Learn about Pollinators

June is Colorado Pollinator Month! Gardens can be designed to enhance the aesthetics of a site, but also to provide habitat that supports an array of wildlife including pollinators. Join Deryn Davidson of Boulder County Extension to learn about the various pollinator species you might see in your garden as you are out tending your flowers and veggies. We will also cover some design elements you can incorporate in your yard to attract them. Seating is limited. Please register at the Parks, Open Space, and Trails JoinUs volunteer portal.
