Resumo
The efforts to minimize the growing loss of habitats and threatens to biodiversity are
increasingly based on objective criteria, which allow prioritize areas and species in need of
preservation, taking into account the limitations in both natural and economic resources.
These criteria are fundamental for the reserve selection and design, mainly at regions severely
affected by land use intensification. In particular, the use of mathematical modeling, enabling
the identification of more efficient alternatives, is an important subsidy to conservation
challenge. Specifically, in this dissertation we present a new approach for the selection of
priority areas for conservation, which considers both the quality and ecological feasibility of
the remnant vegetation in the Cerrado areas of the State of Goiás, as well as the practical and
legal aspects regarding the use of watersheds for territorial management. This proposal, based
on a non-linear mathematical model, allows the parameters to vary according to the socialeconomical
and environmental interests, thus generating distinct solutions and scenarios.
Among the possible outcomes, we highlight as an "optimum" solution, the one with a large
number remnant vegetation areas within riparian environments, which serves the purpose of
strengthening spatial connectivity and natural corridors. In fact, this model can be used either
to promote the conservation of large remnant vegetation patches, as well as to optimize the
restoration of degraded areas, mainly in riparian environments, through the generation of
alternative spatial patterns aiming at a more efficient connectivity in highly converted areas
