Assessing the potential for biomass energy development in South Carolina by Roger C Conner( )

3 editions published in 2009 in English and held by 285 WorldCat member libraries worldwide

An assessment of the potential for developing a sustainable biomass energy industry in South Carolina was conducted. Biomass as defined by Forest Inventory and Analysis is the aboveground dry weight of wood in the bole and limbs of live trees [greater or equal to] 1-inch diameter at breast height, and excludes tree foliage, seedlings, and understory vegetation. Several possible sources of biomass were analyzed: unutilized logging residue and standing residual inventory trees on acres with tree harvesting; commercial thinning; precommercial thinning on overstocked natural sapling-seedling stands; mill residue; and urban wood waste. A range of prices from $20 to $30 per ton was established by surveys sent to South Carolina's timber producers. Prices reflect 2008 market conditions. The estimates of potential biomass distributed across these price points rose from 4.8 million tons to a total of 16.5 million tons annually. Nearly 7.7 million tons are currently being utilized. New facilities that use wood to produce energy could capitalize on the 8.8 million annual tons of unutilized biomass and operate without overly impacting existing forest industries or increasing harvest levels above 2006 estimates
Historical trends of timber product output in the South by Tony G Johnson( )

2 editions published in 2008 in English and held by 278 WorldCat member libraries worldwide

Historical data of periodic canvasses of primary wood-using plants are presented for the 13 Southern States. They are Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia. Cubic-foot and standard volume tables are presented for production only. Production is the sum of timber harvested and used within a State, plus all roundwood exported to other U.S. States
Trends in southern pulpwood production, 1953-2006 by Tony G Johnson( )

2 editions published in 2008 in English and held by 268 WorldCat member libraries worldwide

Southern pulpwood production has increased nearly fourfold from 16.2 million cords (43.9 million green tons) in 1953 to 64.7 million cords (170.9 million green tons) in 2006. Softwood roundwood production more than doubled in the same time period; however, softwood production expressed as a proportion of the total production has declined from 87 percent in 1953 to 49 percent in 2006. In contrast, hardwood roundwood production and production from residues of all types substantially increased. The average daily pulping capacity of southern mills climbed from 28,670 tons per day in 1953 to 125,093 tons per day in 2006. Southern mills accounted for 70 percent of the Nation's total pulping capacity in 2006

Determining sample size for tree utilization surveys by Stanley J Zarnoch( )

3 editions published in 2004 in English and held by 263 WorldCat member libraries worldwide

"The U.S. Department of Agriculture Forest Service has conducted many studies to determine what proportion of the timber harvested in the South is actually utilized. This paper describes the statistical methods used to determine required sample sizes for estimating utilization ratios for a required level of precision. The data used are those for 515 hardwood and 1,557 softwood trees harvested in east Texas and classified into 5 product types. Two-stage sampling was used to collect the utilization data. The primary units were the logging operation locations and the secondary units were the trees within locations. The ratio of means estimator was used to calculate each of three utilization ratios. How ever, for simplicity, the mean of ratios approach was used to develop the statistical methodology for estimating sample sizes for a specified level of precision, defined as half the width of the 95-percent confidence interval. The infinite population model was used and variance components for the two-stage nested analysis of variance were obtained using PROC MIXED. The three utilization ratios were computed for all product classes for hardwoods and softwoods, as were the standard errors and 95-percent confidence intervals. The variance components were then obtained and used to develop tables that yield sample size scenarios based on specified levels of precision."
Estimates of biomass in logging residue and standing residual inventory following tree-harvest activity on timberland acres in the southern region by Roger C Conner( )

4 editions published in 2011 in English and held by 261 WorldCat member libraries worldwide

"This report provides estimates of biomass (green tons) in logging residue and standing residual inventory on timberland acres with evidence of tree cutting. Biomass as defined by Forest Inventory and Analysis is the aboveground dry weight of wood in the bole and limbs of live trees 1-inch diameter at breast height (d.b.h.), and excludes tree foliage, seedlings, and understory vegetation. Total timberland area with evidence of tree cutting averaged just over 6.0 million acres per year for all 13 Southern States over a 14-year period from 1994 to 2008. Final harvest was the primary type of cutting and averaged almost 2.3 million acres. Partial harvest and commercial thinning accounted for 1.8 million acres, and 1.7 million acres, respectively. As a result of annual tree cutting of all types in all 13 Southern States, a total of > 737 million green tons of residual biomass in standing live trees remained after harvesting. Of that volume, biomass in all-live residual inventory trees ( 1.0-inch d.b.h.) on final harvest acres amounted to nearly 457 million green tons. Biomass in rough and rotten trees from all other cutting combined totaled just over 280 million green tons. If recovered, this material could be used to help supply a biofuels industry in the South."

Results from this study showed that 86 percent of the total softwood volume measured was utilized for a product, and 14 percent was left as logging residue. Seventy-five percent of the total hardwood volume measured was utilized for a product, while 25 percent was left as logging residue."
Forest resources of east Oklahoma, 2008 by Richard A Harper( )

2 editions published in 2012 in English and held by 221 WorldCat member libraries worldwide

"The Forest Inventory and Analysis Program conducted the seventh survey of east Oklahoma forests. This was the establishment of the annual plot methodology and closeout of the prism remeasurement plots. Forest land area remained stable at 5.7 million acres and covered almost 57 percent of the land area. About 5.1 million acres of forest land was considered timberland and 86 percent of the timberland area was privately owned. Forest industry ownership, with 578,000 acres declined 45 percent and corporate ownership increased 557,000 acres. Softwood and hardwood inventory volume on timberland were at an alltime high with 1.6 and 3.5 billion cubic feet, respectively. Planted pine inventory volume increased 85 percent since 1992 and totaled 630 million cubic feet. Both softwood and hardwood total inventory increased to an alltime high suggesting a sustainable wood supply. Average annual net growth exceeds removals for softwood by 31 percent and hardwood by 43 percent. About 103,900 acres experienced some type of harvesting each year for this survey period (19932008). Estimated logging residues for the survey period averaged 14.7 green tons per acre with a potential recovery rate of 5.8 green tons per acre."
