Native Plants

Agricultural lands account for more than 50% of the lower 48 states and the effects of agricultural land use reach beyond individual fields and farms affecting terrestrial and migratory wildlife. Thus, it is important to know what long-term benefits US Department of Agriculture (USDA) conservation programs and policies have on wildlife habitat and the American public. The USDAs Conservation...

Public lands provide important habitat for many rare plants. However, public lands often need to accommodate many other uses, including traditional and renewable energy development, in addition to conservation. We are working with the Bureau of Land Management to coproduce ensemble habitat suitability models that can inform agency planning and permitting decisions that may impact rare plants.

Bison have played a key role in shaping the grasslands of the Great Plains for millennia. National Parks are a major last bastion for wild herds of the national mammal and symbol of the Department of the Interior. However, even as the National Park Service aims to maintain as natural as possible ecosystem conditions within its parks’ boundaries, managers regularly make decisions affecting their...

More than 100,000 ha of native tallgrass and mixed-grass prairies are managed by the U.S. Fish and Wildlife Service (FWS) in the northern Great Plains. Although prairies in this region evolved with grazing, fire, and climatic variability, management of FWS grasslands often has been passive and involved extended periods of rest. In 2008, the USGS and the FWS initiated a collaborative effort, the...

With scarcely 2% of native tallgrass prairie remaining today, it is imperative that we wisely manage what little remains to conserve prairie-dependent plants, pollinators, other animals and ecosystem processes. Two commonly used methods of prairie management are prescribed fire and conservation grazing. Either method may present trade-offs with respect to conservation of vulnerable plant, bee or...

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...

Since its inception in 1933, the U.S. Farm Bill has been one of the most influential federal policies for agriculture and food production. Provisions within the Farm Bill have profound influence on global trade, nutrition programs, commodity crop programs, rural communities, and land conservation. Northern Prairie’s research quantifies the impact on pollinator forage and health of USDA...

Midcontinent sandhill cranes occupy a large geographic area of central and western North America and northeastern Asia during breeding, winter, and migration. They are a species representing a unique convergence of multiple user groups with an interest in the continued health of this population. Tens of thousands of people view cranes during spring staging at the Platte River Valley in Nebraska...

Agriculture is the dominant land use on privately owned lands in the northern Great Plains of the United States. Management decisions on agricultural lands are influenced by a variety of policies and programs established by the federal government in periodic Farm Bills. In 1985, Congress passed the Food Security Act. Title XII of the Act established the Conservation Reserve Program or CRP, a...

Recent studies show that past and ongoing environmental changes have been substantial and have likely already affected conservation efforts in Hawai‘i. Much of the state has experienced substantial drying, including decreases in mean annual precipitation since the 1920s, longer rainless periods, and decreasing stream flow. Temperatures have been increasing in Hawai‘i for the last 40 years...

Initial studies suggest terrestrial Hawaiian plant species may be vulnerable to climate change. However, these models lack information on species-specific traits that affect ecological and evolutionary responses of species to climate change. Research is needed to refine current vulnerability models and apply these to Pacific Islands outside Hawai‘i.

Montane plant communities in widely separated intact natural environments of the world have responded to changes in precipitation and temperature regimes by shifting both margins and core distributional ranges upward in elevation. Reduced evapotranspiration rates in cooler climate zones at higher elevation may compensate for less precipitation and higher temperatures within species’ former ranges...
