Evaluating changes in yellow-poplar management in response to new low-end markets
1998
Pelkki, M.H. | Arthaud, G.J.
Optimal rotation length and thinning schedules for yellow-poplar were determined through the use of a dynamic programming simulation system. Economic and management responses to changing low-end markets for roundwood yellow-poplar were investigated as well as sensitivity to real price increases, interest rates, and number of allowed thinnings in a rotation. It was found that strong markets for low quality and small diameter yellow-poplar shorten rotation lengths and shift low-quality sawtimber into the roundwood markets. In all cases, improvement thinnings were shown to be a valuable thinning strategy and, in many cases, improvement thinning combined with a thinning from above produced the highest financial returns.
