Yellowstone to Yukon Conservation Initiative or Y2Y is a transboundary Canada–United States not-for-profit organization that aims to connect and protect the 2,000 mile (3,200 kilometre) Yellowstone-to-Yukon region. Its mission proposes to maintain and restore habitat integrity and connectivity along the spine of North America's Rocky Mountains stretching from the Greater Yellowstone ecosystem to Canada's Yukon Territory. It is the only organization dedicated to securing the long-term ecological health of the region. Since 1993, more than 450 partner groups have joined forces to support the shared mission and vision. Y2Y's work is a collaborative effort of conservation groups, government agencies, Indigenous governments, landowners, wildlife scientists, planners, businesses, economists, and other individuals and groups interested in protecting native wildlife, ecological processes, and wilderness in the Rocky Mountains of North America. Existing national, state, and provincial parks and wilderness areas anchor the system, while the creation of new protected and special management areas provide the additional cores and corridors needed to complete it. This network is built upon the principles of conservation biology, various focal species assessments, the knowledge of local and traditional residents, and the requirements for sustainable economies. Mission Connecting and protecting habitat from Yellowstone to Yukon so people and nature can thrive. Primary role To achieve its vision across 2,000 mi (3,200 km), Y2Y protects core wildlife habitats, keeps those habitats connected and inspires others to engage in similar work. Y2Y highlights and focuses on local issues that have implications for the region as a whole. The organization engages in landscape-scale conservation, an approach that focuses on actions and management across large areas, such as entire watersheds. The organization's role is to set the context for regional conservation work by providing the vision for a healthy Yellowstone to Yukon landscape, and to bring partners together to achieve as a network what cannot be done by any one group alone. The initiative proposes a system of wildlife corridors linking core protected reserves with buffer zones acting to further protect the system from industrial and urban development. History Between 1991 and 1993, Pluie, a wolf radio-collared in southern Alberta, was tracked as it traveled more than 100,000 square kilometers and covered an area 10 times the size of Yellowstone National Park and 15 times that of Banff National Park. Pluie crossed more than 30 different political jurisdictions (including three states, two provinces, private lands, and First Nation’s territories) before being shot and
