Have you ever wondered about the grasses growing along the trail? Join us for a moderate 2-mile hike at Ron Stewart Preserve Rabbit Mountain to learn about the warm-season grasses of the foothills. We’ll search for grasses while we discuss their vital role in the ecosystem and how they combat climate change. Look closely, and you might develop a new appreciation for our beautiful yet often overlooked grasses!
Registration for most programs begins on the 20th of the month before the event.
Registration required.
Registration is required through Discover Boulder County, Parks & Open Space’s volunteer and event registration system. If you’re new to the system, you’ll need to create an account. But it’s easy and we only use your contact information to communicate about events you register for. We will never sell or give your information to a third party.
