| Summary |
"North America's freshwater habitats and the extraordinary biodiversity they contain are facing unprecedented threats from a range of sources, including flow alteration, habitat fragmentation, introduced species, and overall land use changes."--BOOK JACKET. "World Wildlife Fund-U.S. assembled a team of leading scientists to conduct a conservation assessment of freshwater ecoregions as an initial step in identifying the areas where protective and restorative measures should be implemented first. Freshwater Ecoregions of North America presents that assessment and outlines measures that must be taken to conserve, and in many cases restore, native biodiversity."--BOOK JACKET |
