DOWNLOAD EBOOKFor most British natural historians, there is one vertebrate order that could well be said to be “out of sight, out of mind.” This is our freshwater fishes, familiar principally only to anglers, those concerned with managing rivers and other waterbodies, and a few research scientists. The results of this project, which ran from 1998-2002, are published here in the form of comprehensive 10km square dot-distribution maps for the 54 species inhabiting England, Scotland, Wales, the Channel Islands and the Isle of Man. These indicate the vulnerability of several of our native British species. Following a wide-ranging introductory chapter, and further chapters on distribution and the history of the project, Chapter 4 comprises the individual species accounts under the headings: Description; Biology and behaviour; Habitat; Distribution in Britain; World distribution; Status; Hybrids and related species; and a final section of the relationship of each species with Man. In addition to a map, each species is illustrated by fine lithographs taken from Francis Day's famous 19th century work, skilfully supplemented by Michael J. Roberts for those species unknown to Day. Chapter 5 covers conservation and management of freshwater fishes and is followed by four Appendices relating to (1) Publications; (2 & 3) Legislation; and (4) Selected websites relating to environmental protection, biodiversity information and fish conservation. The book concludes with a Glossary; a comprehensive Bibliography; and an Index. In his Foreword, Sir John Burnett, Chairman of the National Biodiversity Network Trust, commends this books as “a unique reliable source of clear and comprehensive information that is pleasing both to the mind and to the eyes” and expresses the hope that “it will lead to ... the more effective conservation of this ‘alien race’ in our midst.” A joint project of the Environment Agency, the Centre for Ecology and Hydrology and the Joint Nature Conservation Committee; written by a team of 38 authors and compiled and edited by Cynthia Davies (CEH), Jonathan Shelley (EA), Paul Harding (Biological Records Centre, CEH), Ian McLean (JNCC), Ross Gardiner (Fisheries Research Services) and Graeme Peirson (EA).

DOWNLOAD EBOOKUnlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

DOWNLOAD EBOOKPeriodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland in The Changing Flora and Fauna of Britain, also edited by Professor David L. Hawksworth CBE. Now, in The Changing Wildlife of Great Britain and Ireland, he has gathered together some of the original and also new contributors to review changes since that time and look to the future. Contributions range from viruses, diatoms, fungi, lichens, mites and nematodes; through butterflies, dragonflies, flies and slugs; to flowering plants, ferns, mammals, birds and fish. The state of knowledge in different groups is assessed, and the effectiveness of statutory and other measures taken to safeguard wildlife considered. The picture is far from bleak, ameliorating sulphur dioxide levels have benefited sensitive lichens and mosses in a dramatic way, water quality improvement has been beneficial, there have been few certain extinctions and rediscoveries of species thought to have been lost. Biodiversity Action Plans have also benefited targeted species, but habitat restoration and management for some is not always good for others. But there are worrying trends in declining populations, with an increasing number being regarded as threatened or endangered, especially in agricultural areas, and where woodland management has changed, particular threats from introduced species, and concern over the effects of climate change. Some of the smaller organisms remain poorly known, a situation unlikely to change as expertise in many is scant or being lost. This stock-check and look to the future will be a key source book to conservationists, naturalists, and professional biologists for many years to come.
