    Description

    Results for several major stand level variables from a 7-year-old yellow-poplar (Liriodendron tulipifera L.) plantation established in a converted pasture in northern West Virginia were summarized based on initial planting densities of 1,517 trees/ac, 972 trees/ac, 765 trees/ac, and 602 trees/ac. Stand basal area/acre at age 7 was greatest (54.7 ft2/ac) for the 4 ft spacing and least (22.1 ft2/ac) for the 10 ft spacing. Average total height for all trees was similar for all spacing treatments except for the 10 ft spacing which was approximately 6 ft shorter at age 7. Based on locally fit logarithmic weight and volume equations, total aboveground green weight and dry weight decreased with an increase in planting density, with the greatest being the 4 ft spacing treatment averaging 26.3 and 10.8 tons/ac, respectively. Outside bark bole volume ranged from 228 to 769 ft3/ac, while bole green weight ranged from 6.4 to 22.7 tons/acre, depending on planting density.
