The two phenomena involved [“diversity of individual stands, and relative differentiation of vegetation patterns along topographic moisture gradients”] suggest the need for distinguishing three aspects or levels of species-diversity in natural comnmunities: (1) The richness in species of a particular stand or community, or a given stratum or group of organisms in a stand. Fisherʼs (1943) alpha index is one means of measuring this, which may be designated primary or “alpha” diversity.
