Prescribed burning is one of the most valuable tools for the ecological and economic management of pine forests in the southeastern United States. There is concern, however, that burning may lead to excessive losses of nitrogen (N), thereby decreasing forest productivity. The deleterious effects of burning may be countered via N2-fixation by herbaceous legumes that typically thrive in burned ecosystems. However, the rates and controls of legume N2-fixation in these ecosystems are poorly understood. The goal of my research program is to gain an improved understanding of the N2-fixation rates, N fates, and environmental controls of herbaceous legumes in these ecosystems.
