Opportunities From: Volunteers for Outdoor Colorado

Why it's important: This training will go over essential skills for trail maintenance, trail construction, and trail drainage. When constructed and maintained properly, trails can go years without constant maintenance and be more effective at preventing erosion and keeping trail users safe. In this Friday workshop, you'll have the opportunity to learn from experts in the field, including OSI Instructors who have been building and maintaining trails for decades.

This training is designed to prepare volunteers for the Gilsonite Trail project on July 18-19.

What you'll learn: This skills training will explore several trail skills concepts such as trail construction/re-routes, trail maintenance, and trail drainage through hands on instruction and experience. Trainees will also get a chance to talk through some of the bridges and turnpikes that will be constructed during the project in the following days. Trainees will come away with an enhanced ability to assess trails for practical trail maintenance solutions and sustainable trail construction.

Where you'll be: This training will be in near Granby, Colorado. The exact location of the training and a detailed schedule will be provided two weeks out from the training date.

Essential Details: 

This training takes place on Friday, July 17. This training is free to attend.Please bring your own food and water to this training.

Where You’ll Be: 

The Gilsonite Trail is located in Grand County within the burn scar of the 2020 East Troublesome Fire. The project site is remote, about 50 minutes from downtown Granby. After the fire, many trail structures were damaged or destroyed, and flooding left sections of the trail swampy, muddy, and difficult to access.

Nearest Town: Granby, CO 80446

Exact location information will be shared with registered volunteers two weeks out from the project. 

What You’ll Do: 

Volunteers will be able to experience and help revitalize a trail post-fire. The Gilsonite Trail is a heavily used multi-use trail that provides an enjoyable experience for hikers, mountain bikers, and motorized users, keeping them off Stillwater Pass Road.  

In partnership with Headwaters Trails Alliance, volunteers will assist with a range of trail restoration tasks, including bridge and boardwalk replacement, turnpike construction, drainage work, and short reroutes. This work will help reopen sections of the trail that have been frequently closed since the 2020 fire. Some volunteers may also help move materials such as timber and rebar into the work area.

Adjacent to a fragile wetland and meadow, the work completed on this project will also keep users on the trail to prevent further trail widening, braiding, and wetland damage.  

Volunteers may need to assist with getting materials into the site (timber, rebar). 

VOC provides breakfast and lunch on Saturday and Sunday, and dinner on Saturday.

Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Why It Matters: 

This section of the trail runs alongside a fragile wetland and meadow. In its current condition, users often travel around muddy sections, which has led to trail widening and damage to the surrounding wetland. Replacing bridges, boardwalks, and turnpikes will help keep users on the designated trail and protect the nearby environment.

The Gilsonite Trail is also an important connector within the Stillwater Pass trail system. At nearly five miles long, it links the northern and southern portions of the system and provides a safer, more enjoyable single-track option than the nearby road. Volunteer work on this project will help restore a key connection in the trail system.

New to overnight projects with VOC? Learn more about what to expect here.

Where You’ll Be: 

This multi-year volunteer effort takes place in the foothills of the San Juan Mountains on public lands near South Fork and Del Norte in Colorado’s San Luis Valley. The valley includes high-elevation wetlands, shrublands, and forests that support a wide range of wildlife, including sandhill cranes, bald eagles, elk, mule deer, coyotes, and beaver. Moose and wolves have also been documented in the area.

Nearest Town: South Fork, CO 81154

The exact project location will be shared with registered volunteers two weeks before the project.

What You'll Do:

Across the western United States, barbed wire fences are widely used to manage livestock, but they can create dangerous barriers for migrating wildlife such as elk and deer. This multi-phase project aims to reduce those impacts and improve wildlife movement through key winter range areas.

This year’s volunteer project focuses on Phase 2: Fence Surveys and Prioritization.

Volunteers will work in teams to survey existing fence lines and identify sections that pose the greatest barriers to wildlife movement. Using the Survey123 mobile app, teams will map fence segments and record details such as fence type, condition, wire height, sharp corners, flagging, smooth or barbed top wires, and the height of the bottom wire.

