Sequentially Observed Periodic Surveys of Management Compartments to Monitor Red-cockaded Woodpecker Populations
Management of the red-cockaded woodpeckcer (Picoides borealis) requires knowledge of size and trend of individual poulations. Periodic entry into management compartments for thinning and regeneration of stands provides considerable information on individual cavity trees and colonies. The statistical rationale and formulas for using this information to estimate population size and trend are presented. With additional field work, these data may provide better estimates of population size and trend than periodic random samples of compartments. In addition, estimates can be made yearly instead of at 5- to 10-year intervals.
