| The Paraguayan Chaco as one of the last refuges for threatened mammals of Cono Sur | |
| 2015 Paraquaria Natural (3): 37-47 | |
The Gran Chaco is an ecoregion covering 1.5 million km2 of Argentina, Bolivia and Paraguay and is considered one of the last "wilderness" areas in the Neotropics. Currently, the Paraguayan Gran Chaco is undergoing significant changes in land use consisting of deforestation for the creation of livestock pasture. This widespread deforestation and habitat fragmentation is converting the Paraguayan Gran Chaco from an important conservation area for large mammals to one under risk of losing important populations of large mammals from habitat loss and fragmentation. We analyzed the conservation potential of the Gran Chaco for large mammal species, including 12 species listed as vulnerable or higher, among which the jaguar (_Panthera onca_) stands out, within the context of land use trajectories and the presence of national and trans-boundary protected areas. We emphasize the need for the national and international conservation community to recognize the importance of the Paraguayan Gran Chaco for the long-term conservation of large mammals in austral South America. |
