This gif provides a preview of the output of the trends application and shows how a user can click between tabs in the tool to access the results. The tool allows the user to explore population abundance and growth rates within their area of interest across all population low points. The tool outputs are provided in map, figure, and table formats.

Allison Shipp, Deputy Regional Director for Science and Research and Saline Lake Ecosystems IWAA Project Manager, kicked off the Fall 2024 webinar series. This presentation gives an overview of the project and introduces topics that will be covered by the USGS research team throughout the webinar series.

This video captures a moment when USGS scientist Elizabeth Gallegos released 8 zoo-raised froglets into a stream, just one of several such reintroductions last summer. The long-term goal is to create 25 populations of a few hundred to a thousand frogs each. This summer, the team will revisit the sites to see how the frogs are doing.

Bats produce a variety of vocalizations that are used for navigation, feeding, and social communication. Most vocalizations are pitched well above the range of human hearing and are referred to as ultrasonic.

This is the call of the elusive Ashy Storm-Petrel (Oceanodroma homochroa). Ashy Storm-Petrels nest in burrows and crevices on offshore rocks and islands. To avoid predators, they only arrive and depart their island nests under the cover of darkness. That makes studying them pretty difficult.
