Download Waiting for a Warbler Book in PDF, Epub and Kindle
Short listed for the Green Earth book award In early April, as Owen and his sister search the hickories, oaks, and dogwoods for returning birds, a huge group of birds leaves the misty mountain slopes of the Yucatan peninsula for the 600-mile flight across the Gulf of Mexico to their summer nesting grounds. One of them is a Cerulean warbler. He will lose more than half his body weight even if the journey goes well. Aloft over the vast ocean, the birds encourage each other with squeaky chirps that say, “We are still alive. We can do this.” Owen’s family watches televised reports of a great storm over the Gulf of Mexico, fearing what it may mean for migrating songbirds. In alternating spreads, we wait and hope with Owen, then struggle through the storm with the warbler. This moving story with its hopeful ending appeals to us to preserve the things we love. The backmatter includes a North American bird migration map, birding information for kids, and guidance for how native plantings can transform yards into bird and wildlife habitat.

Download Riparian Areas Book in PDF, Epub and Kindle
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Download Status of Pollinators in North America Book in PDF, Epub and Kindle
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
