Abstract
--Above ground biomass was de terrnined for yellowpoplar (Liriodendron tulipifera L.) t rees 6 to 28 inches d.b.h, growing in natural, uneven-aged mountain cove stands in western North Carolina. Average green weight of total t ree biomass without foliage ranged from 3 36 pounds for 6-inch t rees to 14,336 pounds for 28-inch trees. The average tree contained 91 percent of the total dry weight in the stem material, with 9 percent found in the branches. On the average, 23 percent of branch dry weight was bark and 7 1 percent was wood compared to stem material which contained 15 percent bark and 85 percent wood. Trends in biomass proportions a re discussed; and specific gravity, moisture content, and green weight per cubicf~ot data are presented for the total t ree and i ts components. Tables developed from regression equations show weight and volume of the total t ree and i ts components by d.b.h. and total height class.
