Large-scale corridor examples
The Great Eastern Ranges Initiative is a landscape-scale conservation corridor that stretches along the eastern coast of Australia from Victoria to far north Queensland. The Initiative is a strategic response to mitigate the potential impacts of climate change, invasive species, land clearing and other environmental stresses on an area that contains high biodiversity. The Great Eastern Ranges corridor stretches over 3,600 kilometers and encompasses the longest adjoining mountain forests and woodland systems in Australia. Nearly two thirds of the threatened species and three quarters of the vegetation communities found in Australia are in the Great Eastern Ranges corridor.
Statewide project with the goal of linking existing patches of natural land, water, farms and ranches throughout the Florida Peninsula to create a corridor for dispersal of large mammals, continued flow of natural watersheds and protection of existing agricultural land. Fragmented patches of habitat created by urban development have isolated populations of wildlife and hindered movement of wide-ranging species such as panthers and bears. This project aims to increase awareness of how natural systems in Florida are used and how they can be linked to create an economically and environmentally sustainable ecosystem.
Y2Y is a multinational conservation region of 1.3 million square kilometers aimed at protecting land from the Yellowstone National Park region in Wyoming north to the Yukon Territory of Canada. The project goal is to maintain and restore key areas of habitat as well as corridors for connectivity with a focus on key species such as grizzly bears, caribou, lynx, golden eagles and native cutthroat trout. Y2Y seeks to ensure that wildlife populations remain genetically viable throughout the landscape, as well as harmoniously coexisting with human communities. Corridors are critical to maintain connectivity between habitat patches in such a large landscape, especially for species that migrate long distances such as trumpeter swans and species that range over large territories such as gray wolves.
The Terai Arc is a large region encompassing the border of Nepal and India. It covers 11 protected areas in India and Nepal and large non-protected areas between them. Among the non-protected areas are corridors and bottlenecks that are critical for wildlife movement between protected areas and for maintaining sufficient gene flow. These corridors are crucial for the long-term survival of endangered species that inhabit the region such as one-horned rhinoceroses, Asian elephants and Bengal tigers.
Panthera has launched the Jaguar Corridor initiative, which aims to link core jaguar populations within the human landscape from northern Argentina to Mexico. The jaguar is currently threatened throughout its range due to habitat loss and fragmentation, direct hunting by people, and lack of natural prey. Panthera’s plans include generating a map-based model of the jaguar’s ecological needs throughout its range, “ground-truthing” corridors to verify where jaguars are and where they are moving through, managing and conserving jaguar prey species, helping ranchers with livestock husbandry improvements, working with local communities to alleviate conflict, and assisting governments with protected area management.
The Appalachian National Scenic Trail runs over 2,000 miles between Georgia and Maine along the spine of the Appalachian Mountains. The Appalachian Trail’s protected corridor (a swath of land averaging about 1,000 feet in width) encompasses more than 250,000 acres, making it one of the largest units of the National Park System in the eastern United States. The corridor passes through some of the most significant and rare ecosystems remaining along the East Coast, and harbors more than 80 globally rare species. The protection of habitat within this corridor preserves connectivity between populations of not only rare species, but the hundreds of other species that persist only in this mountainous region.
