The City of Boulder Open Space and Mountain Parks (OSMP) department is recruiting volunteers for a trail building project on National Trails Day, Saturday June 4, between 8 a.m. and 3 p.m.

This effort will assist in re-routing a section of Green Bear Trail. Volunteers will clear the trail corridor, haul slash and generally work toward establishing new tread. The re-route will move a portion of the trail out of the Bear Canyon riparian area. This, combined with previous trail projects, will help improve the entire length of the riparian area in Bear Canyon. Riparian areas provide essential habitat for a long list of plant and animal species and are some of the most biologically rich areas on the OSMP system.

A portion of the re-route will move the trail out of Preble’s Meadow Jumping Mouse habitat. This federally listed species requires riparian shrubland habitat, like those found in Bear Canyon, for feeding, breeding, and hibernation. The new trail alignment will also be more sustainable, resulting in a reduction of trail erosion that can both degrade water quality in the creek and impact native vegetation.

Volunteers should dress in layers and bring appropriate clothing for rain and full-sun exposure. Work gloves, sturdy boots or shoes, long pants, a long sleeved T-shirt, a water bottle, snacks, sunscreen and a hat are also necessary to participate. Tools and lunch will be provided. In addition, each volunteer will receive a custom-made project tee-shirt.

To pre-register for this event please visit www.osmp.org or call 303-413-7632. Due to the type of work and the location, registration is limited to 50 participants. These will be reserved on a first-come, first-served basis. Designated parking will be at New Vista High School parking lot at 700 20th St. Volunteers will be shuttled to the project site.
