New Scientist – Our Daily Bread

Some very fine loaves (Title Photo)

Dear Readers, during the first lockdown it suddenly seemed as if every second person that I spoke to was experimenting with sourdough bread. I imagine there were many reasons for this – the extended period at home meant that the starter could be nurtured, for one thing. For another, there’s something about kneading the dough that is very therapeutic – I have certainly gotten Zoom calls out of my system by being overly assertive during bread-making. And then there’s that sense of connection with all those generations of bread-makers who went before. The fact that many of my loaves turned out like slightly-more-porous bricks didn’t take away from the sense of accomplishment – at least the bread had the right smell and appearance (generally).

But what I hadn’t thought about was that sour dough in particular actually gives us a connection not just to our ancestors, but but to the unique microorganisms that live in our houses, and even on us.

In New Scientist, someone raised the question of why sourdough tastes so different in San Francisco compared to the loaves in London. To understand why, it helps to know a bit about the process of making it.

Most bread (including my bricks) is helped to rise using commercial yeast, either fresh or dried. But sourdough is different. Water and flour are mixed together and then exposed to the natural microorganisms in the air. The yeasts produce the carbon dioxide bubbles as they respire – this is what enables the bread to rise during proving and cooking. But other bacteria (particularly from the Lactobacillus genus) produce lactic and acetic acid, which contribute to the flavour. The flour also contains bacteria  – as you might expect, the less processed the flour, the more opportunity for microorganisms to survive, and to contribute to the flavour of the finished load.

Then, there are the bacteria that live on us, particularly our hands (hence all the calls for increased hand washing during the pandemic). Some people swear that the loaves made by a particular baker can be identified purely by the taste that their bacteria impart. This is about as far as you can get from the identical loaves created in supermarkets and commercial bakeries.

The amount and type of water added to the loaf will affect the final result – a wetter loaf makes it easier for the dough to rise, but the flavour of the water will also add its own special twang. Plus, sourdough needs a long, slow fermentation, and during this process different microorganisms will thrive or die, according to the conditions in which the starter is kept – different temperatures will affect different bacteria.

As the loaf containing the starter is baked, the yeasts first go into overdrive because of the heat, producing the carbon dioxide that contributes to the rise. But as the heat continues to increase, the yeast can no longer metabolise and finally they die, along with the vast majority of the bacteria. It seems like a poor reward for all the work that these microorganisms have done, but it’s all the better for us humans.

However, the rest of the starter remains.It’s easy to forget that a sourdough starter is actually a living thing, a community of microorganisms. The starter should be fed regularly and can last for years if properly looked after.  Maybe this is part of the reason for the whole sourdough phenomenon – the sense that what is being made requires careful nurturing and is also completely individual must add to the pride at the finished result. No wonder that, in Sweden, a ‘sourdough hotel’ was set up to look after your sourdough starter when you went on holiday, feeding it with the requisite amount of flour and making sure that it didn’t dry out.

So, over to you readers. Have you been ‘sourdoughing’ during the pandemic, or before? I am tempted to give it a go, but oh! the responsibility. I know that the whole phenomenon has taken on the aura of extreme middle-classness here in the UK, with the notion that sourdough can only be created if you have an Aga and a man-bun (if you’re a chap) and if you holiday in a yurt (presumably taking your starter with you), but I do know some perfectly non-yurty people who swear by the whole process. Let me know what you think!

 

Sunday in the Pond

Dear Readers, after a chilly couple of weeks I was delighted to see that the tadpoles are finally emerging from their spawn. What extraordinary little question marks they are! In the photo above you can see some tadpoles that are quite well grown and others, like the one with the straight tail that seems to be ‘crossing swords’ with the one above, who have just struggled out of the egg. Most of them are currently hanging around the plants, but one or two brave souls have crossed the pond to feed on the abundance of algae growing on the liner.

