Since NSOLF's beginning in 1974 we have preserved roughly 850 acres that we own outright, which will remain preserved and undeveloped forever. We maintain this land with the help of volunteer land stewards, either keeping the space protected and unused or granting public access for walking, skiing, birding, and riding. It is our goal to increase the protected space in our town for plant and animal habitats as well as for human enjoyment.

Each preserve is overseen and monitored by a volunteer steward who visits the properties regularly and reports on its condition. We also fund the maintenance of these properties. That means keeping the invasive vines and brush out of our preserves, removing dead trees so that our trails remain safe for walkers and riders, and rebuilding culverts and stone walls that have crumbled over the years.

Dog Walking Policy

To ensure the well being of environmentally sensitive plants and animals, the ecology of water resources, as well as protecting the pristine and safe conditions for all visitors to our properties, dogs must be leashed and under the control of their owners at all times on all preserves.

We are grateful for your cooperation!
