National workshop convened to review the latest techniques available to quantify relationships between habitat features and fish production. The workshop focused on salmonids because of their importance on both the Atlantic and Pacific coasts, but effects on other non-salmonid populations were included since data is scarce in some areas. Coverage included methodologies for the quantification of the effects of habitat alteration on yield, empirical examples of the effects of physical and chemical habitat changes on stocks, and the permissable degree of extrapolation in assigning effects of habitat alteration to a stock.

Management of Anadromous Fish Habitat on Public Lands represents a watershed approach to managing public lands in Alaska, California, Idaho, Oregon, and Washington. The document summarizes the past management history and the amount and condition of riparian and aquatic components of watersheds containing anadromous fish for each state. The report, separated into three regions (coastal, Columbia and Alaska), outlines the critical components of successful management for these areas. Management actions, including establishing riparian reserves, conducting watershed analysis, and identifying key watersheds and watershed restoration activities, are needed to conserve and restore remaining wild stocks of anadromous salmonids.

Whether tributary habitat improvements have achieved, or are likely to achieve, the goal of recovering conditions favoring the production of salmonids in the Columbia River Basin is unclear. This report reviews the approaches, assessment procedures, and implementation strategies for habit improvement. It examines topics central to the recovery of tributary habitat: (1) the biological objectives related to habitat recovery; (2) the strategies for implementing restoration; (3) the incentives for implementing restoration; (4) the scientific foundation for habitat recovery; and (5) monitoring and evaluation. This review answers the question: What concepts and strategies should be incorporated in habitat recovery actions to improve their chances for success? Illus.

Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).

The vast temperate rainforests of coastal British Columbia are world renowned, but much less is known about the other rainforest located 500 kilometres inland along the western slopes of the interior mountains. The unique integration of continentality and humidity in this region favours the development of lush rainforest communities that incorporate both coastal and boreal elements. This book brings together, for the first time, a broad spectrum of information about the ecology, management, and conservation of this distinctive ecosystem. Accessibly written and generously illustrated, the chapters examine the physical, social, economic, and ecological dimensions of the rainforest. They also look at how the delicate balance of this ecosystem has been threatened by human use and climate change. In the past, governments encouraged the forest industry to clearcut the “decadent” old stands and replace them with rapidly growing young trees of other species. More recently, out of concern for the ecological consequences of such practices, researchers have begun to examine alternative management strategies. This book offers a vision that combines various strategies in order to balance the conservation of the inland rainforest as a fully functioning ecosystem with human use of its diverse resources.
