Passagens de Fauna: um experimento para o mico-leão-preto (Leontopithecus chrysopygus)

Abstract

The Black Lion Tamarin, Leontopithecus chrysopygus, is a primate species endemic to the State of São Paulo and considered State environmental patrimony. It is on the international red list of species in the category "Endangered", mainly due to loss and fragmentation of its habitat. Roads cause direct negative impacts to wildlife, such as road kill mortality and the barrier effect. Wildlife crossing structures are implanted as a form of mitigation for both trampling and barrier effect, and canopy bridges are specific structures for semi-arboreal and arboreal species, such as primates. The aim of this study was to implement two "canopy bridges" fauna passages with distinctive designs in the Vicinal Domiciano de Souza road, GRI 253, Guareí-SP, in the crossing and trampling of black tamarin individuals, and involve the local community in protecting biodiversity. The fauna passages were installed in February 2017 and monitored for 13 months continuously, allowing the verification of functionality, use preference analysis and identification of the period of adaptation to the new structures inserted in the habitat. During the period of execution of the work, scientific dissemination actions were carried out in which information about biodiversity and local problems was shared with the purpose of sensitizing and engaging the community, thus promoting the formation of biodiversity conservation agents.
