Bases para a exploração sustentável de Himatanthus articulatus (Vahl) Woodson, Apocynaceae, nas savanas do Amapá-Brasil.

Abstract

This study sought to associate data on vegetation structure and distribution modeling to indicate areas with greater aptitude for the practice of sustainable extraction, already very important in the economy of the state of Amapá and targeted H. articulatus, an important species of medicinal use in Amapá. From inventory and herbarium data, referring to specimens collected in Amapá, the locations of occurrence of the species in the savannas of Amapá were identified. The spatial distribution modeling (SDS) indicated the locations with the highest potential occurrence, and consequently the highest exploration potential, that exhibited values of model evaluation between 0.75 and 1.00, and should be taken into account values of PAD and height. Even so, for a more assertive recommendation, studies should be carried out, such as the relationship between the demand for the raw material used in the production of the medicines and the capacity for recovering the specimens submitted to the exploration of the medicinal part, as well as their potential for cultivation.
