Descrição

Justification:

The current population of Maned Wolves is estimated at approximately 17,000 mature individuals (≥ 2 years of age), with the majority of the population (>90%) in Brazil. In the last decade or so, the species’ main habitats in Brazil have been subject to intense deforestation. A population viability model for Brazil generated using real and predicted deforestation rates over 15 years (three generations) resulted in an estimated reduction of ~20% in the metapopulation (based on current estimates of habitat loss ranging from 1.0 to 1.5% per year). If deforestation reaches the maximum estimated rate of loss (2% per year), then simulation suggests a national population reduction of 56% at the end of 100 years (Paula et al. 2008, Paula and Desbiez 2014). In addition to the estimated population reduction from deforestation, the species is also subject to other threats, including road kills, direct persecution by humans, and disease due to contact with domestic animals (Paula and Desbiez 2014). In other range countries (Argentina, Paraguay and Bolivia), the species’ status is even more precarious with small isolated populations and declining numbers due to the low quality of habitat and hunting. The Maned Wolf does not meet the thresholds for listing under criteria B, C or D, but taking into account the combined impacts of habitat loss, persecution and disease, it approximates the thresholds for listing under A3, and is therefore assessed as Near Threatened. The species’ situation is considered to be of major concern due to the various threats acting throughout its entire range and should be regularly re-evaluated.
