Seasonal Comparison On The Effectiveness Of Control Methods For Microstegium Vimineum In The North Carolina Piedmont, Casey Beam Dec 2022

Seasonal Comparison On The Effectiveness Of Control Methods For Microstegium Vimineum In The North Carolina Piedmont, Casey Beam

Theses and Dissertations

Microstegium vimineum, or Japanese stilt grass, is an invasive species that readily outcompetes native vegetation and is of poor forage quality for wildlife. This species is widespread throughout the southeastern United States, including North Carolina. Much of this region is privately owned and there is a gap in the literature providing succinct information about the best methods of treatment, timing of treatment, and effects of treatment on native herbaceous plants in this region. In two parts, this study seeks to address this gap by employing treatments that are easily accessible to landowners at different times during the growing season and …


Effects Of Post-Fire Disturbance Responses Of Microstegium Vimineum On Native Hardwood Seedling Growth And Survival, Zachary A. Chandler Dec 2022

Effects Of Post-Fire Disturbance Responses Of Microstegium Vimineum On Native Hardwood Seedling Growth And Survival, Zachary A. Chandler

Theses and Dissertations

Invasions by alien understory plant species have gradually become a worldwide challenge in maintaining forest biodiversity and ecosystem productivity. Notably, Microstegium vimineum, a C4 grass native to Japan, has increased dominance in mixed deciduous hardwood forests of the southeastern United States, largely due to its shade tolerance and ability to spread through rhizomes. Microstegium vimineum also proliferates after prescribed fire, a common management tool used in the region to restore forests to desired conditions, and may compete with hardwood seedlings, hindering restoration efforts. Using two upland deciduous hardwood forest research sites in Marshall and Tate Counties, Mississippi, this study …
