Bynack More rising above Abernethy Forest |
This article first appeared in The Great Outdoors a year ago. I've been thinking about rewilding, forests and land use recently and have had various discussions on social media sites on related topics so I thought I'd post it here.
How wild and natural should the hills be? Do you want them
tame and docile so the walking is easy and secure? I ask in response to an
online comment from a TGO Challenger who likes sheep in the hills because they
make walking 'very pleasant'. Now sheep-cropped grassland certainly is easy to
walk across but it's also an artificial and biologically degraded landscape.
Natural landscapes are wilder, more diverse and, for the walker, more
challenging. Where the terrain is impossibly tough - dense forest, tangled
bushes - the answer can be a path. I'd rather see a narrow trail through a wild
and natural landscape than sheep-cropped terrain where it's easy to walk
anywhere. And if there's no path then I'd rather find a way through the
difficulties than have them tamed.
Regenerating forest in Coire Ardair, Creag Meagaidh |
A bigger question is how to achieve more natural and diverse
wild lands. Just what does that involve anyway? Ideally I think it means
leaving land alone, leaving it to be 'self-willed'. However whilst that's fine
for pristine and near-pristine places it may not be for more damaged ones. The
question then becomes how much interference and management is acceptable. In
turn this raises the question of how long you want to wait and whether the
rewilding of a landscape can be speeded up. The answers vary depending on your
outlook and aims. Aesthetically I think any management should be as unobtrusive
and unnoticeable as possible. I also think such management also produces a more
natural landscape in the long run. However I accept that in some places it just
isn't possible, at least at present.
Recently I was in Eskdale in the Lake
District where some extensive tree planting is being undertaken by
the National Trust. Because this is sheep country the planted areas are fenced
and the trees are caged. This looks highly unnatural. In time I guess the cages
and fences will be removed and the forest will look more natural though it will
still have straight lines dividing it from the bare land outside it. Less
obtrusive is the work being done by Trees for Life in Glen Affric. Again
planting is involved but the trees are not caged. The new forests are simply
fenced in to keep out deer. Again the line between the rich vegetation inside
the fence and the sparse boggy vegetation outside it is stark.
Scattered pines at the edge of Abernethy Forest |
Contrast these schemes, both of which I support, with that
of the RSPB in Abernethy in the Cairngorms, a huge reserve that stretches from
the forests around Loch Garten of ospreys fame to the summit of Ben Macdui.
Having heard that the RSPB was to plant areas that as far as I knew were
already regenerating and pretty natural anyway I contacted the RSPB to find out
what was going on and was invited on a field trip so I could see for myself
(thanks to Regional Director George Campbell for organising this and also to
Senior Site Manager Jeremy Roberts and Ecologist Andy Amphlett). Before we
headed out to look at the area the scheme was explained and I was shown
detailed maps of the forest divided into different types of area. No planting
was going on in the mature natural forest or in areas where there was good
regeneration I was told. Overgrazing isn't a problem in Abernethy now as deer
numbers have been reduced and sheep removed. However there is a wide band of
higher ground where the sheep used to graze that runs up to what should be the
natural treeline of 650 metres where there are no trees at all and so no seed
source for regeneration. There are also areas of previously felled and then
planted forest where many tree species are absent. It's in these areas that the
RSPB is planting small groups of trees to provide a seed source. The planted
areas won't be extensive, just small clumps, and there will be no cages or
fences.
New growth in Abernethy Forest |
Out in the field I
was shown some aspen that had been planted on some heather moorland. I would
never have know they weren't the product of natural regeneration. Higher up we
found the last tiny pines, still well before the 650 metre line. It was clear
that there would be no natural regeneration here for a very long time. The RSPB
has set a 200 year goal for the return of the forest so even with the planting
it will take a long time. For walkers there will be no discernable sign of this
management, unlike in Eskdale and Glen Affric. That's because the RSPB owns the
land and has control of grazing, which takes us back to the start of this piece
and the question of what sort of landscape we want. For myself the idea of the
returning forest is exciting and unspiring. I'll only see it beginning but that
is a joy in itself.
