Researchers are using digital technology to improve forest management strategies.

Michigan State University scientists have employed a 3-D mapping technology called LIDAR—which stands for light detection and ranging—to make a digital model of a pine plantation.

Dave Carter is an assistant professor of Silviculture at MSU. He says LIDAR can survey areas faster than foresters.

“In terms of area, that person may only cover like 1% to 5% of the total stand, whereas a LIDAR measurement would conceivably cover like the whole stand aerially, and maybe accurately count and measure 90% to 95% of the trees in some cases.”

After LIDAR scans are uploaded, an AI model simulates different management strategies and finds the most effective ways to remove or apply treatments to trees, or even predict the effects of tree thinning.

“And we were just trying to demonstrate that that workflow was possible, where you could take that simulated thinning, pass it off to a model, have it project what the future yield would be as a result of your thinning, and then do that a number of times and figure out which method is best.”

Carter says AI can be faster and more precise than traditional methods of thinning, saving time and money. He says this technology could eventually be used by tree farmers as well as conservationists

Keweenaw County will become home to Michigan’s first public forest authority. 

The Nature Conservancy purchased 32,000 acres of forest land in Keweenaw County in 2022. Recently, county commissioners voted to create a local board to manage 20,000 acres of land in partnership with the conservancy. 

Robin Meneguzzo is the CEO of the Keweenaw Community Foundation. She says residents have four goals for forest management. “One is to protect the cultural and historical features of the land. One is to keep it a working, healthy, and intact forest, the third was to maintain government revenues, and the fourth was to maintain public access.” 

Newly expanded legislation opened the door for the forest authority by allowing small rural communities in Michigan to manage their own forest resources.

Meneguzzo says the project is uniting members of the community. “This is a really amazing example of a community coming together that has very different views on how land should be used or managed.” She says 29 different groups worked together for around 4 years to complete the project.

Meneguzzo says the forest covers around 15% of Keweenaw County’s footprint and is used for hunting, fishing, foraging, and hiking. 

Voters can choose forest authority board members in the November general election.
