Production-Rating Functions for Abert Squirrels in Southwestern Ponderosa Pine
Ffolliott PF and Patton DR. 1975. Production-Rating Functions for Abert Squirrels in Southwestern Ponderosa Pine. Wildlife Society Bulletin. 3(4):162-165
Production-rating functions for Abert squirrel (Sciurus aberti) food and nest trees for ponderosa pine (Pinus ponderosa) tree volume were plotted against one another to form decision-making models for identifying conflicts between use. The graphs show competitive stages, where the value of one improves while the other declines. Since the value scales for both uses are not available, a land manager must use subjective judgments in deciding optimum tree size for both. The tecnhique of using production-rating functions, nonetheless, has advantages for land managers.
