Red squirrel (Tamiasciurus hudsonicus) population densities were studied on logged and unlogged plots in an Idaho Douglas-fir (Pseudotsuga menziesii) forest. Squirrel population densities were estimated before and after logging by using spot-mapping methods. In the unlogged forest, we estimated 0.75 to 1.25 individuals/ac, but in the second year after logging there were only 0.05 to 0.08 squirrels/ac. Red squirrel densities on logged study plots were less than one-fifth those on unlogged plots. West. J. Appl. For. 1:73-76 July 1986.

Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Western Journal of Applied Forestry covers the western United States, including Alaska, and western Canada; WJAF will also consider manuscripts reporting research in northern Mexico that has potential application in the southwestern United States.
