Landscapes

Wildfire, drought, and insects are reshaping forests in the Western United States in a manner that is being exacerbated by warming temperatures. Disturbance events such as these can significantly alter the amount of land that is covered by forest in an area or region. Consequently, changes in forest cover from disturbance can impact water runoff conditions leading to dangerous flooding...

The nursery industry grows, markets, and sells plants for ecological restoration as well as urban and suburban landscaping. The Northeast U.S. is a patchwork of small, mostly private land holdings, where the choices of nursery professionals influence the composition of current and future ecosystems. Unfortunately, the nursery industry focuses predominantly on non-native plants. This...

Vegetation transformations after wildfires are a growing issue for forest and shrubland managers in the Inland Pacific Northwest. Severe fires combined with persistent drought and invasive species can slow or prevent the recovery of burned forests and shrublands to their pre-fire states, resulting in ecological, economic, and cultural losses. Forests may be converted to shrub fields or...

High elevation red spruce forests are among the most iconic and visited natural communities in the High Alleghenies of the Central Appalachian Mountains. These ecosystems provide many services such as clean water and carbon sequestration, as well as habitat for species of high conservation concern, i.e., the eastern brook trout, the northern goshawk, and the northern flying squirrel...

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...

Project Overview Climate change threatens keystone plant communities and insects that make up the base of functional food webs, but restoration practitioners struggle to factor climate considerations into restoration projects for a number of practical reasons. Researchers supported by this National CASC project will create a trait-based plant vulnerability assessment to guide restoration

Climate change is contributing to an increase in wildfire activity in the western United States, including the Blue Mountains and Eastern Cascades Slopes and Foothills of the Inland Northwest. Some forest ecosystems are changing from forest to non-forest because of severe fires, a hot and dry climate, and/or the absence of a viable seed source. On sites impacted by wildfire, managers are...

Hawaiʻi is often referred to as the endangered species capital of the world, with hundreds of species at risk. While Hawaiian forest birds have garnered attention in the global conservation community as they face imminent extinction due to climate change, climate also poses serious challenges to hundreds of other Hawaiian species. Although traditional recovery plans provide meaningful...

Black ash wetlands occupy over 1.2 million hectares of forest in the Great Lakes region, providing habitat for unique and diverse wildlife communities. In these wetlands, black ash trees are a foundational species, regulating all aspects of ecosystem function, and are also an important cultural resource for Native Americans, specifically for basket-makers. Black ash wetlands are...

Extreme weather events (such as floods, ice storms, tropical cyclones, and tornadoes) are increasing in frequency and causing severe consequences throughout the U.S. and particularly in Louisiana. These natural disasters are especially devastating for farmers, whose livelihoods depend on the environment. Most climate research and extension outreach focus on large-scale farmers and tend...

Wildfire is a natural and essential process in forest ecosystems, but characteristics of fire regimes that have shaped these landscapes over long time scales are changing with climate change and human activities. In some places, changes in fire size, frequency, and severity threaten to degrade essential ecosystem services that produce clean air and water, fertile soil for crop and wood...

Millions of acres of California’s forest cover have been lost due to severe wildfire and drought mediatedinsect outbreaks. These acres may not grow back as forests without management action, which could negatively impact carbon sequestration, access to clean drinking water, wildlife habitat and recreation opportunities. Various factors, including limited regeneration potential, hotter...
