  1. Head-start amphibians for release

    A replicated study in 2007–2012 of Houston toads Anaxyrus houstonensis in Texas, USA (Forstner & Crump 2011, Crump 2012) found that eggs were successfully reared to toads in captivity. In 2007, 35% of juveniles survived in captivity and by 2010 survival had increased to 50–55%. By 2012, approximately 700 toads were held in three captive breeding facilities. In 2007, 500 toads were released, in 2009 it was 4,194 and in 2010, 14,728 were released back into the wild at 10 sites. Thirty-one egg strands were collected from the wild and tadpoles raised in biosecure rooms and four outdoor exclosure tubs.
