The Twelve Plants of Christmas – Day One (December 25th) – Holly

Dear Readers, this year I thought I’d take a look at the plants that are associated with Christmas, not just here but around the world. But what better to start with than holly? I first wrote about this plant in 2014 when I was just a baby blogger, but it has cropped up on several occasions since. My original post is below, but for today I thought I’d capture some of the folklore around the plant (with thanks to Richard Mabey’s Flora Britannica as usual).

First up, in the south of England holly in a hedgerow is often allowed to grow into a small tree. Various reasons are given for this, but one is that witches run along the tops of hedgerows, and are therefore stopped by encountering a prickly plant. Personally I would have thought that they’d jump onto their broomsticks and zoom over the top (I certainly would :-)) but there we go. It was also thought to be because holly was ‘the King’s tree’ – some people thought this meant the King of England, but others thought it was a reference to Jesus.

However, Mabey points out that many people nonetheless cut boughs of holly to bring into the house at Christmas, as a protection against ‘house goblins’, and for fertility – though holly is seen as a symbol of masculinity, it’s the female flowers that actually bear the berries. Some of the regional variations include:

  • Holly being used instead of a Christmas tree in Cornwall
  • Holly not being brought into the house before 25th December (Dorset)
  • A holly leaf being placed in every room of the house for Christmas (Yorkshire)
  • Holly being the only greenery left in the house after Twelfth Night – it’s stuck behind a picture rail or mirror, and then taken down and burned on Shrove Tuesday on the fire used to cook the first pancake (Shropshire)
  • If a holly leaf falls out of a Christmas decoration, it should never be burned (Lancashire)
  • Holly used in decorations should be burned in the garden afterwards, for good luck throughout the year (Hampshire)

Well, that really is pretty confusing, and I would love to know if you have any particular superstitions related to this plant where you live. I wonder how much of the folklore is truly regional, and how much is down to a particular family tradition? What  is clear is that holly is seen as being a very powerful plant, with its pre-Christian heritage being happily absorbed by stories such as the Crown of Thorns when Christianity came along. Speaking of which, there seems to have been a change in fashion when it comes to the tune of the carol ‘The Holly and the Ivy’. I grew up with this one. But increasingly I’m hearing this one. What do you think, Readers? The second one is certainly jolly, but I’m rather partial to the first one.

Incidentally, I bought some of these berries in Marks and Spencer to pretty up some foliage that I had (not enough holly in the garden to pick as it’s just a baby plant) and guess what? This is not what we think of as ‘holly’ (Ilex aquifolium) but a different holly called Winterberry (Ilex verticillata) which is native to Canada and the US. I guess it doesn’t have prickly leaves, and does have lots of berries, so I can see its appeal to florists. The berries are apparently popular with birds, so I shall collect any that fall off, and hang the branches up later. Though it occurs to me that maybe they’ve been sprayed. Sigh.

Winterberry (Ilex verticillata)

And here is a poem, by Seamus Heaney. What a poet he was. What a legacy he has left.

Holly – Seamus Heaney

It rained when it should have snowed.
When we went to gather holly

the ditches were swimming, we were wet
to the knees, our hands were all jags

and water ran up our sleeves.
There should have been berries

but the sprigs we brought into the house
gleamed like smashed bottle-glass.

Now here I am, in a room that is decked
with the red-berried, waxy-leafed stuff,

and I almost forgot what it’s like
to be wet to the skin or longing for snow.

I reach for a book like a doubter
and want it to flare round my hand,

a black letter bush, a glittering shield-wall,
cutting as holly and ice.

And now, let’s journey back to 2014 and see what I said then.

Common Holly (Ilex aquifolium)

‘Of all the trees that are in the wood, the Holly bears the crown’. Could there be a better plant than the noble Holly with which to celebrate Winter Solstice and Christmas? The Holly King is said to rule from Midwinter to Midsummer, carrying life through the winter in his leaves, until the Oak King takes over for the rest of the year. Right into the twentieth century, people would use small Holly trees as Christmas trees, rather than the fir trees that we use today, and most of us will still have some Holly in the house at this time of year, even if it’s only in the form of a plastic sprig on top of the Christmas pudding. In England, there is a tradition of growing it close to the house to protect those inside from evil spirits, whilst in Ireland it is grown away from the house so as not to disturb the fairies that live in it. It is also said to deter lightning, and so alcohol vendors would set up their stalls under Holly at markets, hence the large number of pub names that include a reference to Holly.

