Northern coastal plain collections have been made near Isabela, Quebradillas, Arecibo, Barceloneta, Vega Baja, and Bayamon. To date, over 4,OOO toadlets have been produced in captivity at the Metro Toronto Zoo and returned to Puerto Rico. Historically, the Puerto Rican crested toad has been collected on the island of Virgin Gorda in the British Virgin Islands. The known historic distribution on Virgin Gorda is very limited and the species has not been observed there for at least 2 decades. It is assumed to have been extirpated from that island.
Exact numbers are unknown.
The Guanica Commonwealth Forest population is relatively stable and consists of approximately 1,5OO to 2,OOO individuals. The northern population consists of approximately 25 individuals. Nothing is known about population numbers in other localities, especially since the species is very difficult to encounter on a periodic basis. Adult toads are semifossorial and widely dispersed when not breeding. Because of this cryptic behavior, the location or even presence of adult toads when not breeding is difficult to detect.
