Abstract [en]

Human-induced land use change (LUC) is the most important driver of biodiversity loss. In Brazil, this process is particularly concerning considering that here are the most extensive tracts of tropical forest and other rare habitat types which host unique biodiversity. The preservation of much of this area is highly dependent on the implementation of the Forest Act, the central legal framework regulating the conservation of native vegetation on private land in Brazil. Recent studies provide a modelling framework for assessing the impacts of the Forest Act on the protection of native vegetation and associated carbon stocks for the entire Brazilian territory. However, there is not sufficient knowledge on the efficiency of this legislation in protecting areas of high and unique biodiversity in Brazil.

This study aims to apply the existing land use governance assessment (LUGA) model to quantify the extent to which the Forest Act protects biodiversity. For this purpose, we construct indicators at fine-scale levels to capture the multiple dimensions of biodiversity (species richness, genetic, and functional diversity) and how these are related to the native vegetation. Using state-of-the-art databases of species distribution data, GIS-based modeling frameworks are developed and adapted to identify values of native vegetation related to the preservation of biodiversity in general, and endangered species in particular, and ecological connectivity. The results are evaluated for Brazilian regions where the LUC pressure is recognized to be most significant. The final model output consists of geoexplicit indicators at a high resolution, which informs about the degree of biodiversity protection provided by the Forest Act. The information provided by this project can support decision-making related to the selection of areas of high importance for biodiversity protection at local and regional levels. Further, it can potentially contribute to efficient use of resources and improved effectiveness of incentive mechanisms in promoting conservation of unprotected native vegetation of high biodiversity value.
