Life History, Abundance, Activity, and Special Behaviors
Trends and Threats
The SSP protected a breeding site in both northern and southern Puerto Rico. The northern breeding site was not protected and no toads have been seen there since 1988. The southern site has been protected, however only about 1,000 adult toads have been observed there. Over the time that the SSP has been working with this amphibian, the population of B. lemur at the southern site has decreased to around 200 adults (Johnson 1999).
Another contributor to the decline of B. lemur has been the introduction of the Giant Marine Toad (Bufo marinus), which competes for breeding sites, food, and general habitat. The purpose of the introduction (which took place in the 1920s) was to control sugar cane grubs Rats and the Indian mongoose are also believed to compete with B. lemur (Johnson 1999).
