The Dolores River Restoration Partnership
The Dolores River Restoration Partnership (DRRP) was founded in 2009, and has since worked to restore nearly 170 miles of the Dolores River riparian corridor following the removal of invasive tamarisk. The partnership has successfully removed about 70% of the tamarisk initially mapped and has subsequently focused their collective efforts on monitoring and maintaining past work, while strategically working on tamarisk removal in hard-to-reach areas.
As part of the monitoring program, invasive species of concern are mapped, and that data is given to crews who will go into the field and remove or treat the species as determined by DRRP coordinators and the Bureau of Land Management.
Active revegetation of native trees, shrubs, forbs, and grasses is also part of restoration. Active revegetation often is conducted in areas with ideal soil, locations that would benefit from greater plant diversity, and areas where there is minimal cattle grazing as to prevent predation. These sites can take several years to reach a level of restoration and ongoing stewardship is critical to the long-term health of the Dolores River corridor.
