Mowing Reduces Exotic Annual Grasses but Increases Exotic Forbs in a Semiarid Grassland
Restoration Ecology, 2014AbstractCheatgrass (Bromus tectorum) and other exotic winter‐active plants can be persistent invaders in native grasslands, growing earlier in the spring than native plants and pre‐empting soil resources. Effective management strategies are needed to reduce their abundance while encouraging the reestablishment of desirable native plants. In this 4‐year

Restoration of Exotic Annual Grass-Invaded Rangelands: Importance of Seed Mix Composition
Invasive Plant Science and Management, 2014AbstractRestoration of exotic annual grass-invaded rangelands is needed to improve ecosystem function and services. Increasing plant species richness is generally believed to increase resistance to invasion and increase desired vegetation. However, the effects of species richness and individual plant life forms in seed mixes used to restore rangelands ...

Stability of exotic annual grasses following restoration efforts in southern California coastal sage scrub [PDF]
Journal of Applied Ecology, 2008 Summary Restoration of semi‐arid shrub ecosystems often requires control of invasive grasses but the effects of these grass‐control treatments on native and exotic forbs have not been investigated adequately to assess long‐term stability. In southern California, coastal sage scrub (CSS) vegetation is one semi‐arid shrub community that has been invaded

Promoting Native Vegetation and Diversity in Exotic Annual Grass Infestations
Restoration Ecology, 2011Exotic plant invasions are especially problematic because reestablishment of native perennial vegetation is rarely successful. It may be more appropriate to treat exotic plant infestations that still have some remaining native vegetation. We evaluated this restoration strategy by measuring the effects of spring burning, fall burning, fall applied ...

Biological Invasions, 2004
Annual brome grasses, Bromus japonicus and B. tectorum, are common invaders of northern mixed-grass prairie, and have been shown to alter the structure and function of prairie ecosystems, including plant biomass production and litter decomposition. To build on previous findings, our objective was to model the impact of annual brome grasses on soil ...

Ecological control of exotic annuals in native C3 grass swards
Austral Ecology, 2018AbstractWhile the mechanisms behind the control of exotic annuals by C4 native grasses on soils of low fertility are well understood, it is not clear how C3 native grasses sometimes achieve similar levels of control. In earlier research (Cole I. A., et al., 2016a, Aust. Ecol. 41, 40; Cole I. A., et al., 2016b, Restor. Ecol.

Australian Journal of Botany, 2006
The species composition of temperate grasslands in the mid-north of South Australia has been radically altered from a system dominated by native perennial grasses to a system dominated by Mediterranean annual grasses. This study investigated the importance of chemical and physical soil characteristics, topographical features and climatic variables on ...

Mechanisms underlying the impacts of exotic annual grasses in a coastal California meadow
Biological Invasions, 2006Biological invasions can impact the abundance and diversity of native species, but the specific mechanisms remain poorly discerned. In California grasslands, invasion by European annual grasses has severely reduced the quality of habitat for native forb species.

Site-Specific Effects of Exotic Annual Grass Control Integrated with Revegetation
Ecological Restoration, 2015Invasion by exotic annual grass species such as downy brome and Japanese brome has been implicated in ecosystem degradation in much of the western United States and strategies to restore lands dominated by these species are needed. We evaluated integration of herbicide and revegetation to restore old-field and rangeland sites dominated by annual brome ...

Exotic annual grasses have been introduced into many semi-arid ecosystems worldwide, often to the detriment of native plant communities. The accumulation of litter from these grasses (i.e. residual dry biomass) has been demonstrated to negatively impact native plant communities and promote positive feedbacks to exotic grass persistence.
