We strive to make the Charles River and its parks a well-maintained network of natural urban places that invite and engage all in their use and stewardship.

2020 was deeply challenging in unprecedented ways, and reminded us of the critical role parks and greenspace play in our personal and public health. The Charles River and its parks need our stewardship now more than ever. Read about our 2020 accomplishments and where we’re headed in our year-end mailing and please consider making a gift!

Our October E-newsletter is out! Give it a read to learn about the latest CRC happenings and review past E-newsletters.

Starting April 10, 2021, and continuing through Sunday, November 28, 2021, MassDCR is closing Memorial Drive between the Eliot Bridge and Western Avenue to vehicles on Saturdays and Sundays. Visit Riverbend Park over your weekend to enjoy open space along the Charles! Learn more.

It’s official—our 2021 Earth Week Charles River Cleanup was a success! Over the course of six days, we worked with 20 groups, welcomed over 375 registered volunteers into the parks, and hosted four community cleanup sites in Cambridge, Boston, and Watertown. View pictures from the events!

Our work depends on equity, and we therefore cannot stay silent to racism and police brutality. Read our statement of solidarity with Black Lives Matter protestors in Boston and around the country.

Following “safer at home” guidance, all Charles River Conservancy staff are working from home until further notice. Please feel free to reach us via email and join us on InstagramTwitter, and Facebook where we’ll be bringing the beauty of the Charles River and parks to you!

Hell’s Half Acre Restoration

Hell’s Half Acre, a 7.5 acre section of “urban wild” along the Charles River in Cambridge, is an ecological and social asset to the surrounding community. However, the area is critically overwhelmed by invasive plants. Through a unique three-year project that uses best practices to remove invasives, the CRC is working to restore the area. Following this aggressive intervention, the CRC and Conservancy Volunteers will regularly maintain the revitalized Hell’s Half Acre. Learn more about Hell’s Half Acre Restoration.

Our Hell’s Half Acre restoration project addresses invasive plants, including phragmites, Japanese knotweed, and buckthorn.
