Conservation status evaluation and execution of conservation actions for maned wolf in the state of São Paulo: Wolves of Pardo Project

The maned wolf (Chrysocyon brachyurus), the largest canine in South America, is listed as vulnerable (VU) in the state of São Paulo and in the rest of federative units they are found. Like all other large sized carnivores, the maned wolves are susceptible to a great diversity of threats. Knowing these threats and bringing the community closer to conservation actions for endangered species are the most viable strategies to obtain success in the reduction of threats and promote preservation of the wild population in the long term.

One of the key issues of conservation is to understand how landscape changes, due to development processes of urban and agricultural expansion, affect biological diversity. While some species are more sensitive to human impacts over their natural habitat, others favor with the anthropic process (Quigley e Crawshaw 1992, Silva 1999, Crooks 2002, Mazzolli et al. 2002, Ranvaud and Bucher 2006, Ferraz et al. 2007, Palmeira et al. 2008). To comprehend the relationship between environmental conditions and potential distribution of species, is essential in the elaboration of adequate strategies for biodiversity and ecosystems conservation.

This project specifically constitutes the Conservation Program of the Maned Wolf, within the structure of National Research Center of Carnivore Mammal Conservation (CENAP), a specialized center of Chico Mendes Institute for Biodiversity Conservation (ICMBio). The program is part of a long-term multidisciplinary evaluation that exists since 2004. Although the amount of information gathered on the specie has increased over the past few years, which allows new conservation strategies to be traced, it will be the first time an area, besides southwest of Minas Gerais, is systematically sampled using the same methodology within this program.

The objectives proposed in this project fulfil part of the gaps presented by the National Action Plan (PAN) for Wild Canine Conservation, which substitutes the Maned Wolf PAN (discontinued in 2016). Therefore, the implementation of the document is indispensable for the conservation of this species. The project aligns with the official conservation strategies of this species.
The project takes place in the northeast sector of the state of São Paulo, considering the Rio Grande hydrographic bay in general. Specifically, it is in the sub-basins of Baixo Pardo, Sapucaí, Pardo and Mogi-Guaçu (in Pardo River Bay). It is bounded by the HEPP Limoeiro, HEPP Euclides da Cunha and HEPP Caconde (São José do Rio Pardo, Mococa, Caconde in the state of São Paulo and Botelhos and Poços de Caldas in the state of Minas Gerais) and SPH Mogi-Guaçu (Mogi-Guaçu, Mogi-Mirim and Itapira in the state of São Paulo). All under concession of AES Tietê, a company of the energy sector.

The project´s overall goal is to evaluate the threats on maned wolf survival in the northeast of São Paulo, to direct strategies for conservation and management of the species in areas of direct and indirect influence of HEPP under AES Tietê control.
This project executed by the Pro-Carnivoros Institute has partnership with AES Tietê and the collaboration of ICMBio-CENAP.
