What protection do pine martens have?
Pine martens are listed under Schedule 5 of the Wildlife and Countryside Act (1981) which means that it is illegal to intentionally kill or injure pine martens, or disturb their dens. Any research that could disturb pine martens, such as trapping animals or monitoring den boxes, must be done under a licence from the necessary statutory body (Natural England if in England or Countryside Council for Wales if in Wales).
