摘要：

The composition and activity of the snake community of the Pa-hay-okee wetlands of Everglades National Park is described. The study was conducted in February and March 1986 and from February 1987 to January 1989. A total of 1172 individuals of 16 taxa were observed, with Thamnophis sauritus, T. sirtalis, Nerodia fasciata pictiventris and Agkistrodon piscivorus representing 89.2% of the total sample. The seasonal activity of the snakes was closely related to fluctuations in the water table. Periods of greatest snake activity coincided with the periods of greatest human visitation. Seventy-three percent of all snakes observed on the park's main road were either injured or dead. Management recommendations are provided to minimize loss.
