Types of old-growth forests

The old-growth forest types described here are based on DNR's classification of forest cover types. The cover type classification system is based on the most important tree species in the forest. The descriptions of old-growth forest cover types are general and old-growth characteristics vary considerably within a cover type. The native plant community classification documents this variation.

In Minnesota, the forest types shown on this page will develop old growth conditions if they escape catastrophic disturbance for a long time.

This section includes detailed description of the forest cover type, characteristics of the old-growth conditions, and a summary of special considerations for restoring and managing old-growth forests of these types.
