Abstract
The available information on snake taxocenosis in Northeast Brazil is still incipient. To contribute to filling this gap, this study describes the composition of snake species from an Atlantic Forest Protected Area, Dois Irmaos State Park - PEDI, in Pernambuco. Data were collected using the methods:(1) occasional encounters, (2) active search, (3) interception and pitfalls, performed bimonthly for three years. 117 snakes were registered, distributed in five families, 21 genera, 23 species. Xenodon rabdocephalus species had its geographical distribution expanded by 742.2 km from the nearest registered location. The first order Jackknife index estimated a richness of 30 speciesand the rarefaction curve did not reach asymptote, indicating that there are still species to be found in the study area. The registration of rare and endemic species indicates the good qualityof the area, but have highlighted a warning about the warns of the anthropic pressure suffered by PEDI, putting at risk the conservation of its fauna and flora.
