Corridors for jaguar (Panthera onca) in Mexico: Conservation strategies

Several species of carnivores, as jaguar, live in low densities and require extent habitat areas for survive. One of their main threats is fragmentation and demographic isolation. Identifying the habitat corridors, we can help the conservation of these species. We identified the viable and potential corridors between jaguar management and conservation areas for Panthera onca in Mexico. We considerate an ensemble model of the potential distribution of P. onca in Mexico, from which were identified jaguar management and conservation areas (JCMA). According to these attributes, we identified the possible habitat corridors between the JCMA with Corridor Designer. Thirteen habitat corridors were between all JCMA. However only seven were viable corridors and six were potential corridors. Also, in two areas of potential corridors were identified Stepping Stones that can help the jaguar movement between large fragments. In the thirteen habitat corridors, the main threats for jaguars are habitat fragmentation, roads, highway and possible conflict human-wildlife (livestock predation). The results from this work can provide the bases to take actions on the protection of connecting zones and alleviate the mortality of wildlife in these areas. (C) 2013 Elsevier GmbH.
