A study was made of net primary productivity of salt marsh communities in a 2000-acre, regularly flooded marsh in Brunswick County, North Carolina. Color infra-red aerial photographs were used to determine acreages of community types. Net primary productivity estimates were based on harvest method data. Observed harvest data were fitted to a fourth degree polynomial in time in order to express the average behavior of the standing crop through the year. Net productivity was determined by two methods: Use of living standing crop only, and Use of changes in living and dead standing crop. Over the entire marsh net primary productivity was estimated to be 1534 kcal/m sq/yr. These values were lower than similar values from Georgia but resembled closely other estimates of net primary productivity for salt marsh vascular plants in North Carolina.
