Cooperative Fish and Wildlife Research Units Program: North Carolina
Education, Research and Technical Assistance for Managing Our Natural Resources

North Carolina Technical Assistance Activities

As part of our mission, NC Unit scientists routinely provide technical assistance to cooperators, colleagues, and the public, ranging from data analysis support, GIS mapping, workshops, and consultations on a variety of natural resource issues. For example, North Carolina Unit scientists provide assistance with stock assessments for the North Carolina Division of Marine Fisheries, strategic habitat planning for the U.S. Fish and Wildlife Service, and serve on the non-game advisory committee for the North Carolina Wildlife Resources Commission. They conduct workshops and training for natural resource professionals and serve as expert panelists and witnesses on a variety of topics.