In the photo below I love the way that the shadows of snail and pond skater can be seen on the bottom right, while a lone tadpole keeps a very low profile. The pond skater went over to investigate the snail, but these insects are largely scavengers, who will take advantage of any invertebrate unfortunate enough to fall into the water. You might sometimes notice ‘rafts’ of pond skaters all feeding on a dead bee or clumsy fly. They have the piercing mouthparts of all bugs, and will make short work of any little corpses.

Pond skaters are superbly adapted to living on the surface of the water – their bodies and limbs are covered in tiny hairs which increase the insect’s surface area and make it easier for it to stay on the surface. If the creature is submerged by a wave (not likely on my pond where all is currently tranquil) the air bubbles trapped in the hairs will help the insect to right itself. The long middle legs are used for ‘rowing’, the back ones for steering, but to the naked eye they seem to move across the water by magic.

For pond skaters it’s all about the vibrations that they can feel through their limbs – they take a while to settle down if I walk past, even if I tiptoe. Once they’re relaxed again, you can see all sorts of shenanigans going on. Pond skaters signal to one another using different frequencies: one to repel, one as a threat, and one to signal amorous intentions. When two pond skaters notice one another, one will send out a ‘repel’ signal. If it isn’t responded to by another repel signal, or even a threat signal, the pond skater knows that it’s happened upon a female, and will send out a courtship signal. A receptive female will respond with a courtship signal, and the male will then mate and stay with her until her eggs are laid. This means that the female (who is larger than the male) will have to ferry her lover about, possibly for weeks.

Pond skaters in flagrante (Photo One)

When the young hatch, sometimes they will have short wings, sometimes long wings,  and sometimes no wings at all. Wingless forms obviously can’t leave the water body where they were born, but this isn’t a problem if there is plenty of food – I suspect that ‘my’ pond skaters hibernated in the pond over the winter to get a head start this spring. However, if a pond gets too crowded, or dries up, it’s useful to have wings so that the young can disperse – short wings enable a local flight, long wings can carry the new pond skaters to exciting new ponds and lakes. However, this has to be balanced against the disadvantages of wings for a surface-living insect like a pond skater – wings are extra weight, and can get tangled. It’s likely that because my pond is stable and the water level is lovingly tended by a mammal (me) most of ‘my’ pond skaters will be wingless. I shall pay attention over the next few months and see what happens.

Although pond skaters in the UK are modest little chaps, the Giant Pond Skater of Vietnam (Gigantometra gigas) has a ‘legspan’ of twelve inches, and you can read all about them here.

While I was sitting on a stone with my camera trained on the pond skaters, who should pop by but Bailey King of the Cats. He is now twenty years old, and so a little bit stiff, but he is still every bit the monarch that he was previously, so much so that his minions (aka his owners) popped by to pick him up and take him home.

Bailey asking where his taxi is.

And finally, here is a little film of the goings on in the pond. Do not be alarmed (overly) by the appearance of two leeches from under the edge of the plant pot – this species lives by funnelling up tiny invertebrates and so the tadpoles will go unmolested.

A Mid-April Walk in St Pancras and Islington Cemetery

Dandelions!

Dear Readers, it was a beautiful day for a walk in the cemetery. It’s warmed up a bit, and the dandelions and daisies are open to the sun. When I started this blog, I thought that a dandelion was just a dandelion, but things are much more complicated than that – botanists have identified more than 230 separate microspecies of Taraxacum officinale (the common dandelion) in the UK alone. While some dandelions reproduce in the normal way, by seed, some populations are clones of one another because they spread only asexually. I suspect that the detail is much more complicated than that, but that’s as much as my brain can cope with before it explodes. Let it be said, though, that those butter-yellow flowers are extremely useful for pollinators, and that the dandelion ‘clocks’ that will follow are as much fun now as they were when I was a child.

Incidentally, ‘Taraxacum‘ is thought to come from the Arabic word for a bitter herb, though it might also be related to the Latin word for ‘to disturb’. ‘A bitter herb that grows in disturbed places’ is about as good a description of a dandelion as you’re likely to get. As regular readers will know, whenever a species is designated as ‘officinale‘ it means that it was a highly-regarded medicinal plant, the ‘official’ one to use.

