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.

This book was released on 2007 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document contains nine FAO commissioned papers on cage aquaculture including a global overview, one country review for China, and seven regional reviews for Asia (excluding China), northern Europe, the Mediterranean, sub-Saharan Africa, Latin America and the Caribbean, northern America and Oceania. The content of the papers is based on the broad experience and sound knowledge of the authors with advice and help received from many experts and reviewers around the globe. The papers were presented to a distinguished audience of some 300 participants from over 25 countries during the FAO Special Session on Cage Aquaculture - Regional Reviews and Global Overview at the Asian Fisheries Society (AFS) Second International Symposium on Cage Aquaculture in Asia (CAA2), held in Hangzhou, China, from 3 to 8 July 2006.

Available in PDF, EPUB and Kindle. Book excerpt: " ... The purpose of the Strategy is to establish a strategic framework for action, to conserve and sustainably use and manage New Zealand's biodiversity. The primary focus is on New Zealand's indigenous biodiversity. However, because of the value and economic importance of much of our introduced biodiversity, the conservation of the genetic resources of our important introduced species is also addressed."--Executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: Measuring and Monitoring Biological Diversity is the first book to provide comprehensive coverage of standard methods for biodiversity sampling of amphibians, with information on analyzing and using data that will interest biologists in general. In this manual, nearly fifty herpetologists recommend ten standard sampling procedures for measuring and monitoring amphibian and many other populations. The contributors discuss each procedure, along with the circumstances for its appropriate use. In addition, they provide a detailed protocol for each procedure's implementation, a list of necessary equipment and personnel, and suggestions for analyzing the data. The data obtained using these standard methods are comparable across sites and through time and, as a result, are extremely useful for making decisions about habitat protection, sustained use, and restoration—decisions that are particularly relevant for threatened amphibian populations.

Download or read book Braided River Ecology written by Duncan Peter Gray and published by Science & Technical Publishing Department of Conservation. This book was released on 2007 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A braided river is one that, over some part of its length, flows in multiple, mobile channels across a gravel floodplain. In New Zealand, many braided rivers remain in a relatively unmodified condition, but increasing demands for hydro-electricity generation, irrigation, gravel extraction and flood protection works are placing pressure on these systems. However, apart from a limited number of studies on the ecology of individual species or reaches, there has been little coordinated ecological research to assess the overall values and function of braided river ecosystems in New Zealand. This review summarises the international and New Zealand literature on braided rivers, with particular emphasis on benthic invertebrate ecology. Braided rivers typically experience short-term channel migration within the active bed and greater lateral channel migration across the entire floodplain in the longer term. Channel migration occurs because steep headwater tributaries supply highly variable discharges and mobile erodable substrates to the mainstem. Braided rivers typically possess extended floodplains, which may contain a mosaic of floodplain habitats ranging from highly unstable main-stem channels to stable spring complexes. Main channel aquatic invertebrate communities are frequently low in diversity and dominated by the leptophlebiid mayfly Deleatidium spp., but also chironomids and elmid beetles. In contrast, floodplain springs can have highly diverse communities rich in amphipods, mayflies, caddis, snails and chironomids. Groundwater and floodplain pond habitats also occur frequently and can contain several specialist taxa. Braided rivers and their floodplains are spatially complex, temporally dynamic habitats with high landscape- and reach-scale biodiversity values. The challenge facing managers is to protect this biodiversity within the context of increasing human demands on the rivers. This report highlights the particular threats and management issues associated with braided rivers in New Zealand and identifies areas where future research is required.

Download or read book Groundwaters of New Zealand written by Michael R. Rosen and published by . This book was released on 2001 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwaters of New Zealand is the definitive new source for information on the groundwater resources of New Zealand. Written by many of New Zealand's leading experts, the book covers varied aspects of groundwater research, assessment, use, and management in New Zealand. This book is divided into two parts. The first part documents the history of groundwater development in New Zealand, and current research on interactions between groundwater systems and other components of the hydrological cycle such as health, processes (recharge and groundwater-surface water interaction) and techniques (isotopic methods). The second part of the book provides up-to-date regional summaries of groundwater resources and quality in every region of the country. Groundwater quality is explored in chapters on groundwater chemistry and microbiology, and the health aspects of groundwater. The book also contains detailed regional summaries, covering the location, use, quality, and management of groundwater resources, for the entire country.This book will be the essential reference text for all environmental, engineering, and resource management professionals working with groundwater, and students of the many scientific and engineering disciplines that contribute to groundwater investigations. Many groundwater users, both practicing and in school will find this book a valuable reference that adds significantly to their understanding of groundwater resources.-back cover.
