Chinese Water Deer (Hydropotes inermis)

Chinese Water Deer Thermal Drone Surveys

As the name implies, the Chinese Water Deer (Hydropotes inermis) is not native to the UK, having been introduced from China in the 19th century. Though originally confined to parks and zoos, some individuals escaped and established free-ranging populations, primarily in parts of eastern and central England.

Chinese Water Deer are small in stature, standing only around 0.5–0.6 metres at the shoulder. Their coat is typically rich brown for most of the year, becoming duller and greyer in winter.

A defining characteristic of this species is the absence of antlers. Instead, both males (bucks) and females (does) possess prominent tusks and elongated upper canine teeth. The bucks' tusks are longer and more pronounced, used in displays and in combat with rivals, performing a similar role to antlers in other deer species. The does tusks are shorter and less visible.

Though non-native, Chinese Water Deer are generally not considered as invasive as Muntjac due to their limited range and impact but our evidence shows they are spreading rapidly.

BHWC offers specialist surveys for Chinese Water Deer, using thermal drones and field-based techniques to detect and monitor populations - particularly useful given their small size, solitary behaviour, and habitat preferences.
