Deer Forage in Hardwood Stands following Thinning and Fertilization

We conducted a 10-year study in oak-hickory stands in the Arkansas Ozarks to investigate the effects of intermediate thinning and nitrogen (N) fertilization on the annual production of understory vegetation. A total of 101 experimental plots was thinned to residual overstory densities of 40%, 60%, 80%, or 100% of full stocking. Nitrogen fertilizer (336 kg N/ha) was applied to a subset of plots in each thinning treatment. Understory species composition and biomass were estimated 1, 2, 3, 5, and 10 years after treatment. Thinning and fertilizing increased (P < 0.01) the total biomass of...
