Rehabilitate injured, sick or weak mammals Terrestrial Mammal Conservation

A study in 2007–2014 in a grassland reserve in Corrientes Province, Argentina (Di Blanco et al. 2015; same experimental set-up as Di Blanco et al. 2017) found that over half of released rehabilitated and captive-reared giant anteaters Myrmecophaga tridactyla, some of which were kept in holding pens and provided with supplementary food, survived for at least six months. At least 18 of 31 released giant anteaters survived for a minimum of six months. Long-term survival and the fate of the other 13 anteaters is not reported. In 2007–2013, thirty-one giant anteaters (18 males, 13 females; 1–8 years old) were released into a 124-km2 private reserve. Hunting within the reserve was prohibited and livestock were absent. Three anteaters were wild-born but rehabilitated in captivity from injuries, 22 were wild-born but captive-reared and six were from zoos (origin not stated). Of the 18 surviving anteaters, six had been released after a short period in a 0.5-ha pen at the release site and 12 after 7–30 days in a 7-ha pen. Supplementary food was provided for several weeks after release. In 2007–2014, thirteen anteaters were tracked for less than six months, and 18 were tracked for 6–46 months.

Provide supplementary food during/after release of translocated mammals Terrestrial Mammal Conservation

A study in 2007–2014 in a grassland reserve in Corrientes Province, Argentina (Di Blanco et al. 2015; same study site as Di Blanco et al. 2017) found that over half of released rehabilitated or captive reared giant anteaters Myrmecophaga tridactyla, some of which were provided supplementary food and initially kept in holding pens, survived for at least six months. At least 18 of 31 (58%) released giant anteaters survived for a minimum of six months. Long term survival and the fate of the other 13 anteaters is not reported. In 2007–2013, thirty-one giant anteaters (18 males, 13 females; 1–8 years old) were released into a 124-km2 private reserve. Hunting within the reserve was prohibited and livestock were absent. Three anteaters were wild-born but rehabilitated in captivity from injuries, 22 were wild-born but captive-reared and six were from zoos (origin not stated).

Provide supplementary food during/after release of captive-bred mammals Terrestrial Mammal Conservation

A study in 2007–2014 in a grassland reserve in Corrientes Province, Argentina (Di Blanco et al. 2015; same experimental set-up as Di Blanco et al. 2017) found that over half of released captive reared or rehabilitated giant anteaters Myrmecophaga tridactyla, some of which were provided supplementary food and initially kept in holding pens, survived for at least six months. At least 18 of 31 (58%) released giant anteaters survived for a minimum of six months. Long term survival and the fate of the other 13 anteaters is not reported. In 2007–2013, thirty-one giant anteaters (18 males, 13 females; 1–8 years old) were released into a 124-km2 private reserve. Hunting within the reserve was prohibited and livestock were absent. Twenty-two anteaters were wild-born but captive-reared, six were from zoos (origin not stated) and three were wild-born but rehabilitated in captivity from injuries. Of the 18 surviving anteaters, six had been released after a short period in a 0.5-ha pen at the release site and 12 after 7–30 days in a 7-ha pen. Supplementary food was provided for several weeks after release. In 2007–2014, thirteen anteaters were tracked for less than six months, and 18 were tracked for 6–46 months.
