Birds

Climate change, invasive species, and diseases are threatening Northeastern forests, with consequences for bird populations and carbon storage. Researchers supported by this Northeast CASC project will evaluate whether already-implemented climate adaptation strategies in the region have been effective at protecting bird habitat and what the implications of carbon storage have been. The...

Project Overview Infectious disease poses a growing threat to wildlife and human health, and managing disease threats is complicated by climatic changes that can change levels of disease risk. Researchers supported by this North Central CASC project will co-develop a method to rank wildlife disease threats under climate change, providing critical useable information to Montana’s wildlife

Infrastructure development and climate change pose significant threats to migratory bird populations by altering their distributions and habitat. This Northeast CASC-supported research team will use citizen-science and structured monitoring data to identify current and future areas that are important for migratory bird species across the Northeastern US. Researchers will produce high...

Project Overview In the Midwest, climate change is forcing birds to shift their ranges, raising concerns about how well protected areas provide refuge for vulnerable bird species. Researchers supported by this Midwest CASC project will use two decades of bird monitoring data to evaluate how protected areas in the Upper Great Lakes region support birds now and in the future under changing...

Project Overview Hawaiian honeycreepers face numerous threats related to sea level rise, increasing storm frequency, erosion and invasive species. These impacts can alter their habitat, making it unsuitable and detrimental to their already small populations. Researchers supported by this Pacific Islands CASC project will create additional populations of a Hawaiian honeycreeper species by

As part of the State Wildlife Grant Fund, states are required to submit State Wildlife Action Plans (SWAPs) every 10 years detailing habitats, species, and conservation plans. However, incorporating climate change in SWAPs isn’t required and capacity to do so is limited at most state agencies, resulting in varied consideration of climate change impacts. In support of the revisions to...

Project Overview Climate change is altering the timing of natural seasonal events (phenology). This is manifesting in many ways including altering patterns of bird migration between Molokaʻi and southcentral Alaska. Researchers supported by this Pacific Islands CASC project will combine Traditional Ecological Knowledge (TEK) and conventional science to track these phenological shifts...

Mosquito-borne disease is the biggest threat to Hawai‘i’s remaining native forest birds, of which more than half are threatened or endangered. Currently, disease-carrying mosquitoes are unable to move into colder high-elevation forests, but as the islands warm due to climate change, mosquitoes are steadily moving into the last native bird strongholds. Mosquito suppression efforts are...

Project Overview Climate change threatens plants and animals across the US, making it important to have tools that can efficiently assess species’ vulnerabilities. In this project, CASC scientists and NatureServe are collaborating to update a popular Climate Change Vulnerability Index to include the latest scientific data, improved metrics, and new user-friendly technology. The tool will...

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...

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...

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...
