DOWNLOAD EBOOKResults 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.

DOWNLOAD EBOOKThe first full, annualized inventory of Illinois' forests reports more than 4.5 million acres of forest land with an average of 459 trees per acre. Forest land is dominated by oak/hickory forest types, which occupy 65 percent of total forest land area. Seventy-two percent of forest land consists of sawtimber, 20 percent contains poletimber, and 8 percent contains sapling/seedlings. The volume of growing stock on timberland has been rising since 1948 and currently totals 6.8 billion cubic feet. The average annual net growth of growing stock from 1998 to 2005 is 327 million cubic feet per year. Additional information on forest attributes, changing land use patterns, timber products, and forest health is included in this report.

In Illinois, periodic inventories were completed in 1948, 1962, 1985, and 1998 (Essex and Gansner 1965, Raile and Leatherberry 1988, Schmidt et al. 2000, Central States Forest Experiment Station 1949).

Forest land is dominated by oak/hickory and elm/ash/cottonwood forest-type groups, which occupy 93 percent of total forest land area. The volume of growing stock on timberland totals 7.2 billion cubic feet. The average annual net growth of growing stock from 2001-2005 to 2006-2010 averages 215.1 million cubic feet per year. This report includes additional information on forest attributes, land-use change, carbon, timber products, and forest health. The included DVD contains 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."--Abstract.
