Science: Research and Stewardship

Mark Woodrey, Ph.D.

Research Coordinator

With clapper rail

Mark is a research biologist at the Mississippi State University Coastal Research and Extension Center and serves as the Research Coordinator at the Grand Bay NERR. Trained as an ornithologist, he is currently studying ecology of tidal marsh birds and using marsh birds as an indicator of restoration success. In addition, his collaborative research efforts focus on human impacts on coastal habitats, the effects of global climate change on coastal plants and animals, ecosystem effects of mercury, and the role of terrestrial vertebrates in tidal marshes. Ultimately, Mark’s goal is to better understand coastal ecosystems to allow natural resource managers to make more informed conservation decisions.


Jonathan Pitchford, Ph.D.

Stewardship Coordinator

Holding Distichlis

Jonathan Pitchford is the Stewardship Coordinator at the Grand Bay NERR. He holds a B.S. in Zoology from Auburn University, an M.S. in Biology from Appalachian State University, and a Ph.D. in Natural Resource Science from West Virginia University. He has been involved in a variety of ecological research projects from studying the spatial distribution of bottlenose dolphins and sea turtles in the Mississippi Sound to understanding the effects of wetland restoration in West Virginia. Jonathan joined the NERR team in 2016 and is working closely with Stewardship and Research staff to understand long-term changes in NERR resources through the “Sentinel Site Program” and to implement and monitor restoration of aquatic and terrestrial habitats. He also enjoys working with Education and Outreach staff to communicate the purpose of long-term monitoring and the principles of stewardship to school groups and the public. Jonathan hails from Abbeville, AL and is an avid fan of the Auburn Tigers…War Eagle!


Kim Cressman

SWMP Coordinator

Holding sonde- water quality equipment

Kim is experienced in analyzing the water quality of both freshwater and coastal ecosystems. At Grand Bay NERR, she coordinates sampling and data management for the System-Wide Monitoring Program (SWMP). Through SWMP, the nation’s 29 NERRs each use the same standard protocols to collect water quality, nutrient, and meteorological data. This allows consistently high-quality data to be accumulated over long periods of time, compared within and across regions, and used to inform coastal resource management decisions.
