Abstract

The vegetation structure is a good indicator of the conservation condition of an ecosystem, since it reflects alterations
caused by anthropic action. This study proposes to analyze the phytosociological aspects of the Caatinga domain
under anthropic disturbance and their correlations with hydrological variables. Twenty-five 400 m2
plots were sampled in the municipality of Floresta - PE, Brazil. Phytosociological parameters such as density, frequency and dominance were calculated. The seasonality of plant area index was analyzed for six species. The association between structural
characteristics and hydrological variables (throughfall, stemflow and interception loss) in the species was evaluated
by multivariate analysis. A total of 930 individuals, six families and 10 species were recorded. The abundance of
the species Cenostigma pyramidale in the area may be an indicator of the degree of change in the vegetation. The
structural characteristics of the species revealed little association with rainfall partitioning.

Keywords: phytosociology, plant area index, semi-arid
