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.

Trend estimation calculated from seven nadirs defining six unique periods of complete population oscillation
linkTrend estimation calculated from seven nadirs defining six unique periods of complete population oscillation. Purple lines indicate periods of erroneous inference about population trend. Green lines indicate nadir-to-nadir inference and more accurate trend estimation.

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.

This video shows a California tiger salamander finding its way to an underpass designed to help amphibians and reptiles cross the road safely, with the help of a "turn-around" that helps guide the salamander back in the right direction as it travels away from the underpass.

Do you have what it takes to be a bat biologist? USGS bat researchers are counting Townsend’s big eared bats to monitor how their populations are doing. Watch the video to try your hand at a bat count and see how your skills compare to a USGS scientist!

In this video, you can hear the honks and quacks of geese and ducks ring through the air, as birds fly in every direction above a wetland. This video was captured at Sacramento National Wildlife Refuge in November 2019, not long after geese and ducks began to arrive to spend the winter in the California Central Valley.

Tidal marshes exist as a transitional environment between the land and sea, and provides habitat to fish and wildlife, protects human developments from coastal flooding, and stores carbon at high density, among other important ecosystem services.

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.
