Ponderosa Pine Basal Area and the Kaibab Squirrel
Mark-recapture methods were used to determine an index to the minimum number of Kaibab squirrels for nine trapsites. Squirrel numbers were correlated with forest characteristics, including number, basal area, and volume per acre of five tree species, and numbers of squirrel nests per trapsite. Most consistently associated with the Kaibab squirrel index was basal area of ponderosa pine, including all ponderosa pine and ponderosa pine greater than 6 inches dbh. A conceptual model for assessing quality of squirrel habitat was formulated by ranking basal area per acre of all ponderosa pine and number of squirrel nests per trapsite.