Volunteers will also document signs of wildlife, including tracks, trails, or direct sightings of animals.

At the end of the workday, Wildlands Network’s Western Program Director will share more about the organization’s work and its conservation efforts in the San Luis Valley.

Project Phases Overview:

Phase 1: Pre-field planning and logistics: This will involve calculating fence segment lengths, identifying road access for each fence segment, parking areas, and other logistics for field operations.  Phase 2: Fence surveys and prioritization (this project) Phase 3: Camera monitoring before and after fencing adjustments: Once we have identified the fence segments to be modified or removed using volunteer surveys, we will deploy 45 remote trail cameras along select fence lines for a migration season before and after the treatment.Phase 4: Fence modification and removal projects in 2027: Two additional volunteer projects will be hosted in 2027 where we will complete the modification and removals to the identified 15 miles of fence. Phase 5: Data processing and analysis: All photographs collected from trail cameras will be processed to analyze the effectiveness of the project and compare outcomes with pre-work documentation.Food and Camping:

Enjoy breakfast and lunch on Saturday and Sunday, with dinner on Saturday. Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Why It Matters: 

This project is a collaboration with Wildlands Network, an international nonprofit working to reconnect and restore wildlife movement across North America.

Each year, large herds migrate between summer and winter ranges in the San Luis Valley. Fences can disrupt these essential movements, increasing injury and mortality for wildlife. Fence improvements such as raising bottom wires, lowering top wires, and replacing barbed wire with smooth wire allow animals to cross more safely while still meeting land management needs.

The data collected during this project will help prioritize future fence modifications and removals, directly supporting wildlife migration in the region.

Eligibility Requirements: 

Ages 16+ 

For overnight projects, all youth under 18 must be accompanied by an adult aged 21 or older. 

Project Difficulty: 

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

Where You’ll Be: 

Mount Democrat, at 14,148 feet and Colorado's 29th-highest peak, is part of the Mosquito Range, along with Mount Bross, Mount Cameron, and Mount Lincoln. The U.S. Forest Service recently acquired nearly 300 acres on Mt. Democrat, making the DeCaLiBron loop completely open to the public, for all to enjoy! Many underestimate this trail as an “easy” hike because of its high-elevation start, but it is rated a Class 2 climb. 

Nearest Town: Alma, CO 80424

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

What You’ll Do:  

Volunteers will assist with reconstructing portions of the trail above Kite Lake that have been widening and braiding at an excessive rate. Installing timber check steps will reduce soil loss and keep hikers on the trail. You'll work with our partners at Colorado Fourteeners Initiative (CFI) to install timber checks, delineate trails, and perform other maintenance tasks. The trailhead is at 12,000 ft of elevation (above tree line). Volunteers can expect to hike ~1.5 mi from the trailhead to the project site.

Where You’ll Be: 

Signature Bluffs Natural Area is a riparian and wetland natural area along the Cache la Poudre River with soft-surface trails, cottonwood stands, cattail marshes, and a pond where fishing is allowed with a valid Colorado license. The site is well known for wildlife and bird watching and connects directly with the Poudre River Trail for extended hiking or biking. The exact meeting location will be shared via email at least seven days prior to the project. 

What You’ll Do:  

Volunteers will help improve visitor access while protecting sensitive habitat at Signature Bluffs. Work will focus on closing and revegitating informal social trails around the lake to reduce habitat disturbance and support native vegetation recovery.

Volunteers will also improve the designated primitive trail by widening and defining it, creating a safer and more welcoming route to fishing access points. This project is a good fit for new volunteers and anyone interested in learning more about trail restoration.

Please bring your own lunch for the day.

Why It Matters: 

Informal trails can fragment habitat and impact wildlife and native plants. By restoring these areas and improving designated trails, this project helps protect sensitive ecosystems while guiding visitors to enjoy the landscape in a sustainable way. The work completed at Signature Bluffs supports long-term habitat health, safer recreation, and a better experience for everyone who uses the area. 

