Of Men and Wolves - The challenge of reintroducing the Mexican wolf and its journey home

Reintroducing a predator species to its historical habitat manifests dispute between wildlife agencies, environmental organizations, and people who are affected by the animals' presence on the landscape. The effort to reestablish the Mexican wolf in Arizona and New Mexico has met many challenges because the wolf competes with human use of the land. Wolves roam among domestic animals, threatening the livelihood of ranchers and perhaps altering the future of public land and the wilderness. Despite differences, and in some cases, opposition to the reintroduction of the Mexican wolf, the challenges have been met with sometimes ingenious, and sometimes practical and straightforward solutions. "The reintroduction of the Mexican wolves was the most difficult of any projects to reintroduce wolves anywhere," L. David Mech said. Mech is a senior research scientist at the Northern Prairie Research Center with the U.S. Geological Survey. He has studied wolves for almost 60 years. "The animals were all captive-bred and lacked the skills to survive in the wild," Mech said. Even though the wolves were catching elk, initially they also attacked livestock and roamed near human activity. "They were released in an environment that lacks large, expansive wilderness areas free of livestock." Conflict was inevitable...Recently, the U.S. Fish and Wildlife Service revised the section (10)j regulations to the Endangered Species Act regarding the Mexican wolf. Among other changes, the new guidelines include increasing the recovery area so the wolf can expand farther north into Arizona and New Mexico and south into its historical range in Mexico. Increasing the Mexican wolf's territory has advantages, but expanding its range into desert and other unsuitable habitat not part of its historical habitat could harm recovery and management efforts. The more wolves that get into trouble in those less suitable areas translate into more management. "We already lack the funding to launch a larger-scale wolf recovery program," deVos, from Arizona Game and Fish Department, said. Only a tiny portion of historical habitat remains in the U.S. Southwest, he said. The southwestern U.S. comprised about 10 percent of the Mexican wolf's original range, with the remaining 90 percent in Mexico. "They aren't called Mexican wolves for any other reason than they came from Mexico," deVos said...more
