Description

The wildcat is Britain's only remaining native cat species. It is similar to a domestic tabby but larger, stockier and with a black-banded bushy tail. It is restricted to Scotland, where it inhabits the forested margins of moorland. It is under severe threat from hybridisation with feral cats and disease. The animal was routinely culled to reduce predation on game, but it was protected in 1988 under the Wildlife & Countryside Act. The wildcat has been recorded by the NGC only between 1971 and 1987.

Distribution and abundance

In the UK, the wildcat is restricted to central and northern Scotland, and is absent from the Scottish islands. Reports of wildcats further south probably refer to feral cats, although unofficial releases cannot be ruled out.

Estimates of wildcat abundance (numbers of individuals in the spring) across the UK, from Harris et al. (1995):

United Kingdom 3,500
England 0
Scotland 3,500
Wales 0
N Ireland 0

Recent trends from the National Gamebag Census

United Kingdom

Index of bag density from 1971 to 1987 (see statistical methods and interpretational considerations).
Error bars represent 95% confidence intervals.

Wildcat trend United Kingdom

Data were available only for the period 1971-1987, during which there was no significant trend in the bag index. A total of 274 wildcats were recorded by the NGC from 40 shooting estates in central, eastern and north-eastern Scotland in 1984-1985 (Easterbee et al. 1991).

Comparison with BBS mammal data

No comparison with the NGC trend is possible because too few wildcat records are received through the Breeding Bird Survey (BBS) organised by the British Trust for Ornithology.

Long-term trend from the National Gamebag Census

There are too few bag records of wildcat to produce a trend starting before 1971.
