Birds are appreciated and enjoyed by thousands of people and also play important roles in the ecosystem as predators, prey, and pollinators. Alaska provides important breeding ground for hundreds of migratory bird species that travel thousands of miles in their annual migrations between breeding and wintering spots. Understanding how climate and land use changes affect migratory bird populations is crucial; however this information is also very difficult to collect. Migration routes expose birds to a wide range of landscapes and habitats, which are often experiencing varying degrees of climate and land use change (e.g. warmer temperatures or increased housing developments). Moreover, climate change in the future...

Background information. In the late 1800s through the early 1900s, nearly all of the area that is now the Crab Orchard National Wildlife Refuge (Crab Orchard NWR) was either logged for timber or cleared and converted to other uses, particularly agriculture. By the 1930s, soils in the area were depleted and severely eroded. Additional clearing and development ensued with the establishment of the Illinois Ordnance Plant during World War II. In 2014, as part of the effort to restore Crab Orchard NWR lands to benefit wildlife, the refuge undertook the Hampton native prairie restoration project to convert a 62-acre nonnative cool-season hay field into a native warm-season grassland. The primary benefit of this restoration...

In California, the near-shore area where the ocean meets the land is a highly productive yet sensitive region that supports a wealth of wildlife, including several native bird species. These saltmarshes, mudflats, and shallow bays are not only critical for wildlife, but they also provide economic and recreational benefits to local communities. Today, sea-level rise, more frequent and stronger storms, saltwater intrusion, and warming water temperatures are among the threats that are altering these important habitats. To support future planning and conservation of California’s near-shore habitats, researchers examined current weather patterns, elevations, tides, and sediments at these sites to see how they affect...

The Hawaiian Islands are home to some of the world’s most culturally valuable but imperiled forest birds, including brightly colored native honeycreepers, many of which are threatened or endangered. One of the major threats these birds face is avian malaria, which is spread by a species of introduced mosquito and can have death rates exceeding 90 percent. For decades, upper mountain forests have provided refuge for Hawaiian forest birds because mosquitoes (and thus the disease) could not survive the cooler temperatures. However, warming associated with climate change could change this. Scientists used climate data and an epidemiological model to evaluate the future impacts of avian malaria on Hawaiian forest birds...

Phenology, or the timing of the annual cycles of plants and animals, is extremely sensitive to changes in climate. We know that plants and animals may adjust the timing of certain phenological events, such as tree flowering or migration, based on changes in weather. However, it’s important that we also understand how the timing of phenological events is changing over longer time frames, as climate conditions change. While some species appear to be adjusting to the increase in unseasonal temperatures, drought, and extreme storms that have come with climate change, not all species are responding at the same speed or in the same ways. This can disrupt the manner in which species interact and the way that ecosystems...

FY2015This effort complements a project, supported by the Joint Fire Science Program, to explore relations among cheatgrass-driven fire, climate, and sensitive-status birds across the Great Basin. With support from the NW and SW Climate Science Centers and the GB CESU, we aim to engage managers at local, state, and regional levels, and to involve both field-level and director-level personnel, during all stages of the proposed project. Our methods of engagement are intended to save managers time and decrease some of the uncertainty in planning and decision-making rather than to create additional pressures on managers time. We will conduct field visits, workshops, and interactive briefings to build trust and increase...

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 resources, bird habitat models are needed to help managers prioritize where conservation efforts will be most effective. In addition to habitat loss and degradation from land use change, altered fire regimes, and woody encroachment, increasing greenhouse gas emissions will likely change temperatures and rainfall patterns across North...

This project used the NatureServe Climate Change Vulnerability Index tool to assess vulnerability of 140 bird species that breed in the Sierra Nevada and will develop a peer-reviewed Climate Change Adaptation Strategy for Sierra Nevada bird species that are most vulnerable to climate change. The Strategy provides recommendations for actions that managers can take now and in the future to bolster resilience to climate change.

Spruce-fir forests and associated bird species are recognized as some of the most vulnerable ecosystems and species to the impacts of climate change. This work capitalized on a rich suite of long-term data from these ecosystems to document recent trends in these forests and their associated bird species and developed tools for predicting their future abundance under climate change. Findings from this work indicate declining trends in the abundance of spruce-fir obligate birds, including Bicknell’s Thrush, across the Lake States and New England. In contrast, montane spruce-fir forests in the White and Green Mountains of New England exhibited patterns of increasing abundance, potentially due to their recovery from...

State wildlife agencies and their partners use State Wildlife Action Plans to coordinate and guide management activities aimed at protecting species. To do so, they must identify factors putting species and their habitats at risk. Current and future climate change is one such factor. To succeed, management actions need to account for impacts of climate change on species today and in the future as climate change accelerates in coming decades. Researchers use modeling approaches to simulate and understand how future climate change will impact species. In contrast, natural resource managers involved in wildlife action plans tend to favor index-based scoring approaches to understand the risks to and vulnerability...

