These include the EPA, US Forest Service, US National Park Service, US Fish and Wildlife Service, The Sierra Club, National Wildlife Federation, Natural Resources Defense Council, The Nature Conservancy, Society for Conservation Biology, and many others. The IUCN is also one of the primary promoters and developers of the Convention on Biological Diversity . This perhaps explains why federal agencies and environmental organizations appear to be working in concert to implement the Wildlands Project and Biodiversity Treaty even though the treaty has not been ratified. The map incorporates, when available, actual maps as well as a multitude of government and environmental literature demanding various reserves or national parks interconnected with corridors. And grand it is.
Core reserves are wilderness areas that supposedly allow biodiversity to flourish.
All roads should be permanently closed. Multiple corridors interconnecting a network of core reserves provide functional redundancy and mitigate against disturbance. . . . Corridors several miles wide are needed if the objective is to maintain resident populations of large carnivores. While this effort has a noble mission, the implications are staggering. Half of a region in wilderness is a reasonable guess of what it will take to restore viable populations of large carnivores and natural disturbance regimes, assuming that most of the other 50 percent is managed intelligently as buffer zone.
