Speaker
Biography: Ashley Hall received her B.Sc. in Rangeland Ecology and
Management with a minor in Geographic Information Systems from the
University of Arizona (UA) in 2009 and a M.Sc. 2011. Her thesis focused
on researching nurse plant-protégé interactions between two species of
Bursage and Creosote, as well as creating a vegetation map of the Mohawk
Mountains and San Cristobal Valley on the Barry M. Goldwater Range.
After finishing her M.S., Ashley began working for UA Cooperative
Extension as a team member of the Cooperative Rangeland Monitoring
Program assisting the Bureau of Land Management in establishing a
vegetation monitoring protocol. Ashley worked for US Fish and Wildlife
Service as the Invasive Species Coordinator for Arizona Refuges. She
currently works for Gila County Cooperative Extension, focusing on
Rangeland Management and Animal Science.
Presentation
Description: Non-native species, like Yellow Bluestem (Bothriochloa
ischaemum) negatively affect the habitats they invade in many ways
including economically, environmentally, and/or ecologically. Yellow
Bluestem is a perennial grass introduced to the United States from
Europe and Asia in the early 1900s as a way to control erosion and as a
forage species. In the past several years, this species has become an
emerging invasive in Arizona. Yellow Bluestem has been shown to alter
soil function and biota, suppressing the growth of native vegetation..
It out-competes native species because it can grow much taller than most
native grasses, and creates a sod thick formation by reproducing
through underground stems. While this species was introduced in some
parts of the U.S. to provide additional forage for grazing species,
Yellow Bluestem is less palatable than natives and is not preferred by
cattle, equine, or wildlife. Eradication of this species may require
intense management efforts if a new population is not eliminated
quickly.
