Finding the Koula’s Vernal Pool
ou could hear them before you saw anything. That’s usually how it starts this time of year. John Ray was out at Koulas talking about peepers, and if you’ve ever been there on the right night, you know exactly what he means. It’s not one or two frogs. It’s a wall of...
The Day Heart Pond Drained
Yesterday was April 1st, a day for tricks and a little fun. I didn’t do anything this year, but it got me thinking about some of the ones I’ve pulled over the years. There have been a few, but one still stands out as a classic. This goes back maybe 10 years at Heart...

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.
