Illinois forest lands comprise approximately how many acres?

• A. Over 4.5 million acres
• B. 3 million acres
• C. 6 million acres
• D. 1.5 million acres

Answer: (A)

Knowing how much land is considered forest land helps researchers and land managers track resources, planning needs, and conservation priorities. In Illinois, the area classified as forest land is a little over 4.5 million acres. That figure reflects land actually capable of growing and sustaining forest vegetation, and it’s used to gauge timber resources, habitat, and management programs.

So the best answer is the one describing over 4.5 million acres. The other options are smaller or larger than the typical Illinois forest-land estimate, which doesn’t match the actual inventory of forested area in the state.
