaves of the potentilla in Emthree and this turned out to be the rather scarce Phragmidium potentillae which, according to Ellis & Ellis (1985) has only been found on Potentilla anglica and P. tabernaemontani. The second of these, spring cinquefoil, is a rare plant in Sussex and has only been recorded from one or two sites well outside our area. It also flowers much earlier than the others.  The rust seems to be a first record for East Sussex.

Tomorrow I might prune some of the smaller trees - the hornbeam, the second birch – into one metre tall cordons.

Spring flowers & sallow seeds

Emthree is now starting to burgeon and it is good to see so many bugle flowers - probably the greatest number in the last nine years, though they nearly always flower in slightly different places.  Here the Cladonia lichen cover can also be seen on Butterfly Rock behind.

The grey willow/sallow, Salix cinerea, that flowered earlier in the year has already produced its fluffy bunches of seed as the catkins burst open.  They are very evanescent and will, I suspect, be gone by tomorrow.

Lawn Rectangle: a Square Metre satellite

At the end of June I am giving a talk on the wildlife of lawns at a seminar for the Wildlife Gardening Forum project to be held at the Natural History Museum in London.  As a bit of an angle for this I have set up a small rectangle of lawn in our garden for close study between now and the date of the talk and its progress can be followed here:

Rabbit dung fungi

Among other things a few rabbit pellets from the Square Metre produced some microfungi like orange blancmanges with slender spikes protruding: pale golden sea urchins.

20120404 (3) My mycological friend Howard Matcham has identified these as Lasiobolus ciliatus, a common species but a new record for Emthree.  He says to keep the dung for longer as other species are likely to appear.

Spring sallow: life and death

Yesterday for the first time the sallow tree (Salix cinerea) that was spotted as a tiny seedling in the Square Metre in September 2004 has catkins showing that it is a female plant.

20120321 (9) Metre Salix cinerea

A good thing to encounter on the first day of spring.

At the other end of the spectrum I noticed the intricate geometry of a decaying log on the edge of Medlar Wood.  It was put on the ground as a neatly sawn cylinder a few years ago, but now the ravages of time have worn it into intricate shapes.

20120321 (4) Metre log 

It reminded me of that immortal passage from Shakespeare's Tempest:

And, like the baseless fabric of this vision,
The cloud-capp'd towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Yea all which it inherit, shall dissolve                 

And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on, and our little life
Is rounded with a sleep.

Non-Euclidian Nature

Robert Pirsig in Zen and the Art of Motorcycle Maintenance wrote "Weeds and grass and wildflowers grow where the concrete has cracked and broken.  Neat, square, upright lines acquire a random sag.  The uniform masses of the unbroken color of fresh paint modify to a mottled, weathered softness.  Nature has a non-Euclidian geometry of her own that seems to soften the deliberate objectivity of these buildings with a kind of random spontaneity that architects would do well to study."

20120225 Metre grass b

Though Emthree is not part of the built environment, these non-Euclidian manifestations seem to me to be all too apparent in the 'weathered softness' of late winter.  These shapes, reminders of summer, have a past and a future.   The picture above is of tangled grasses, that below of cut, or bitten, bramble stems.

20120225 Metre cut bramble b

As spring advances and things grow upright, the spirit of Euclid will, to some extent, return.

Frosty February

We have now had two weeks of frost at night, with the temperature falling, at the coldest, to -8 Celsius.  Nine days ago it snowed and, while the temperature is now rising towards the seasonal normal, there is still much of the white stuff on the ground.

IMG_9736 On a brief visit to Emthree there were few signs of wild life but then I pay more attention to some of the remains of summer such as the dead ragwort receptacles below.  Their work ended long ago and they now rustle together like air fossils, the pepper pot receptacles surrounded by all-askew spiky phyllaries that once held up the golden flowers in a green embrace.

IMG_9742 These have a certain gaunt, scratchy kind of feel, but cold weather brings beauty as well.  Here is the upper part of the birch tree which was spotted as a seedling in the Square Metre in spring 2004.  The lower part of its trunk can be seen in the picture at the top of the page.

Sulphur tuft and a mild autumn

Weak December sunshine from a washed out sky.  There have been one or two frosts, but it is generally mild.

Emthree, in the open areas, has a covering of densely matted grass and I have started reducing this with a small pair of shears so that it does not prevent weaker plants from coming through.

20111203 Metre Hypholoma fasciculare 005There are far more fungi than usual: glistening inkcap (Coprinellus micaceus), candle-snuff fungus (Xylaria hypoxylon), sulphur tuft (Hypholoma fasciculare) - see above.  Also several kinds of, to me, virtually unnameable Mycena spp.

Midsummer Pond is full again after some heavy rain during the week and the ground is getting squelchy with mud underfoot.

November novelties

Despite the now decidedly autumnal weather, there is still plenty to enjoy in Emthree.  After a bit of sifting among dead leaves and general detritus, I found a few fallen box leaves colonised by the microfungus Sesquicillium buxi, a whitish powdering on the underside of the leaf:

IMG_9502 So far as I know, this has not been recorded from Sussex before.  Though it is probably quite common where box trees grow, I supposed it does not quite have the charisma of a snow leopard (though I fancy I can see an image of a snow leopard in the pattern).  Is it of equal worth I wonder?

