Abstract
In their remarks on the study of Spotted Owls (Strix occidentalis) by Carey et al. (1992). Rosenberg et al. (1994) questioned the appropriateness of certain analyses and methods, and specific interpretation of the results. Herein, I respond to the comments of Rosenberg et al. (1994), which are summarized in italics.Sample sizes were nor clear. Twenty 20-ha grids (11 in old, 9 in young forest) and 27 4-ha transects (young forest) in Oregon and 14 20-ha grids (6 in old, 8 in young forest) in Washington were trapped (Carey et al. 1992:225©¤228). Only woodrats (Neoroma spp.) were trapped on transects. The 20 Oregon grids were trapped 1©¤9 seasons each; for the 16 trapped ¡Ý 3 times, each season was reported (Carey et al. 1992:Table 5); 80 estimates of flying squirrel (Glaucomvs sabrinus) densities were made.