And while we’re on the subject of etymology, on a day like today it’s easy to remember that ‘daisy’ is thought to derive from ‘the day’s eye’. You can almost feel the flowers drinking the sun in on a day like today.

 

I had to have a quick look at the horse chestnut to see how the leaves and flowers were coming along. Very well, it seems.

And how about this small white butterfly (Pieris rapae), my second of the year? You can tell that it’s a female because of the three spots on the upper wing (males just have one spot), and you can tell it from a large white (Pieris brassicae) because the wing tips are pale grey, rather than black in the bigger species. I suspect it will be off to lay its eggs on the Jack-by-the-hedge (garlic mustard) which seems to have popped up overnight.

Last week I was lamenting that the lesser celandine has already gone over, but I spoke much too soon – in some places it’s blanketing the ground, making a patchwork with the primroses, the daisies and the aforementioned dandelions. Yellow is definitely the colour at the moment.

Lesser celandine

And here was a real treat. I heard a bird call, and spent some time looking for the songster. The call sounded familiar yet strange, as if I was remembering it from a long time ago.

 

The stubby tail, yellow-green plumage and chunky beak gave it away as a greenfinch (Carduelis chloris). This was an extremely common garden bird, forever bullying the goldfinches away from the seed feeders and more than holding its own on the bird table. Sadly, a parasitic disease called trichomonosis had a devastating effect on populations in Europe – it’s thought that greenfinch numbers might have dropped from 4.3 million birds to 2.8 million during the period to 2006. As there is less food in the countryside for finches due to more efficient harvesting techniques, the decline of hedgerows and increased use of herbicides and pesticides, they have moved into gardens, where the concentration of birds helped to spread disease. However, the numbers seem to be recovering, and it was certainly a pleasure to see this little chap singing his head off.

Further into the woody part of the cemetery I noticed some yellow archangel (Lamiastreum galeobdolon ssp argentum). This is the garden variety, with its variegated silver leaves – the plain green-leaved variety is a native, but I have a suspicion that this variety has more tolerance for shade, and it also flowers earlier. It’s very pretty but doesn’t seem to be as attractive to insects as white and red deadnettle.

And here is the garlic mustard (Alliaria petiolata), just waiting to pop into flower. The kidney-shaped leaves are not typical for a brassica, but the garlicky smell of the crushed leaves makes me think that maybe this was once a useful addition to an otherwise bland diet: many other wild members of the cabbage family also have interesting flavours, be they peppery like mustard or wild radish, or oniony as with this plant. Plus in addition to the ‘cabbage white’ butterflies, this is a favourite foodplant of the caterpillar of the orange-tip butterfly (Anthrocharis cardamines), who might derive some protection from the flavour of the leaves, which probably make it a pungent little mouthful.

Garlic mustard (Alliaria petiolata)

And I hope you’ll excuse a few more photos of the lesser celandine. It feels as if they are at their absolute height of perfection this week, and it’s such a joy to see them.

And in keeping with our yellow/green theme, the flowers of the field maple are emerging, so new and fresh. I am really hoping that this is a field maple (Acer campestre) rather than a Norway maple (Acer platanoides) but let me know, readers, it’s the only way I learn 🙂

And finally, as I head back past the War Graves part of the cemetery, I pause to look for the stumpery that I’d photographed on previous visits. But it’s gone, along, it appears, with another tree. I imagine that the stump might be the result of honey fungus, though it was a most interesting and varied spot. Still, in its place is a neat pile of logs, and I suppose I’ll have to be content with that. There are plenty of spots in the cemetery that are overgrown and perfect for wildlife, so I shall have to forgive the powers-that-be for their spot of tidying-up.

Saturday Quiz – International Orchid Appreciation Day!

Title Photo byVelella, CC BY-SA 3.0 <https://creativecommons.org/licenses/by-sa/3.0>, via Wikimedia Commons

Title Photo – Dune Helleborine (Epipactis dunensis)

Dear Readers, on 16th April it was International Orchid Appreciation Day. Who knew? There are 26,000 species worldwide, but for this quiz I am going to concentrate on the European ones. Many of them are named after their physical features, although with some of them I fear that you’d have to squint to see the resemblance. However, I have every confidence that you will be able to match the photo to the species without TOO much trouble.

