The American Midland Naturalist, 2003
Annual brome grasses, Bromus japonicus and B. tectorum, are common exotic plants in the northern mixed grass prairies of North America. As annuals, the bromes die following seed set in late spring, creating a functional difference between them and native perennial grasses because perennials continue to maintain live shoots into the summer and root ...

Abstract The annual brome grasses, Bromus japonicus and B. tectorum, are common invaders of the Northern Great Plains. Our objective was to determine if these exotic plants were positively or negatively associated with particular plant species or functional types in a prairie/pine ecotone at Wind Cave National Park, South Dakota.

Plant Ecology, 2018
Climate change will not only alter mean conditions, but increase the frequency and intensity of extreme events such as severe droughts. Yet the consequences of extreme drought for plant demography are poorly understood. We compared phenology, demographic rates and effects of competition with exotic grasses for the California annual forb Phacelia ...

Control of Exotic Annual Grasses to Restore Native Forbs in Abandoned Agricultural Land
Restoration Ecology, 2011Exotic annual grasses are a major challenge to successful restoration in temperate and Mediterranean climates. Experiments to restore abandoned agricultural fields from exotic grassland to coastal sage scrub habitat were conducted over two years in southern California, U.S.A.

Abstract The enemy release hypothesis proposes that invasion by exotic plant species is driven by their release from natural enemies (i.e. herbivores and pathogens) in their introduced ranges.

Establishment of native grasses and their impact on exotic annuals in degraded box gum woodlands
Austral Ecology, 2017AbstractRestoration goals often involve the addition of new species to resident, degraded communities but in box gum woodlands such restoration is often constrained by competition from persistent exotic annuals that control critical ecological processes.

AbstractNative perennial grasses were once common in California prairies that are now dominated by annual grasses introduced from Europe. Competition from exotics may be a principal impediment to reestablishment of native perennial grasses. Introduced annual grasses, such as Vulpia myuros (zorro fescue), are often included with native perennial species

Abstract Invasion by Mediterranean annual grasses, such as Avena L. spp. and Bronms L. spp, is one of the major threats to temperate perennial grassland. This study investigated the effects of annual grasses and their litter on the species composition of a grassland near Burra, South Australia. The placement of annual grass litter on soil samples

Ecological Management & Restoration, 2011
Para Grass (Urochloa mutica (Forssk.) Nguyen) has invaded large areas of north Australian wetlands, out-competing native flora. Post-fire observations indicated that the native grass, Wild Rice (Oryza meridionalis Ng), re-established where gaps in Para grass mats had been created by burning.

Soil seed bank longevity of the exotic annual grass Bromus rubens in the Mojave Desert, USA
Journal of Arid Environments, 2013Abstract Although arid environments are often considered among the least invaded terrestrial biomes, the impacts of exotic plant species can be severe and long lasting. Bromus rubens (red brome) is an exotic annual grass species in the Mojave Desert known to outcompete native plant species, alter habitat, and promote accumulation of fuel that ...
