Lucas St. Clair poses on land proposed for a national park in Penobscot County, Maine. Mount Katahdin, the state’s highest peak, can be seen in the background as a rainstorm passes through Baxter State Park. St. Clair is managing a non-profit foundation set up to promote the creation of a park on about 70,000 acres owned by his mother, Burt’s Bees founder Roxanne Quimby.

PORTLAND — A key proponent of a national monument in Maine is challenging Republican Gov. Paul LePage to spend some time on the land before criticizing it.

The governor described the land as “cut over” on Monday and said it’ll take decades for the land to recover. He plans to testify against the monument created by former Democratic President Barack Obama at a House subcommittee hearing next week.

Lucas St. Clair, son of entrepreneur Roxanne Quimby, who acquired the land, said Tuesday that the governor should see Katahdin Waters and Waters National Monument before criticizing it. He called the 87,500 acres of donated forestland “an amazingly beautiful place.”

Republican President Donald Trump is expected to announce a review of monument designations on Wednesday. But it’s unclear if Trump can undo any monuments.