Holly is one of the few plants that survives deep in the uncoppiced parts of Coldfall Wood, where it is too dark for other vegetation to thrive. For thousands of years, many different species of Holly grew in a habitat known as the Laurel Forest, which was wet and dark, and which covered most of Europe. However, as the climate dried out only Ilex Aquifolium, the plant that we know as Holly, survived and prospered in the new Oak and Beech forests. Most of the Laurel Forests had died out by the end of the Pleistocene, ten thousand years ago.

The plant above was the first one that I’ve ever seen in flower, and led me to think about Holly reproduction. Although the plant is often associated in folklore with the male principle (as opposed to Ivy, which represents the female principle), the flowers can be either male or female. A female plant will need pollen from a male plant in order to produce the berries. What puzzles me a little is that the flowers are meant to be produced in May, when there are pollinators about, but my photograph was taken on the sixteenth of December. I suspect this is yet another sign of the confusion that climate change is creating in the natural world, much like the snowdrops that I saw in full bloom a few weeks ago, or the crocuses already flowering in a neighbour’s garden. Without bees to carry the pollen, these flowers are doomed to blush and fade, unconsummated. There is an old tradition of putting a sprig of Holly berries onto a beehive on Christmas Day to wish the bees ‘Merry Christmas’. Who would have dreamed that it would be equally possible to adorn it with a sprig of Holly flowers?

Gulls Crows Holly Coldfall Wood 003The berries contain three to four seeds, each of which takes two to three years to germinate. Holly is a plant which grows slowly – it doesn’t start to flower until it’s over four years old (sometimes as old as twelve), and an individual shrub can live to be five hundred years old. A mature Holly can be ten metres tall, but most are much smaller than this.

Gulls Crows Holly Coldfall Wood 006What a boon to wildlife Holly is! My parents have a mature Holly tree which is about six metres tall, and at the slightest sign of trouble all the local sparrows fly into it, turning it into a mass of chirping. The spines on the leaves require quite a lot of energy for the plant to produce, so, as it grows above the level of grazing creatures the leaves become smoother. Ironically, Holly was cultivated as fodder for cows and sheep until the eighteenth century, and the smoother leaves at the top of the tree were obviously preferred, so it seems as if there was no escape from being gobbled up.

There is an old tradition that if Holly foliage is brought into the house, both the ‘He-Holly’ (the prickly leaves) and the ‘She-Holly’ (the smooth leaves) must arrive at the same time, otherwise the partner whose leaves are brought in first will dominate for the rest of the year. There is also a tradition that bad luck will come down the chimney on Christmas Eve if the Holly is hung up before the Mistletoe (who presumably takes offence). I have a big box of Holly and Mistletoe in the shed, awaiting the arrival of my mother so that we can decorate together. Who knew that it was going to be such a complicated business? At least all the leaves and the two species will arrive together, so hopefully we’ll avoid upsetting anyone.

IMG_0574

See how the leaves here are becoming less spikey than those in the previous pictures.

The ‘berries’ of the Holly (technically Drupes for my botanist friends) are very tough and bitter early on in the year. However, they are softened by the frosts, and become more palatable to the many birds and rodents that eat them, and by doing so help to spread the seeds through the forest. I put some Holly berries on the bird table, and they were gone by the following morning, so this might be a good use of any Holly decoration that is still in good condition by Twelfth Night.

IMG_0570Holly is one of the ‘original’ plants of the British Isles, with a history longer than that of human habitation here. It is no wonder that such a wealth of folklore and traditions have grown up around it. Its shiny, evergreen leaves and blood-red berries do seem to be holding the secret of life during these short, dark days, and it stands as protector and food-source to so many small birds and shy rodents. In winter-time, the Holly really is a kind of king.

For this post, I am grateful to the wonderful Poison Garden website, and to Plant Lives, another source of endless fascination. And I am eternally grateful to Richard Mabey for Flora Britannica, surely the most informative text on the folklore and traditions of British plants ever compiled.

The Twelve Days of Christmas..Can You Guess?

