  1. Translocate to re-establish or boost populations in native range

    A study in 1972–2011 in a grassland and rock area above the treeline in central Appenines, Italy (Lovari et al. 2014) found that a population of translocated red deer Cervus elaphus released in groups persisted at least 24 years after release, but over the same period, the density of Apennine chamois Rupicapra pyrenaica ornata in the area almost halved. Red deer pellets were detected in 31-35 out of 38 (82-92%) sampling plots 23-24 years after translocation. However, authors reported that over a similar period, chamois density almost halved in the core area of their range (1984–1985: c. 38/100 ha; 2012: c. 20 individuals/100 ha). Authors found a large space (> 75%) and diet (> 90%) overlap between deer and chamois, an increase in unpalatable plant species and a reduced bite rate of adult female chamois in patches also used by deer (see paper for details). Forty-five red deer were translocated into Abruzzo, Lazio and Molise National Park in 1972 (0.5 individuals/100 ha). A further 36 deer were released in groups of 7-10 individuals (in 4 operations) in 1972-1987. In June–October 2010 and 2011, the presence/absence of groups of >5 red deer pellets was recorded in circular, 5-m radius, sampling plots, randomly placed in 38 grassland sites. Sites were located in a 65-ha mountainous area above the treeline.
