Hours: Mon-Fri, 8:30 am - 4:30 pm



If you enjoy outdoor work and want to meet some nice people while helping the community, you will enjoy our projects. We meet once a month for a variety of conservation projects designed to support our beautiful natural heritage. Projects range from seed collecting to invasive weed control. No experience is necessary – we’ll show you what to do, and we’ll explain why it’s important. We’ll also provide gloves, goggles and hand tools (if needed), drinking water and snacks.

Dress to work outside

Wear layers of clothes that can get dirty. We strongly recommend blue jeans, sturdy boots, and three layers on top. We’ve learned that fleece jackets are just a magnet for sticky seeds and are best left in the car. We’ve also learned that if we’re cold we’re miserable, so we always recommend an extra layer of warmth – better to have it and not need it than the other way around.


We meet 9:00 a.m. to noon on the 2nd Saturday of each month and we alternate between two sites, unless otherwise noted*.
