摘要：

For Strix occidentalis caurina, sampling yielded a crude density of 0.235 owls/km2 (95% CI = 0.214-0.256) and ecological densities of 0.544 (0.495-0.592) and 0.660 (0.601-0.719) owls/km2 of suitable habitat (2 definitions). Increases in density over 4 yr were attributed to population processes, such as immigration. Densities were relatively high when compared with other populations. Estimates from this study and the US Forest Service indicate a 60.0-82.5% reduction of current spotted owl populations on at least 1 National Forest under current management plans by the US Forest Service. -from Authors