Firstly, a merry Christmas to all my readers who celebrate the day – for those who don’t, I hope that you have a peaceful break, and a happy and healthy 2024. Fingers crossed that some good things will happen in this leap year.

And for those of you who are up to your armpits in the last Christmas preparations on this Christmas Eve, I hope that you have some time to rest and relax and watch something silly on the television with a glass of something beside you, and your Christmas hat on at a peculiar angle. I shall do this in honour of my Dad, who definitely knew how to appreciate Christmas.

I wrote a piece about Christmas in the middle of the first Covid lockdown in 2020, not long after losing my Dad, and people have mentioned that it helped them to feel less alone at this often difficult time of year, so I’m linking to it here.

Dad in 2017 (post nap, pre Gin and Tonic)

As regular readers will know,  I always like to do something special for the Twelve Days of Christmas – in the past we’ve looked at the famous song, done an Almanac, had various quizzes and have generally had a bit of fun. And since someone pointed out the Twelve Days of Christmas actually start on Christmas Day, from tomorrow we’ll have twelve themed days of Christmas-related fun. See if you can guess what the theme is, and it will start from tomorrow, Christmas Day.

Pansies are Going It Alone…

Field pansy (Viola arvensis) Photo By Ivar Leidus – Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=127273286

Dear Readers, you might have come across a story about this little plant in the press this week, and no wonder. Field pansies can be found across Europe, western Asia and North Africa, and normally they are pollinated by long-tongued bumblebees such as Bombus terrestris, the buff-tailed bumblebee. However, these bees have suffered a 33% decline in the regions of study (around Paris, France), and so scientists wondered if, and how, the plants were adapting.

Producing nectar is very expensive for a plant – it requires a lot of resources to generate all that sugar. Furthermore, the plant then has to attract the bees, by using petal shape and colour and perfume to advertise that there is food available. Insect pollination is the most precise way for the plant to pass on its genetic material, so if there are enough pollinators, it’s worth it. However, when there aren’t enough bees around, the plant has another strategy that can be deployed.

Pansies are capable of something called ‘selfing’ – self-pollination. In this case, the plant fertilises itself, so it doesn’t need a pollinator. Plants that adapt to doing this can reduce their nectar load, and they no longer need the flashy advertising signals (one reason why plants that are wind-pollinated, such as grasses, don’t bother with such a palaver). Scientists used something called resurrection ecology to look at populations of field pansy in the same locations in the past, and compared them to the plants of today. They found that today’s pansies are 27% more likely to be self-pollinating compared with the plants of only 30 years ago, and that the plants, as expected, have lost some of the characteristics that made them attractive to bees.

This is an extraordinary example of rapid evolution to meet changing conditions, but there is a sting in the tail. The problem with self-pollination is that the offspring are all clones of the parents. This is ok while the conditions that the plant grows in remain the same, but the great advantage of cross-pollination is that you get variation in each generation. Then, when some ghastly disease or drought or rainstorms or bitter cold appear, at least some of the youngsters will survive (hopefully). If everyone is identical, everyone could be wiped out.

The web of life is complicated. In a way, it’s great that pansies are capable of self-pollination (not all plants are), but it is likely to reduce the genetic diversity in those particular populations, making them more vulnerable, as we’ve seen. This feels like an important study, and I hope that it will be replicated in other places to see what’s going on. And yet, we continue to use neonicotinoid pesticides which have a devastating effect on bees, bumblebees in particular. Humans might be the most intelligent species on the planet, but we seem, unlike the pansies, to have no survival instincts whatsoever.

Rant over.

Nature’s Calendar – 16th to 21st December – Darkness and Light Hold Hands

Cold Dark Matter – An Exploded View by Cornelia Parker (1991)

A series following the 72 British mini-seasons of Nature’s Calendar by Kiera Chapman, Lulah Ellender, Rowan Jaines and Rebecca Warren.

Dear Readers, as you might have noticed I’m a day late with this one. However, unusually the winter solstice, the shortest day of the year, was at 3.27 a.m. this morning (not on  21st December) so I’m not too far out! From now on there will be a slow lengthening of the days in the Northern Hemisphere, and a slow shortening of the days in the Southern Hemisphere. I rather like the balance of this: one half of the planet becoming lighter, the other darker, until the summer solstice when the pattern reverses again. It feels as if whatever else is going on, the basic engine of the planet is still in place.

