On a warm August morning, a group of volunteers gathers in the high desert about 20 miles outside of Gunnison, Colorado. Here, surrounded by sagebrush and armed with branches and stones, they are ready to help restore a critical wildlife habitat.
Volunteers are here to work on a wet meadow restoration project. A wet meadow is a riparian area in the arid sagebrush landscape.
“I always joke around that I should’ve majored in basket weaving instead of wildlife management because that’s definitely a skill we’re going to be using today,” said Nathan Seward, a conservation biologist with Colorado Parks and Wildlife.
Volunteers like Payten Maness weave willow branches into protective barriers. The team will also build with sagebrush and stones collected nearby.
“I think it’s really cool how we are doing it here,” Maness said. “It’s super low-tech, which means that basically anyone can come in and do it. You don’t need a lot of training.”
The team uses locally-sourced wood posts and rocks to build simple structures and artificial beaver dams along sections of Munson Creek. Those structures slow the water down and spread it out.
Max Sawyer is a master's student in Environmental Management at Western Colorado University. He’s working on wet meadow and riparian habitat restoration in the Gunnison Basin as part of his coursework. He said a narrow stream creates a very small strip of habitat going through the valley bottom.
“The goal of this restoration project is to get this stream to rewet more of the valley bottom again,” Sawyer said. “Spread it out, move it to the edges of our meadow, reduce some of our upland species that have come down, some of the sagebrush, get it out of the valley bottom and get more of those riparian species in here.”
Wet meadows and riparian areas in sagebrush country only account for about 2% of the landscape. Trouble for these systems started when white settlers moved West. Instead of taking their wagons through the sagebrush where it was rocky and rough, they followed the edges of the meadows.
Seward said the wagon wheels created trenches that were reinforced by livestock trailing between water sources, and eventually off-road vehicles using the same paths. These trenches caused water to pool.
“When water gets captured in those trails it speeds up and becomes more erosive and it starts to downcut,” he said. “It starts actually washing away the topsoil and working its way until it finally hits the bedrock.”
Sawyer said these impacts are being sped up by climate change.
“We are trying to prevent these systems from disappearing entirely from our landscape,” he said.
Wet meadows provide critical habitat for deer, elk, migratory birds, pollinators, livestock and the federally threatened Gunnison sage grouse.
Colorado Parks and Wildlife estimates there about 3,500 Gunnison sage grouse left, with a majority of the population living in the Gunnison Basin. In 2015, there were around 5,000.
The species suffers habitat loss due to human-driven growth and development. The birds need large swaths of healthy sagebrush habitat to thrive. Climate change also threatens what’s left of the species habitat. Wet meadows provide sage grouse with important brood-rearing habitat to raise chicks.
The Wet Meadows Restoration Resilience Building Project is a local effort to restore habitat for the threatened Gunnison sage grouse. It’s a collaboration by government agencies, nonprofits, private landowners and the public.
Wet meadows also act as natural sponges, holding water in the soil and slowly releasing it over time. Seward said the restoration work helps build resiliency into the ecosystem. That will only get more important as climate projections indicate the area will get warmer and drier.
“Everyone knows that water in the West is life,” he said. “All life needs water, so by holding more water here in the Gunnison Basin longer and putting it to good beneficial use for wildlife, for our agricultural industries, like ranching as well — really everyone benefits from this kind of work.”
Project organizers said the restoration is working in the Gunnison Basin. Overall, they’ve seen wetland vegetation double in treated areas since the program started in 2012.
This is just one of dozens of watershed restoration projects in Colorado and states across the West. Wet meadow restoration projects to benefit the Gunnison sage grouse are also happening in San Miguel, Montrose, Mesa and Delta counties.
And across the West, there are other watershed restoration projects in states like Utah, Nevada, California, Montana, Idaho, Oregon and Washington.
