The Smithsonian Migratory Bird Center recently published a research article entitled "Using Demographic Attributes from Long-term Monitoring Data to Delineate Natural Population Structure".

We recommend managers define spatial units using natural populations when setting regional population objectives for both single and multi-species conservation plans.
