Glaze Damage In 13- To 18-Year-Old, Natural, Even-Aged Stands of Loblolly Pines in Southeastern Arkansas

Abstract

In late December 1998, a severe winter storm deposited 2.1 inches of precipitation on the Crossett Experimental Forest in southeastern Arkansas. Ice, in the form of glaze, accumulated on needles and branches of trees, and resulted in visual damage to sapling and pulpwood-sized pines. Within 60 days after the storm, damage was assessed within naturally regenerated, even-aged stands of loblolly pines (Pinus taeda L.) that ranged in age from 13 to 18 years. In all stands, >50 percent of pines were undamaged. When damage occurred in unthinned 13- and 18-year-old stands, pines were mostly affected by bending of the main stem. In thinned 15-year-old stands, damage was mainly in the form of branch loss. Stem breakage most often occurred when pines were 6 to 8 inches d.b.h. The probability of crown loss increased as d.b.h. increased; whereas, the probability of a bent main stem decreased with increasing d.b.h.