20111116 (8)The ash tree in Emthree, now nearly seven years old, has been bitten off again about half a metre from the ground.  It seems quite high for a rabbit and not very appetising, so I suspect it might have been one of the visiting deer.  I am sure the plant will recover.

The St. John's Wort plants have many mines of the tiny hypericum pigmy moth (Ectoedemia septembrella).  It seems quite common in Emthree, and practically every leaf in the picture below appears to occupied.

20111116 (9)

Although it has turned quite cold and grey, there is still plenty to stimulate the imagination and I cannot agree with Thomas Hood:

No warmth, no cheerfulness, no healthful ease,
No comfortable feel in any member--
No shade, no shine, no butterflies, no bees,
No fruits, no flowers, no leaves, no birds,
November!

I am warm and cheerful; at least some of my members are comfortable; insect life is at a low ebb but there are plenty of fruits, birds and even a few flowers.

Leaf miners and fungi

Yesterday I was gazing (for no good reason) at the bilateral chains of heath speedwell (Veronica officinalis) leaves that spread across the Square Metre.  They seem to stand out at this time of year as the grass dies back.

Then on one leaf I noticed a dark track along the left hand edge.  This turned out to be a mine made by a larva of the fly Phytomyza crassiseta.  I once found an adult of this species in Shoreham-by-Sea, West Sussex, but this would appear to be a first record for the species in East Sussex.

20111107  (13) Metre Phytomyza crassiseta mineSince the heath speedwell arrived in the square in September 2005 it has attracted the scarce flea beetle Longitarsus lycopi, and now this fly.  In the picture above the shot holes in the leaf may have been made by the beetle.

The JNC  database list 11 species associated with this plant, but it is extremely unlikely that all of those would occur in Emthree.  I'll keep looking though, in case I can find some more and there is also a microfungus associated with this plant.

I also gathered up some of the medlars and have put them in a flower pot to see if they attract anything, animal or vegetable.  Today there was one female winter gnat (Trichocera) resting inside the pot, possibly interested in the fruit.

20111107 Metre medlars in flowerpot The other fruits that are very distinctive at the moment are the those of the black bryony (Tamus communis), high up in the medlar tree.

Coda

So much of each day is taken up with small things. 

I watch a pen gliding over paper leaving its black, twisted trails like drawings of leaf mines.  These word trails represent some sort of reality but only a partial account of what goes on in the brain.

The luminous multichrome internal fantasia that never ceases while we are awake cannot be replicated, or even approximated, in words.  Words are a faint music heard from the distant mountains of the nervous system, the Sierra Nervosa.  So much of what we feel and experience will never be expressed.

November reflections

Emthree is scattered with fallen leaves: yellow hornbeam, brown oak and sallow, pink spindle.  I am starting to visit more regularly and have been looking for microfungi, mines and galls on the dead leaves, but have not found much yet.

Still, I can tidy the area by picking up a small boxful of leaves and then have the pleasure of sorting through them, lens in hand, in the warmth of the sitting room.

20111105 Metre Butterfly Rock Butterfly Rock is very colourful just now and the fairy cup lichen is covering a greater area than ever before.  It looks to me like Cladonia fimbriata,  from their golf-tee shape, perhaps mixed with another Cladonia.  Simon Davey, in 2008, said that Cladonia on this sandstone rock were C. pyxidata, but that was on the basis that they were not golf-tee shape.  Maybe we have had three Cladonia spp. here.  The grey patches are another lichen, supposedly Lecanora campestris, but I am not too happy with that determination.

I have just read (at one sitting) Peter Medawar's The Limitations of Science published in 1984.  He ends with the famous line from Voltaire's Candide: "We must cultivate our garden." (Il faut cultiver notre jardin.).  I suppose my long involvement with Emthree has been one kind of example of that.  It is my 'garden', though whether what I do can be construed as cultivation or not is a question.

My aim is not to generate produce to feed or clothe the body, or to manufacture artefacts (though I am currently using medlars from the area for some recipes) but material to feed the mind.  It is a privilege to watch the ebb and flow of this small area's teeming life with all its beauty and wonder, from neatly coiled snails with their regularly etched shells under bits of dead wood, to the fluttering yellow leaves hanging on the sky-bound top of the seven year old birch tree.

Emthree is a vortex of life and sometimes I fancy I can see through the kind of glass St. Paul saw through darkly that Emthree is in a sense the entire universe enfolded, with myself in its loving embrace, into a small flake of biosphere on the surface of Planet Earth.

Brown birch bolete, Leccinum scabrum

This project entered its 9th year on 15 September and today I had a find worthy of the event.  In the north west corner of the Square Metre itself was a fine example of the brown birch bolete (Leccinum scabrum).

20110918-20 BHW walk Metre 003 The toadstool is found with birch and must have a mycorrhizal association with one, or both, of the birches in Emthree, one of which is now of substantial size.

The top of this fungus was wet with rain, justifying the name of penny bun toadstool, but the underneath and stipe were characteristic of the species.

20110918-20 BHW walk Metre 006I am sure it will attract many fungus gnats (Mycetophilidae and relatives) and maybe other species of insect I will see what I can breed out from the numerous larvae that invariably burrow their way through the flesh of these toadstools as they mature.
