Abstract
Distributions of native salmonid fish in the Pacific Northwest are strongly tied to temperature conditions in their habitat. Salmonid populations have declined in conjunction with thermal changes and the loss and fragmentation of large and interconnected cold-water habitats. Temperature affects the health of not only individual fish but also entire populations and groups of species. Temperature changes have obvious direct effects, and also interact with other factors to indirectly affect salmonids. This paper is not intended to be an exhaustive review of the status or declines in salmonid populations or distributions. These are widely documented elsewhere. We briefly review some examples of declines in salmonid populations and habitats to provide some context for these issues, but our focus is not on declines per se. Furthermore, this issue paper is not intended to be an exhaustive review of the effects of temperature on salmonid distributions in the Pacific Northwest (see McCullough 1999). Rather, it is intended to describe a basic framework for thinking about salmonid distributions and appropriate biological criteria to protect salmonid populations from adverse effects of altered factors affecting thermal regimes. 1. Definition of a 'distribution; 2. Direct effects of temperature; 3. Indirects effects of temperature; 4. Relevance of scale; and 5. Importance of unoccupied habitat.

Contents Notes
"The technical workgroup developed five technical summaries on the major physical and biological considerations for developing water temperature standards: 1. thermal effects on salmonid physiology, 2. thermal effects on salmonid behavior, 3. interactions between multiple stressors... affecting salmonids, 4. thermal influences on salmonid distribution, and 5. spatial and temporal variation in patterns of stream temperature." -- Preface.