Eligibility Requirements:  

Ages 12+

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

Project Difficulty:

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 1.4 miles 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 easy to moderate in nature. Please check our difficulty rating criteria here for more details.

Where You’ll Be: 

Nestled in the Upper Yampa River Basin, about 1.5 hours northwest of Steamboat Springs, California Park is a high-elevation meadow known for its stunning views, vibrant wildflowers, and critical role in supporting the Upper Yampa River Basin and Colorado River Basin. This area is vital for water quality and watershed health, making it a key site for restoration efforts.   

The campsite is surrounded by beautiful, rolling, forested hills. While the site is remote, it offers a quiet setting that many people would not otherwise have a reason to visit.

You'll also likely travel through Steamboat Springs, so you have the chance to tack on a trip to nearby hot springs on the front or back end of the project!

What You’ll Do: 

In year two of this project, help restore this fragile meadow ecosystem by building erosion prevention structures, like Zeedyks and Zuni Bowls, primarily using rocks. These structures are proven, cost-effective methods to slow erosion and restore streams. Tasks will include hiking, moving large rocks, and digging to place them into position.

It’s challenging but rewarding work, you’ll leave with the satisfaction knowing that you've slowed erosion and helped revive a critical part of this watershed! This project will be completed in partnership with National Forest Foundation, Yampa Valley Sustainability Council, and the US Forest Service

Join us at Majestic View Nature Center (MVNC), a nonprofit that serves the Arvada community by offering a diverse array of public programming designed to foster connections with the natural world. From creative nature art sessions to engaging conservation presentations, MVNC ensures that individuals of all ages in the community can explore their connection with nature. You may be interested in visiting the nature center's exhibitions yourself!

Nearest Town: Arvada, CO

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

What You’ll Do:

Volunteers will get hands-on experience with stream and habitat restoration by helping build simple rock-and-wood structures (such as one-rock dams, Zuni bowls, and wicker weirs) that slow water flow, capture sediment, and support native plant recovery. Volunteers will move and place rocks, weave woody materials, and help stabilize the stream channel. No experience needed.

Please bring your own lunch for the day.

Why It Matters:

When streams erode, water moves through the landscape too quickly, washing soil away and leaving streambanks dry and unstable. The structures volunteers will build will slow water down, allowing sediment to settle and moisture to soak into the ground instead of rushing downstream.

Holding water in the landscape supports native plants, which stabilize streambanks and create habitat for birds, insects, amphibians, and other wildlife. Over time, this leads to healthier ecosystems, improved water quality, and greater resilience to drought and flooding.

Eligibility Requirements:

Ages 16+ 

Physical Difficulty:

This project includes tasks ranging from moderate to difficult. Please check our difficulty rating criteria here for more details.

General physical considerations for participating in this project (Some or all may apply): lifting and moving large rocks, digging holes, and placing rocks.

Access Factors:

Camping may be available for those who are interested in attending more than one day of the project. We will reach out 1 month before the project with more instructions on how to reserve a camping spot.

What You’ll Do:

Volunteers are needed to assist in monitoring the threatened butterfly subspecies, the Pawnee montane skipper. Monitoring will involve using binoculars to identify and record the number and gender of skipper butterflies, along with information on nearby host plants and trees. Please bring your own lunch for the day!

This butterfly species is only out and about when conditions are warm and dry. The project schedule is highly weather-dependent, but volunteers should plan to be on site for the full day.

Why It Matters:

The Pawnee montane skipper is a species with a narrow distribution that is endemic (native) to Colorado. Fire suppression, dam and reservoir development, and climate change are all threats to the persistence and recovery of this federally threatened species.

Eligibility Requirements:

Ages 18+

Project Difficulty:

This project is considered difficult and a great opportunity for volunteers looking for a challenge. Please check our difficulty rating criteria here for more details.

If a volunteer cannot commit to the full surveying time for the day, this could affect the integrity of the data, the safety of the group, and the project as a whole.

