Figure 2.20. (a) view of a typical exclosure and surrounding marsh at Salt Flats in early July 1978; midway in the growing season 8 months after grazing by greater Snow Geese. Note very dense spartina alterniflora growing within the exclosure and relatively little growing outside it. (b) the same exclosure approximately 7 weeks later. Grass outside the exclsoure had grown taller, but not denser (after Smith & Odum 1981). Printed with permission.
