| Descripción: | Within Braulio Carrillo National Park (BCNP) of Costa Rica, there is a lack of quantitative data regarding the snake community despite its informally reported abundance and relevance to human health. The objective of this research was to document the diversity of snakes within the Quebrada González sector of BCNP. We searched for snakes using visual encounter surveys along several trails, as well as in quadrants and transects within the forest interior. We captured 272 individual snakes across 28 species and five families. Bothrops asper (Fer-de-Lance) and Bothriechis schlegelii (Eyelash Viper), both Viperids, were the most abundant species encountered, most likely due to their generalist habits. Most other snake species were found in smaller numbers but with roughly equal frequency to each other. Snake species richness and relative abundance were similar between the sampled trails but did show temporal variation during the study period with higher values during the rainy season from April to August. Species composition between the sampled trails was similar, but we did detect some differences likely due to differing habitat characteristics. The species diversity identified here may have been positively affected by the location of the site along an elevational and habitat gradient with high temperatures and precipitation, but likely remains incomplete due to the preliminary nature of the survey and the difficulty of detecting many snake species. A species accumulation curve suggests that the inventory was approximately 81% complete; additional, less abundant species would likely be identified with increased sampling effort and additional survey techniques |
