Margalef's pigment diversity index was used to estimate the successional stage of a plankton community in a mountain lake. Although, other data suggested an oligotrophic lake with an immature plankton community, the index indicated a much older an dstable ecosystem. It seems apparent that more comparative studies on natural ecosystems are needed before the index can be valualbe in estimating successional stages in aquatic communities.
