Red Deer

About the Red Deer

The Red Deer (Cervus elaphus) is the largest wild land mammal in Britain and one of the largest deer species in the world. Stags can weigh over 200 kg and carry antlers with 12 or more points — the classic 'royal' stag that has stared out of Scottish paintings for two centuries.

Red Deer are found across Europe, the Caucasus, Iran, western Asia and, thanks to introductions, parts of Australia, New Zealand and Argentina. Their British stronghold is the Scottish Highlands and, more recently, Richmond Park on the edge of London.

Habitat & range

Red Deer are woodland animals that adapted to open moorland after their native forests were cleared. They now thrive in mixed woodland, upland moors, farmland edges and large parks. In summer they favour high ground; in winter they drop into sheltered valleys.

A herd needs continuous habitat over tens of square kilometres, which makes them highly sensitive to fencing, roads and wind-farm access tracks.

Diet

Red Deer are grazers and browsers, feeding on grasses, sedges, heather, tree shoots, bark and, in autumn, fallen acorns and beech mast. In hard winters they will strip conifer bark, which puts them into conflict with commercial forestry.

Behaviour & life cycle

Red Deer live in single-sex herds for most of the year. In September–October the rut brings the sexes together: mature stags roar to advertise their dominance, gather harems of hinds, and clash antlers with rivals. The roar of a Red Deer stag can be heard three kilometres away on a still autumn night.

Calves are born in June, spotted for camouflage, and hidden in bracken while the mother feeds nearby. Antlers are shed each spring and regrown in months — the fastest growing tissue in the animal kingdom.

Main threats

Red Deer are Least Concern globally, but in the UK there are separate problems in both directions: local overpopulation in the absence of natural predators damages young forests and rare habitats, while illegal poaching, road collisions and loss of migration corridors threaten them elsewhere.
