Opportunities From: Volunteers for Outdoor Colorado

Where You'll Be: 

DEN Open Space is a 585 acre park in Northeast Denver, situated in between the Rocky Mountain Arsenal Wildlife Refuge and DEN Airport. The park offers nature access and recreation opportunities for folks in the Montbello and Green Valley Ranch neighborhoods. The property is home to a lively prairie dog population, incredible cottonwood gallery, First Creek waterway and trail, and a beautiful but disturbed prairie ecosystem.

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You'll Do:

This project will take place on roughly the first 50 acres of the park north of the parking lot and 56th Avenue, along Buckley Road. This area has a high number of invasive plants, also called noxious weeds (Common Mullein, Scotch and Musk Thistle and has been a primary focus of the Denver Parks and Recreation Open Space team the past 2 seasons).

These plants are not native to Colorado and spread quickly, crowding out native plants. Volunteers will help remove young weed plants by hand pulling or digging them out. These young plants grow close to the ground in a circular shape, called a rosette, and are easiest to remove in the spring. Staff will show you how to identify the plants and demonstrate safe removal techniques. No experience is needed.

Why It Matters:

Removing these young plants prevents them from growing larger and producing seeds, which helps stop them from spreading. This gives native plants more space, water, and sunlight to grow. Healthier native plant communities support wildlife and improve the look and long-term health of the park for everyone who visits.

Eligibility Requirements:

Ages 10+

Youth under 16 must be accompanied by an adult aged 21 or older.

Project Difficulty:

This project is considered easy; please check our difficulty rating criteria here for more details. 

Physical activity may include some or all of the following: pulling or cutting vegetation, working on uneven or sloped terrain, bending and stooping for extended periods, carrying and hauling vegetation, possible exposure to allergens, potential for a long off-trail walk, and repetitive hand motions.

Access Factors:

Vehicle Access: No vehicle restrictions - 2WD accessible

Other Notes: The walk to the furthest point of the work area will be a 10-15 minute walk on a trail.

The goal of this project is to create an intentional outdoor experience that brings all people together. Curious about what we’re celebrating? Click here for more information on Pride Month.

Where You’ll Be: 

You’ll be volunteering at First Creek at the wildlife refuge. Volunteers for Outdoor Colorado first worked at this site in 2017 while helping build the First Creek Trail, marking VOC’s 1,000th stewardship project. VOC returned in 2024 for a native planting project. This project brings volunteers back to restore an underused area of the refuge and support improved access for nearby Montbello and Green Valley Ranch neighborhoods. The work area is also within view of the historic bald eagle nest that helped inspire the creation of the Refuge.

What You’ll Do: 

Volunteers will remove invasive plant species along First Creek, a tributary of the South Platte River. The goal is to support healthy riparian, wetland, and shrub habitat across about 1.5 acres. Target species for removal include curly dock, mullein, musk thistle, Canada thistle, and tumble mustard.

Why It Matters: 

This work improves wildlife habitat and enhances the overall visitor experience at the Refuge. It also supports nearby communities by improving access to outdoor space and contributing to local health and well-being.

Previous restoration efforts in this area have already helped reduce flooding during storms and allowed native cottonwood saplings to naturally establish, which would not have happened otherwise.

Eligibility Requirements: 

Ages 10+ 

Youth under 16 must be accompanied by an adult aged 21 or older.   

Project Difficulty: 

This project is considered easy; please check our difficulty rating criteria here for more details. 

Physical activity may include some or all of the following: pulling or cutting vegetation, working on uneven or sloped terrain, bending and stooping for extended periods, carrying and hauling vegetation, possible exposure to allergens, potential for a long off-trail walk, and repetitive hand motions.

Access Factors:  

Vehicle Access: 2WD vehicles can access the work site  

Other Notes: Cell service is spotty but usually available. Volunteers will park at the Visitor Center, and park staff will shuttle people to the project site (about a 15-minute drive) since it is off the usual Wildlife Scenic Drive; multiple van trips may be necessary for all volunteers.  There will be a port-a-potty on site.

Where you'll be: 

This project takes place in the Mount Evans Wilderness, located within Arapaho and Pike National Forests about 30 miles west of Denver. The wilderness spans more than 74,000 acres and is known for its high-elevation meadows, wide-open views, and wildlife such as bighorn sheep.

