Woodland Watch – Week 12 – 05/06/2013

This week, I decided to focus on the coppice. There’s such a lot going on in the woodland at the moment now that the weather has finally warmed up, but over the last 11 weeks we have takes a lot about the “coppice woodland” and never really elaborated on what this means.

So, here we go. Lets go for a walk in the woods and take a look at one of the earliest forms of woodland management.

Coppicing is a traditional method of woodland management which takes advantage of the fact that many trees produce new growth from the stump or roots if they are cut down. Coppice stools have multiple stems growing out of previously cut stools which arise from dormant buds on the stool. The resulting structure looks like this.

Most frequently coppiced species are oak, hazel, ash, willow, field maple and sweet chestnut. In this woodland, most of the coppice is hazel but management has lapsed and many of the stools are in need of management to bring them back into the coppice cycle.

Stools such as this one have been allowed to regrow for too long.

Coppicing allows for the production of a large quantity of fast growing, sustainable timber products without the need for replanting. Although trees can be grown from seed, coppicing allows the tree to regrow from a fully established root system.

Different species respond differently to coppicing. Some species such as alder and beech coppice poorly, while species such as hazel and willow respond very well, quickly sending up vigorous, straight growth which can be utilised in a range of ways.

Most notable in this woodland is the way that the coppice affects the general feel of the woodland area. In traditional broad leaf woodland, the canopy is usually quite high and the understorey more sparse than in a coppice woodland. Here, especially now that the leaves are out, there is much more vegetation at eye level than you would usually find in non-coppiced woodlands.

We have said before that the structure of this woodland is “coppice with standards”. This means that there is a coppice understorey with scattered larger standard trees. These standards need to be sufficiently spaced apart to avoid shading the coppice.

The standards in this woodland are primarily oak and horse chestnut, however in some areas these trees have been allowed to grow too large and too close together and the coppice understorey has disappeared, out competed and overshadowed by the larger standards.

Hopefully, some of these lapsed coppice stools can be brought back into a coppice cycle in the near future.
