Aprašymas

This report presents Iowa's annual inventory results for 2005. Estimates show that Iowa has more than 2.8 million acres of forest land. Total live-tree volume on forest land is 4.0 billion cubic feet (ft3). Ninety-eight percent of forest land is classified as timberland. Oak/hickory is the predominant forest-type group, representing 54 percent of timberland area. Growing-stock volume has risen to an estimated 3.1 billion ft3. Livetree aboveground biomass is 112 million dry tons. In general, Iowa's forests are healthy. However, diseases, including white oak decline and Dutch elm disease, and the threat of invasion from exotic species such as emerald ash borer and nonnative plants are a concern when assessing the health of Iowa's forests.
