Restoring a Lost Garden at Koulas Farm
Koulas Farm has had a few buildings on the site at 185 Pine Hill Road. When we worked on clearing along Pine Hill Road last winter, we pulled out a lot of dead brush and junk and cleaned up the area around a large boulder that feels like a perfect point of interest...
Tell Me About Barlett Park
Bartlett Park is one of those places that plenty of people use, but not everyone really knows. Most of us drive by it a hundred times a year. It is right in the center of town near the library, surrounded by busy roads and downtown life. But the second you step onto...
Tell Me About Heart Pond
As some know, we are adding information items for each site around town. The information presented is fair and balanced and gives a snapshot of what you will find. Here is the one for Heart that will go live today. Give it a read and let me know if I missed something...

COSS supports individuals, community groups, and organizations through outdoor projects, educational efforts, and service initiatives. Our work includes assisting Scouts and nonprofits, helping local farmers, maintaining trails and gardens, building accessible infrastructure, and repurposing donated tools for public use.
Scouting
The Chelmsford Open Space Stewardship actively works with Scouting America. Since 2005 we have helped Scouts with over 20 Eagle projects and numerous camp-outs and educational nature walks.
Land Trusts and Conservation
The Chelmsford Open Space Stewardship works with Land Trusts and Conservation groups in Chelmsford and surrounding towns to preserve, improve, and protect the Open Spaces.
Local Farming
The Chelmsford Open Space Stewardship has supported local farmers and community growers helping to set up full hoop style green houses and individual growers' raised garden beds.
Wildlife Preservation
As stewards of open spaces, we aim to protect many locations for use by humans and wildlife - both flora and fauna. We aim to preserve native plants (especially pollinators) and make spaces that will attract wildlife. We support initiatives like the Newhouse Wildlife Rescue and provide native pollinator plants to those who would like to use them.

Every time you think of a city, you have to think green, green, green. Every time you see concrete jungle, you must find open spaces. And when you find open spaces, make it so people can get to them.
