Análise da paisagem e suas relações com ambientes florestais de áreas úmidas protegidas.

Abstract

The land use and occupation has modified the landscape structure, mainly wetlands. The creation of protected areas has contributed to the territorial planning, landscape structure and the development of conservation strategies. In order to understand the relationship between the landscape use and management and the arboreous vegetation of the protected wetlands, was performed the evaluation of land use and occupation and the sizing of fragments in the region of a full protection conservation units (CU) (PEVRI), also the structure and composition analysis of the remaining arboreous vegetation patches. The result was that CU fragments are more conserved than those in the buffer zone (BZ), showed in this study by the larger basal area and volume of the arboreous species and less incidence of exotic invasive species. The land use differed between these areas, the CU had more natural areas than BZ. Unlike of species composition, the values of diversity and richness not differed between the fragments of CU and BZ. Thus, the landscape management by increasing and protection natural areas, including in BZ, can favor the recovery of arboreous vegetation in protected wetlands, combating biological invasion and effectively maintaining regional biodiversity.
