Book Description
The Queen Maud Gulf Migratory Bird Sanctuary in Nunavut, in the central Canadian Arctic, is an important breeding area for a variety of species of waterfowl and other wildlife. An assessment of the types and spatial extent of land cover, with a particular emphasis upon wildlife habitat capability, has not been available for this sanctuary, preventing an adequate environmental assessment of proposed changes to the sanctuary's boundaries and limiting attempts to evaluate population trends and the distribution of wildlife species within the sanctuary. LANDSAT Thematic Mapper satellite imagery and digital image processing technology were used to prepare a land cover map for this large and remote area. Data from an examination of a variety of possible image enhancements, three field seasons of ground and aerial inspections of land cover types, and image classification were used to generate a thematic map of land cover types. An accuracy assessment of the classification provided an estimate of the reliability of the land cover map.

Book Description
Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world.

Book Description
Until now there has been no single, comprehensive resource on the status of North America's most threatened birds and what people can do to help protect them. Birder's Conservation Handbook is the only book of its kind, written specifically to help birders and researchers understand the threats while providing actions to protect birds and their habitats. Jeffrey Wells has distilled vast amounts of essential information into a single easy-to-use volume-required reading for anyone who loves birds and wants to ensure they are protected. At-a-glance species accounts cover in detail North America's one hundred most at-risk birds; each account is beautifully illustrated by today's top bird artists. The text includes status, distribution, ecology, threats, conservation actions and needs, and references. A distribution map accompanies each entry. Chapters discuss birds as indicators of environmental health, the state of North American bird populations, major conservation issues, and initiatives now underway to improve the health of North America's birds. Birder's Conservation Handbook is an indispensable resource for birdwatchers, researchers, naturalists, and conservationists. Reading it will inspire you to become an active steward of our birds and the habitats we share. A comprehensive guide to North America's one hundred most at-risk birds and how to protect them Compact and easy to use, with beautiful illustrations and data organized for convenient, at-a-glance reference Detailed species accounts, including distribution maps Practical advice on conservation Information on leading conservation agencies and resources