As usual, answers in the comments by 5 p.m. (UK time) on Thursday 22nd April, and as usual the answers will pop up on Friday. I will ‘disappear’ your answers as soon as I see them, but do write them down first if you are easily influenced (like me). Have fun! I was amazed at how many of these beautiful plants we have in the UK, nearly all of them scarce or rare. How I would love it if some of them popped up in my garden, but as it is I think I’ll have to make do with the green alkanet.

Just match the name to the photo. So, if you think the orchid in Photo 1 is a Military Orchid, your answer is 1)A.

Onwards!

My goodness, lovely readers, this was a close run thing this week! Everyone did exceptionally well. If you remember, I was giving one point for selecting the correct country, and a second point for identifying the breed. On this basis, we have Anne and Fran and Bobby Freelove with 26 out of 30, but our winners this week are Claire, Sylvie and Mike from Alittlebitoutoffocus with 28 out of 30 – well done to all of you! Let’s see what I can come up with for tomorrow…

Small Beauties

Fritillary

Dear Readers, we’re into my ‘busy week’ at work, which means lots of reports have to be written and lots of project managers need to be talked to. Some days I plonk down at 7.30 a.m. and suddenly realise it’s 5.30 p.m. and I’ve only broken for a twenty-minute lunch. So it feels even more important to schedule in a quick walk around the garden, even if it’s only for ten minutes. It’s astonishing what you can find!

For example, I had never really noticed the snakeskin pattern on the fritillary before (even though one of its names is ‘snakeshead fritillary). This was a very fine example, especially against the bright leaves of the mock orange. Let me tell you now that half an hour spent popping in the bulbs in October provides an excess of joy in spring. You can never have too many bulbs!

I’ve grown some very pale blue grape hyacinths this year, but as usual the ‘ordinary’ blue ones seem to be doing best.

Grape hyacinth

The marsh marigolds are just coming into bud, and when did the flag irises start to get so tall?

I pop into the shed to dig out some bird seed (mainly for the squirrel it has to be said, if he gets any chubbier he won’t be able to walk) and I noticed this stunning cobweb behind the door. We have so many spiders that I honestly think the shed will be listed as a Site of Special Scientific Interest soon. This web was probably made by a cellar spider (one of those very skinny chaps who vibrate up and down when disturbed). Strangely enough, these etiolated-looking spiders, who wouldn’t appear to be strong enough to say boo to the proverbial waterfowl, are themselves spider-killers, finishing off all manner of other species.

And finally, the flowering currant is still going strong, and is now attracting female hairy-footed flower bees. These are tricky to photograph, being fast and flighty, but I did manage to one satisfactory photo. If you look closely you can see the ‘hairy’ ginger legs, used as a pollen basket by the female.

And finally, I was sitting back at my desk, just about to tackle my most imposing project, when there was a fluttering outside and this butterfly landed on the windowsill. This is a female small white (Pieris rapae), described in my Garden Wildlife book as being often the first butterfly of the year to emerge from its chrysalis. No doubt she will be off to find a) a male and b) a cabbage to lay her eggs on as we speak.

And so, it’s back to work. Roll on Friday!

 

 

 

Wednesday Weed – Field Wood-Rush

Field Wood-Rush (Luzula campestris)

Dear Readers, I know that some of you gardeners might disagree, but I was charmed by this little plant, growing on one of the grassy banks in a sunny part of the cemetery on Saturday. Look at those lovely hairy leaves! These are a distinctive feature of the wood rush family, who all belong to the genus Luzula. Luzula might come from the Italian word lucciola, meaning ‘to sparkle’, probably a description of how the plant looks when it’s wet with dew. Another derivation could be the Latin word ‘luculus’, meaning a summer field, or a small place. Whatever the original meaning of the word, I have rather fallen in love with this plant, hiding in plain sight as it is. My photos are good enough for identification, but to see the full prettiness of the

