Partner Spotlight: Grand Staircase Escalante Partners
Long-term, science-led restoration is helping the Escalante River recover its natural flow, habitat and resilience
by Brian Riepe
Southern Utah’s Escalante River and its quiet tributaries wind through sandstone canyons and cottonwood groves that hold far more life than the desert surroundings might suggest. These green corridors are essential habitat for native fish, migratory songbirds, pollinators and countless desert mammals. But for decades, one invasive tree—Russian olive—silently transformed the watershed. Tight thickets crowded out native vegetation, narrowed channels and altered the river’s natural flow.
For more than 16 years, Grand Staircase Escalante Partners has been leading a restoration effort ambitious in both scale and vision. Working across 1.9 million acres of rugged terrain, the team collaborates with landowners, federal agencies, youth corps crews, scientists and local communities to clear invasive trees, nurture native plant communities and track how the river responds over time. What has emerged is one of the most successful riparian restoration efforts in the Southwest; a model of long-term commitment and science-driven stewardship.
A watershed beginning to breathe again
In partnership with the Forever Our Rivers Foundation and other partners, GSEP treated more than 1,400 acres of Russian olive in 2024. While Phase I removal across the watershed was completed in 2019, young regrowth still appears, and retreatment is essential. Each acre cleared allows sunlight to reach the soil again. Cottonwood and willow seedlings can reestablish. Floodplains can reconnect to the river. Birds return to nest in healthier habitat. Threatened fish regain pools and riffles shaped by a more natural flow regime.
These changes are subtle in the moment but profound across years. To understand them, GSEP conducts extensive monitoring; work as physically demanding as it is scientifically valuable. In September, staff and partners trekked into backcountry reaches of the Escalante to survey 19 long-term vegetation plots, documenting plant composition and canopy structure. Their findings are helping reveal how native communities recover after invasive removal and which areas may need additional attention.
Science shaping restoration and the future
One of the most remarkable aspects of this project is the scientific insight emerging from collaborative research. Using historical aerial imagery, retired U.S. Geological Survey scientist Mike Scott continues to measure how channel width has changed over time before Russian olive invasion, after invasion and after years of treatment. Early results show that when dense invasive stands take hold, rivers narrow unnaturally. But as they are removed, channels begin to widen again and regain their meandering shape.
Graduate researchers are also examining how warming temperatures may influence the spread of Russian olive and how restored sites evolve across decades. Their work adds context to the on-the-ground data GSEP collects, providing a more complete picture of how climate, vegetation and hydrology interact desert rivers. These layers of study directly guide future restoration work and help partners understand where, and how the watershed is most resilient.
Partnerships grounded in place
GSEP’s success is a reflection of deep, long-standing partnerships. As the official friends group of Grand Staircase-Escalante National Monument, they work closely with the Bureau of Land Management to secure long-term permission for restoration and monitoring. Through the Escalante River Watershed Partnership, they collaborate with agencies, youth corps crews and fellow nonprofits dedicated to riparian health.
This collective effort reflects a shared belief: a healthy river is the beating heart of a healthy desert. When its channels widen, its floodplains breathe and its native species rebound, entire ecosystems benefit.
Why this work matters
The Escalante River does not reveal its transformations overnight. Change emerges slowly: sprouts of willow emerge, a more open floodplain invites the return of a migrating warbler, a population of speckled dace minnow reappear in shallow riffle. But over years, these small shifts add up to resilience. They show that with patient, coordinated and science-led care, even highly altered desert rivers can recover.
In partnership with Forever Our Rivers, Grand Staircase Escalante Partners continues to demonstrate what steady stewardship looks like: hands in the field, data in hand, goals shared across communities and unwavering commitment to a river that shapes one of the most iconic landscapes in the American Southwest.
Their work strengthens not only the places we cherish but also our understanding of how to care for rivers facing similar challenges across the region.
