Pollinator-friendly flora in rangelands following control of cheatgrass (<i>Bromus tectorum</i>): a case study

Abstract Invasive winter annual grasses, such as cheatgrass ( Bromus tectorum L.) are considered serious threats to regional biodiversity. Pollinator populations that depend on the native flora likely be negatively impacted these species may displaced by invasive grass species. Colonization is also predicted increase risk of wildfires, dead plant parts provide fuel in already dry and arid regions western United States. Biocontrol, grazing, prescribed burning, or use broad-spectrum nonselective herbicides have been suggested possible means control B. . Efficient facilitate regrowth could turn support other ecosystem functions. Reporting our findings a case study, we describe here results application preemergent herbicide, indaziflam, limits germination seeds. Herbicide was applied study locations during months December 2016, January 2017, February 2017. The data reported diversity flowering plants were collected between May through September 2018. Herbicide-treated plots showed an abundance compared untreated within two seasons after implemented, suggesting effective reduction population help growth forbs. Further studies necessary understand mechanisms reestablishment species, long-term consequences reducing grasses document any residual effects herbicide ground-nesting pollinators.
