Plant Interspaces Resulting From Contrasting Grazing Management in Northern Mixed-Grass Prairie: Implications for Ecosystem Function
We assessed plant interspaces in July 2007 using continuous line intercepts in twice-replicated pastures of northern mixed-grass prairie with contrasting grazing treatments: 1) long-term (25 yr) heavily grazed, dominated by the bunchgrass blue grama (Bouteloua gracilis), and 2) ungrazed, dominated by the rhizomatous grass western wheatgrass (Pascopyrum smithii). The number of plant interspaces ...
متن کاملGrazing Effects on Carbon Dynamics in the Northern Mixed-Grass Prairie
The role of rangelands in the regulation of atmospheric CO2 concentrations is a critical issue in global climate change research. Rangelands are complex ecosystems that occupy about 50% of the land area in the world and USA. We studied the effects of seasonal grazing on CO2 flux on small plots located on a silty range site in the northern mixed-grass prairie with an Eapa fine loam soil. Treatme...
متن کاملPrescribed fire and grazing effects on carbon dynamics in a northern mixed-grass prairie
Rangelands are complex systems that occupymore than 50% of the land area in theworld. Carbon cycling on rangelands is generally understood, but details concerning agricultural management practices of prescribed fire and grazing are not well defined. Field experiments were conducted on northern mixedgrass prairie in eastern Montana with undisturbed, burned, and grazed treatments established in 2...
متن کاملLong-Term Abundance of Breeding Songbirds During Restoration of Northern Mixed-Grass Prairie
There are no published, long-term accounts of responses of grassland passerine birds to the restoration of northern mixed-grass prairie through combined use of fire and grazing. During 1979-2001, we assessed abundance of passerine birds (9 grassland species and 1 shrub-associate species) on 2 brush-invaded, mixed-grass prairie tracts at Lostwood National Wildlife Refuge in northwestern North Da...
متن کاملPredicting Nitrogen Content in the Northern Mixed-Grass Prairie
Forage quality and quantity are important factors affecting livestock production from grazing lands. ‘‘Greenness’’ has been proposed as an indicator of herbage quality in semiarid environments, particularly nitrogen (N) content. The objective of this study was to assess the potential of estimating N content of forage using dead:green ratios and accumulated growing-degreedays (AGDD). Standing cr...
