For a long time the lower slopes of the Skirrid on the outskirts of Abergavenny have been wooded, long enough for it to be classed as ancient woodland. Features found within the wood and its presence on some of the oldest mapping confirms this. The wood's species and appearance went through quite a change in the middle of the last century, as a lot did, in the push to grow our own timber through the drive for conifer plantations.
Winding back the clock
Over the last 30 years we have been working to wind the clock back. Reducing the conifer numbers has been a key part of this, but waiting for them to reach maturity for market has also helped fund our work alongside woodland schemes and membership support.
Where conifers were removed in the early phases of work, we have had a fantastic dense regeneration of the species we would expect to find in ancient woodland. It is great that so many of these trees have come from the seed source that lies in the soil, typical of ancient woodland, however, they are little better than the conifers for the woodland's diversity. The regrowth is all the same age, the same size and creates a thick canopy that shades the woodland floor.
What we have done
This is why we have begun thinning through the woodland. Focusing on a section at a time, we are taking out around 30% of the trees, possibly a little more in the planted beech sections that are really hampering the ancient woodland's regeneration. This is creating canopy gaps for light to reach the woodland floor to help improve regeneration that includes everything from the smallest plants up. Some of our work has already allowed bluebells, a fantastic ancient woodland indicator species, to show through where they haven’t previously. The thinning also breaks up the age and size of the trees and allows us to give space to those we feel are important to the wood. These might be mature trees that can provide the future seed source, veterans or less common species that are present on the site like hornbeam or elm.
