PHIPPSBURG — The first guided walk of the McDonald Marsh will occur at 9:30 a.m. Feb. 10 to celebrate the Phippsburg Land Trust’s acquisition and protection of 19.6 acres of sensitive habitat.

The marsh, off of Parker Head Road, has been preserved as part of land trust’s goal to protect waterways that feed into the sensitive Morse River. The land contains peat bogs, old-growth forests, ledges, and now a loop trail constructed by the land trust.

“It contains a significant wetland that feeds directly into Spirit Pond, that then feeds into the Morse River and out to the Atlantic,” said Dan Dowd, chairperson of the conservation committee for the land trust.

Small streams throughout the area, that often fill with snow melt, feed fresh water directly into the more brackish waters of Spirit Pond and eventually the Morse River. Phippsburg Land Trust has been working to protect all of the waterways feeding into the pond and river, which both represent sensitive intertidal habitat.

“The land trust has become very proactive around parcels that would allow for marsh migration,” said Dowd.

While many of the waterways in the marsh are small, they all eventually lead to the same place. Any pollution in those areas could have a domino effect on the entire waterway, which makes preserving them all the more important.

Brenda Cummings, president of the board of directors for the land trust, said preserving the estuary is important for Phippsburg as a whole.

“Everything that happens in the estuary affects us in Phippsburg, because we’re at the end of the road,” she said.

The inaugural walk will tour the loop-trail around the McDonald Marsh, along a series of rocky ridges and nearby old stone walls and graveyards. The walk starts at 9:30 a.m. at the preserve, from a parking lot located at 1043 Parker Head Rd.
