After pollination, scales of the female plants include mountainlaurel (Kalmia latifolia), flowering The qualities required for high grade sawtimber include; straightness, low taper, high wood density, small branches, high proportion of latewood, and no fewer than 4 growth rings in the last inch of radial growth.1,12 At age 40 the proportion of high-value pole size timber may be as high as 40 percent. the species' survival where other species decline. It persists in very dense stand conditions and responds to release thinning even when the trees are mature.6,13 Shortleaf tolerates competition longer than loblolly pine.
