Feed your passion for the outdoors, and desire to give back to your local neighborhood park by helping plant a tree on Saturday, May 21 from 8-11 a.m. at Challenger Regional Park in Parker; Fairgrounds Regional Park in Castle Rock; or Highland Heritage Regional Park in Highlands Ranch.

Your desire to serve inspired this event as well as the launch of the County’s Parks Volunteer Program. Individuals and groups of all ages and abilities are invited to join the fun. Submit the volunteer application by May 11, 2022.   This event can qualify for community service.

All volunteers will receive an event t-shirt, water bottle, bag, sunscreen, and lip balm as well as a brief training on how to successfully plant a tree. Volunteers should dress for the weather, including sturdy shoes (no open-toed shoes), and are advised to bring gloves and hats.

Volunteers will assist Parks and Trails staff with the digging holes, prepping trees for planting, carrying supplies to planting site(s), mulching and watering.
