  1. Use holding pens at release site prior to release of captive-bred mammals

    A study in 1998–2001 on a grassland site in Montana, USA (Smeeton & Weagle 2001) found that after the release of captive-bred swift foxes Vulpes velox using holding pens prior to release, most animals survived for at least one to three years, and some successfully bred. One to three years after introduction, a maximum of 69 of the 76 reintroduced foxes were still alive. Over the three years after introduction, 24–29 cubs were born in the wild. In the summers of 1998–2000, a total of 76 foxes were held in pens at the release site and, after 10 days, were released. Twenty-four animals were radio-tracked in 1999–2001. Methods used in the study to determine mortality and breeding success were unclear.
