Margaret Fields is the GIS Manager at the North Carolina Chapter of The Nature Conservancy, doing spatial analysis to support various projects around the state. Most recently she has performed a model to examine nutrient inputs in the Cape Fear River, mainly in the coastal plain. This area is dominated by agriculture, as well as forestry and some urban areas. These results are being used to examine the feasibility of a water fund for the Wilmington area at the mouth of the river. Margaret received a BA from Davidson College in 1991, and has been working for the North Carolina Chapter for 19 years, going where GIS takes her as far as learning. Other work activities include dealing with invasive species issues and controlled burning. When not at work, Margaret does her share of biking, hiking, paddling, gardening, and helping her boyfriend Matt envision and build unique structures in the yard.
