Results are presented from a study on the ecology, population trends, food habits, and management of muskrats in Louisiana coastal marshes. As a management tool, prescribed burning: (1) prevents accumulation of "rough," which if accidentally ignited can do considerable habitat damage; (2) opens up dense vegetation, attracting waterfowl and making marsh travel easier; and (3) sets back succession so that preferred food species such as Olney bulrush can grow. The successional sequence following a deep, peat burn in a sawgrass marsh is described. [K-L-S]
