Download or read book Herons Egrets and Bitterns written by Neil McKilligan and published by CSIRO PUBLISHING. This book was released on 2005-03-02 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to deal exclusively with the Australian members of the Family Ardeidae (herons, egrets and bitterns). It gives a comprehensive, easy-to-read account of their origins, classification and biology, and explains the features that distinguish them from other birds. The book devotes a major chapter to the 14 Australian species, covering their distribution and movements, feeding, breeding, population dynamics and conservation. Some of Australia’s herons have become very scarce in the southern half of the continent and are at risk of national or local extinction. In northern Australia heron habitats and resources are largely pristine and consequently this region accommodates large numbers of certain species. A final chapter on population and conservation provides a useful summary of the present status of the Australian herons, some of whom are thriving and others who are in a very precarious position.

Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 or read book Endangered and Threatened Species of the Platte River written by National Research Council and published by National Academies Press. This book was released on 2005-01-24 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.