Light and darkness is the quintessence of shadow: the way that light passes through some things and not others can create the most extraordinary effects if you have the time to notice them. Cornelia Parker used shadow extensively in her installations, such as the exploded shed in the photo above – Parker got the army to blow up a garden shed, and then she painstakingly mapped where the individual parts had landed and put them all back together in the instants just after the dynamite went off. The shadows across the walls and floor and ceiling are an intrinsic part of the work, and it begs many questions. A moment has been frozen, but is this just after the explosion, or is the shed somehow in a process of being remade, put back together again?

There are often other questions that arise at this time of year, especially (I find) as I get older. Did I make the best use of the past twelve months? What would I do differently? Is there the right balance between being productive and being thoughtful? I am not a great fan of New Year’s Resolutions, maybe because so often I find that they centre on things that I’m planning to ‘do’ rather than  how I’m planning  to ‘be’. I have a suspicion that the ‘being’ should come first, and should gently direct the ‘doing’.

How would it be if I wanted to be ‘more creative’. Or ‘kinder’? Or ‘calmer’? Or ‘more enthusiastic’ (Lord help us)? Something to ponder on, for sure. This seems to open things up in my head, rather than close things down.

So often, resolutions around ‘doing’ imply that there is something quintessentially wrong with us (too fat, too lazy, too stupid, too….boring). But resolutions around being seem to accept that we are a particular way already, and we just want to bring out more of our best features. I am creative already, but I could take up creative mending (quite a thing at the moment!). I am kind already, but there are lots of people in my community who could do with a helping hand, or a smile, or just a word of encouragement. I am calm already, but a bit of meditation wouldn’t hurt.

What do you think, Readers? I am a bit fed-up with resolving to do ten new things (Go to the gym three times a week! Read more literature in translation! Take up crochet!) and then feeling like a schmuck when I’ve dropped the lot by February. I suppose it’s about finding what really matters to us, and doing more of it, rather than trying to reshape ourselves as a whole new human being. Maybe we’re fine just as we are, and that’s a great starting point.

 

My Top Ten Unseen British Birds

Bearded Tit (Panurus biarmicus) Photo By Rob Zweers from Arnhem, Netherlands – Baardman – Panurus biarmicus, CC BY 2.0, https://commons.wikimedia.org/w/index.php?curid=75168667

Dear Readers, when I was writing about the hen harrier a few days ago, I mentioned that it would be in the top five of my list of British Birds that I’ve never seen but would love to see. Well, when I started thinking about it, I realised that five was definitely not enough, so here, for comment and debate, is my top ten of UK birds that I’ve never seen, but would love to see, in no particular order. First up would be the athletic and distinctive bearded tit/reedling. There was a rumour of one at the London Wetland Centre a few weeks ago, but alas I didn’t see it.

Next up is the firecrest. One of the UK’s smallest birds, along with the goldcrest, it is an unusual little jewel of a bird. There used to be a tiny population in Abney Cemetery in Stoke Newington of all places, and I suspect that they might be underreported – restless and hard to get a good look at, they are truly stunning birds. I might have to be patient though, as there are only an estimated 2000 territories in the whole of the UK, compared with 55,000 for the goldcrest.

Next up, the nightjar. So beautifully camouflaged, nocturnal, enormous eyes, and a reputation for stealing the milk from goats. I have seen nightjars in other countries, but never in the UK.

Next up is the ruff (Calidris pugnax) but I’m being a bit particular here, as I’d love to see them displaying on a lek: however, they are a Red List species, so I’m not sure whether you can see such a thing in the UK. I shall have to do some research.

And here’s a bird that I really want to hear as much as see – the turtle dove is such an iconic bird, mentioned as ubiquitous in Shakespeare and other writers of the period, but disappearing from our farmlands and woods during our watch. It’s great that places such as Knepp are working to recreate the habitat that they need, and that it seems to be working. As Kevin Costner said in that film about baseball that I can never remember the name of ‘If you build it, they will come’.

Then there’s the crossbill (Loxia curvirostra). Those amazing beaks are designed for extracting the seeds from pinecones. There are a lot of them about, but mainly in conifer forests, so I think I need a trip oop north. They remind me of little parrots.

