Release captive-bred toads
A replicated study in 1982–1986 in Attwater Prairie Chicken National Wildlife Refuge in Texas, USA (Quinn et al. 1989, Dodd & Seigel 1991) found that released captive-bred and head-started Houston toads Bufo houstonensis did not establish populations. Eight released males but no females were recorded during five years of monitoring. Two egg strings were found in 1985. Survival was low as many tadpoles were predated. Over five years, 62 adult, 6,985 metamorphs and 401,384 eggs were released at 1–10 sites/year. Animals were either captive-bred or eggs were collected in the wild and raised in captivity (indoors and outdoors) before release. Monitoring was undertaken nightly in February–June 1982–1986.
