Release translocated/captive-bred mammals to areas outside historical range Terrestrial Mammal Conservation

A study in 1980–2007 in a mountain grassland site in the Mézenc Massif, France (Ramousse et al. 2009) found that after the release of translocated Alpine marmots Marmota marmota into a site outside their historical range, numbers increased more than four-fold over 27 years. Twenty-seven years after the onset of the translocation, marmot numbers had increased to 492, from the 108 originally released. Population growth fluctuated over time with some population declines in 1990, 1993, 1997 and 2001 (see original paper for details). In 1980, eleven marmots were translocated into a mountain area outside their historical range. This was followed by seven reinforcements (translocation dates not provided), with a total of 108 translocated individuals by 2001. Marmots were monitored discontinuously until 1988, and then annually (five times through spring to autumn). Monitoring details are not provided.
