Nebraska's Forest Resources in 2005


Book Description

Results of the 2005 annual inventory of Nebraska show an estimated 1.24 million acres of forest land. Softwoods comprise one-third of this forested area, with ponderosa pine being the primary component by acreage and volume. Hardwoods comprise more than half (58 percent) of all forested acreage. Overall, the elm/ash/cottonwood type is the predominant forest-type group in the state, comprising 26 percent of all forested land. In terms of volume, the estimate of net volume of all live trees and salvable dead trees on timberland increased from 1.71 to 1.74 billion cubic feet between the 1983 and 2005 inventories.




Nebraska's Forests, 2005


Book Description

Results of the first annual inventory of Nebraska's forests (2001-05) show an estimated 1.24 million acres of forest land; 1.17 million acres meet the definition of timberland. Softwood forest types account for one-third of all forest land area, with ponderosa pine being the most prevalent type. Hardwood forest types comprise 58 percent of Nebraska's forest land. Elm/ash/cottonwood is the predominant forest-type group in the State, accounting for 26 percent of all forest land area. Live-tree volume on timberland increased from 1.3 to 1.8 billion cubic feet between the 1994 and 2005 inventories. This report includes information on forest attributes, forest health, and agents of change: the introduction of nonnative invasive plants, insects and diseases, and the rapid expansion of eastern red cedar.

Illinois' Forest Resources, 2005


Book Description

Results of the completed 2005 Illinois annual inventory show an estimated 4.5 million acres of forest land that supports 7.6 billion cubic feet (ft3) of total net live-tree volume. Since 1948, timberland area has steadily increased and now represents 96 percent of total forest land. Growing-stock volume on timberland has risen to an estimated 6.8 billion ft3. Ten percent of live-tree volume on timberland is in cull trees. Live-tree aboveground biomass is 210.5 million dry tons. Net growth of growing stock increased by an average of 327 million ft3/yr. Growing stock was removed at an average of 60.6 million ft3/yr. Average annual mortality of growing stock was 86.6 million ft3/yr. Oak wilt, gypsy moth, emerald ash borer, Dutch elm disease, Asian longhorned beetle, and drought were among Illinois' forest health concerns.

20% Wind Energy By 2030


Book Description

In 2006, Pres. Bush emphasized the nation¿s need for greater energy efficiency and a more diversified energy portfolio. This led to a collaborative effort to explore a modeled energy scenario in which wind provides 20% of U.S. electricity by 2030. Members of this 20% Wind collaborative produced this report to start the discussion about issues, costs, and potential outcomes associated with the 20% Wind Scenario. The report considers some associated challenges, estimates the impacts, and discusses specific needs and outcomes in the areas of technology, manufacturing and employment, transmission and grid integration, markets, siting strategies, and potential environmental effects associated with a 20% Wind Scenario.
