Conservation/Management Issues
Potential threats:
- disturbance to birds;
- fire;
- overgrazing/overbrowsing;
- drought;
- excessive soil erosion/degradation.
Efforts to address threats:
Fire and livestock grazing on these grasslands have the potential of doing either harm or benefit to bird habitat. The U.S. Forest Service is inviting participation in grassland management at this site, by such parties as the Colorado Division of Wildlife and the Natural Resources Conservation Service, in an effort to promote the enhancement of the grasslands.
