Energy and Wildlife

Covering studies published October 2023 through September 2024

Public lands provide important habitat for many rare plants. However, public lands often need to accommodate many other uses, including traditional and renewable energy development, in addition to conservation. We are working with the Bureau of Land Management to coproduce ensemble habitat suitability models that can inform agency planning and permitting decisions that may impact rare plants.

Threatened humpback chub are a native fish found only in the Colorado River Basin. Once found in warm-water canyons in the Basin, the largest population now persists in the Colorado River in Grand Canyon National Park, downstream of Glen Canyon Dam and Lake Powell, the reservoir upstream, created by the dam.

Pregnant polar bears enter maternity dens in October/November, give birth to cubs in December/January, and exit dens in March/April. Historically, most polar bears from the Southern Beaufort Sea (SBS) population constructed maternity dens on the sea ice. Over the last three decades, as sea ice has become thinner and prone to fragmentation, there has been a landward shift in the distribution of...

A massive die-off of Common Murres was documented in the Gulf of Alaska (GOA) during the fall and winter of 2015-2016 in association with a record-breaking marine heat wave in the GOA.

USGS researchers will characterize the ecology of benthic invertebrates associated with deep-sea environments and broader food-web dynamics within hardground features, seeps, and adjacent soft sediments. This project will provide important information regarding deepwater benthic habitats, such as chemosynthetic communities and deep-sea corals, that could be affected by offshore wind development.

Renewable energy development is expanding in southwestern deserts, including in Arizona. Energy developers look to resource management agencies to provide siting guidance on public lands where there might be conflicts with wildlife. Often, agency guidance considers species of conservation concern and economic importance, but information on comprehensive vertebrate biodiversity has been hard to...

The United States Large-Scale Solar Photovoltaic Database (USPVDB) provides the locations and array boundaries of U.S. ground-mounted photovoltaic (PV) facilities with capacity of 1 megawatt or more. It includes corresponding PV facility information, including panel type, site type, and initial year of operation. The creation of this database was jointly funded by the U.S. Department of Energy...

There are more than 92,000 dams in the United States, of which at least 3% of these produce hydropower. Hydropower projects create renewable energy but also can alter habitats, restrict upstream and downstream movements of fishes and other aquatic organisms, and may stress, injure or kill migrant fishes and other aquatic organisms. In addition, there are more than 5 million culverts and other road...

The Hawaiian Hoary Bat ( Lasiurus semotus) or ʻōpeʻapeʻa is the only extant land mammal native to the Hawaiian archipelago and is listed as endangered due to apparent population declines, and a lack of knowledge concerning its distribution, abundance, and habitat needs. This study is designed to apply molecular techniques to document demographic information, assess genetic variability, describe...

Renewable energy development, such as solar and wind energy, is growing in the United States and is expected to continue expanding for the foreseeable future. However, renewable energy infrastructure can be a risk to some wildlife including threatened and endangered species. Wildlife managers and energy developers need wildlife risks to be assessed and effective strategies to mitigate those risks...

Native and desired nonnative fish downstream of Glen Canyon Dam are food limited—meaning that if more or larger invertebrate food items were available, there would be more and larger fish. Aquatic insects have complex life cycles that include egg, larvae, and pupal stages that are aquatic while adults have wings and are typically terrestrial. Aquatic insects are a fundamental component of river...
