ZION NATIONAL PARK, Utah (AP) -- Helicopters next week will begin dropping herbicides and seeds across about 4,600 acres in Zion National Park.
The project is an effort to rehabilitate an area that burned in 2006. Park officials say the work will require temporary closure of some trails in the area of Kolob Terrace Road, Coal Pits Wash and Dalton Wash. There could also be delays along Kolob Terrace Road.
In 2006, the Kolob fire burned more than 10,000 acres in the park. Afterward, investigators said the area was threatened by nonnative cheatgrass, which creates a fire hazard. The herbicide is aimed at reducing cheatgrass in the area. The seeds are supposed to help re-establish native vegetation in the area.
The work could last for two weeks or longer, depending on the weather.