There has been a noticeable absence of owls on my list so far, so here’s one: the long-eared owl (Asio otus). They aren’t that rare, but like most owls they are difficult to see. The ‘ears’ aren’t ears at all, but ear tufts, and nobody really seems to know what their purpose is, though most biologists suspect that they allow the owl to communicate its emotions and intent.

And while we’re on the subject of carnivorous birds, there are many, many birds of prey that I’ve never seen, but I would love to see this smallish bird, the hobby – it is a specialist in dragonflies and swallows, which means that it is quite the acrobat. It’s a summer migrant, so the window for seeing one is quite short. I may have glimpsed one in St Pancras and Islington Cemetery hawking for dragonflies a few years ago, but it wasn’t clear enough to be sure, so it stays on the list. Also, look at those red ‘trousers’! What a bird…

Eurasian hobby (Falco subbuteo) Photo By Shantanu Kuveskar – Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=111860073

Two to go (thinking about it, I’m going to make it a list of eleven birds to include the hen harrier that Ive mentioned already).

Number nine is the Great Northern Diver (Gavia immer). This is a bird of isolated lochs and lakes, and is perhaps best known for its evocative cry. It can crop up in practically any coastal area in the UK during the winter, so keep your eyes peeled! Have a listen to the recording by Yoann Blanchon below.

I realise that I could easily have chosen twenty birds, or even thirty, but here’s my last one for now. The Common Crane (Grus grus) breeds in Norfolk, and there is a small re-introduced population in Somerset. Birds can crop up in other places too, but they are vanishingly rare, with only about 30 pairs of birds breeding, and a maximum of 200 spending the winter in the UK. But my goodness, what impressive birds they are! The call is pretty impressive too. Have a listen to this splendid duet, recorded in Sweden by Esperenza Poveda.

And so there we go. Is there a bird that has always eluded you? A species that you’ve always wanted to see? A bird that turned up unexpectedly and took your breath away? Do share!

Wednesday Weed – Mahonia Updated

Dear Readers, you might remember that I have been puzzled about the plant in the photo above for some time. It was planted in the woodland graveyard in St Pancras and Islington Cemetery, and it seemed rather out of place. However, earlier this week we went for a walk, and all has been revealed….

It’s only a bloomin’ Mahonia! (literally)

There are seventy species of Mahonia, but I am most familiar with the spikey little number that I have in the garden (which I think is Berberis aquifolium, originally called Mahonia aquifolium but there is some debate amongst botanists as to whether the Mahonias should have their own genus or be lumped in with the rest of the Berberis). Aquifolium means ‘spikey-leaved’ – holly is known as Ilex aquifolium for the same reason). However, the ones in the cemetery are much more delicate and user-friendly, though if you look closely at the photo above you can see that some of the leaves are desperately trying to be at least a little bit dangerous.

I think this could possibly be Mahonia/Berberis Eurybracteata ‘Soft Caress’ – if anyone has one, let me know what you think! This species originally came from China, and was first described in 1900, when it was known as Mahonia confusa. Well, it certainly confused me. If you have a look at the herbarium specimen in the Kew Gardens collection, you’ll see that the plant’s leaves are still fairly spikey, so the plant breeders have worked hard to make it so inoffensive.

Anyhow, I had lots to say about Mahonia back in 2016, but I didn’t have a poem. However, I found this one on the website of Fairacre Press, and I think it probably sums up what a walk through the woods with me can sometimes be like, though (hopefully) without the withering stare. The poem is by Nadia Kingsley, and the pamphlet that it comes from (‘A Year in Herbs’) sounds rather lovely, with a poem a month for a plant that’s important in herbal medicine. I think I might indulge. Mahonia is January’s poem.

On a wintry woodland walk

“That’s not a holly bush” she informs
“Look there – at its spears of yellow flowers.
And if you come back in a month or more – you’ll see
that its berries are blue, not red. “Did you know,” she adds,
“that the berries are actually edible? You can make wine, or brandy”.
“Is that why it’s called the Oregon Grape?” I ask. She’s impressed.
I’ve been googling the plant, behind her back,
as we walk one-by-one down the narrow wooded path,
and I now read out: “It’s part of the Barberry family.
Did you know”, I add, “that the leaves’ undersides are tartan?”
“That’s Burberry” she says, as she gives me such an icy look
it’d wither even the Mahonia aquifolium – which is, by the way, evergreen.

