Translocate to re-establish or boost populations in native range Terrestrial Mammal Conservation

A replicated study in 1971–2014 in 13 forested mountainous areas in Catalonia, Spain (Torres et al. 2016) found that translocating roe deer Capreolus capreolus resulted in a six-fold increase in distribution after multiple translocation events. Forty-two years after the first translocation roe deer were present in 85% of Catalonia (2013: 288 10 × 10 km squares), a six-fold increase on the area occupied compared to 23 years after the first translocation (1994: 52 10 × 10 km squares). Between 1971 and 2008, five hundred and fourty-two translocated roe deer were released in 13 areas across Catalonia. Deer were captured from the wild in France and Spain and released after 24 hours directly into protected areas. In 1971–1992, animals (46 individuals) were translocated into areas already occupied by roe deer and in 1993–2008 into areas where roe deer were currently absent (496 individuals). Distribution data were obtained from terrestrial mammal distributions atlases supplemented by traffic police reports, hunting data and sightings by volunteers.
