Release captive-bred Mallorcan midwife toads Amphibian Conservation

A replicated study in 1989–2001 in Mallorca (Griffiths, García & Oliver 2008) found that released captive-bred Mallorcan midwife toads Alytes muletensis established stable and in some cases increasing, breeding populations at all 18 release sites. Seventy-six captive-bred tadpoles were released at two sites in 1989. Toadlets and tadpoles were then released on an annual basis up to 1997 and less regularly until 2001. Toads were screened for disease before release. Tadpoles were counted annually at the 18 release sites.
