Grasslands and Plains

Over the last half-century, grassland bird populations have declined far more than any other bird group in North America. This is because native grasslands were largely replaced with croplands, and many remaining prairies are degraded. Land managers and conservation organizations are racing to preserve and restore these ecosystems to stem further loss of grassland birds. Given limited...

Sagebrush steppe ecosystems provide livelihoods for humans and essential habitats for wildlife, and thus management actions in these systems to promote wildlife persistence must strike a balance between human needs with those of wildlife. Across the western U.S., these landscapes have been heavily altered or lost through human activities, and climate change is expected to cause further...

As wildfire activity surges in the western U.S., managers are increasingly challenged by decisions surrounding managing post-fire environments. Changing fire regimes and warmer, drier post-fire conditions are increasing the likelihood of post-fire vegetation transitions, for example, from forest to grassland. Given the economic and ecological importance of these ecosystems...

A change in wildfire regimes and the expansion of invasive grasses are degrading sagebrush ecosystems, altering wildlife habitats, and threatening property and human livelihoods. In response, land managers often treat large areas of land with fuel reduction or post-fire seeding treatments in an attempt to reduce these risks. However, the trajectories of ecosystem change following...

Across the Navajo Nation, the negative effects of climate change are impacting soil and vegetation management practices to the detriment of ecosystem function, human health, cultural resiliency, and economic well-being. Conducting ecosystem restoration and shifting land management practices are critical elements of climate adaptation and dust mitigation strategies for the Navajo Nation...

Ecosystems experience stress from a number of factors, but a changing climate exacerbates those stressors and alters ecosystem and soil productivity, leading to degradation of wildlife habitat and agricultural productivity. Response to these enhanced stressors requires that farmers, ranchers, and wildlife managers have the necessary information and resources to guide adaptive management...

The National Park Service is responsible for managing livestock grazing on 94 locations across the country and several grazing management planning efforts for this work are underway. However, there is a recognized need to update grazing management plans to address potential future effects of climate change on related resources and practices. This is the second phase of a project that is...

Native American tribes are interested in managing their homelands for future generations, using both Indigenous and western science to make decisions in culturally appropriate ways. In particular, there is interest in strategic grazing management as a natural climate solution to strengthen the resilience of grasslands to a changing climate. This includes the restoration of free-ranging...

The Prairie Pothole Region is recognized as one of the most critical breeding habitats for waterfowl in North America and is used by an estimated 50–80 % of the continent’s breeding duck population. The ongoing acquisition program of the U.S. Fish and Wildlife Service National Wildlife Refuge System has conserved approximately 1.3 million hectares of critical breeding-waterfowl habitat...

Much of the biodiversity of the southeastern U.S. is found in grasslands, including meadows, prairies, glades, and savannas. These grasslands provide vital habitat to a variety of plants and animals, but many grassland types have undergone over 90% loss due to fire suppression and urban sprawl. The remaining grassland patches—remnants—now face emerging threats from invasive species and...

Aspen forests are considered keystone ecosystems, meaning that loss of aspen habitat would result in negative impacts to numerous plant and animal species. Aspen also provide important economic and social benefits, including drawing tourists, serving as potential fire breaks, improving local economies, and providing forage for wildlife and livestock. Ecologically-valuable aspen forests...

Climate change is already affecting ecosystems, and will likely trigger significant and permanent changes in both ecological and human communities. Such transformations are already occurring in the Arctic region of Alaska, where temperatures are warming at twice the global average and causing some ecosystems to transition to new states. Arctic warming has led to coastal erosion that has...
