Produktbeschreibung
The 3rd edition of Amphibians of Oregon, Washington and British Columbia underscores the continuing shrinkage of habitat for the 36 species of amphibians that can be found in the Pacific Northwest and reveals that a growing number of species are being stressed by environmental changes. In fact, more than half the species native or introduced to the region, including the Oregon Spotted Frog and Northern Leopard Frog, are now listed as either endangered or at risk. The Red-legged Frog is listed as a 'species of concern' in all three jurisdictions. One species, unfortunately, has prospered all too well. The larger and more aggressive American Bullfrog was introduced to the Northwest in the 1920s or '30s as a possible human food source and has since out-eaten and out-competed native amphibians throughout much of the region. This outstanding collection of photographs, illustrations and field notes remains an essential resource for both professional and amateur naturalists.
