Sourcing plants for conservation and restoration: developing a risk assessment framework
Tallgrass prairie species are planted in a variety of settings for a variety of reasons. Much of the seed used for these plantings is produced commercially in agricultural-like conditions and can be contaminated by “weed seeds.” In this study, we are creating an analytical tool to assess the risk of inadvertently introducing weed seeds into a prairie planting. We purpose that increasing the...
Grazing resources for integrated conservation of bison and native prairie at Badlands National Park, South Dakota
Badlands National Park (BADL) contains one of the largest protected expanses of mixed-grass prairie in the United States, much of which supports a herd of nearly wild bison. The park nevertheless is too small to accommodate bison’s natural nomadic behavior, which in the past resulted in their ephemeral but intense influence on Great Plains grasslands. This research is assessing the spatial...
Developing evaluation and monitoring frameworks for tallgrass prairie reconstruction
Thousands of hectares of retired farmland are planted with tallgrass prairie species each year. If the methods used and resulting characteristics of these prairies are recorded, compiled, and analyzed, they can provide a valuable resource for evaluating seed mixes, planting methods, and post-planting management. Toward this end, collaborators in the Prairie Reconstruction Initiative, funded by the...
Integrated conservation of bison and native prairie at Badlands National Park, South Dakota
Badlands National Park contains the largest contiguous bison range in the core of the species’ historic range on the northern Great Plains. The park nevertheless is too small to accommodate natural movements of free-ranging bison. As a result, continual grazing by resident bison has supplanted intense-but-ephemeral grazing by nomadic bison. The herd also is currently too small to prevent gradual...
To control or not to control: response of pollinator communities to invasive plant management
If invasive plants are producing pollen and nectar used by native pollinators, what happens when a manager decides to control the invasive plant? Northern Prairie Wildlife Research Center is addressing this question and has found that pollinators are adept at changing their resource acquisition strategies as abundantly flowering invasive species decline. In addition, it appears that the invasive...
