摘要: A phytosociological survey was conducted at one area belonging to the Serido Ecological Station test hypothesis that vegetation region is open and low. All woody plants with stem perimeter breast height > 3 cm were counted, within 100 plots, 10×10 m, each had its height, perimeter, crown projection diameters measured, aboveground biomass estimated. Fifteen species found, 15 genera 10 families, a Shannon diversity index of 1,94 . These values are below those most caatinga places elsewhere. Mimosoideae family (three). structural variables, except density, (3,250 plant ha-1, basal 6.1 m2 maximum 9.5 m, diameter 37 cm, total 8,723 25 mg ha-1) lower than Aspidosperma pyrifolium Mart. dominant comprising about half areas biomass. The small size openness confirmed, indicating has physiognomic type distinct from other ones.
