Sika deer
Deer are common at Ben Wyvis, with red deer in particular being frequently seen. Sika deer can be occasionally spotted at the edges of the woodland that fringe the area, with roe deer also preferring the cover of the forest. Other mammals at Ben Wyvis include mountain hare on the open slopes, and pine marten in the woodland. Deer numbers are managed via an annual cull in order to reduce grazing pressures on vegetation. Culling at Ben Wyvis is undertaken by a leaseholder, who rents the deer stalking rights from NatureScot.
