As climate change begins to transform the environment in the United States and overseas, policymakers and environmentalists are realizing that the old paradigm of setting aside tracts of land or sea to preserve species that might otherwise disappear is no longer sufficient. It was an idea that worked in 1872, when one of the reasons cited for establishing Yellowstone National Park was to help preserve the few remaining buffalo. But as temperatures rise and animals and even plants migrate to more hospitable habitats, fixed boundaries set years ago no longer provide the protection some species need. Experts are exploring new strategies, focusing on such steps as protecting migration corridors, collecting and transplanting seeds, making sanctuary boundaries flexible and managing forests in novel ways.
...NOAA Assistant Administrator Richard W. Spinrad advocates creation of a national climate service to give agencies across the federal government better access to scientific projections so they can anticipate and plan for eventualities such as extended droughts and changes in water flows.
...Protecting wildlife, these experts say, can involve setting aside more land for species to migrate, protecting higher-elevation habitats that have lower temperatures and rooting out invasive species that threaten native ones.
...Interior Secretary Dirk Kempthorne created a climate change task force in March 2007 that outlined 80 climate policy options on Dec. 3; the Fish and Wildlife Service issued a more detailed draft climate plan less than two weeks later, urging the agency to find ways to connect broader landscapes and assess which species are at the highest risk because of global warming.
...Academics and conservation groups have just begun to calculate the costs of trying to protect landscapes and species in light of climate change. The Wildlife Federation has called on the government to set aside $7.2 billion annually for the next two decades to help natural resources in the United States adapt to global warming.
That should give you a flavor for what's coming.
When you start hearing about "flexible boundaries", and "protecting landscapes" and "migration corridors", you better get ready to lose your property.
