To study the use of plant resources by a rural community in a seasonal dry forest, plots were established in a disturbed area and in a relatively preserved area. The study was carried out in caatinga vegetation located at the municipality of Alagoinha (08º27'59" S and 36º46'33" W), state of Pernambuco, Northeastern Brazil. The results show a pattern of medicinal resources offering similar to that found in other tropical forests, in which the disturbed areas or those of secondary vegetation are a major source of medicinal plants. Nevertheless, a new pattern was evidenced as it was found that disturbed areas are not preferred by local people, and that it may be related to temporal availability of resources (adaptation to the characteristic seasonality of the vegetation type) and to the permanence of cultural values and basic knowledge on plants of the natural vegetation, which are of major importance for the community.
