Saguaro National Park resumes aerial spraying to control buffelgrass on Rincon Mountains
TUCSON, Ariz. (KOLD News 13) - Saguaro National Park park plans to resume aerial boom treatments to control buffelgrass on Wednesday, August 4 in the Rincon Mountain District.
According to a news release from the park, areas around the Tanque Verde Ridge, Manning Camp, Quilter and Arizona Trails may be closed between one and three days during active spraying.
Park officials said using herbicides on buffelgrass is only effective when grass is green after the monsoon rain.
A helicopter is used to treat buffelgrass in areas of the park that are inaccessible or dangerous to crews.
Park officials say they do not expect any boom spraying in the Tucson Mountain District this year.
Previously, aerial spray treatments have reduced the size and density of buffelgrass patches in the park by 75%, which allows the park to target areas that have not yet been treated, including a large area on the south side of the Rincon Mountains.
Closure notices will be posted here.