And now, let’s journey back to 2016.

Mahonia aquifolium

Mahonia aquifolium

Dear Readers, there is no doubt at all that Mahonia (or Oregon Grape as it is often known) is largely a plant of parks and gardens, but I found this individual right on the edge of Alexandra Park and the north London Parkland Walk, where it appeared to be making a break for freedom. It is originally a plant of North America, and is named after ‘the first nurseryman in America’, Bernard McMahon (1775-1816) who curated the plant collection of explorers Lewis and Clark. The plant arrived in the UK in 1823. By 1874 it could be found in the wild, and it is sometimes deliberately planted as cover for game birds (much as snowberry was). With its spiny evergreen leaves, yellow flowers and, later, its bloom-covered blue berries, it is one of those plants that has some interest in every season. It also seems to tolerate clay soil, and so there are some very fine examples of the plant in East Finchley.

IMG_5349The plant has a lot going for it as food for animals. It is recommended by many organisations as a food-source for early emerging bumblebee queens and solitary bees. The flowers have a rather pleasant smell too. The berries are liked by blackbirds and mistle thrushes. The leathery leaves are also, surprisingly, a food plant for moths such as the Bright Line Brown Eye (once again, I am in love with the names of moths) and the Peppered moth.

However, mahonia is not only food for visitors to the garden – the ‘grapes’ have been used as human food. In North America, many native tribes ate the berries raw, whilst some turned them into jams and jellies, and others dried them. Should you have a superabundance of mahonia in your garden and an urge to knock up some preserves, you can find all the details you need at the Backwoods Home website. However, as many tribes people only ate the berries as a last resort, we can maybe assume that, whilst a useful source of vitamins, they are not as palatable as you might hope.

The wood of mahonia is bright yellow, and produces a dye of the same colour, while the berries produce a purple one. Richard Mabey notes in Flora Britannica that one young boy used the juice from the ‘grapes’ as very convincing fake blood. One can only imagine how much the child’s mother appreciated his inventiveness.

IMG_5456Mahonia has also long been used for everything from gastritis to syphilis by the native peoples of North America, and  there have also been some promising recent studies into its use in the treatment of psoriasis. Indeed, much as I hate to publicise it,  mahonia medicine has even made the hallowed pages of the Femail section of the Daily Mail. Why it’s in the ‘Femail’ section goodness only knows. As far as I know, men get psoriasis too. But it’s probably just as well not to get me started on gender differentiation in the media. We could be here all day.

IMG_5454And there is one more thing to mention about mahonia. Some plants react when touched – the ‘Sensitive plant’ or mimosa is one example. We had one in a pot when we were children, and I remember how the poor plant would behave when we touched it, the individual leaves creeping together as if terrified and then the whole ‘branch’ collapsing . How we laughed, spawn of Satan that we were. Well, New Scientist reports that more than 100 species of plants have touch-sensitive stamen, and that mahonia is one of them. On the Digital Botanic Garden website, there are photos of the stamen contracting after being touched – the theory is that this helps to force pollen onto the legs of any visiting insects. This is a remarkably quick reaction, taking less than a second in warm weather. We often think of plants as being slow-moving organisms, but the more I learn about them, the more I realise that they are intensely reactive beings, responding to their environment with great rapidity when necessary. Let’s never underestimate our flora. They’re a lot more dynamic than we give them credit for.

As usual, I’d like to credit Richard Mabey’s ‘Flora Britannica’ and Sue Eland’s ‘Plant Lives‘ website for providing invaluable information.

Red List – Twenty Three – Hen Harrier

Dear Readers, of all the UK birds that I want to see and have never seen, the hen harrier is in the top five. A bird of moorlands, bogs, marshes and other wild, open country, it has seen a shocking decline in England and Scotland over the years, though it seems to be doing relatively well in Wales, where there are 40-60 breeding pairs. There are two main reasons for its decline. The first is forestry – many areas of lowland have been, and were, planted with Sitka spruce, destroying the habitat for these birds which, unusually for birds of prey, nest on the ground.

