Effects of stump diameter and thinning treatments at different ages of copp
ice are described in terms of growth and yield of Emery oak (Quercus emoryi
) sprouts over a 5-year period. Growth and yield of residual sprouts depend
largely on the number of sprouts left after thinning, and the age of sprou
ts at thinning. Effects of stump diameter were inconclusive. Harvesting cyc
les for fuelwood might be reduced through proper timing of thinning.
