Pine martens need neighbours but like to keep their distance, according to new research.
Over three years, the cat-like predators were caught in Scotland and moved to mid-Wales by Vincent Wildlife Trust.
By attaching miniaturised radio-transmitter collars to 39 of the released animals, a tracking team followed them for a year as they explored their new home in Welsh forests.
The research, published today in the journal Ecology and Evolution, was carried out by Dr Cat McNicol from the Environment and Sustainability Institute of the University of Exeter with staff from Vincent Wildlife Trust. MORE
