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, transformation is a concer

The warming climate combined with a century of fuel build up (i.e. burnable plant materials found in the forest) due to fire suppression are driving megafires that threaten life and property and are severely altering ecosystems. Many of these fires are converting large areas of forest to shrub fields or grasslands, termed “ecological transformations.” Although uncharacteristically severe fires are

The long-term success of management efforts in sagebrush habitats are increasingly complicated by the impacts of a changing climate throughout the western United States. These complications are most evident in the ongoing challenges of drought and altered rangeland fire regimes resulting from the establishment of nonnative annual grasses. The Integrated Rangeland Fire Management Strategy recognize

Fires are becoming more extensive and severe in the West, and post-fire recovery is a challenge for communities as they adapt to a changing climate. Post-fire management can involve watershedrehabilitation, recovering valuable trees, and replanting to prevent forest loss and damage to watersheds. Land management agencies that make decisions may prioritize goals that differ from those of local popu

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 treatment are inc

Increasing wildfire activity in the western US poses profound risks for human communities and ecological systems. Recent fire years are characterized not only by expanding area burned but also explosive fire growth. In 2020, several fires grew by >100,000 acres within a 24-hour period. Extreme single-day fire spread events such as these are poorly understood but disproportionately responsible for

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. However, b

On remote Pacific islands and outer atolls, agroforestry (i.e., the cultivation and conservation of trees for agriculture) provides food security and income to local communities. Growing instability from climate change and invasive species like the coconut rhinoceros beetle threaten these resources. Actively managing and sustaining agroforestry resources requires detailed and up-to-date knowledge

There is a growing movement in the Pacific to decarbonize sea transportation. The transition to sustainable sea transport is projected to reduce socioeconomic vulnerability to external rises in oil prices while lowering carbon emissions in a period of intensifying climate change. With potential periodic global breakdowns in transport of fuel due to potential hazards such as global pandemics or pol

Moloka‘i has great wetland restoration potential in Hawaiʻi, but most remaining sites are highly degraded. The future of several endangered waterbirds and insects relies on restoring coastal wetland habitat that is resilient under sea-level rise and coastal flooding. Currently, managers lack background data on Molokaʻi to prioritize sites for restoration. In this project, Researchers will develop

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 decisions.

Areas along the Arctic coast are changing the fastest among all of Earth’s habitats due to climate change. The Arctic coast is a fragile ecosystem that provides habitat for migratory birds, endangered species, and species critical for local subsistence living. In this area, permafrost is thawing rapidly, changing how much and when water reaches rivers, ponds, lakes, wetlands and groundwater. In ad