Flowers of Field Wood-Rush (Photo by By Leo Michels  Own work, Public Domain)

I note that the plant is also called ‘Good Friday Grass’, from its habit of springing into flower at Easter (it was pretty close this year, but as the date moves by several weeks I am not totally convinced). It is also known as ‘sweep’s broom’, for obvious reasons. It is found right across temperate  Europe and into the Caucasus. North American readers might recognise its very close relative Heath Wood-Rush (Luzula multiflora) – indeed, some botanists think that it might be the same species. To add to the complications, Heath Wood-Rush is also found in Europe, including the UK, and looks very similar. Both species like short, unimproved grassland, with Field Wood-Rush being particularly fond of acidic conditions: the RHS suggests that build up of ‘thatch’ (the dead stems and leaves of grass and other plants) acidifies the soil, and helps the wood-rush to thrive. Both species are also described as ‘pests’ in ornamental turf such as golf courses, and the RHS suggests using lime to change the pH of the soil to get rid of it. On the Pitchcare website, the author has a historical perspective, relating how Field Wood-Rush became a problem when poor pastureland was ploughed over to grow crops during the World Wars.  Personally, I think that a grassy area is much more interesting with a variety of plants in it, and lots of other creatures would agree, though possibly not golfers, bowlers and golfers.

All of the wood-rushes provide food for moths. The Smokey Wainscot (Mythimnia impura) is one species whose larvae will munch their way through the leaves, hairs and all, before overwintering as a tiny caterpillar. I love the very marked veins on the wings of this moth, and the fringes around the edges – it looks rather like upholstery fabric!

And how about this little chap, with his ridiculously long antennae?  Coleophora otidipennella is a micro moth without a common name, and the larvae feed only on the seeds of the wood-rush.

You might sometimes find yet another Luzula, Greater Wood-Rush (Luzula sylvatica) in woodland, and there are several ornamental varieties. I think it could be a fine choice in a particularly shady spot where nothing else will grow.

I keep seeing references Field Wood-Rush as being ‘one of our commonest grassland plants (and for some rather lovely photos of the plant in situ, have a look here). I am astonished that I’ve never noticed it before, and I love that even after seven years of a more-or-less weekly ‘Wednesday Weed’ I am still finding new plants. I also love that the Lorn Natural History Group website refers to it as ‘a happy little plant’ as this was exactly the impression that I got. I know that anthropomorphism is deeply unfashionable, and for sure most of the time I am projecting: this plant makes me feel happy, so how could it not be happy itself, flowering away on a sunny spot? There is a deep satisfaction from both finding out what on earth a plant ‘is’ according to our classification, and also noticing our own reactions, and being curious.

And so, to a poem. As you might expect, finding a poem about ‘Field Wood-Rush’ proved to be impossible, but looking for ‘Good Friday Grass’ brought up this vignette by Edwin Morgan. Morgan was a wonderful poet who wrote extensively about the poor and dispossessed of Glasgow, but I think this poem can be read on many levels – it’s about an incident that I’m sure will feel familiar to many of us, but it’s about lots of other things too. See what you think!

Good Friday

by Edwin Morgan

Three o’clock. The bus lurches
round into the sun. ‘D’s this go –‘
he flops beside me – ‘right along Bath Street?
– Oh tha’s, tha’s all right, see I’ve
got to get some Easter eggs for the kiddies.
I’ve had a wee drink, ye understand –
ye’ll maybe think it’s a – funny day
to be celebrating – well, no, but ye see
I wasny working, and I like to celebrate
when I’m no working – I don’t say it’s right
I’m no saying it’s right, ye understand – ye understand?
But anyway tha’s the way I look at it –
I’m no boring you, eh? – ye see today,
take today, I don’t know what today’s in aid of,
whether Christ was – crucified or was he –
rose fae the dead like, see what I mean?
You’re an educatit man, you can tell me –
– Aye, well. There ye are. It’s been seen
time and again, the working man
has nae education, he jist canny – jist
hasny got it, know what I mean,
he’s jist bliddy ignorant – Christ aye,
bliddy ignorant. Well –’ The bus brakes violently,
he lunges for the stair, swings down – off,
into the sun for his Easter eggs,
on very
nearly
steady
legs.