Physical Considerations: Volunteers can expect to hike off-trail through steep terrain for up to 5 miles round-trip. Elevation ranges from 6,000 ft to 8,000 ft. At this time of year, the weather is usually cool in the mornings but quickly warms to the high 80s or low 90s (though please check the weather in advance). This project is not for the faint of heart!

Access Factors:

Vehicle Access: No 4WD is required to reach the project area or sample sites; good tires are recommended to avoid flats on gravel roads. Beyond the initial meeting spot, we will aim to use agency vehicles whenever possible to minimize personal vehicle use.

Other Notes: Cell coverage in the area is minimal and varies by cell service provider.

Where You'll Be:

The Southern Plains Land Trust was founded in 1998 to protect and restore shortgrass prairie across the Southern Great Plains. Today, SPLT stewards more than 60,000 acres of protected land in southeast Colorado, where they focus on ecological restoration, reintroducing keystone species like black-tailed prairie dogs and American bison, and connecting local communities to the land through education and outreach.

This project takes place at the Purgatoire River Preserve, a newly protected 493-acre property in Bent County. Acquired by SPLT in January 2025, the Preserve is intended to protect the Boggsville National Historic Site, provide public access to the Purgatoire River, and create a new outdoor recreation resource for Las Animas and surrounding communities.

Nearest town: Las Animas

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

What You'll Do: 

Volunteers will help build a new natural surface trail on the Purgatoire River Preserve, just south of Las Animas. This trail segment will provide river access and connect to an existing trail at Boggsville.

Trail work will include construction of natural surface trail in a flat landscape.

The goal of this project is to complete a segment of trail that provides access to the Purgatoire River and connects to an existing trail in Boggsville. This is foundational work on a brand-new preserve, and volunteers will play a key role in creating the first public trail access at this site.

VOC provides breakfast and lunch on Saturday and Sunday, and dinner on Saturday.

Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday. 

Support This Project as a Crew Chef Helper! 

We provide full meals on our overnight projects to ensure volunteers are well-fed and ready for a day of volunteering, and we could use your help to make it happen! 

View this document to learn more about how to support and sign up.

Why it Matters:

Trail development at the Purgatoire River Preserve was guided by a community planning process in Las Animas that identified local recreation needs and priorities. This project represents the first step in creating a new recreational and educational opportunity in southeast Colorado. The trail design considers a wide range of users and mobility needs, helping ensure the Preserve is welcoming and accessible to the broader community from the start.

Where You’ll Be: 

This half-day project is a great opportunity for those looking for less physically demanding yet important and rewarding volunteer work. Boulder County Parks and Open Space staff will monitor seed development across various open space areas to determine the best collection sites. The exact project location will be shared with registered volunteers 4–7 days before the project.  

What You’ll Do: 

Help increase the availability of native seeds by hand-collecting a variety of species, including grasses, sedges, wildflowers, shrubs, and trees. This is a unique opportunity to expand your knowledge of native Colorado plants, as Boulder County Plant Ecologists will be on-site to guide you in identifying wildflowers and other native species throughout the project. 

Why It Matters: 

Using native seeds in restoration efforts is critical for helping the land recover after a disturbance. Unfortunately, native seeds are often unavailable commercially, prohibitively expensive, or not suited to the local ecosystem. 

Eligibility Requirements: 

Ages 8+ 

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 Considerations:  Hiking and bending over to collect seeds. 

Access Factors:  While the location is not yet determined, all locations should be 2WD accessible. Other Notes: Please note that the specific project location will be confirmed about one week before the event. The site selection depends on several factors, including seed development, weather conditions, and even wind! Our partners at Boulder County Parks & Open Space will actively scout potential sites, and we’ll share the location and logistics with registered volunteers as soon as the details are finalized.

Where You'll Be:

William Frederick Hayden Park sits atop Green Mountain, a prominent open space in the heart of Lakewood and one of the most well-loved urban parks on the west side of the Denver metro area. Originally donated by the Hayden family in 1972, the park now spans more than 2,400 acres, making it Lakewood’s second largest park.