However, the main cause is human persecution. The clue is in the name:  hen harriers largely eat birds (with meadow pipits being a particular favourite), though they will also eat frogs, voles and  insects. Gamekeepers see them as being a danger to the red grouse on driven grouse moors in England and Scotland, and the mere presence of a hen harrier is believed to impact a day’s grouse shooting. Literally hundreds of these birds are illegally killed every year. English moors should provide habitat for more than 300 pairs of the species, but in some years none have bred at all. It appears that in some areas grouse shooting is only viable if the animals that prey on the grouse are killed, which in my view means that it isn’t viable at all. Raptor Persecution UK is keeping track of all the hen harriers and other birds of prey that simply ‘disappear’ close to grouse moors. Their latest report makes for grim reading.

Hen harriers are elegant birds who hunt by sight and by sound – note the owl-like facial disc in the photo of the female above, which helps to channel the tiny scurrying sounds of mice and voles. During the breeding season, the male will drop food to the brooding female, who will catch it in mid-air. Hen harriers practice polygyny, with the males mating with up to five females. This means that they have to catch an awful lot of meadow pipits and voles, and research in Orkney showed that the more food is available, the more mates a male will have.

In the winter hen harriers will roost communally (if there are enough of them), and birds from Scandinavia and northern Europe may be spotted on salt marshes and other coastal areas right around the UK and Ireland. There is a famous population on the Isle of Man, and, as previously mentioned, on Orkney.

Perhaps most extraordinary of all, though, is the ‘sky dance’ display that the male hen harrier performs to attract a mate. Twisting and tumbling in the air, almost out of control and then regaining control, this unfortunately also makes the male bird extremely obvious and vulnerable to those who would seek to eliminate it. But to watch the display is to see something unforgettable. Have a look at the video below, and you’ll see what I mean.

New Scientist – What Holds the Great Wall of China Together?

Dear Readers, New Scientist had a most fascinating article this week about how a ‘biocrust’ (a mixture of moss, lichen  and cyanobacteria) are helping to protect the Great Wall of China from erosion. This extraordinary structure was started in about 200 BC, and rebuilt many times. Today, less than 6 percent of the original wall is well-preserved, and much of it has vanished altogether.

Much of the wall was built with a mixture of soil and gravel, compacted together to create ‘rammed earth’. Scientist Bo Xiao and his team at the China Agricultural University in Beijing sampled a 600 kilometre section of the remaining wall, and found that more than two-thirds of it was covered in biocrust. Traditionally, such layers are removed (not just in China but in most sites of archaeological/historical interest), but the scientists found that the biocrust actually strengthened the wall, in addition to forming an insulator which helped to reduce the temperature extremes that the structure experiences.

The areas covered in biocrust were also less porous so there was less water-penetration, erosion and salinity. Interestingly, these sections of the Wall also showed increased resistance to mechanical assault. It seems that in some places this mixture of algae, moss and lichen is literally holding the wall together. What a shame that this protective vegetation is so often removed to improve the aesthetic value of a monument!

You can read the whole article here, and very interesting it is too.

Plus, I went for a walk in St Pancras and Islington Cemetery yesterday, and found lots of biocrusts – some kinds of headstones and memorials definitely attract more moss and algae than others, but I was particularly taken  by this little bit of retaining wall. There is clearly a whole mini-community going on here, and I’m very glad that no one has yet found the time to ‘tidy it up’.

There is a lot of scientific study into biocrusts going on at the moment, and many seem to indicate that they improve the drought-resistance of soil, and can help with bioremediation of ex-mining sites and other contaminated areas, and even in Arctic tundra areas where the biological community has been damaged by trampling. I expect we’ll hear a lot more about biocrusts in the future. Watch this space!

Sparrows!

Dear Readers, the garden has been visited regularly by house sparrows this winter – this morning I counted a flock of twelve. I couldn’t be happier! I’m not sure where they’re roosting (certainly not in my sparrow nest box, which I suspect is too low and too close to the house) but I’m always happy to see them wherever they turn up. And this week, Facebook reminded me that I’d actually had an article about sparrows in The Londonist  back in 2014, and if you’re inclined, you can  have a read here (titled ‘Where have London’s Sparrows Gone?)

This also reminds me that in February 2024 I’ll have been writing this blog for ten whole years! Surely that calls for some kind of celebration. I shall have to have a think, but do comment if you have any suggestions. I’m also 64 this year, so I’m expecting quite a lot of renditions of That Beatles Song….And because I love you all, here’s a version subtitled in Spanish. You’re welcome.

