Planning for Wildfire: The Alaska CASC Focuses on Solutions

Research on the relationship between wildfire and other ecological disturbances, such as drought, is invaluable to resource managers planning for and adapting to the evolving threat that fire poses to humans, infrastructure, and ecosystems. Understanding how landscapes will respond to these shifts is key to adaptive management. In response to this need, Jeremy Littell, a USGS Research Ecologist at the Alaska CASC, has been working to contribute to our existing body of wildfire knowledge.  Learn more >>

Thinning Forests: Prescribing Fire Before Drought May Reduce Tree Loss

The results of a study partly funded by the Southwest CASC found that prescribed fire treatments may reduce tree loss during future droughts and bark beetle epidemics. This research suggests that expanding the use of managed fire under moderate fire-weather conditions, along with strategic thinning and prescribed burn treatments, may increase resilience across forests in the Southwest.  Learn more >>

Implications of Climate Scenarios for Badlands National Park Resource Management

South Dakota’s Badlands National Park hosts myriad natural and cultural resources that are sensitive to climate. Anticipating precisely how climate change will affect these resources, though, is difficult. North Central CASC researchers addressed this challenge by working with National Park Service personnel and other partners to implement a scenario planning approach that anticipates potential climate impacts on key resources and identifies management options for the park as well as adjacent federal and tribal lands.

Finding the Sweet Spot

Researchers at the University of Massachusetts Amherst, the U.S. Geological Survey and colleagues in New Hampshire, Virginia, Indiana, Montana and Canada found that by 2100, the region of maximum maple syrup flow will shift northward by hundreds of miles. This will benefit producers in Canada and lower production and quality in the Eastern United States. These results provide spatially-explicit projections for forest managers and syrup producers making decisions on the location and viability of management for maple syrup production. Learn more>>

 

WILDLIFE AND HABITAT

Introduced Species Dilute the Effects of Evolution on Diversity

Pacific Islands CASC researchers and partners explored how historical and recent ecological processes influence regional biodiversity across the Hawaiian archipelago. Their analysis showed that older islands, such as Kaua'i, had a greater number of rare species and native species than islands that formed more recently, such as Hawai'i Island. However, evidence also suggested that the contemporary introduction of non-native species to the ecosystem weakens the island age signal. These results show that local managers will need to consider both contemporary and historical drivers in their systems to maintain native biodiversity. Learn more >>

Exploring Climate Effects on Small, Biologically Diverse “Island” Ecosystems of the Southeast

Ecological “islands” in the Southeast include small habitat patches such as rock outcrops, bogs, springs, and sinkholes. These isolated habitat patches support plant and animal species that have adapted to the stressful environmental conditions found in these patches, and in many cases are confined to that ecosystem. Southeast CASC-supported researcher Jennifer Cartwright developed a framework for anticipating, studying, and managing climate-change impacts in these unique ecosystems. Learn more >>
