The clone number was not specified. Approximately 150 trees were felled. Recovery rates would presumably be higher for larger log sizes. This schedule was considered long and gentle and was intended to cause the least warping and shrinkage losses, a significant concern given the low density of hybrid poplar.
Hybrid poplar has a lower ratio of tangential to radial shrinkage than native cottonwoods.
Crook was the most troublesome type of warp while twist was the least. Overall, warp was considered moderate. Fuzzy grain was a problem in planing, however, the defect was easily removed by sanding. Hybrid poplar wood was easy to sand and compared well in defect-free percentage with other woods tested including lodgepole pine, white spruce, black cottonwood, red alder and aspen. Hybrid poplar rated as good or better than the wood species mentioned above for percentage of good to excellent shaping samples.
