How Deep is your Bog?

An event organised by Galloway Glens Landscape Partnership offered a glimpse of the plants which create the depth and the breadth of Beggar’s Moss. The partnership intends to restore this rich Moss, which is fascinating culturally as well as ecologically.

At the end of August last summer, Emily Taylor  led an event for the Galloway Glens Landscape Partnership to Beggar’s Moss in New Galloway Forest Park. This attracted a group of bog aficionados and had all the feel of an expedition.

Beware! It is easy to get lost amidst the Forestry Commission conifers around the bog. The awkward access was all the more exciting for those carrying peat probes and other survey equipment. I was glad that the sandwiches made it through unscathed.

We created a marker point for our basecamp, on the ‘shore’ of the Moss.

Beggar’s Moss is a peaty island left within the extensive afforestation of this area that took place in the 1950s and 1960s. The Moss triumphed as it was too wet to plant. Being protected from grazing by the plantation, the Moss has become ever more verdant – with colourful Sphagnum mosses mixed amongst other plants.

Emily’s guidance helped understand something of the environmental contexts that led to the luxurious depth of the bog, and also the plant profile of its living layer that gives it a fascinating breadth. We learned to survey a line of quadrats, showing the plant transitions across the Moss. It took me a long time to tell the difference between deer grass and cotton grass, but expert eyes made it look simple to identify the intriguing bog plants.

At the same time, others in the party probed the peat and found it was 8 metres deep.

We discussed the impact of our footprints on the living surface layer. Perhaps wellies do more damage than bare feet?

Sundew plants growing between the mosses were the stars of the day.

Lodgepole seedlings are menacing because when they grow, these trees’ deep roots can crack the bog. Some seedlings were uprooted exposing their long taproot – perhaps this was the start of a process of restoration.

At lunchtime, eating sandwiches kindly provided by Galloway Glens, we discussed the Moss’s changing fortunes and the irony of our introduction of olive pits to its plant record. I intend to keep track of the restoration of Beggars Moss, and to learn more of the plants that made the bog a wonderful eight metres deep.

Thanks to Emily Taylor and McNabb Laurie for creating this public event, which was part of the Galloway Glens programme.

couldn’t make a sandwich out of that

A visit to the Natural History Museum in London to see the Hummingbird Cabinet

As I drew, I found passers-by were echoing my own reflections. There was much curiousity about these stilled birds, some of which may now be extinct.

they are all real but they are dead… look at these – yes I seen them before … they are all diferent! yeah, that’s what he collected … I LOVE that one … birds after birds after birds after …

teeny weeny birds … look at the nests! … so many of them … superbe!

I was not the only person to crane my neck to look into the case – looking at tiny nests with nestlings, the fine crests and flashes of remaining iridescence from these two hundred year-old birds.

someone just killed a load of hummingbirds … oh my goodness, the size of them, they are tiny! they are all hummingbirds! … as small as butterflies … I feel ever so sorry for those birds … this one is disturbing I have to say .. do you remember this? I came to see it fifty years ago … I don’t know if that is amazing or disgusting … well it’s old isn’t it, a different time … I wonder what colour that would have been when he first saw them … you can see why they put them in hats, can’t you? …

you couldn’t make a sandwich out of that  couldya?

I took a break, for lunch.

Walking up the track in a stretch of euroforest, I start to take in the extent of storm damage

It is staggering, but we are adjusting to the hill’s new shape.

The western section was systematically felled last spring; last month it was moulded into lines, drains and brash-heaps ready for re-planting. The heavy machinery and oil-lorries have left their tracks and laid bare the earth again. The river became full of silt in the heavy rain.

In taking its crop of trees last year, euroforest exposed stands that had been protected. The series of storms over the winter took their toll and the most recent hurricane in January has left a wake.

It is hard to make sense of it: roots in the air, some trunks snapped and still vertical, others lying horizontal. Many, many hectares of damage.

I want to go in and have a closer look: it is a jungle, I need a machete. I cannot get through.

Getting as far as I can, details become apparent. My mind makes some kind of pattern of things. No such thing as a balance of nature – this is a temporary rearrangement.

The new territory is more accessible to others, who are taking advantage of its possibilities.

A pair of crossbills come over – checking me out? Warning me off? Red male, green female; they look around and then start to strip bark. Perhaps they are nesting. I move too suddenly, they fly off.

I walk on – listening out, I become aware that I move through the forest with a bow-wave of avian alarm calls.

“Populus tremula, Tweedsmuir”

Last week, I took a couple of aspen cuttings to Dundee Botanical Gardens. They will spend a year or two in the nursery of the Native Plant Communities Unit (see http://www.dundee.ac.uk/botanic/garden/collections/)

Their new labels announced them: Populus tremula Tweedsmuir.