In 2019 a pilot study was conducted to determine the feasibility of using distance sampling to estimate density and population size of goose and eider nests on the Yukon-Kuskokwim Delta (YKD). Distance sampling (Buckland et al. 2001) is a common and well-understood method to estimate wildlife population size or density, especially for sparse and hard-to-detect populations. A main advantage of distance sampling is that it accounts for imperfect detection and gives precise estimates for a given level of effort relative to other methods. The objectives for the pilot project in 2019 was to (1) determine if distance sampling is feasible on the YKD, (2) determine what aspects of the field protocol need to be changed or...

Moloka‘i has great wetland restoration potential in HawaiÊ»i, 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 MolokaÊ»i to prioritize sites for restoration. In this project, Researchers will develop a comprehensive dataset and create a prioritization plan for coastal wetland restoration. The team will work closely with project partners and stakeholders to develop a well-vetted plan to support endangered species and meeting community needs. Existing maps and spatial data about the MolokaÊ»i landscape will be compiled...

Upland Sandpiper is one of many declining shorebird species (-4.6%/year in Alaska; Ziolkowski et al. 2023) which breed on military and adjacent lands in Alaska. Western and eastern populations are small and unstable, and the species is endangered at the state level in several eastern U.S. states (Houston et al. 2023). Though there has been considerable work with Upland Sandpipers in their core, central U.S. breeding areas, this is the first dedicated study of Upland Sandpipers in Alaska. The objectives are to resight, band, and track Upland Sandpiper at breeding sites in Delta Junction, AK and Donnelly Training Area (TA 501 & TA 511) to estimate vial rates, determine migratory connectivity, and determine important...

The U.S. Northern Rocky Mountains support a large number of native wildlife species, and survival of these populations depends on connected landscapes to support current migration and dispersal, as well as future shifts in species’ ranges. However, habitat fragmentation and loss threaten these connections. Land and wildlife managers across the U.S. are faced with decisions focused on reducing risks, like those from habitat fragmentation, to wildlife, ecosystems, and landscapes. Establishing connections between natural landscapes is a frequently recommended strategy for these managers to help wildlife adapt to changing conditions. Working in partnership with state and federal resource managers and private land...

Today, sea-level rise, more frequent and stronger storms, saltwater intrusion, and warming water temperatures are among the threats that are altering these important habitats. Much of the existing research on anticipating the effects of changing conditions on coastal ecosystems relies on global or regional scale data, meaning that the detailed information necessary for local-scale...

Species are on the move as they respond to climate change. This includes many native species, but also species with high costs to society such as disease vectors, pests, and nonnative invasive species (an invasive species is a species that is not native to a specific location but is spreading with the tendency of causing damage to native plants and animals). Currently there are hundreds of invasive species with relatively restricted ranges in the southeastern U.S., but as the climate changes these species are expected to expand their ranges to new regions. It is important to understand if and how these species might move and what actions we can take to lessen their impact on species and habitats. To achieve this...

Duck banding data is integral to the Adaptive Harvest Management (AHM) process that uses both band recovery data and aerial breeding population survey data to establish hunting regulatory packages each year. Mallard banding in Alaska is one component of the process to set hunting regulations for ducks in the Pacific Flyway by providing harvest rate estimates for the Western Mallard AHM model (U.S. Fish and Wildlife Service 2021). Harvest rate is used in coordination with breeding population size estimates from the Waterfowl Breeding Population and Habitat Survey to determine the optimal regulatory strategy (liberal, moderate, restrictive, or closed) for dabbling ducks in the Pacific Flyway. Each regulatory alternative...

Migratory birds may be hit especially hard by climate change – particularly waterbirds that depend on wetlands as resting and feeding sites during their journey between breeding and non-breeding grounds. California’s Central Valley and the interior basins of southeastern Oregon and northeastern California provide some of the most critical wetlands resources to migratory waterbirds in the western U.S. However, these wetlands rely heavily on snow pack and precipitation for water supply, both of which have already decreased due to climate change. Of further concern is the fact that drought conditions resulting from climate change could exacerbate existing water allocation issues in the region. Researchers are examining...

Recent changes in climate are having profound effects on many fish and wildlife species, and projections suggest that those trends are likely to continue. Changing climate conditions have the potential to transform ecosystems, which impacts not only fish and wildlife but also human communities, which rely on ecosystems for important goods and services such as food and water filtration. Strategies that are implemented by natural resource managers now have the potential to help minimize the impacts of changing climate conditions on species and ecosystems going forward. However, substantial knowledge gaps remain regarding how species might respond to changes in climate, such as whether these changes will lead to ecosystem...