LNHS Talks – Urban Foxes by Professor Dawn Scott

Dear Readers, as you will know I am a great fan of our urban foxes, and so I was looking forward to this talk very much. Prof. Scott did one of the earliest and most extensive studies of urban foxes in Bristol, and much of what she found has greatly informed our understanding of these animals.

Prof. Scott is very interested in how animals adapt to urban landscapes, and why some do better than others. She describes cities as ‘landscapes of fear and opportunity’. The opportunities include that cities are warmer, there are less predators, more food (especially as people deliberately feed year-round), lots of niches for refuge, and consistent water supplies. There is, however, less natural food, more competition, a higher risk of disease as territories tend to be smaller, danger from the roads, from some pets, and also, of course, a high risk of conflict with people. The animals that tend to do best are enterprising generalists – this includes foxes, but also badgers (who are increasingly being seen in the suburbs) and hedgehogs (who are now commoner in urban areas than in many places in the countryside).

Prof. Scott described how adaptation to city life for an animal usually includes an increased density of animals (as there are more food resources), higher aggression (because of competition for those resources) and much less fear of humans – this is known as ‘synurbanisation’. She considers that the extraordinary ability of the fox to navigate the 3-dimensional structures of the city to be one of its key skills in making the city its home – she tells of finding foxes living on roofs and in trees. Anyone who has seen a fox effortlessly bound over a six-foot fence will be nodding their heads in agreement.

Prof. Scott believes that an understanding of the fox would help to offset some of the hostility that people feel towards the animal. Socially, foxes tend to live in groups of 3 or 4 – typically a small ‘family’. However, foxes forage for food on their own once they’re into adolescence. They communicate mainly by smell, which explains the piles of poo and that heavy ‘foxy’ smell that they produce – it’s thought that the scent messages might include sex, breeding status and even dominance. As anyone who has been woken up in the night also knows, foxes communicate by sound too – there are over 28 different calls, including the screaming of vixens, the barking of dog foxes and the various bouts of yipping that can enliven many an early morning. However, the screaming is only likely to be heard in December – February, when the vixens are in heat and, apart from a lot of chaos when the cubs leave the den in May, foxes are generally fairly quiet for the rest of the year. Females will have a natal den where the cubs are born (frequently under a garden shed it seems), but they will move the cubs if disturbed, and adult foxes will have several rest sites in their territory where they hide during the day. They are largely, but not exclusively, nocturnal, as the foxes who turn up in my garden will attest.

Only one in five foxes will live to be two years old, with roads claiming the majority of victims. In captivity, foxes can live ten to fourteen years on average.

On the vexed question of whether we were becoming ‘overrun’ with urban foxes, Prof. Scott looked back through the records, and had done several scientific studies of her own. Her view was that urban foxes had certainly spread – in the 1980’s, 91% of cities had no urban foxes, but now most of them did, with the foxes spreading north and west. Her study in Bristol showed that there were approximately 36 foxes per square kilometre. However, in 2010 a devastating outbreak of mange killed 95% of the foxes in the city.

Prof. Scott showed several photos of foxes, some with mange, some who were simply shedding their winter coats. One way of telling is obviously bare, sore flesh, but a real giveaway seems to be if the tails are looking scratty – this is a clear sign of mange. Healthier foxes seem to be able to just shrug it off, but for foxes already weakened by bad nutrition it can be a death sentence. Furthermore, there’s no easy solution: the jury is out on the homeopathic solution that can be given without harm (and possibly without any positive effects either) but the normal veterinary treatment can only be given under controlled circumstances. Furthermore, Prof. Scott found that foxes who were taken into sanctuaries for treatment and then released back into their old territories nearly always found that a new fox had taken over their old home, and the original incumbents were usually driven out, with all the concomitant dangers of being run over as they searched for a new territory. Prof. Scott’s opinion was that, hard as it seems, mange is something that limits the numbers of foxes in an area when they get too high – it thrives in conditions where there are lots of foxes in close proximity. A more ‘usual’ population of foxes seems to be about 12 foxes per square kilometre, something seen in more recent studies in Bristol (post mange) and London.

