Crown structure and growth efficiency of red spruce in uneven-aged, mixed-species stands in Maine

Maguire, Douglas A. (Douglas Alan); Brissette, John C.; Gu, Lianhong (NRC Canada, 1998)

Several hypotheses about the relationships among individual tree growth, tree leaf area, and relative tree size or position were tested with red spruce (Picea rubens Sarg.) growing in uneven-aged, mixed-species forests o ...
The effect of local stand structure on growth and growth efficiency in heterogeneous stands of ponderosa pine and lodgepole pine in central Oregon

Mainwaring, Douglas B.; Maguire, Douglas A. (Douglas Alan) (NRC Canada, 2004-11)

Basal area and height growth were analyzed for individual trees in uneven-aged ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex. Loud.) stands in central Oregon. Basal area ...
Impact of competitor species composition on predicting diameter growth and survival rates of Douglas-fir trees in southwestern Oregon

Bravo, Felipe; Hann, David W.; Maguire, Douglas A. (Douglas Alan) (NRC Canada, 2001)

Mixed conifer and hardwood stands in southwestern Oregon were studied to explore the hypothesis that competition effects on individual-tree growth and survival will differ according to the species comprising the competit ...
Predicting branch diameters on second-growth Douglas-fir from tree-level descriptors

Maguire, Douglas A. (Douglas Alan); Johnston, Stuart R.; Cahill, James M. (NRC Canada, 1999)

The quality of lumber and veneer recovered from logs of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is directly influenced by the maximum limb size attained on the crop tree. Because limb sizes are influenced by s ...
