Control Of Three Invasive Annual Grasses In Utah Using Herbicides Including Indaziflam, Hailey L. Buell Dec 2021

Control Of Three Invasive Annual Grasses In Utah Using Herbicides Including Indaziflam, Hailey L. Buell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Invasive grasses pose a threat to rangeland ecosystems in Utah. Three grasses in particular: downy brome, medusahead, and ventenata can push out native plants and prevent other vegetation from germinating. These grasses can also degrade grazing lands for cattle and act as kindling for wildfires. The use of herbicides is the most common way to rid a site of invasive plants. Herbicides that prevent germination for many years work well to keep annual grasses at bay while not harming the many long-living native plants that are already growing.

A study was designed on a site infested with downy brome to …


Transplanting Mature Mountain Big Sagebrush Plants Yields High First-Year Survival In Dryland Pasture Restoration, Elizabeth C. Bailey Aug 2021

Transplanting Mature Mountain Big Sagebrush Plants Yields High First-Year Survival In Dryland Pasture Restoration, Elizabeth C. Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Approximately 10-20% of global dryland ecosystems are severely degraded, an amount that is expected to increase, threatening the environment and ecosystem services that 38% of the global population relies upon. Human activities such as agriculture, livestock grazing, mining and urban development have contributed to the degradation and loss of rangelands worldwide. A need for reestablishing sagebrush in disturbed landscapes across the Western United States, including dryland pastures, has been identified but traditional, primarily seeding-based, restoration methods have largely been unsuccessful. To improve restoration outcomes, there has been increased interest in the planting of containerized greenhouse “tubelings”, but transplanting of mature …