They will add genetic diversity to the collection, and are two of the eight I produced after collecting roots on the A701 (see  https://inthepresenttense.net/2011/03/15/plantcollecting-on-the-a701/)

Specimen 19760128DA in the Native Garden also has expansion plans. I map out lines of runners and ramets radiating from his/her diamond marked trunk:

The ramets confusingly do not necessarily have aspen-shaped leaves. At their tops, closest to the light, the leaves are largest and pointed with round stems – no quaking here.

Indeed, a determined advance by 19760128DA, who is using the right to roam.

summary of project at Over Phawhope Bothy, Ettrick Valley, Southern Upland Way

… the right to enter on to, roam on and pass over open country …

Aspens grew on me, as a wild presence exercising their right to roam. Aspen trees are fragments of the wildwood that extended across Scotland after the ice age. Thinly scattered, you may find a few remaining aspen stands in the southern uplands – in cleuchs beyond the reach of sheep’s teeth, or possibly surrounded by spruce plantation in dispirited clumps. Present in larger numbers, they can support a varied ecology. In leaf, aspens can be recognised by the way their thin-stemmed leaves shimmer and turn yellow in autumn.

I learnt to recognise aspens in winter habit, locating the nearest ones to Over Phawhope Bothy.  I was taught to propagate them by encouraging them to form suckers  – in the wild they spread themselves as clones, commandeering what space they can.  A stand of aspen is likely to be very ancient, yet comprised of young trees that defeat death by sending runners.

… the separation of individual ramets, or daughter plants, occurs by the death of intervening connections, known as stolons or runners…

Near Over Phawhope Bothy, you can find two new young saplings that I planted and will keep an eye on until they are established.  In time, their movement and colour can enliven the line of conifers that cast a dark tone behind them. Perhaps with more time, aspen may provide avenues of growth within a changing climate.

The photo above is of aspen in a protected cleuch in Moffatdale – some of the closest wild trees to Over Phawhope Bothy  (taken in March 2011).

plant-collecting on the A701

I travel many miles looking for aspen. No Populus tremula at Dawyck Botanic Gardens (a kind of Tree Zoo). Down the A701: a grove by the side of the road.

I have permission to take a root cutting, but no-one to tell me which tree. Check the ID book: yes, it has diamond marks on its bark.

and sharp-ended leaf buds on brown stems:

Ok, dig. Looking for thick roots – just find strings. Wrongly assume need to dig deeper. My spade too big and too blunt. Lots of stones. A personable man and his son stop in a big green 4×4 to check I am not burying a body. Eventually work out that the roots get thicker and nearer the surface as you get away from the main stem. Find a wee sucker and that is where I find a finger-sized root. Use hands to pull it out together with a big pair of choppers, glad I brought them along.

Aspen grow on me, a wild presence, self-cloning their way along the burn.

I read later why I had to move away from the tree to find a runner – aspens defeat death with death:

Each of the morphological structures known as rhizome, stolon, runner [&c] undergo vegetative multiplication by death and decay of old tissue … Death of the stolon or runner separates these rooted and now independent daughter plants, each of which is termed a ramet.  The ramets produced from one parent collectively form a genet or clone. (Plant Form, written by A Bell, drawn by A Bryan, p 206.)

Aspens quietly suckering their way as they can, commandeering space in the few corners they have left.

Fragments of this genet now sectioned, sandwiched with No 3 John Innes, set at 18 degrees C in a propagator.

Rhizomatic action seems to assume a rather purposeful and linear form, when biotic survival is concerned.

This particular aspen grove cannot be sure of its survival, I am told by its manager – too close to a planned access road for wind turbines.  So now, what are now more numerous, wind turbines or aspens? I am also told that a wind turbine has vast concrete roots.  I’d like to chip away at that too, and propagate a tiddler, on a community scale.

