Monitoring Standing Herbage Of The Sands And Choppy Sands Ecological Vegetation Types In The Nebraska Sandhills, Daniel W. Uresk Oct 2012

Monitoring Standing Herbage Of The Sands And Choppy Sands Ecological Vegetation Types In The Nebraska Sandhills, Daniel W. Uresk

Great Plains Research: A Journal of Natural and Social Sciences

A modified Robel pole with white and gray alternating bands (2.54 cm) was used to measure vegetation on sands and choppy sands ecological types in the Sandhills of Nebraska. Objectives were to determine the relationship between visual obstruction readings (VOR) and clipped standing herbage, develop guidelines for monitoring standing herbage, and provide sample size estimates. Visual obstruction measurements of standing herbage were linear, and regression coefficients were significant (P< 0.001) for 125 transects (R2 = 0.60, SE = 496 kg/ha). Clipped standing herbage ranged from 293 to 4389 kg/ha with a mean of 1,559 kg/ha. A minimum of four transects (20 stations/transect with four …

Assessment Of Conservation Reserve Program Fields Within The Current Distribution Of Lesser Prairie-Chicken, Dana Ripper, Megan Mclachlan, Theodore Toombs, Tammy Vercauteren

Great Plains Research: A Journal of Natural and Social Sciences

Populations of lesser prairie-chicken (Tympanuchus pallidicinctus) have declined by more than 90%, due primarily to the conversion of sand-sage and mixed-grass prairie to agriculture, overgrazing by domestic livestock, juniper encroachment, and fossil-fuel development. Degradation of native habitats has made restored cropland through the Conservation Reserve Program (CRP) potentially one ofthe best management options for lesser prairie-chicken. An estimated 1.4 million hectares of CRP exist within the lesser prairie-chicken range. We assessed 1,019 CRP fields representing more than 51,000 hectares within the current distribution of the lesser prairie-chicken. We sampled various grassland plantings including Farm Service Agency conservation practices …
