1. It is often stated that wild deer in Great Britain are increasing in range and number. This study presents the first quantified estimate of national range expansion for all six species. From national surveys of deer presence in 10 km squares between 1972 and 2002, the red deer range is estimated to have expanded at a compound rate of 0.3% per year, fallow deer at 1.8%, Chinese water deer at 2.0%, roe deer at 2.3%, Japanese sika at 5.3% and Reeves’ muntjac at 8.2%. 2. Each species is expected to expand its range further for the foreseeable future. The most widespread species, roe deer, is predicted to be present within 79% of all 10 km squares in mainland Britain within 10 years. 3. Deer range expansion brings a combination of benefits and costs, and some degree of management is considered necessary to limit both environmental damage and deer suffering.
