There's new federal funding for the fight against invasive buffelgrass in the Tucson Mountains. Also: Hungry sheep and goats could soon join the war against buffelgrass on 'A' Mountain.
Henry Brean Southern Arizona’s weed warriors just got more ammunition for their fight against buffelgrass in the Tucson Mountains.
Digging is prohibited on the hill because of the large number of cultural sites there, so contract crews will fan out to spray the weeds with the popular herbicide glyphosate. Buffelgrass is native to Africa and Asia, where it populates grasslands that burn frequently as part of the natural ecological cycle.
By some estimates, buffelgrass now covers as much as 5,000 acres in the Tucson area alone. About 2,000 acres of that can be found in Saguaro National Park, where aerial spraying and volunteer weed-pullers have at least kept the problem from getting worse. The slopes of Tumamoc Hill are covered with about 200 acres of the stuff. Colodner said it will take about 10 years of “intensive treatment” to bring the weeds under control there.
“It's hard sometimes to convince people that grass is a threat — a threat fire, a threat to biodiversity, a threat to species and a threat to the landscape that we all love and are familiar with and cherish,” Grijalva said. “It is a threat, and we need to approach it as a threat.”Sheep terrain Hungry livestock could soon join the war against buffelgrass on"A" Mountain.
