Rehabilitate injured, sick or weak mammals
A study in 2008-2013 in two forested, mountainous areas of north-west Spain (Penteriani et al. 2017) found that after treating three young female brown bears Ursus arctos for injuries and releasing them back in to the wild, one was recaptured 21 days after release and two survived for at least 4-7 years. One cub was recaptured 21 days following release after repeatedly entering villages during the day. The other cub was monitored for 239 days, then seen seven years after release. One female sub-adult was monitored for 292 days, then seen four years after release with a dependent cub. The two bears remaining in the wild both established home ranges (90% of cub’s home range: 182 ha; 90% of sub-adult’s home range: 2,816 ha). In 2008-2013, three young bears were taken into captivity for 41-145 days to be treated for injuries and were then released to one of two sites, 3-14 km from where they were captured. One was monitored daily by radio-tracking for 239 days and two were monitored hourly by GPS for 21 and 292 days until they were recaptured, or the collar was lost.