Its extensive network of multi-use trails draws more than 250,000 visitors each year, offering an easy escape from the city for hikers, trail runners, mountain bikers, and families. From the 6,800-foot summit, visitors enjoy wide views of both downtown Denver to the east and the Front Range to the west, while the park also provides important habitat for wildlife including mule deer, elk, and great horned owls.

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

What You'll Do:

After a major trail reroute in 2018, some hikers have been cutting switchbacks along the middle section of the Rooney Valley Trail to avoid bike traffic and take a more direct route. We will be responding to these hikers recreating patters helping build rock steps that create a designated pedestrian bypass.

This allows hikers a more direct route while keeping the longer, gently graded switchbacks intact for wheeled trail users. Volunteers will assist with the construction of rock steps.

Please bring your own lunch for the day.

Why it Matters: 

The existing social trail follows a steep slope and is not sustainable. Continued use degrades wildlife habitat and spreads noxious weeds that threaten the native shortgrass prairie. Building this bypass helps protect sensitive habitat, reduces erosion, and supports the long-term goal of making every trail in William Frederick Hayden Park both sustainable and enjoyable.

Where You’ll Be: 

Mt. Sneffels, located in Ouray, CO, is accessible through Yankee Boy Basin. This basin is home to fields of wildflowers and wildlife and leads up to one of the most beautiful fourteeners in the state. Nestled in the San Juan Mountains, Mt. Sneffels receives about 5,000-7,000 visitors annually, which is relatively low but has some of the worst conditions of the five major ranges, according to a recent report card procured by Colorado Fourteeners Initiative. 

Nearest town: Ouray, CO 81432

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

What You’ll Do: 

At Mt. Sneffels, several large tundra beds are being undercut due to foot traffic. As soil erodes from beneath plant life, this delicate vegetation dies.

In partnership with Colorado Fourteeners Initiative, volunteers will help construct retaining structures and delineate the trail to ensure the continued health of this important alpine environment. Improvements such as installing tundra support walls and rock check steps will stabilize the footpath, allowing hikers to stay on the route and preventing widening of the existing trail. 

Enjoy breakfast and lunch on Saturday and Sunday, with dinner on Saturday. Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Why It Matters: 

Colorado’s 54 fourteeners (peaks over 14,000 feet in elevation) see over 300,000 hikers and climbers each year – all of whom are traveling through the alpine tundra ecosystem. This ecosystem thrives in an environment of high winds, short growing seasons, and cold winters, but is very easily damaged by foot traffic and erosion. Construction and maintenance of hiking trails on fourteeners prevent impacts to the sensitive plants and wildlife, and restoration projects repair areas that have already been damaged. 

Eligibility Requirements: 

Ages 18+ 

Project Difficulty: 

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

General physical considerations for participating in this project (Some or all may apply): long hike to worksite with significant elevation gain; carrying project tools and materials to worksite; digging, shoveling, moving soil and rocks; repetitive bending, lifting, and walking; working at elevation; working and hiking on steep or uneven terrain.  

You can expect to bend, squat, lift heavy objects, dig, reach, stretch, lean, rotate, and engage many muscle groups, all at a high elevation. This project is not for the faint of heart!    

The hike from the campsite to the worksite is up to 2 miles. Volunteers may be hauling project materials up the trail to the worksite (logs for structures). 

Access Factors:  

Vehicle Access: Moderate vehicle clearance and AWD is require to get to the camping location. 

Other Notes: This is a remote project. There is no cell service at the campsite or worksite.

Where You’ll Be: 

Button Rock Preserve is a 3,000-acre nature preserve outside of Lyons that protects the primary drinking water source for more than 110,000 Boulder County residents. The area supports passive recreation like hiking, rock climbing, and fishing along North St. Vrain Creek, Longmont Reservoir, and Ralph Price Reservoir. Volunteers will work in a scenic, high-use recreation area while helping care for an important community resource.

