Publication Date

This NSST technical report introduces a new method for translating continental waterfowl population goals into regional targets for each Joint Venture, using eBird citizen science data in place of harvest and survey-based approaches. It offers Joint Ventures a transparent, consistently documented option for setting nonbreeding season population objectives tied directly to NAWMP goals.
