ZELLER, PANTHERA FOUNDATION; WILDLIFE CONSERVATION SOCIETY WCS WEB OF CONNECTIONS The likely routes jaguars use to move between population groups form a web of 196 corridors stretching through 18 countries. The corridors, mapped using observations of local experts and habitat data, are now being verified and refined by field research and satellite imagery. CORRIDORS OF CONCERN Jaguars prefer to travel in dense forest or, in a pinch, through farmland with suitable cover. Only thin ribbons of such habitat still exist between some jaguar population groups, threatening to isolate the cats geographically---and genetically.
