Individual study: Growing-season prescribed fire and herbicide application, but not mowing, is effective in short-term control of the invasive grass Bothriochloa ischaemum on Blackland Prairie and Edwards Plateau, Texas, USA
Simmons M.T., Windhager S., Power P., Lott J., Lyons R.K. & Schwope C. (2007) Selective and non-selective control of invasive plants: the short-term effects of growing-season prescribed fire, herbicide, and mowing in two Texas prairies. Restoration Ecology, 15, 662-669
Native North American grasslands have been degraded by invasive plants. Their control (or eradication) is often hampered by shared characteristics with native plants. There is evidence that fire, herbicide or mowing management, can cause differential responses in native and invasive grassland species. Bothriochloa ischaemum (an introduced warm-season Eurasian grass) is increasing in southern and central North America. In this study, two Bothriochloa invaded grasslands at Blackland Prairie and Edwards Plateau (Texas, southern USA) were subject to various fire, herbicide and mowing regimes to assess effects on this grass and other plants.
The Blackland Prairie site (27 ha pasture) was dominated by B. ischaemum (39% cover) and native silver bluestem B. laguroides (19%). The Edwards Plateau site (10 ha pasture) was dominated by B. ischaemum (55% cover), with native Texas wintergrass Nassella leucotricha (15%) and meadow dropseed Sporobolus compositus (16%).