High concentrations of foxes are often supported by feeding. In a recent study, Prof. Scott found that 36% of the people in her study fed foxes, mostly either by hand or at the back door. One fox in the study spent his whole time waiting outside the house where he was fed at 8 p.m. and then moving to house number two where he was fed at 10 p.m. There are issues around what was fed (foxes definitely like jam sandwiches but are unlikely to make them for themselves), and the danger of allowing foxes to associate people with food. Some of the more lurid headlines seem to feature foxes who feel perfectly comfortable going into people’s houses and making themselves at home, often biting people when cornered. Prof. Scott’s advice is to feed little, feed something appropriate (like dog food) and not to feed too close to the house, and certainly never by hand.

And finally, one of the questions that Prof. Scott is frequently asked is ‘do foxes kill cats?’ Well, we’ll never know for sure that there isn’t a rogue fox out there with a taste for felines, but judging by the trail camera evidence, a solitary cat can see off two foxes who attempt to snaffle her tea. Apparently in all the filmed incidents, the cat beat up the fox. Badgers trump foxes and cats, however, although there was no evidence that badgers actually hurt cats. One film clip showed a hedgehog feeding, at which point a fox picked it up and deposited it elsewhere before coming back to eat the food. It’s easy to see that that’s a situation that could lead to the fox predating the hedgehog.

So, this was a very interesting talk, with a lot of thought given to how people and foxes can live together more harmoniously. Prof. Scott thinks that understanding the fox is key, and I agree – as with everything, knowing the reason for something (such as night time screaming or piles of poo) can make it a lot more bearable. I for one love to see the touch of wildness that the fox brings, and am happy to put up with a little inconvenience for the pleasure of their company.

You can watch the whole of the talk here. Highly recommended.

The Dead Wood of Coldfall Wood

Dear Readers, we all love a good tree, but what about when it’s felled or trimmed or comes to the end of its life? I took a walk in Coldfall Wood on Friday with my good friend A, as people generally don’t seem to appreciate how important dead wood is to the ecology of woodland. Just look, for example, at the moss growing on these logs. There will be all kinds of invertebrates living under the bark, and no doubt mice and beetles and all sorts of other creatures will be living in the interstices. In time the whole lot will rot down (with the aid of a whole army of fungi, insects, bacteria and other detritivores) and return to feed the new trees that will grow up in the space that the tree once occupied.

There are wood piles from when some of the trees were coppiced a few years ago, and, whilst you can only see the fungal fruiting bodies later in the year, they host a whole range of different species.

Standing dead trees can provide roosting holes not only for the obvious candidates, such as woodpeckers and nuthatches, but also for birds such as this stock dove. These are shy little birds, smaller than a wood pigeon, with what I always think of as ‘kind’ dark eyes.

Dead trees often have a kind of grandeur and beauty all of their own. I love the peeling bark on this one, and the variety of colours on its trunk.

The Conservation Volunteers are an organisation who do a lot of work in the wood, including creating these dead hedges to protect areas from trampling. 95% of people recognise that these are meant to be a barrier. 5% take it as a challenge, and the hedges are sometimes dismantled, with the branches ending up in ‘dens’. Part of the reason for taking these photos with Friend A was to design some signage so that people know what the dead hedges are there for, so maybe we can get them left alone for longer. Getting the balance right between people exploring and experiencing the wood and its long-term survival so that future generations can also enjoy it sometimes feels like a real uphill battle, but it’s important to remember that most people do respect the woods, and that many of those who don’t are doing so out of ignorance rather than malice. Many of us seem to have become so divorced from nature and its patterns that we really don’t have the first idea about how to treat a ‘wild’ place.

A rather lovely dead hedge

And to cheer me up, the marsh marigold in the woods is in flower a good week before the one in my garden pond. There’s nothing more heartening than that glimpse of gold amidst all the green.