What you'll do:  

This weekday project is a great opportunity for volunteers ages 12 and up to spend time outdoors while supporting meadow restoration. Volunteers will hike approximately three quarters of a mile on the Captain Mountain Trail to reach the work site. Working in a group of about 20 people, volunteers will remove mature thistle blossoms, while staff follow up with a targeted chemical treatment that will be applied to the plants. If time allows, the group will also help identify musk thistle rosettes and Canada thistle to support ongoing management efforts.

Why it's important:  

Maintaining healthy native flora is essential for the local ecosystem, and, left unchecked, the invasive thistles will take over the area and out-compete native plants to create a monoculture. 

Eligibility Requirements:   Ages 12+ 

Youth under 16 must be accompanied by an adult 21 or older.  

Project Difficulty:

This project is considered moderate to easy in nature. Please check our difficulty rating criteria here for more details.

Physical Considerations: Pulling or cutting vegetation; walking and working on uneven, sloped, or rough terrain; bending and stooping for long periods; carrying and hauling vegetation.

Access Factors:  

Vehicle Accessibility: The last ~4 miles of the road (on Upper Bear Creek Rd) are not paved but accessible to all vehicles. All volunteers will meet at the lower parking lot and carpool (~2 mi) to the project site.

Other Notes: Restrooms available only at the main parking lot.

Where You'll Be:  

Valued for its remote feel and beauty, the James Peak Wilderness encompasses 14,000 acres to the southwest of Nederland, not far from the community of Rollinsville. It is home to high alpine lakes, wildflower meadows, and its namesake, James Peak, which sits at 13,294 feet. 

What You'll Do: 

Join us for a half-day project dedicated to preserving the natural beauty of the James Peak Wilderness. Volunteers ages 8 and up will spend the morning digging up invasive Oxeye daisies from the trailhead and surrounding areas. Led by experienced leaders Anna Zawisza (former VOC Staff) and Jim Jacobson (long-time volunteer), this project welcomes families and volunteers of all abilities to contribute to a multi-year effort spanning two decades. Your participation will make an immediate impact by enhancing the health of one of Colorado's popular Wilderness Areas. 

Why It Matters: 

Despite how cute they look, Oxeye daisies pose a significant threat as invasive weeds. For over two decades, VOC volunteers have removed thousands of flowers and seeds from the East Portal access point to the James Peak Wilderness. By joining this crucial effort, volunteers will help protect native plants and prevent the invasive weed from encroaching deeper into the Wilderness Area. 

Eligibility Requirements:  

Ages 8+

Where You’ll Be: 

Sand Creek Park is located in Aurora and co-managed by the City of Aurora and the Sand Creek Greenway Regional Partnership. Bicyclists, walkers, runners, picnickers, school groups, and community groups enjoy this 85-acre park and the Sand Creek that runs through it. The Greenway itself serves as one of the few green spaces that neighboring communities in Aurora, Commerce City, and NE Denver can easily access.

What You’ll Do: 

City of Aurora and Sand Creek Regional Greenway Partnership staff will teach you how to identify invasive Phragmites. After learning how to identify this plant, you'll spread out to clip and bag seed heads of the invasive grasses.

Phragmites grow along the water’s edge and into the water. If you have your own rubber boots or waders, you are encouraged to bring them to access the harder-to-reach plants. If not, you can stay on the shoreline and clip from there. 

Please bring your own lunch for the day! 

Why It Matters: 

Invasive plants out-compete native species for resources, thereby harming wildlife and the entire ecosystem. By carefully collecting the plants' seed heads, you will help control the further spread of this invasive species. Removing these grasses will allow for native plants to clean our water, prevent severe erosion, and provide enhanced wildlife habitat, all while maintaining access for local communities to enjoy this well-used green space.

Eligibility Requirements: 

Ages 12+   

Youth under 16 must be accompanied by an adult aged 21 or older.   

Project Difficulty: 

This project is considered easy, please check our difficulty rating criteria here for more details.

General physical considerations for participating on this project (Some or all may apply): Using loppers, walking along the water’s edge, and carrying bags or buckets full of plant material. There is significant sun exposure in this location.

Access Factors:
