For Immediate Release
Ron Terry 435-772-0160
Starting October 25, 2007, ZionNational Park will begin the aerial application of herbicide to the area burned in the Dakota Hill Complex Fire. The herbicide will be applied to 3,161 acres located in the vicinity of the West Rim Trail and in the northeast corner of the park, near Dakota Hill. The herbicide is intended to minimize the invasion of cheatgrass and other highly flammable exotic grasses. The treatment will allow native plant species to grow and re-colonize the burned area without competition from exotic grasses. Because of the remote and rough terrain in the burn area, helicopter application of the herbicide will be used. The project is expected to be completed by November 10, 2007.
During a portion of the project, from the night of October 28 through November 2, HeapsCanyon, UpperImlayCanyon, and the West Rim Trail from Potato Hollow to the bridge below Little Siberia will be closed. Backcountry visitors in other nearby areas should be aware that low flying helicopters will be present and will be heard.
Check at the visitor center or on the park website www.nps.gov/zion for the most current information on the closures.
