Warming Trends Alter Conservation

Excerpts:

At the Blackwater National Wildlife Refuge on Maryland's Eastern Shore, sea-level rise threatens to drown the brackish marsh on which migrating shorebirds depend. In Northern California, the shrinking snowpack has reduced stream flows that sustain the delta smelt, a federally threatened fish species. Higher summer temperatures in northern Minnesota have depressed the birthrates of the area's once-populous moose, and just 20 inhabit the Agassiz National Wildlife Refuge that was designed in part to shelter them.

…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.