Nearest town: Lyons

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

What You’ll Do: 

Volunteers will support trail restoration work along the South Cove Trail at Button Rock Preserve.

The focus is on approximately 720 feet of trail that is severely undercut and collapsing into the reservoir, creating safety, access, and water quality concerns. Tasks may include defining trail tread, improving drainage for water to flow off the trail, building small reroutes, and assisting with retaining wall construction to stabilize eroding sections. This is a technical trail project in steep terrain and requires focused, hands-on work.

Why It Matters: 

South Cove Trail’s condition directly affects visitor safety, water quality, and access within a high-use recreation area. Restoring this trail segment will reduce erosion into the reservoir, improve safety for hikers, and support long-term stewardship and infrastructure resilience at Button Rock Preserve. 

Enjoy breakfast and lunch on Saturday and Sunday, with dinner on Saturday. Bring your own dinner on Friday night, and enough snacks for the weekend.

Why It Matters:  

The Parks Ranger District has recently been affected by two large wildfires and has since realized that most of the seeds from their seed stock are from the 70s or 80s. The seeds they do have are not the right species for the appropriate seed zones to meet the district's diversity objectives. Volunteer efforts to collect pine cones for this project will result in updated, relevant seed stock and seedlings ready to plant in the forest by 2029. 

Eligibility Requirements: 

Ages 16+ 

For overnight projects, all youth under 18 must be accompanied by an adult aged 21 or older.

For this project, we need a mix of A- and B-certified Chainsaw Sawyers. If you are certified, please include this in the Comments of your registration and send your certificate to the project manager. ALL SAWYERS MUST HOLD A CURRENT FIRST AID AND CPR CERTIFICATION IN ORDER TO OPERATE A SAW. Want to get certified? Visit our Training Calendar for upcoming training opportunities.

Christ the King Lutheran Church, a congregation of the Evangelical Lutheran Church in America (ELCA) has a proud history in the Harvey Park neighborhood of Southwest Denver dating back to its founding in 1956. The congregation was originally rooted in the rapid growth of the neighborhood in the late 1950's. They have partnered with Grow Local Colorado since 2018 and their plot is a wonderful example of how productive sheet mulch gardening can be. 

What You’ll Do: 

Through our long-standing partnership with Grow Local Colorado, volunteers ages 8+ will spend the morning harvesting a vegetable garden and prepping it for winter. Tasks will involve harvesting vegetables, weeding, and removing harvested plants to winterize the beds.  

Volunteers may also have the opportunity to hand deliver some of the fresh produce to local area food banks and community aid organizations. 

Why It Matters: 

The produce that VOC volunteers planted in the spring is now mature and ready to be donated to local organizations including food banks, homeless shelters, and families in need. By growing food locally, we reduce our carbon footprint by reducing the distance food must travel, minimizing water use, decreasing soil erosion, and helping develop a sustainable community. 

Eligibility Requirements: 

Ages 8+   

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

Where You'll Be:

Pence Park is a beautiful, quiet respite just thirty minutes from Denver. Pence Park's wide variety of trails has become a popular destination for hikers and bikers along the Front Range. Mountain bikers flock from miles around to ride from Lair O' the Bear to Pence Park, a scenic 13 miles. Pence Park's unique array of wildlife includes bald eagles, Mexican spotted owls, the Preble's jumping mouse, and the Townsend's big-eared bat.

What You'll Do:

Volunteers will help with much-needed trail maintenance at the park, just a short trip from the Denver metro area. Tasks may include clearing the trail corridor by trimming overgrown vegetation to keep paths open and safe, maintaining drainage by removing debris and improving water flow to prevent erosion, and repairing the tread to smooth and reinforce the trail surface for a safer and more durable path. This is a great opportunity for new volunteers and anyone interested in learning more about trail restoration while enjoying a beautiful outdoor setting.