It’s not just sparrows in the garden, though: there is a very athletic little black and white cat, who is trying to catch either a squirrel or a pigeon but hasn’t cottoned on to the fact that you have to hide first, so everyone is on to her long before she makes her pounce. Let’s hope she doesn’t get wiser quickly.

The collared doves are chasing one another around a bit, almost as if it was spring. I saw a feral pigeon trotting up East Finchley High Road with a twig in its mouth earlier this week – pigeons and doves can breed all year round if there’s food about, which there certainly is. I was accosted on the doorstep by a fox this week too – it had clearly been planning to limbo dance under the door to my side return, where there’s quite a gap, but decided to wait until I’d gone. I love the way that they just sit there patiently, or melt into the undergrowth.

In spite of all your advice (thank you!) I haven’t quite gotten around to getting a squirrel-proof feeder yet, so the little devils are still eating me out of house and home. Maybe after Christmas I’ll get my act together.

And all the usual suspects are popping in – the goldfinches, the starlings, a pair of jackdaws (who have mastered the suet feeder), some occasional chaffinches, a dunnock, a wren, a robin who appears from nowhere when the mealworms come out. All in all it’s a busy time for the birds, and lack of leaves means that I can see them. It’s all about the dreaming and planning now, and the waiting for the bulbs to come up (though my husband did intercept a squirrel either digging something up or planting something in one of the pots in the front garden this morning). The world is turning, slowly but surely.

The Menace of Giant Rhubarb!

So what the hell is this then ? (Photo by Tom Oates.The original uploader was Nabokov at English Wikipedia. (a.k.a. Tom Oates) – Transferred from en.wikipedia to Commons by Kafuffle using CommonsHelper., CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=17669124)

Dear Readers, what a can of worms has been opened this week on the subject of Giant Rhubarb! Usually known as Gunnera, this plant has been a favourite of stately homes for many years. I briefly considered it for beside my pond, before realising that what I’d actually need was a lake about a hundred times bigger than my relative ‘puddle’. But a few days ago, Giant Rhubarb was declared an invasive species, and it is now forbidden to be sold or cultivated. What’s going on?

It was believed that there were two species of Gunnera in the UK. The first, Gunnera manicata, comes originally from coastal areas of Brazil, was believed to be a benign plant with enormous leaves and an  impressive flower stalk. It was widely sold, and I suspect that there are many, many parks with this plant spreading its mighty leaves beside the goldfish pon.

The second, Gunnera tinctoria, looks similar but is invasive. It’s been banned from sale in the UK since 2017, and has wreaked havoc in New Zealand.

Well, Readers, it appears that ‘the enemy’ has been hiding in plain sight. Scientists now believe that all the plants we’ve been thinking are the lovely Gunnera manicata are in fact hybrids: Gunnera manicata crossbred with Gunnera tinctoria very early on in the history of the plant in this country to produce Gunnera x cryptica. Gunnera x cryptica is extremely invasive (and is already causing problems in wetter areas such as the west of Ireland and Scotland). Furthermore, there are probably very few Gunnera manicata left, as the hybrid has outcompeted its less vigorous sibling.

In ‘Alien Plants’, Clive Stace and Michael Crawley have this to say:

On coastal cliffs, the main impacts of colonies of Giant-Rhubarb are the threat of erosion and the loss of maritime species. Apart from the ecological impacts associated with the loss of biodiversity, there are also landscape impacts, including the reduction in the area of land that is suitable for agriculture and amenity purposes. Dense stands of Giant-Rhubarb growth may also lead to the blockage of drainage channels and increased risk of flooding. Due to the size of the plant, access to sites infested with Giant-rhubarb is difficult, making control measures problematic’ (Pages 470-471)

What to do? DEFRA says that any existing plants can be kept, but no more can be planted, so there will be a flurry of activity in nurseries and garden centres up and down the country. For existing plants who have hopped over the fence, it’s probably down to cutting back and blitzing with herbicide, in much the same way as people are trying to deal with Japanese Knotweed. The plant also needs a lot of water, so is likely not to do well in drier areas.

Yet again, it seems that something imported for its dramatic appearance has turned out to be rather too fond of life outside the garden, with the added complication, in this case, of the plant turning out to not be what it seemed. I shall watch with interest to see what happens next.
