England’s landscape supports six distinct deer species, a unique blend of ancient inhabitants and animals introduced over centuries. This population, the largest number of deer species in any European country, consists of two native species and four established non-native imports. Each species has successfully adapted to the British environment, creating a complex ecological picture.
England’s Native Deer
The two species considered indigenous to England are the Red Deer and the Roe Deer, both present since before the Mesolithic period. The Red Deer (Cervus elaphus) is the United Kingdom’s largest land mammal. A mature male, or stag, stands up to 1.37 meters at the shoulder and can weigh up to 200 kilograms. Stags develop multi-tined branching antlers that are shed and regrown annually, becoming more elaborate with age. This species is most commonly found in moorlands, open uplands, and extensive woodlands, with notable populations in Exmoor and the Lake District.
The Roe Deer (Capreolus capreolus) is significantly smaller and much more widespread, often seen in woodlands, scrub, and agricultural land. They possess a reddish-brown coat in summer that fades to a greyer tone in winter, and they have a distinct white rump patch but no visible tail. The males, called bucks, grow short, upright antlers that typically have no more than three points. Roe deer exhibit embryonic diapause, where the fertilized egg delays development until late winter, ensuring the young are born in late spring.
The Widespread Introduced Species
The Fallow Deer and the Sika Deer are non-native species that are now considered naturalized. Fallow Deer (Dama dama) were first introduced by the Romans, though the modern population stems from reintroductions prior to the Norman conquest. They are medium to large deer, recognizable by their typically tan coats with white spots in summer. Males have distinctive palmate, or palm-shaped, antlers, and they form large herds that thrive in parklands and broadleaved woodlands.
The Sika Deer (Cervus nippon) is a medium-sized species native to eastern Asia, introduced to deer parks in the 19th century. Their coat is spotted in summer, resembling the Fallow Deer, but they are smaller, and males possess rounded, branched antlers. Sika deer are often found in coniferous forest plantations and on heaths with acidic soils, especially in areas like the New Forest and parts of Cumbria. An identifying feature is the stag’s wide range of calls during the rut, which includes distinct whistles and wails.
The Smaller, Non-Native Deer
The remaining two established species are the smallest: the Muntjac and the Chinese Water Deer. The Reeves’ Muntjac (Muntiacus reevesi), introduced from China and Taiwan in the early 20th century, is often called the “barking deer” due to its distinctive alarm call. This small, stocky deer stands only about 50 centimeters at the shoulder and has a hunched posture. Male muntjacs have short, unbranched antlers but are most distinctly identified by the elongated, tusk-like canine teeth that protrude from their upper jaw.
The Chinese Water Deer (Hydropotes inermis), also introduced from Asia, is unique as it is the only deer species in England where neither sex possesses antlers. Instead, both males and females grow prominent canine teeth, with the males’ tusks being significantly longer for use in territorial disputes. This species has a russet-brown coat and a notably rounded facial appearance with large ears. The water deer prefers wet, marshy habitats, such as the Cambridgeshire Fens and the Norfolk Broads, but its range is gradually expanding.
Understanding Deer Population Dynamics
The presence of six established deer species is largely due to historical human intervention and a lack of natural predators. Introductions occurred in two main waves: ancient imports like the Fallow Deer, and more recent 19th and 20th-century introductions of Sika, Muntjac, and Chinese Water Deer, often released from deer parks. Since wolves and lynx were hunted to extinction in Britain, the populations of all six species have risen dramatically in recent decades.
This population increase necessitates active management to maintain ecological balance. High deer numbers lead to excessive browsing, which severely impacts woodland regeneration and reduces the diversity of ground flora and bird life. Management strategies, including regulated culling, aim to replicate the regulatory effect that natural predation would provide. The legal status of these animals is managed under the Deer Act 1991, which establishes close seasons for native species, while non-native species like the Muntjac often require intensive control measures to mitigate their environmental impact.
