Uso da análise de paisagem no cadastramento de áreas de soltura de animais silvestres do IBAMA

Abstract

The withdrawal of millions of animals and plants from their natural environments through biopiracy represents one of the main causes of the reduction of biodiversity on the planet. This anthropic activity compromises different ecological processes such as pollination, seed dispersal, among others. Although there is specific environmental legislation for biopiracy, the results of legal efforts to ensure environmental preservation and conservation are still far short of what is needed to maintain biodiversity. Seizures of wild animals are still common in all states of our country, a fact that demonstrates how still the habit of having wild animals in captivity is rooted in the Brazilian population. The steps to control the trafficking of animals are: inspection, seizure, treatment and screening in CETAS, release or destination for legal captivity. For the release of wild animals, it is important to have sites that are conducive to their safety and establishment, and for this the choice of Areas of Relief (ASAS) and their targeting to what types of animals it can behave is a fundamental step which can guarantee the success of the release of overexploited animals and even the reintroductions of species threatened with extinction. Therefore, the present study intends to propose a reformulation of the procedures of registration of area of ​​release with the inclusion of a more detailed spatial analysis, originating from Landscape Ecology. For this, we performed a spatial analysis using descriptive metrics of the spatial structure of the landscape of a wild animal release area (ASAS) located in the municipality of Catu / BA and later evaluated which species would be most suitable for release in this region. Thus, through landscape ecology, the use and study of the metrics for the analysis of the landscape of release areas, when related to biological characteristics of the species to be released, could guide if the area in question has or not requirements for the survival of the specimens.
