Forest inventory expanding in 2023

We need help from private woodland owners! A new forest inventory program has begun, and woodland owners are eligible to participate.

Forest inventory provides data on the type, number, and size of trees in forests. This information is important for forest management decision-making. Lidar technology, combined with field plot-based inventory (PBI), is used to create precise and current forest inventory information on the forest landscape. Until now, PBI has been collected primarily on public lands. Expanding PBI to private woodlands will provide landowners and managers with valuable information needed to maintain Minnesota's forested ecosystem's beauty, health, and resilience.

Email DNR Forest Inventory for more information and check back here for sign up information coming soon.

Funding for this project was provided by the Minnesota Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources (LCCMR).
