ROCKLAND, Maine — An environmental activist has been nominated by the Green Independent Party to be its nominee for the vacant Rockland-area House seat.

Ron Huber of Rockland was picked by the Greens at a caucus Saturday in Rockland.

Huber is executive director of Friends of Penobscot Bay. He has been involved in numerous environmental efforts to clean up the bay. Over the years, he has been involved in many Searsport matters, including the recent fight over the proposed liquid propane gas tank and the battle over the future of Sears Island.

Huber will vie for the House District 93 seat — which represents Rockland and Owls Head — along with Democrat Anne “Pinny” Beebe-Center of Rockland, Republican James Kalloch of Rockland and unenrolled candidate Libertarian activist Shawn Levasseur.

The special election to fill the vacancy created by the resignation last month of Democratic Rep. Elizabeth Dickerson of Rockland. Dickerson moved to Colorado less than a month after being sworn into office for a second term.

The election will be held Tuesday, March 10. Polls will be open 8 a.m. to 8 p.m. at the Rockland recreation building and at the Owls Head town office.
