We compared species richness estimates for eight camps sampled in 1997 to inventory the herpetofauna of the Iwokrama Forest. Regression analyses and Coleman curves documented that species richness was lowest in the camp at the highest elevation. We also found that the four standard sampling methods we used in 1997 differed significantly in detecting species. All methods were necessary to generate a complete species list of 141 species, but visual encounter surveys and opportunistic collecting discovered the largest number of species in Iwokrama. Our results show that meaningful comparisons of species diversity are only possible when effort has been standardized.
