What work will take place?

In the coming weeks, forest operations are expected to begin in Pant y Warren forest near Devauden, Monmouthshire, to thin the conifer crops and will take about six months to complete.

The work is part of a wider effort to restore and improve the health of the woodland following the disruption caused by the larch disease outbreak. The thinning will:

  • open the canopy to encourage natural regeneration.
  • improve the stability and resilience of the remaining tree crops.
  • support the restoration of ancient woodland.

Access and Footpath Closures
Public Rights of Way will be officially closed during the operation period. However, we will make every effort to keep as many footpaths open as possible. Closures will be temporary and limited to active work zones, reopening as operations progress.

Safety
During the work, please follow all signage and safety instructions and be aware of timber wagon movements on forest roads.

Why do we thin trees?

Once an area of trees has matured to a certain size, they begin to compete with one another for nutrients, water, and light.

Thinning the trees helps to reduce this competition and allows us to remove unhealthy trees and those that are not growing well. It also encourages natural regeneration of native species and helps restore our ancient woodlands.

This is one of the most beneficial activities that can be done for a growing forest and is a vital part of the forest cycle.
