The first full, annualized inventory of Wisconsin's forests was completed in 2004 after 6,478 forested plots were visited. There are more than 16.0 million acres of forest land in the Wisconsin, nearly half of the State's land area; 15.8 million acres meet the definition of timberland. The total area of both forest land and timberland continues an upward trend that began in the 1960s. Red maple, sugar maple, and quaking aspen are the most common trees with diameters at breast height greater than 5 inches; there are 298, 250, and 244 million trees of these species, respectively. Aspen is the most common forest type, followed by sugar maple/beech/yellow birch, and white oak/red oak/hickory. This report includes detailed information on forest attributes and health and on agents of change such as the introduction of nonnative plants, insects, and diseases and changing land-use patterns.

CalPro is an add-in program developed to work with Microsoft Excel to simulate the growth and management of uneven-aged mixed-conifer stands in California. Its built-in growth model was calibrated from 177 uneven-aged plots on industry and other private lands. Stands are described by the number of trees per acre in each of nineteen 2-inch diameter classes in two species groups, hardwoods and softwoods. CalPro allows managers to predict stand development by year and for many decades from a specific initial state. Users can choose cutting regimes by specifying the interval between harvests (cutting cycle) and a target distribution of trees remaining after harvest. A target distribution can be a reverse-J-shaped distribution or any other desired distribution. Diameter-limit cuts can also be simulated. Tabulated and graphic results show diameter distributions, basal area, volumes, income, net present value, and indices of stand diversity by species and size. This manual documents the program installation and activation, provides suggestions for working with Excel, and gives background information on CalPros growth model. It offers a comprehensive tutorial in the form of two practical examples that explain how to start the program, enter simulation data, execute a simulation, compare simulations, and plot summary statistics.
