Introducing the Northern Research Station

The North Central Research Station and the Northeastern Research Station have joined to form the Northern Research Station. Our 20-state region spans the Midwest from Minnesota to Missouri and the Northeast from Maine to Maryland.

Forest Profile for Indiana

Indiana has 4.3 million acres of timberland, which:

Bulleted item Covers 19 percent of the state area
Bulleted item Ranks 35th out of 50 states
Bulleted item Comprises 14 percent public ownership

Eighty-five different species of trees grow on Indiana's forest lands.
Maple-beech-birch is the most common forest type, closely followed by oak-hickory.

Growing stock volume in Indiana increased 33 percent between 1986 and 1998.

70 percent of Indiana's timberland was forested by sawtimber-stands. This figure is likely to continue to increase.
Growth exceeded harvest by a ratio of 2. to 1.

Private individuals own 85 percent of Indiana's timberland.
That private ownership is spread among 141,300 individuals.
The Hoosier National Forest contains 4 percent of the timberland; the state and other federal agencies own 11 percent.

The forest products industry contributes $2.55 billion annually to Indiana's economy.

Bulleted item2 stave mills

Although the forested area of Indiana is comparatively low, forest acres can be highly productive due to good site quality. Among states in the North Central region, Indiana has the highest timber volume per acre of timberland. Indiana also has the largest number of veneer mills for processing high value hardwoods.

Issues and Opportunities for Indiana Forests
With the increasing levels of average stocking on Indiana's forests, oak regeneration may become a problem where scientific forest management is not implemented. Since oak is Indiana's most economically important species, this could have long-term implications

Urban sprawl is contributing to the increasing fragmentation of Indiana's forestland. Implementing sound forest management on small tracts of land is difficult due to economies of scale. This may lead to increased problems with forest pests and disease, and a successional shift to shade-tolerate species.

Our Contributions
Every year, the North Central Research Station's field crews inventory sample plots on public and private lands in Indiana. That information feeds our annual report of forest conditions and timber product outputs. Additional information about Indiana's forests is available in the following publications.

North Central Partners in Indiana
In addition to forest inventory and analysis, we engage in research with an array of partners in Indiana. A sample of those partners is listed below.
