Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.

Available in PDF, EPUB and Kindle. Book excerpt: Periodic 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.

Download or read book The Atlas of Early Modern Wildlife written by Lee Raye and published by Pelagic Publishing Ltd. This book was released on 2023-07-18 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: What was the state of wildlife in Britain and Ireland before modern records began? The Atlas of Early Modern Wildlife looks at the era before climate change, before the intensification of agriculture, before even the Industrial Revolution. In the sixteenth to eighteenth centuries, beavers still swim in the River Ness. Isolated populations of wolves and lynxes linger in the uplands. Sea eagles are widespread around the coasts. Wildcats and pine martens remain common in the Lake District. In this ground-breaking volume, the observations of early modern amateur naturalists, travellers and local historians are gathered together for the very first time. Drawing on more than 10,000 records from across Britain and Ireland, the book presents maps and notes on the former distribution of over 160 species, providing a new baseline against which to discuss subsequent declines and extinctions, expansions and introductions. A guide to identification describes the reliable and unreliable names of each species, including the pre-Linnaean scientific nomenclature, as well as local names in early modern English and, where used in the sources, Irish, Scots, Scottish Gaelic, Welsh, Cornish and Norn. Raising a good number of questions at the same time as it answers many others, this remarkable resource will be of great value to conservationists, archaeologists, historians and anyone with an interest in the natural heritage of Britain and Ireland.

Download or read book The Ecology of Loch Lomond written by Kevin J. Murphy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Loch Lomond has long held a special place in the hearts of all the people of Scotland not only for its historic significance but also for the beauty of its countryside. Less widely known is the ecological importance of the area. It is the largest stretch of freshwater in Britain and the only loch to be crossed by the Highland Boundary Fault, one of the country's most important geological features. The University of Glasgow has recognized the importance of this loch situated so near the main campus and has operated a field station on its shores since 1948. In the mid-1960s the field station was re-established at Rowardennan as an all-year-round facility with laboratory and living accommodation for resident research workers and visiting field courses. In 1992 a symposium was held to celebrate the 25th anniversary of the opening of the new station and this volume presents the proceedings of that symposium and gives the state of the present knowledge of Loch Lomond. After an introduction to Loch Lomond, the papers are divided into three sections. Section I: The physical and chemical environment of Loch Lomond and its catchment. Section II: The biology and ecology of Loch Lomond and its catchment, and Section III: Issues affecting Loch Lomond and its catchment.