Proposal: planting an aspen at Over Phawhope, Ettrick Head

This post is about the practicality of planting an aspen.
The context: 2011 is International Year of Forests. An initiative of the Forest Bookstore in Selkirk has led to a group project – installations at a site in the ancient Ettrick Forest, at the head of the Ettrick Valley in Over Phawhope.
‘Phawhope’ might mean variegated valley / the valley of different colours:
The shelter is maintained by the Mountain Bothy Association. It is surrounded in the main by sitka spruce plantation, portions of which have recently been clearfelled. The bothy has sheep grazing immediately next to it, along the valley. The ground is rough and waterlogged.
Apart from the dominant spruce, there has been other tree-planting. A conifer (noble fir?) stands by the bothy.  The river edge has been planted by Tweed Foundation as an effort to preserve riverine habitat – perhaps eight trees, at most 2.5 metres high – a mixture of hazel (?) and birch. Some grow reasonably – a few been axed (for the bothy fire?)
Closest to the bothy, starting at the tall fir, there is a line of six trees: birch, hazel (?) and ash extending along the west of the bothy (along the wall  on the right of the photo above). The first (closest to the fir) has been axed. The second is dead:
The third tree in line (whch would be it’s neighbour) is best established – a hazel? Then three ashes follow, nibbled to three different degrees:
My proposal is to plant a sapling in the space between these two dead trees (next to the fir) and to keep check on its progress until it is established.
Why? The project is about biodiversity and exchange. A broadleaf tree would in some way assist biodiversity in Ettrick Head (albeit at a symbolic level). The exchange element is about carbon dioxide. It would offer Southern Upland Way walkers a growing resource (at a point in time when the Way landscape is changing due to commercial plantation and windfarms). To plant a tree is a way to look forward (at a time when we are forced to adapt to inevitable climate change and accelerating biodiversity loss). This will coincide with a publication by Reforesting Scotland with specific advice and information about trees and planting. I will also provide 2D work in or near the bothy developing visually some aspect of the tree in its context.

I will plant the sapling in April 2011. The materials budget for my part of this project stretches to £85. I aim to use local expertise and suppliers.
Aspen?

This choice is informed by current advocacy of aspen by various conservation groups in Scotland. Visually, their shimmering movement will add liveliness to the backdrop of still spruce. Their thin-stemmed leaves play in the wind, incredibly holding on to the branch. They have a vibrant yellow leaf in autumn. From a biodiversity point of view, the invertebrate populations associated with aspen copses are well studied, and considered important by entomologists. In Scotland, aspen plays a role in the regeneration and restoration of woodland and is also it is envisaged that it can play a role in commercial forests as the value of its wood is reconsidered.
Comments to date (many thanks for these):

• from an entomological viewpoint: the presence of aspen does not mean associated invertebrates will be present – it is a widely distributed tree but the range of associated fauna only occur when there are stands of it. Single trees will not attract a density of species. Some invertebrate species need fallen trees, standing in particular ways and on a large scale. Aspen stands have been studied in the Highlands – see Malloch Society Research Report No1, the Entomological Value of Aspen inthe Scottish Highlands. Also see proceedings of a conference on the Biodiversity and Management of Aspen Woodlands published via SNH in 2002.
• the photograph of the nibbled tree within the tree guard looks like deer damage. This means I need a higher tree guard. I read that apsen are particularly attractive to herbivores. (I wonder what measures are taken in the forest to prevent deer damage?
• The idea of wolves at Ettrick head is intriguing – they have been called ‘painters of hills’ by Jim Crumley because they cut back herbivore grazing and allow different plant grwoth.  There is also an association of beavers with aspen.
When was the last wolf, the last beaver, seen at Phawhope?
• advice on its likely growth: “I would guess it would grow about one foot per year depending on soil and climate. It looks a wind swept situation, which could limit growth. Aspen spreads by suckering which makes it  unpopular in foresry since it takes nutrients from the profitable trees. In your situation it  would produce suckers around it every summer, but these would be browsed down by sheep and deer in the winter, and so would be no problem in the wider landscape. If the aspen was in an enclosed garden with other plants you might need to prune off the suckers each year.”
• How to produce aspen seeding (I should have started a year ago). They hardly ever seed. So you have to propagate them from root cuttings. At the beginning of March, dig up a root about half an inch to an inch circumference. Any length. Be careful not to bruise them, cut off any bruised bits if necessary. Put the root into medium, propagate, and after two weeks, they shoot. When the shoots are two inches high, cut them with a craft knife. Plant them into perlite and vermiculite, and leave another fortnight to root. Prick them out into compost, and keep them in a greenhouse till mid June. Keep in a pot till the next year.
• Plant on bare earth (clear away the grass) and put up what tree guards are necessary for the site. If deer are present, you need a high-sided guard. Rabbits need to be kept out with wire. Voles need a vole guard. Check the tree at the start of the growing season and in autumn for a couple of years. Play it by ear when to remove the tree guards, could be needed for several years.
More practical questions:

• What is the best robust design for a tree guard? (best to avoid wood as it will be tempting fodder for the bothy fire?)
•  What would it need protecting it from?
• Would it be good to feed / manure / mulch the sapling?
• Would any record of planting in Phawhope be available?
• Is there any cahnce of this in actuality increasing invertebrate biodiversity? What would that require?
