The overall goal of the SOPN landbird monitoring program was to report biologically significant changes in population parameters over report time. Three primary monitoring objectives that are complementary and together provide a comprehensive assessment of changing bird populations and communities include occupancy, bird species richness and composition, and density.

The overall goal of the SOPN landbird monitoring program is to detect biologically significant changes in population parameters over time. This collaborative program is intended to maximize the strength of inferences within the context of finite resources. Three primary monitoring objectives include occupancy, bird species richness and composition, and density.
