This science update contains the findings of a 2011 canvass of all primary wood-using plants in Georgia, and presents changes in product output and residue use since 2009. It complements the Forest Inventory and Analysis (FIA) annual inventory of volume and removals from the State’s timberland. The canvass was conducted to determine the amount and source of wood receipts and annual timber product drain, by county, in 2011 and to determine interstate and cross-regional movement of industrial roundwood. Only primary wood-using mills were canvassed. Primary mills are those that process...

Thousand cankers disease, caused by the walnut twig beetle (Pityophthorus juglandis Blackman) and an associated fungal pathogen (Geosmithia morbida M. Kolarõ´k, E. Freeland, C. Utley, and N. Tisserat), threatens the health and commercial use of eastern black walnut (Juglans nigra L.), one of the most economically valuable tree species in the United States. Effective phytosanitary measures are needed to reduce the possibility of spreading this insect and pathogen through wood movement. This study evaluated the efficacy of heat treatments and debarking to eliminate P. juglandis and G....

The forests in the Central Hardwoods Region will be affected directly and indirectly by a changing climate over the next 100 years. This assessment evaluates the vulnerability of terrestrial ecosystems in the Central Hardwoods Region of Illinois, Indiana, and Missouri to a range of future climates. Information on current forest conditions, observed climate trends, projected climate changes, and impacts to forest ecosystems was considered in order to assess vulnerability to climate change. Mesic upland forests were determined to be the most vulnerable to projected changes in climate,...

This science update summarizes the findings of the statewide annual inventory of the forest resource attributes in Texas conducted by the Southern Forest Inventory and Analysis (FIA) Program in cooperation with the Texas A&M Forest Service. The 254 counties of Texas are consolidated into seven FIA survey units—southeast (unit 1), northeast (unit 2), north central (unit 3), south (unit 4), west central (unit 5), northwest (unit 6), and west (unit 7). East Texas is made up of units 1 and 2 with a total of 43 counties, while central and west Texas consist of units 3 through 7 (fig. 1). This...

Early in the 20th century the deforestation resulting from the “golden-age of lumbering” left millions of acres of forest land in the need for reforestation. The challenge was so extreme that foresters of the early 1930s estimated that it would take 900 to 1,000 years at the then rate of planting to reforest the denuded forest land that occurred throughout the Nation. Forests of the West Gulf region were especially decimated due to the development and use of steam-powered logging equipment that left little capability for natural regeneration. Faced with this need, scientists of the...

In the U.S. forest products industry, wildfire is one of the leading causes of damage and economic losses. While individual wildfire behavior is well studied, new literature is emerging on broad-scale (e.g., county-level) wildfire risks. Our paper studies wildfire risks using crucial informational vari­ ables across both spatio units and time periods. Several statistical models are used to quantify the risks. We develop several maximum likelihood estimation methods to account for spatio-­ temporal auto-correlation in conditional risks. A group index insurance scheme is proposed, and its...
