“…Quercus havardii (Fagaceae) shrublands (Boyd and Bidwell 2002;Harrell et al 2001), and North American Prosopis glandulosa (Fabaceae) savanna (Ansley et al 2008). Low mortality resulting from fire, as indicated by no change in density and their rapid recovery by resprouting, is the likely mechanism explaining the lack of a relationship between time since fire and A. filifolia density in our study of plants exposed to one and two fires.…”

In North America, most Artemisia (Asteraceae) shrub species lack the ability to resprout after disturbances that remove aboveground biomass. We studied the response of one of the few resprouting Artemisia shrubs, Artemisia filifolia (sand sagebrush), to the effects of prescribed fires. We collected data on A. filifolia density and structural characteristics (height, canopy area, and canopy volume) in an

“…For summaries, herbaceous cover was grouped into 5 functional groups: Sandberg bluegrass (Poa sandbergii Vasey), tall tussock perennial grass, annual grass, perennial forbs, and annual forbs. The purpose of using functional groups was to combine species that respond similarly to environmental perturbation and to reduce data to a simpler form for analysis and presentation (Boyd and Bidwell 2002). We tried to use hierarchical cluster analysis (PC-ORD 1999) to define associations, but were unsuccessful.…”

The Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) alliance is the most extensive of the big sagebrush complex in the Intermountain West. This alliance provides critical habitat for many sagebrush obligate and facultative wildlife species and serves as a forage base for livestock production. There is a lack of information that describes vegetation cover values, characteristics, diversity, and heterogeneity of the Wyoming big sagebrush alliance. This study describes vegetation cover values and defines distinct associations for intact, late-seral Wyoming big sagebrush plant communities across part of its northwestern range. We sampled 107 Wyoming big sagebrush plant communities. Total herbaceous cover values were variable among sites with differences between sites exceeding 700%. Mean sagebrush cover was 12.3% with 90% of the sites producing 6% to 20% cover. Tall forb (. 18 cm) cover averaged 1.9% and 90% of the sites varied between 0.2% and 5.6% cover. Five associations delineated by dominant perennial bunchgrass species were identified: ARTRW8 (Wyoming big sagebrush)/PSSP6 (Pseudoroegneria spicata ResumenLa alianza de la artemisa grande de Wyoming (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) es el complejo de artemisa mas extenso del oeste intermontano. Esta alianza proporciona há bitat crítico para muchas especies específicas y generalistas de artemisa y sirve como forraje bá sico para la producció n ganadera. Existe muy poca informació n que describe el valor de la cobertura vegetal, características, diversidad, y heterogeneidad de la alianza de la artemisa grande. El presente estudio describe valores de cobertura vegetal y define las diferentes asociaciones en comunidades intactas de plantas serales de artemisa grande en el rango noroeste. Muestreamos 107 comunidades de plantas de artemisa grande de Wyoming. El total de los valores de cobertura herbácea fueron variables entre sitios con diferencias que excedían el 700%. La cobertura promedio de artemisa fue de 12.3% con un 90% de los sitios con un rango de cobertura entre 6% y 20%. La cobertura de hierbas altas ( .18 cm) promedió 1.9% y el 90% de los sitios variaron en cobertura entre 0.2% y 5.6%. Se identificaron cinco asociaciones delineadas por especies perennes dominantes de pastos: ARTRW8 (Artemisa grande de Wyoming)/AGSP (Agropyron spicatum [Pursh] Schibn. & Smith, bluebunch wheatgrass), ARTRW8/STTH (Stipa thurberiana ajenjo, Thurber's needlegrass), ARTRW8/FEID (Festuca idahoensis Elmer, Idaho fescue), ARTRW8/STCO2 (Stipa comata Trin. & Rupr., needleand-thread), and ARTRW8/AGSP-STTH (una co-dominancia de bluebunch wheatgrass and Thurber's needlegrass). Nuestros resultados sugieren que cuando los valores propuestos para sabio urogallo se aplican como requisitos promedio o por encima del mismo, estos exceden el potencial ecoló gico de muchos de los sitios muestreados.

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

2010

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.
