GCJV population and habitat objectives are frequently derived in the face of substantial uncertainty, and models are frequently used to explicitly depict assumed population-habitat relationships. Focused research efforts are required to test the validity of those assumptions, and to determine impacts on bird species populations resulting from conservation actions on the ground. Results from research feed directly back into the GCJV conservation planning and evaluation loop, enabling population and habitat objectives to be continually adjusted as needed.

The GCJV works in concert with Gulf Coast universities, the U.S. Geological Survey, and GCJV partner organizations to design and undertake research to address the critical assumptions on which population and habitat objectives are based, and to evaluate management outcomes. These research projects are listed below.
