Marten Masterclass: 3. Pine marten den sites 

Here at GWT we are supporting the recovery of pine martens in the UK by reintroducing this native species to the Forest of Dean and Lower Wye Valley.
The ongoing monitoring of this recovering population is only possible with the support of volunteers.
Project Pine Marten is bringing you a series of Marten Masterclasses which will cover pine marten ecology and ways help us monitor their progress in the region.
This is the third of 6 short Masterclasses focussing on pine marten den sites: where do pine martens den? what do den boxes look like? how do we monitor den sites?
In case you missed them, here is the link to Masterclass 1: • Marten Masterclass: 1...
