A formula to calculate the area of samples that would provide the necessary level of completeness of species richness survey of a cenosis has been deduced. The model is based on a stochastic differential equation, describing random fluctuations in species abundance, and also on the assumption about the Poisson distribution of individuals in space. The calculations are illustrated by the example of the littoral polychaete taxocene in Vityaz Bay of Possiet Bay, Sea of Japan.

Key words: "species-area" curve, gamma-distribution, parameter estimation.
