Annual Report and Publications
Information on current conditions and trends in forest resources and the forest products industry in Wisconsin. These reports are produced annually by the Wisconsin Department of Natural Resources Division of Forestry, Utilization and Marketing Program and with the U.S.D.A. Forest Service.

- Average annual mortality of growing stock
- The average cubic foot volume of sound wood in growing-stock trees that died in one year. This statistic is an average for the years between inventories.
- Average annual net growth
- The annual change in cubic foot volume of sound wood in live trees through growth less volume losses resulting from natural causes. This statistic is an average for the years between inventories.
- Average annual removals
- The average net growing stock volume in growing stock trees removed annually for roundwood forest products. This statistic is an average for the years between inventories.
- Average weighted stumpage prices
- The weighted average is calculated by adding up the total value (volume multiplied by unit value) for each timber species and product combination of each timber sale in a given calendar year and then dividing by the total volume. The timber sale data analyzed was from both private land and public land timber sales conducted throughout the state. See Chapter NR 46 of the Wisconsin Administrative Code for more information.
- Forest type
- Classification of forest land based on the species forming a plurality of live tree stocking. The associated species for each forest type are based on the net volume of growing stock and all live biomass by species group.
- Gross growth
- Net growth plus volume losses due to mortality.
- Growing stock tree
- A live tree of commercial species that meets specified standards of size, quality and merchantability. Excludes rough, rotten and dead trees.
- Growing stock volume
- Net volume in cubic feet of growing stock trees 5 inches dbh. and over, from 1 foot above the ground to a minimum 4-inch top diameter outside bark of the central stem or to the point where the central stem breaks into limbs.
- Pole tree
- A live tree of commercial species at least 5 inches dbh. (diameter at 4.5 feet), but smaller than sawtimber size.
- Logs, bolts or other round sections (including chips from roundwood) cut from trees for industrial or consumer uses.
- A live tree 1 to 5 inches dbh (diameter at 4.5 feet).
- Sawtimber tree
- A live tree of commercial species containing at least a 12-foot saw log or two noncontiguous saw logs 8 feet or longer, and meeting regional specifications for freedom from defect. Softwoods must be at least 9 inches dbh. (diameter at 4.5 feet). Hardwoods must be at least 11 inches dbh.
- A live tree less than 1-inch dbh (diameter at 4.5 feet) that is expected to survive.
- Timber Mart North
- Reported prices resulting from a survey of timber buyers, sellers and their agents. Survey participants are asked to report on typical prices in the region during the specified period, to eliminate the variation that can result simply because of a limited number of observations. Published semi-annually by George Banzhaf & Company.
- Weighted average stumpage prices
- Calculated as the total value (volume multiplied by unit value) for each timber species and product combination of each timber sale.
