Book excerpt: The Northern Spotted Owl, a threatened species that occurs in coniferous forests in the western United States, has become a well-known environmental symbol. But how is the owl actually faring? This book contains the results of a long-term effort by a large group of leading researchers to document population trends of the Northern Spotted Owl. The study was conducted on 11 areas in the Pacific Northwest from 1985 to 2008, and its objectives were both to evaluate population trends and to assess relationships between reproductive rates and recruitment of owls and covariates such as weather, habitat, and the invasion of a closely related species, the Barred Owl. Among other findings, the study shows that fecundity was declining in five populations, stable in three, and increasing in three areas. Annual apparent survival rates of adults were declining in 10 out of 11 areas. This broad, synthetic work provides the most complete and up-to-date picture of the population status of this inconspicuous forest owl, which is at the center of the complex and often volatile debate regarding the management of forest lands in the western United States.

Book excerpt: Analyzes likely patterns of distribution & persistence of northern spotted owls on the Olympic Peninsula. Focuses on the effects of Federal habitat under provisions of the Northwest Forest Plan; additional benefits to the owl populations of different levels of habitat retention on non-Federal lands; effect of establishing a habitat connection between the Olympic Peninsula & other parts of the owl's range; the likely rate of habitat re-growth in the National Forest & its effect on the owl population; & the likely effect of a worst-case fire. A spatially explicit population model for northern spotted owls was used for the analysis. Reviews current information on demographics & likely owl population numbers on the Olympic Peninsula. Illustrations.
