Rifle Ranch Riparian Restoration
A living lab for riparian restoration on Rifle Creek, turning a stretch of invasive-dominated streambank back into native habitat.
Why It Matters
Although riparian areas now cover just 3% of Colorado's landscape, they support nearly 90% of the state's wildlife. Below Rifle Gap Reservoir, altered stream flows and decades of adjacent agricultural use have caused Rifle Creek to cut a deeper, narrower channel, allowing invasive trees and grasses to overtake its banks. Restoring the riparian area, and the channel, brings numerous benefits.
It reconnects Rifle Creek with its floodplain, improves wildlife habitat, reduces erosion, filters water naturally and gives students and the community a living classroom where they can see stream restoration in action.
Impact Numbers
313 species documented at Rifle Ranch as of 2025, up from 160 in the 2018 baseline inventory
88.5% plant survival rate achieved by Phase II, despite severe drought
440+ volunteer hours contributed across Phase I and Phase II
Over 7,600 native trees, shrubs, forbs and grasses planted across three restoration phases (2019–2021)
Budget
Funded through a combination of federal cost-share programs (NRCS, USFWS Partners for Fish & Wildlife, CPW Habitat Partnership Program), grants, in-kind equipment donations, and volunteer labor.
Timeline
2016–2017: BioBlitz biodiversity surveys
2018: Baseline ecological inventory
2019–2021: Restoration Phases I, II, and III
2022–present: Long-term monitoring and maintenance
Connection to IWMP
Aligns with the IWMP's broader riparian restoration and invasives control priorities (Action WQR3), though Rifle Creek itself is not one of the specific tributaries named in that action's text.
Beneficiaries
Native wildlife, including 6 indicator bird species, 11 bat species, and breeding Northern Leopard Frogs (a Tier 1 Species of Greatest Conservation Need)
Pollinators, including 24 of Colorado's bumble bee species - roughly half of the 48 species found in North America (derived from the source's "half" statement, not a stated total)
Students and the community, through hands-on restoration and conservation learning
Downstream water quality and the working agricultural land the ranch shares its watershed with
Location
Rifle Ranch, a 122-acre property along Rifle Creek in the City of Rifle, Garfield County.
Status
Active. Major restoration phases complete; ongoing monitoring, maintenance, and continued species documentation underway. Low-tech processed-based restoration project under(LTPBR) Beaver Dam Analogs (BDAs) and rock dams installed in 2026.
