A EFETIVIDADE DE ÁREAS PROTEGIDAS NA CONTENÇÃO DA CONVERSÃO ANTRÓPICA DE HABITATS NATURAIS NA REGIÃO NUCLEAR DO BIOMA CERRADO

Abstract

Studies evaluating the effectiveness of Protected Areas under the focus of natural habitat conservation define effectiveness as a measure of its influence to avoid the advance of anthropogenic conversion of natural areas. The overall objective of the study is to evaluate the effectiveness of conservation units in the core region of the Brazil’s Cerrado Biome, taking into account the influence of the restriction degree and governmental sphere on the performance of protected areas. It is desirable that such analyzes control the statistic bias caused by the correlation error and / or autocorrelation, which can generate underestimate or overestimate results. With the use of GIS tools and the Mahalanobis Score Matching method, it was possible to control these sources of bias. The results showed a positive influence of Protected Areas, with variations due to the restriction degree, and also the governmental sphere to which the Protected Areas belong.
