“…Propagule availability was probably similar for all plots, given the small size of the plots and their proximity to surrounding intact shrub/grass communities. Other authors (e.g., Boyd and Davies, 2010;Eiswerth et al, 2008) found that presence of shrubs in the pre-disturbance environment was associated with decreased annual grass abundance and increased establishment of seeded perennial grasses post-disturbance, even if the shrubs were removed by disturbance. This role of shrubs in reducing annual grasses was not evident in the present study under conditions of natural recovery as evidenced by the high level of cheatgrass abundance in the CR treatment (which had previously contained shrubs).…”

“…Ex Link] Schult) and Siberian wheatgrass (A. fragile [Roth] P. Candargy), are commonly seeded after wildfires (Eiswerth et al, 2009;Knutson et al, 2014) and exotic annual grass control Nafus and Davies, 2014). These introduced bunchgrasses are often selected instead of native bunchgrasses because they are more available, cost less, and establish better (Arredondo et al, 1998;Eiswerth et al, 2009;Boyd and Davies, 2010). Crested wheatgrass has also been selected because it is highly competitive and can be seeded around infestations to limit the spread of medusahead .…”

“…However, considering the negative impacts of T. caput-medusae on biodiversity, wildlife habitat, and livestock forage production (Davies and Svejcar 2008), it may be an acceptable risk to use A. desertorum to help impeded the spread of T. caput-medusae. Furthermore, Agropyron desertorum also provides similar wildlife habitat, nutrient cycling, and ecosystem functions as native bunchgrasses in these ecosystems (Eiswerth et al 2009). Because of the potential for non-native to cause similar problems as exotic invaders, careful consideration of the impacts of non-native plant species that could potentially be used to contain invasive plant infestations is imperative to prevent unintended negative consequences.…”

Non-native competitive perennial grass impedes the spread of an invasive annual grass

Invasive plants are degrading wildlands around the globe by displacing native species, reducing biodiversity, and altering ecological functions. The current approach of applying herbicides to invasive plants in wildlands has not been effective at curtailing their expansion and, in certain circumstances, may do more harm than good. Preventing the spread of invasive species has been identified as an important strategy to protect wildlands. However, few prevention strategies have actually been tested. We hypothesized that establishing competitive vegetation next to infestations would increase the biotic resistance of the plant community to invasion and decrease the invasive species propagule pressure beyond the competitive vegetation. To evaluate this, we established twelve competitive vegetation barriers in front of invasive annual grass, Taeniatherum caput-medusae (L.) Nevski, infestations. The nonnative perennial grass Agropyron desertorum (Fisch. ex Link) Schult. was seeded into plant communities adjacent to the infestations to create the competitive vegetation barriers. Soil nutrient concentrations and the spread of T. caput-medusae were compared between where A. desertorum was seeded and not seeded (control treatment) 3 years after treatment. Less T. caput-medusae and lower soil ammonium and potassium concentrations in the competitive vegetation barrier than control treatment (P B 0.01) suggest that establishing competitive vegetation increased the biotic resistance of the plant communities to invasion. Taeniatherum caput-medusae cover and density in the plant communities protected by the competitive vegetation barrier (locales across the barriers from the infestations) were *42-and 47-fold less, respectively, than unprotected plant communities (P \ 0.01). This suggests that invasive plant propagule pressure was decreased in the plant communities protected by competitive vegetation barriers. The establishment of competitive vegetation around infestations may be an effective strategy to prevent or at least reduce the spread of invasive plant species.
