Maine's forests 2008

The second annual inventory of Maines forests was completed in 2008 after more than 3,160 forested plots were measured. Forest land occupies almost 17.7 million acres, which represents 82 percent of the total land area of Maine. The dominant forest-type groups are maple/beech/yellow birch, spruce/fir, white/red/jack pine, and aspen/white birch. Statewide volume equals 25.5 billion ft3, resulting from nearly 590 million ft3 of live-tree volume grown each year. The report also contains additional information on sustainability, biomass, carbon, forest health, land-use change, and timber products. The DVD includes detailed information on forest inventory methods, quality of estimates found, and tables forest statistics.

The Forests of Southern New England, 2007: A report on the forest resources of Connecticut, Massachusetts, and Rhode Island

This report summarizes the results of the fifth forest inventory of the forests of Southern New England, defined as Connecticut, Massachusetts, and Rhode Island, conducted by the U.S. Forest Service, Forest Inventory and analysis program. Information on forest attributes, ownership, land use change, carbon, timber products, forest health, and statistics and quality assurance of data collection are included. There are 5.1 million acres of forest land across the region; 60 percent of this forest land is in Massachusetts, 33 percent in Connecticut, and 7 percent in Rhode Island. This amount has decreased by 5 percent since the last inventory was completed in 1998. There are 2.6 billion trees on this forest land that have total volume of 12.6 billion cubic feet. Red maple and eastern white pine are the most common species in terms of both numbers of trees and volume. Fifty percent of the forest land is classified as the oak-hickory forest type.

West Virginia's Forests 2008

The first full annual inventory of West Virginias forests reports 12.0 million acres of forest land or 78 percent of the States land area. The area of forest land has changed little since 2000. Of this land, 7.2 million acres (60 percent) are held by family forest owners. The current growing-stock inventory is 25 billion cubic feet--12 percent more than in 2000--and averages 2,136 cubic feet per acre. Yellow-poplar continues to lead in volume followed by white and chestnut oaks. Since 2000, the saw log portion of growing-stock volume has increased by 23 percent to 88 billion board feet. In the latest inventory, net growth exceeded removals for all major species. Detailed information on forest inventory methods and data quality estimates is included in a DVD at the back of this report. Tables of population estimates and a glossary are also included.

This publication provides an overview of forest resource attributes for Connecticut based on an annual inventory conducted by the Forest Inventory and Analysis (FIA) program at the Northern Research Station of the U.S. Forest Service. These estimates, along with web-posted core tables, will be updated annually. For more information please refer to page 4 of this report.

Consequences of salinity and freezing stress for two populations of Quercus virginiana Mill. (Fagaceae) grown in a common garden1

Abstract Climate change is of increasing concern in coastal forests where rising sea levels could lead to dramatic shifts in ecosystem composition. To investigate how inundation may impact coastal ecosystems, we examined the sensitivity of Quercus virginiana Mill., a dominant tree in the southeastern U.S., to increased soil salinity and examined whether high salinity could increase its susceptibility to freezing damage (−10 °C). In a greenhouse, we examined the effect of three salt treatments (0–6 ppt) on acorn development and sapling physiology. We examined samples collected from two populations: inland Florida (FL) and coastal North Carolina (NC). We found that higher salt concentrations did not affect acorn germination, but did retard emergence. In the sapling stage, high salinity was more detrimental to plants from the FL population, causing greater declines in photosynthetic rates, water use efficiency, and dark quantum yield. FL plants also demonstrated a lower freezing tolerance than NC plants but freezing temperatures did not exacerbate effects of salt stress. Our data demonstrate important population-level differences in the salt and freezing tolerance of Q. virginiana. Since salt tolerance is important to the recruitment, growth, and survival of coastal Quercus species, this research can help with future conservation and management of this important species.

Missouri's forests 2008

The second full annual inventory of Missouris forests (2004-2008) reports more than 15 million acres of forest land, almost all of which is timberland (98 percent), with an average volume of more than 1,117 cubic feet of growing stock per acre. White oak and black oak are the most abundant in terms of live tree volume. Eighty-three percent of the States forest land is owned by private landowners. This report includes additional information on forest attributes, land use change, carbon, timber products,climate change, forest health, and the role of fire. A DVD included in this report includes 1) descriptive information on methods, statistics, and quality assurance of data collection, 2) a glossary of terms, 3) tables that summarize quality assurance, 4) a core set of tabular estimates for a variety of forest resources, and 5) a Microsoft Access database that represents an archive of data used in this report, with tools that allow users to produce customized estimates.

Iowa's Forests 2008

The second full annual inventory of Iowas forests (2004-2008) reports more than 3 million acres of forest land, almost all of which is timberland (98 percent), with an average volume of more than 1,000 cubic feet of growing stock per acre. American elm and eastern hophornbeam are the most numerous tree species, but silver maple and bur oak predominate in terms of live tree volume. Iowas forest land is comprised of 65 percent sawtimber, 19 percent poletimber, and 16 percent sapling/seedling or nonstocked size classes. Average annual net growth of growing-stock trees on Iowas timberland increased during the past decade to the current estimate of nearly 105 million cubic feet. This report includes additional information on forest attributes, land use change, carbon, timber products, and forest health. A DVD included in this report includes 1) descriptive information on methods, statistics, and quality assurance of data collection, 2) a glossary of terms, 3) tables that summarize quality assurance, 4) a core set of tabular estimates for a variety of forest resources, and 5) a Microsoft Access database that represents an archive of data used in this report, with tools that allow users to produce customized estimates.

North Dakota's forests 2005

The second annual inventory of North Dakotas forests reports more than 772,000 acres of forest land with an average volume of more than 921 cubic feet per acre. Forest land is dominated by the bur oak forest type, which occupies more than a third of the total forest land area. The poletimber stand-size class represents 39 percent of forest land, followed by sawtimber (32 percent) and saplings/seedlings (28 percent). The volume of growing stock currently totals more than 341 million cubic feet. The average annual net growth of growing stock on forest land from 2006 to 2010 was approximately 6.8 million cubic feet per year. This report includes additional information on forest attributes, land use change, carbon stocks, timber products, forest health, and statistics, methods, and quality assurance of data collection.

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.

Forest resources within the Lake States ceded territories 1980 - 2013

The Lake States ceded territories are the portions of northern Michigan, northeastern Minnesota, and northern Wisconsin that were ceded by tribes of the Ojibwe to the government of the United States of America in the treaties of 1836, 1837, 1842, and 1854. The tribes retain rights to hunt, fish, and gather in the 1837, 1842, and 1854 treaty areas. This report summarizes the results of a series of forest inventories in the region between 1980 and 2013. Inventory results show the region has 30.7 million acres of forest land with forests covering 65.3 percent of the total land area. Forest features reported here focus on the status of six species of trees (sugar maple, black ash, paper birch, northern white-cedar, hophornbeam, and balsam fir) that have special historic and cultural value to the Ojibwe, in addition to the standard reporting of volume, biomass, growth, removals, and mortality of all trees that are typically included in the state-level reports produced by the Forest Inventory and Analysis program of the U.S. Forest Service. Sections of this report also focus on carbon, standing dead trees, invasive plant species, and ground flora.
