America’s diverse ecosystems are an asset to current and future generations by supporting economically and recreationally important fish, wildlife, and lands. Healthy ecosystems support people and nature, fostering prosperity and enjoyment for all.

This is a photo from our scientists working with the Yakama Nation to remove smallmouth bass and other invasive salmon-eating predators. The work involves taking fin clips, scales, diet samples, and tagging and releasing larger fish. This fieldwork will continue through late May 2025. The crew shown in the photos are Ben, Becky, Jeff, and Chloe.

Northwestern pond turtles are sexually dimorphic (females and males look different). One way to tell female and male turtles apart is that they often have different color patterns on their face and throats. Females have a more speckled throat, while males throats tend to be more solidly white/yellow.

These turtles are considered juveniles until they reach about 5 inches long. In this part of their range turtles remain juveniles and usually do not begin to reproduce until they are over ten years old.

This is a juvenile turtle. When they aren't in scared or in danger, northwestern turtles are very curious and will look towards movements and unusual sounds to figure out what is going on. They have excellent vision and hearing.

We glue transmitters onto their upper shells (called their carapace) using non-permanent epoxy. We will track these turtles until the transmitter battery dies (about 2 years) and soon after that the epoxy degrades, and the transmitter will fall off the turtle without harming the turtle or it's shell.

Northwestern pond turtles often return to the same area each winter for brumation. We tracked this turtle overwintering in almost the exact same area in the winters of 2023 and 2024. It's brumation location was only 11m apart between the two years.

Q: What’s the difference between PFOS and PFAS?
A: PFAS is a broad term that refers to a large group of man-made chemicals that contain fluorine atoms. This group includes thousands of different compounds and are highly resistant to degradation.

This turtle crossed a road leaving the reservoir and will cross it again to return to the reservoir. Road crossings present high risk to turtles and are a large source of mortality.

Boats and trailers can move invasive plants and animals between lakes. Aquatic invasive species are bad news and they need a plan for early detection and fast response.

Invasive swamp eel (Monopterus albus) collected in central Florida. Swamp eels are used as bait and in live food markets and have the potential to impact the ecology and economics of a waterbody.
