Grazing management effects on plant species diversity in tallgrass prairie
A 6-year study was conducted in tallgrass prairie to assess the effects of grazing management (cattle stocking densities and grazing systems) on plant community composition and diversity. Treatments included sites grazed season-long (May to October) at 3 stocking densities (3.8, 2.8, and 1.8 hectares per animal unit), ungrazed control sites, and sites under a late-season rest rotation grazing s...
متن کاملTallgrass Prairie: Remnants and Relicts
The tallgrass prairie once was continuous throughout the eastern Great Plains. Now, scattered remnants remain. The distribution of some of the most interesting and socially valuable remnants occur along the base of the Rocky Mountains as relicts from a past era. When the species composition of these Colorado grasslands is compared with that of the eastern tallgrass prairie by an index of simila...
متن کاملThe ecological significance of tallgrass prairie arthropods.
Tallgrass prairie (TGP) arthropods are diverse and abundant, yet they remain poorly documented and there is still much to be learned regarding their ecological roles. Fire and grazing interact in complex ways in TGP, resulting in a shifting mosaic of resource quantity and quality for primary consumers. Accordingly, the impacts of arthropod herbivores and detritivores are expected to vary spatia...
متن کاملTechnical Note Field Test of Digital Photography Biomass Estimation Technique in Tallgrass Prairie
Fuel loading information is important for prescribed fire planning, evaluating wildfire risk, and understanding fire effects in grassland. Yet fuel loads in grasslands often go unmeasured because of the time required to clip plots and process samples, as well as limited access or proximity to a drying oven. We tested the digital photography biomass estimation technique for measuring fuel load i...
متن کاملPartitioning of Nitrogen over Five Growing Seasons in Tallgrass Prairie
Annual spring burning of tallgrass prairie increases plant biomass production despite losses of N and lower net N mineralization. To better understand how burning influences the cycling of N in prairie, '5N was injected to soil as NH4+, and the partitioning between plant and soil N pools was followed over five growing seasons in annually burned and unburned prairie. Applied '5N was rapidly immo...
