The first organized captive breeding and reintroduction efforts for the Puerto Rican Crested Toad (PRCT) began in 1984 under the Association of Zoos and Aquarium’s Species Survival Program© and has been the longest continuous reintroduction program for an amphibian species in the world. In 2021, this successful conservation program metamorphosed into the Puerto Rican Crested Toad Conservancy (PRCTC), a 501(c)(3) non-profit, which is a broad consortium of zoos, individuals, and organizations working together for the long-term survival of the Puerto Rican Crested Toad. This program operates holistically to bridge the gap between in situ and ex situ efforts, providing resources, expertise, and genetically managed captive-bred offspring for recovery of the species.



To establish self-sustainable populations of Puerto Rican Crested Toads for their recovery and implement conservation actions that will mutually benefit humans and other native species.


  1. Expand breeding program capacity to bolster number of genetically diverse offspring for education, research, and reintroduction.
  2. Build effective partnerships and promote educational programs within Puerto Rico for the stewardship of PRCT and other endemics.
  3. Provide partners with technical assistance and expertise for priority in situ and ex situ research.
  4. Monitor health and disease risk of in situ and ex situ PRCT populations.
  5. Participate in development of threat mitigation strategies for sustainability of wild PRCT populations.
