The land snail diversity in a square kilometre of tropical rainforest in Okomu Natioal Park, Edo State, Nigeria

The land mollusc fauna in a single square kilometer of undisturbed tropical rainforest in Okomu National Park, Edo State, Nigeria was surveyed by sampling thirty 20-m2 plots. Sampling methods were similar to those used in the rainforests in Cameroon and Sabah. Samples were collected by sieving leaf litter, topsoil and by hand picking within the forest floor or vegetation. A total of 1442 individual molluscs belonging to 46 species in 11 molluscan families were collected.
