Association Of Soil Conditions And Grass Species With Variable Cover Of Leafy Spurge, Terence P. Mcgonigle, Jeremy L. Timmer
Association Of Soil Conditions And Grass Species With Variable Cover Of Leafy Spurge, Terence P. Mcgonigle, Jeremy L. Timmer
The Prairie Naturalist
Variation in soil conditions and grass cover was assessed across a range of leafy spurge (Euphorbia esula L.) cover values on a sandy rangeland in Manitoba, Canada. Soil conditions varied by site but not in relation to cover of leafy spurge. We observed a significant negative relationship between total grass cover and increasing cover of leafy spurge. Only porcupine grass (Hesperostipa spartea [Trin.] Barkworth) had a negative relationship with leafy spurge, falling from high cover at low weed occurrence to only trace levels at the highest leafy spurge abundance. Neither prairie Junegrass (Koeleria macrantha [Ledeb.] Schult.), rough …
Potential Impacts Of Bison Wallows On A Restored Tallgrass Prairie Community, Kimran Miller, Johanna Foster, Kristen Nielsen, Mary O'Loughlin
Potential Impacts Of Bison Wallows On A Restored Tallgrass Prairie Community, Kimran Miller, Johanna Foster, Kristen Nielsen, Mary O'Loughlin
The Prairie Naturalist
When bison (Bos bison) repeatedly roll on the ground, they denude vegetation and create wallows (semi-permanent bare areas) that alter the native prairie plant community. Responses to these wallow-related disturbances are not as well documented in restored prairies. From 1 June to 1 September 2010 and from 3 June to 6 August 2011, we examined potential responses at Neal Smith National Wildlife Refuge, a restored prairie with resident bison. We hypothesized that plants and beetles would vary along a disturbance gradient. Our predictions were: (1) near wallows, plants with weedy lifestyles would have highest cover and biomass compared …
