(Lander, Wyo.) – Tomorrow spraying for cheatgrass control will be done in Sinks Canyon in areas affected by the Fairfield Fire; the spraying will cause closures in some areas of the canyon.
Bureau of Land Management Natural Resource Specialist-Fire Tim Kramer said the spraying will likely begin between mid-morning and noon, weather dependent. The spraying will be done via helicopter.
Access to the main climbing wall in the canyon will closed for the spraying, Kramer said, calling it the closure area that would affect the most people.
The road through the canyon will not be closed, and spraying will be limited to BLM and Wyoming State Park land.
Fremont County Weed & Pest’s Nancy Pieropan said cheatgrass germinates in the fall, and the goal of the spraying will be to minimize spread of the invasive specie.
“Cheatgrass tends to occur where there is low perennial grass cover, recent fire, soil disturbance, or shallow soils,” states information from the University of Wyoming Cooperative Extension Service. It later states, “Late summer fires reduce litter that encourages cheatgrass growth.”
The Fairfield Fire burned more than 1,300 acres in July.
Kramer did not expect spraying or closures to extend beyond Tuesday.
