Land-use patterns surrounding greater prairie-chicken leks in northwestern Minnesota

Article Abstract:

Land-use patterns and patch characteristics surrounding greater prairie-chicken leks in the Agassiz Beach Ridges northwestern Minnesota were described using spatial analysis at a landscape scale. According to a multivariate analysis of variance, there is a strong dependence on land use by locations of greater prairie-chicken leks. Using discriminant function analysis and univariate analysis of variance, a number of land-use characteristics were most strongly associated with leks, such as smaller amounts and smaller patches of forest, smaller amounts of residential-farmstead, and greater amounts of Conservation Reserve Program lands.

Land-use patterns surrounding greater prairie-chicken leks in northwestern Minnesota

Article Abstract:

Land-use patterns and patch characteristics surrounding leks of greater prairie-chicken in the Agassiz Beach Ridges landscape in northwest Minnesota have been investigated using spatial analysis. It was possible to identify 389 unique greater prairie-chicken leks, which were used 866 times in the period 1986 to 1996. Results indicated that leks at the landscape scale were located in areas with less residential-farmstead, smaller areas of forest and larger amounts of Conservation Reserve Program (CRP) lands than anticipated. CRP may be significant, especially at temporary leks.

Identifying conservation-priority areas in a fragmented Minnesota landscape based on the umbrella species concept and selection of large patches of natural vegetation

Article Abstract:

The umbrella species concept and the selection of large patches of natural vegetation are common but relatively untested approaches for prioritizing conservation areas and the former has been tested in Minnesota. Conservation-priority areas in a fragmented landscape, Agassiz Beach Ridges, were identified based on selection of large patches of natural vegetation and the umbrella species concept to look at the habitat needs of the Greater Prairie Chicken, Tympanuchus cupido pinnatus.
