The question of territoriality in roe deer is a knotty one, depending to a great extent on the habitat and population pressures in surrounding woodland.

If one assumes that home range is the area occupied by an animal, but that territory is an actively defended area, most research states the doe is only territorial around the time of the birth of her offspring, and this territory must be some distance from her normal home range.

A buck, however, is territorial under most conditions from March to October. He may stray, either to test his neighbour’s boundaries, to discover a better territory or in search of does during the rut.

Research at Kalo, in Denmark, showed a population could be shot out with little recolonisation, but that was in a district of high shooting pressure and, consequently, low peripheral density.

If the surrounding land is under-shot there will be a high element of influx.
