Summary of Methods: This article is a summary of 57 studies and papers examining traditional rangeland management strategies and the effect they have on the rangeland ecosystems in the Northern Great Plains and the dependent bird species.
Article Summary / Main Points: Heterogeneity is influenced by topography and soil patterns, interactions among plant species, and various disturbances across the landscape. Traditional rangeland practices increase homogeneity through uniform grazing of areas and on specific plants, reducing heterogeneity and biodiversity. Alternative management plans that promote heterogeneity through prescribed fires and focalized grazing create shifting mosaics, which enhance biodiversity.
Vegetation Types: All Vegetation Types
MLRA Ecoregions: Not Applicable
Agrovoc Control Words: Grazing systems Rangelands Birds
Article Review Type: Refereed
Article Type: Scientific Opinion
Keywords: prairie ecosystems, grazing, rangeland heterogeneity, biodiversity, great plains, prescribed fire
Annotation: This scientific opinion focuses on the Great Plains rangeland ecosystem but the findings are applicable to all rangeland management situations in western North America. Increased heterogeneity of an ecosystem increases the number of niches available for all wildlife species.
