Abstract: The fragmentation of carnivore habitat in the Rocky Mountains on both sides of the U.S.-Canada border is an ongoing threat to the survival and recovery of these populations. Human developments are the cause of this fragmentation. Major developments causing fragmentation include private land conversion into homesites and highway construction and improvement. If carnivores such as grizzly bears (Ursus arctos horribilis), wolves, (Canis lupus), wolverines (Gulo gulo), lynx (Lynx lynx), and fishers (Martes pennanti) are to survive and recover to healthy population levels in the Rocky Mountains, the issue of fragmentation must be addressed in a proactive and effective manner.

Identifying and Managing Wildlife Linkage Approach Areas on Public Lands
A Report to the Interagency Grizzly Bear Committee
Prepared by the IGBC Public Lands Wildlife Linkage Taskforce June 17, 2004
INTRODUCTION Background The Grizzly Bear Recovery Plan (U.S. Fish and Wildlife Service 1993) outlines numerous tasks required to achieve recovery of the grizzly bear (Ursus arctos), a species listed as threatened in the conterminous United States under the federal Endangered Species Act of 1973 as amended (PL 93-205). Task #37 of the Plan calls for evaluation of linkage potential between grizzly bear recovery zones. U.S. Fish and Wildlife Service completed the report Identification and Management of Linkage Zones for Grizzly Bears Between the Large Blocks of Public Land in the Northern Rocky Mountains (Servheen et al. 2001, hereafter referred to as “Linkage Report”) in fulfillment of that task.
