Resumo


This study aimed to assess the functional connectivity of Mata dos Godoy State Park (PEMG) and its buffer zone (ZA), covering an area of 38,950.45 hectares, spanning parts of the municipalities of Londrina, Arapongas, and Apucarana. The objective was to identify forest patches with enhanced connective capacity among themselves, which are utilized by Tapirus terrestris. The land use and land cover shapefile provided by the Instituto Água e Terra (IAT) was employed for spatial delineation of the studied landscape mosaic. Landscape structure analyses were conducted using ArcGIS 10.3, and functional connectivity assessments were carried out using Conefor Sensinode 2.6. This spatial delineation resulted in the functional analysis of 266 remnants of native vegetation, encompassing a wide range of area sizes, accounting for 28.75% (11,209.74 hectares) of the studied landscape mosaic. Among these patches, 255 (95.86%) were categorized as having low connectivity, 10 (3.76%) as having moderate connectivity, and only one (0.38%) as having high connectivity. The dIIC index for the high-priority patch (=78.50%) indicates that, despite the current landscape conditions differing significantly from the original state, it remains suitable for Tapirus terrestris. The most crucial habitat patch for functional landscape connectivity, considering the species' dispersal capacity of 2,000 meters, is the one encompassing PEMG. In conclusion, despite having a predominantly anthropogenic matrix, the buffer zone (ZA) of PEMG exhibits connectivity indices demonstrating a substantial degree of connectivity, primarily maintained by a single habitat patch that includes PEMG.
