West Virginia Forests 2013

The annual inventory of West Virginias forests, completed in 2013, covers nearly 12.2 million acres of forest land with an average volume of more than 2,300 cubic feet per acre. This report is based data collected from 2,808 plots located across the State. Forest land is dominated by the oak/hickory forest-type group, which occupies 74 percent of total forest land area. Seventy-eight percent of forest land area consists of a plurality of large diameter trees, 15 percent contains medium diameter trees, and 7 percent contains small diameter trees. The volume of growing stock on timberland has been rising since the 1950s and currently totals over 25 billion cubic feet. The average annual net growth of growing-stock trees on timberland from 2008 to 2013 is approximately 519 million cubic feet per year. Important species compositional changes include increases in sapling numbers of yellow-poplar, American beech, and noncommercial species, which coincide with decreases in numbers of trees and saplings of oak species. Additional information is presented on forest attributes, land use change, carbon, timber products, species composition, regeneration, and forest health. Detailed information on forest inventory methods, data quality estimates, and summary tables of population estimates, are available at http://dx.doi.org/10.2737/NRS-RB-105.

Forests of Vermont and New Hampshire 2012

The first full remeasurement of the annual inventory of the forests of Vermont and New Hampshire was completed in 2012 and covers nearly 9.5 million acres of forest land, with an average volume of nearly 2,300 cubic feet per acre. The data in this report are based on visits to 1,100 plots located across Vermont and 1,091 plots located across New Hampshire.

Seventy-four percent of the forest land area is in large diameter stands, 12 percent in medium diameter stands, and 13 percent in small diameter stands. The volume of growing stock on timberland has been rising since the 1950s and currently totals 811 million cubic feet. Between 2008 and 2013, the average annual net growth of growing-stock trees on timberland was approximately 16 million cubic feet per year. Additional information is presented on forest attributes, ownership, carbon, timber products, species composition, regeneration, and forest health.

Indiana timber industry, 2013

This resource update provides an overview of timber product output (TPO) and use in Indiana based on questionnaires designed to determine the size and composition of the States primary wood-using industry, its use of roundwood, and its generation and disposition of wood residues. This study was a cooperative effort between the Indiana Department of Natural Resources (IN DNR) and the Forest Inventory and Analysis (FIA) unit at the Northern Research Station (NRS) of the USDA Forest Service. IN DNR surveyed all known primary wood-using mills and FIA processed and analyzed the survey responses. This update presents results from the 2013 survey with comparisons to the 2008 and 2005 surveys. The data were accessed from the FIA database in December 2016. Certain terms used in this report—retained, export, import, production, and receipts—have specialized meanings and relationships unique to the FIA program that surveys timber product output.

Wisconsin Forests 2014

This report summarizes the third annual inventory of Wisconsin’s forests, conducted 2009–2014. Wisconsin’s forests cover 17.1 million acres with 16.6 million acres classified as timberland. Forests are bountiful in the north with Florence, Forest, Menominee, and Vilas Counties having over 90 percent forest cover. In the southeastern part of the State, forest cover is lowest with Dodge, Fond du Lac, Milwaukee, and Racine Counties having less than 10 percent forest cover. The sawtimber volume on timberland has been rising and is estimated to be 69.5 billion board feet. Oak/hickory is the predominant forest-type group, covering one-quarter of the forest land. The statewide growth-to-removal ratio on timberland is 2.2, indicating growth is outpacing removals. Additional information on Wisconsin’s forests such as growth, mortality, species composition, ownership, diseases, invasive plant species, and forest economics is detailed in this report.

Iowa Forests, 2013

The third full annual inventory of Iowas forests (2009-2013) indicates that just under 3 million acres of forest land exists in the State, 81 percent of which is in family forest ownership. Almost all of Iowas forest land is timberland (96 percent), with an average volume of more than 1,000 cubic feet of growing stock per acre on timberland and more than 1,500 cubic feet of all live volume (for trees at least 5 inches diameter at breast height) per acre on timberland. American elm and eastern hophornbeam are the most numerous tree species, but bur oak and silver maple predominate in terms of live-tree volume. Iowas forest land is composed of 70 percent sawtimber, 17 percent poletimber, and 13 percent sapling/seedling or nonstocked size classes. Average annual net growth of growing-stock trees on Iowa’s timberland decreased during the past decade to the current estimate of 71 million cubic feet.
