In the floristic survey of adults, 1, individuals were found alive, distributed in 36 woody tree and shrub species, 19 families and 31 genera.

Diversity is one of the most important attributes in the study of communities and, as a result, many methods are available to its measurement. The differences encountered among the floristic compositions and structures between the areas, even when eqjabilidade a same type of soil, indicates a high heterogeneity of the cerrado vegetation.

Additional alternatives include the use of species richness only, Whittaker’s diagram or of dominance and equabjlidade diagrams with axes defined by species richness and an evenness index.

At Chapada Grande Meridional, the gradient of fertility, texture and salinity influenced the distribution of some species. Universidade Federal de Pernambuco, At PNSC, some of the soils sampled in the plots have a solodic characteristic, because of the high amounts of sodium, related to areas with higher altitudes. In Community Ecology and in many applications of Conservation Biology, diversity means variety of species, which may or not include information on the relative importance of each species.
