Operation Save the Hemlocks of Koulas Farm
Hemlock trees in town have been ravaged by disease, and they are still some of the most beautiful trees we have. The old, large stand we used to have at Wright is now almost entirely gone. Hemlocks hold a special place in my heart. Even when they are struggling, they keep fighting to live, and […]
Chelmsford Sledding 101: What You Need to know
It’s a holiday, we have fresh snow, and the question shows up every single time. Where can I sled today in Chelmsford, and what hill is best for my crew. One thing I love about COSS is we do not have blinders on. Open space is open space no matter who owns it. Town land, […]
The Gathering Rocks: A new Project Approved for Koulas
The Gathering Rocks is one of those little Koulas Farm mysteries that makes you stop and say, “Ok, someone did this on purpose.” Right at the junction of several trails, there is a man-made circle of rocks. It is not a natural boulder ring, and it does not match the random scatter you see everywhere […]
Massive Stone Removal Project Under Way At Koulas

War on Invasives declared at Koulas Farm
Invasives and rocks. Chelmsford might hold the world record for both. When people hear us say we have bittersweet vines 6 to 8 inches thick, they do not believe it. They think we are pulling their leg. I wish that was not true, but it is. Our open spaces have a serious invasive problem. COSS […]
Playing Games in the Woods (geocaching)
Geocaches are one of those things that run hot and cold. Right now we are somewhere in the middle, and that is actually a great time to jump in. In the old days, you had to buy a handheld GPS for about $100. Now your phone can do it. So what is geocaching It is […]

Diversity is Important. Native Plants are the Best
Whatever is decided for the Koulas Farm entrance garden, the Town will be the one to decide, as it should be. There are volunteers ready to help when the time comes. The more I look at native plantings, the more I like the look, and they are better for bees and other pollinators. Keeping the […]