And hidden away, almost below the bridge, there are some enormous violets, definitely ‘blushing unseen’.

And of course some forget-me-nots.

So, let’s see where we get to with our ‘dead wood is good wood’ posters. Will they all end up in the stream? It’s possible, but I do hope that at least some people will realise that the hedges are there for a purpose, not just to be annoying. I will keep you posted!

The End of the Blossom in St Pancras and Islington Cemetery

Leaves are out on the cherry plum

Dear Readers, on a rather chilly blustery April day it was no surprise to see that most of the blossom on the cherry plums in the cemetery had given up for the year, to be replaced by the familiar magenta-brown leaves. Such are the pleasures of spring – blink and you’ll miss them, so speedily do the changes come at this time of year. But fortunately, as one plant ‘goes over’ so another takes its place.

Wood forget-me-knots and Herb Robert

The forget-me-nots in the woodland grave area are in full swing, but if you look very carefully you’ll see a tiny rose-red flower nearly in the centre, which I think is the first herb Robert flower that I’ve seen this year. Soon they will be everywhere, but as herb Robert was the first ever Wednesday Weed back in 2014 I will always have a soft spot for it, even if it does smell of rubber tyres. No one is perfect after all. And what is this popping up? A euphorbia for sure, and I suspect wood spurge but a ‘domesticated’ variety (Euphorbia amygdaloides var robbiae). Let me know what you think, readers.

Some cuckooflowers are in full flower further along the walk through this part of the cemetery. I say hello to the swamp cypress but it is still in its winter sleep, so I have spared you yet another photo of twigs. However, I do point out to my long-suffering husband that the cuckooflower (otherwise known as lady’s smock) is a member of the cabbage family and I know that my work is done when he sighs and says ‘I know’.

 

Cuckooflower (Cardamine pratensis)

I notice this rather strange hairy plant growing alongside some of the graves in the open area next to the main road. I have not the faintest idea what it is, but my pals over on the Wildflowers of Britain and Ireland Facebook page come back with the news that it is field wood-rush (Luzula campestris) within about 30 seconds. I shall say little about it now, but I feel a Wednesday Weed coming on…

Field wood-rush (Luzula campestris)

The red deadnettle and ground elder is having a right old time of it under some of the horse chestnuts. It’s hard to do justice to these pretty little plants from a distance, but if I lay on my stomach to photograph them I fear that I’ll need a hoist to get me back up again.

And speaking of the horse chestnut, isn’t it coming on well?

The primroses have taken over from the lesser celandine in the more exposed parts of the cemetery

I think these are the female catkins of goat willow, but feel free to correct me! I find catkins rather confusing.

What I told you all was feverfew a few weeks ago turns out to be (ahem) Oxford ragwort (Senecio squalidus) – not quite sure how I can have mistaken the leaves are clearly very different.

And look at the cherry laurel, just coming into full flower! Once it warms up a bit the bees will be delighted, especially the queen buff-tailed bumblebee that I saw earlier who was attempting to feed from a bunch of artificial flowers. There are quite a few real plants in flower, as we’ve seen, so hopefully she’ll spot them soon. I sometimes wonder if the super-sized and coloured plastic flowers act as a kind of ‘super-stimulus’, enticing bees away from things that will actually feed them. I hope not.

Cherry laurel flowers

I was delighted to see that my mallard mènage a trois were back on the bank of the stream.

The male mallards really are in spectacular condition, even though one of them appears to have no head :-). I have a special fondness for those little curly feathers just above the tail, which appear to be called the ‘sex feathers’ because only the drakes have them. I’m sure they should be called something cuter than that.

And look, the first flowers are appearing on the cow parsley/Queen Anne’s Lace (Anthriscus sylvestris).

For a final treat this week, here are some violets, coming into bloom just as the lesser celandine are finishing. For the next few months it’s just one thing after another, but in a good way for a change. Now if only I could replicate that changing cast of characters in the garden, without any weeks when everything looks a bit ugh, I would be very happy.