Why It Matters:

Trail maintenance matters from an ecological and environmental standpoint because it ensures a safe and sustainable route for people to use, which keeps the surrounding habitat safe and minimizes the human impacts on flora and fauna, especially in high-use areas like Pence Park.

Eligibility Requirements: Ages 16+

Project Difficulty:

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

Physical Considerations:

Reaching the worksite requires a 1.1-mile hike with about 750 feet of elevation gain on a steep, rocky trail. Please be prepared for a moderate/strenuous hike before beginning the workday. You can expect to bend down, pick up objects, move rocks, carry tools, swing heavy tools, dig, and stretch.

Access Factors: 

Vehicle Access: No vehicle restrictions – 2WD accessible  Other Notes: Cell service may be spotty in this area. Port-a-potties will be available at the trailhead only; once on the trail, volunteers should follow Leave No Trace principles.

Where You’ll Be:  

You’ll be working at 1st Ave Pond, a quiet, behind the scenes natural area in the southernmost part of the City of Greeley. This site borders a small stretch of the South Platte River corridor and is currently closed to public access, allowing it to function as an important refuge for wildlife. With no formal trails or recreational use, the area provides undisturbed habitat for birds, small mammals, and other species that rely on intact riparian and wetland ecosystems.

What You’ll Do: 

Volunteers will help remove 10 to 15 foot Russian olive trees, an invasive species that threatens native vegetation and wildlife habitat along the South Platte River corridor. This project includes roles for both chainsaw certified volunteers and general volunteers. Chainsaw certified volunteers will cut Russian olive trees into manageable sections. Other volunteers will assist by moving cut material to a chipper staging area operated by the Forestry Division.

Only certified sawyers are permitted to operate chainsaws.

This project requires five B certified Chainsaw Sawyers. A certified Sawyers may participate under the supervision of B Sawyers.

If you are certified, please note this in the comments section during registration and email your certificate to the project manager.

All sawyers must hold a current First Aid and CPR certification in order to operate a chainsaw.

Interested in getting certified? Visit our Training Calendar to view upcoming training opportunities.

Why It Matters: 

Russian olive is designated as a List B species under the Colorado Noxious Weed Act, requiring active management to prevent its spread. These invasive trees displace native plants and wildlife and can consume up to 75 gallons of water per day, water that is critical for sustaining wetlands and the species that depend on them. Removing Russian olive at 1st Ave Pond helps restore native habitat, protect limited water resources, and strengthen the health of the South Platte River corridor. 

Eligibility Requirements: 

Ages 18+  

Project Difficulty: 

This project is considered difficult. Please check our difficulty rating criteria here for more details.  

Physical Considerations:

Expect physically demanding work, including moving heavy plant materials and working on uneven terrain. For volunteers not operating chainsaws, there may be lifting cut plant debris overhead at times, carrying logs, piling plant debris in one place, and using loppers. 

Access Factors:   

Vehicle Access: No vehicle restrictions – 2WD accessible

Where you'll be:

VOC's 5,000-square-foot Operations "Ops" Center in central Lakewood is home to a plethora of project equipment from tools to kitchen supplies. If you haven't been to the Ops Center before, this is a great opportunity to get a behind-the-scenes look at how VOC projects operate.

What you'll do:

Our annual OcTOOLberfest celebrates the successes of the season and prepares for the next one with volunteers and VOC staff alike. Each year, we enlist volunteers to clean, sharpen, paint, and repair tools, as well as to organize the VOC Operations Center. Spending a bit of time winterizing tools after months of hard use ensures they're in great shape for the start of next season!

Why it matters:

A well-cared-for tool is a safe tool! Dozens of projects each year take a toll on tools and equipment, and by the end of the season, they need some TLC. By helping us care for these tools and put them to bed for winter, you'll help VOC prepare for a safe and successful 2026 project season.

Eligibility Criteria:  Ages 14+

Project Difficulty:

The tasks available in this project vary from easy to moderate to difficult.

Access Factors: 

Vehicle Access: 2-minute walk from the parking lot to the Operations Center. Other Notes:  Restrooms on site.
