Abstract
The effects of prescribed burs on the quantity and quality of deer (Odocoileus virginianus) browse were studied during March, 1966, 1967, and 1968, on the Catoosa Wildlife Management Area, Tennessee. The 1968 burn contained slightly less available browse than the unburned site. Burns made during 1967 and 1966 showed increases of 425.3 and 757.5 lb of green browse per acre, respectively, when compared with the unburned study area. A qualitative study of three browse species, red maple (Acer rubrum), sourwood (Oxydendrum arboreum), and sassafras (Sassafras albidum), showed no significant effects of burning on nutritive values. Potassium and phosphorus content of the browse species was highest in June and lowest in September and January. No seasonal trend was noticed in sodium content. Calcium content was lowest in June and increased in content during September and January.
