“…Response to Burning Foothills rough fescue plants had reduced yields the first and second growing seasons after spring burning, which is comparable to Redmann et al (1993) and Gerling et al (1995) for plains rough fescue. The yield reductions in the present study were related to burning resulting in shorter, lighter tillers, and occurred despite a 50% increase in tiller numbers in burned plants during the second year.…”

“…Plains rough fescue is shorter than foothills rough fescue and produces short rhizomes compared with the strongly tufted habit of the latter (Pavlick and Looman 1984). Most fire ecology studies in the Fescue Prairie have been conducted in the Parkland (Bailey and Anderson 1978, Bailey 1980, Redmann et al 1993, Gerling et al 1995). Although the foothills species of rough fes-…”

“…Rough fescue loses vigor when grazed during the growing season (Looman 1969). Burning may reduce rough fescue abundance Anderson 1978, Antos et al 1983) and productivity (Jourdonais and Bedunah 1990, Gerling et al 1995). While considerable research has addressed the effects of grazing on Fescue Prairie (Barker and Erickson 1971, Wright 1974, Willms et al 1985, no information is available on the cumulative effects of grazing following wildfire on foothills rough fescue plants.…”

“…The longevity of reduced current year standing crop in the Festuca communities is close to a 2 to 3 year reduction reported by Redmann et al (1993). On the other hand, current year production of plains rough fescue was not affected by burning in early April in Alberta (Gerling et al 1995).…”

AbstractThe effects of early spring burning on current year standing crop, litter, and total standing crop (current year standing crop plus litter) were examined in Festuca-and Stipa-Agropyron-dominated communities in central Saskatchewan over an 11-year period in a paired design with burned sites compared to adjacent control sites that were not burned. In Festuca communities current year standing crop was reduced in the first and third years (P = 0.010) after burning. Burning Stipa-Agropyron-communities tended to reduce current year standing crop, but the differences were not significant (P < 0.050) compared to control. Increasing precipitation stimulated current year standing crop after burning Festuca (P < 0.001, r2 = 0.33) and Stipa-Agropyron (P < 0.001, r2= 0.55) communities. Litter and current year standing crop were correlated (R2 = 0.24, P = 0.002) for Festuca indicating beneficial and detrimental effects of litter on production at low and high amounts, respectively. Litter and current year standing crop were not correlated (P = 0.964) for Stipa-Agropyron. In both communities total standing crop increased until about the eighth year after burning while the mass of litter appeared to reach a plateau around 11 years.

“…This agrees with previous observations by Moss & Campbell (1947) and Coupland & Brayshaw (1953), who reported the dominance of Festuca hallii in undisturbed grassland areas to the exclusion of other species. Festuca hallii produces a thick and persistent litter when undisturbed (Gerling et al 1995). Shading by litter cools the ground and, helped by high water holding capacity of the accumulated organic matter, suppresses evaporation.…”

Abstract. This paper describes the species composition of remnant grasslands in the aspen parkland region of Alberta and its relation to soil characteristics and small‐scale disturbance. Our findings are consistent with the centrifugal model of communities with Festuca hallii dominating undisturbed ‘core’ habitat and the composition of more ‘peripheral’ habitats varying in soil properties and in the magnitude of disturbance. Invasive non‐native species are not present in the core habitat and are present only in the disturbed sites, most abundantly in those with the highest soil nitrogen. The centrifugal model, as it applies to these remnant grasslands, differs from its previous application to wetlands and forests in that the core communities are not on the most fertile sites, but on the least disturbed. These findings have implications for the management of prairie remnants to exclude invasive exotic species.
