A record number of captive-born endangered Mexican gray wolf pups have been placed in wild dens this year. It’s a process known as cross-fostering and is designed to increase genetic diversity in the struggling species. KNAU’s Ryan Heinsius reports.

Here’s a fish story for you: what if you could get paid to go fishing all day? The National Park Service wants anglers to help get rid of exotic brown trout at Lees Ferry on the Colorado River. The agency is giving cash prizes for every fish to try to knock down their numbers. KNAU’s Melissa Sevigny reports, the program is an unusual experiment, designed to meet the goals of the Park Service but also respect the spiritual beliefs of the Zuni Tribe.

A study published in Science last week shows butterfly populations are declining by almost two percent a year in the Western U.S. The authors say that’s driven by climate change. KNAU’s Melissa Sevigny spoke with lead author Matt Forister of the University of Nevada-Reno about the findings, which came from decades of community science data from the North American Butterfly Association.

Endangered fish in the Colorado River face multiple threats. Their survival is linked to the river’s temperature, which is altered both by climate change and by dams. A new study from the U.S. Geological Survey modeled those temperature changes and imagined a future in which water storage is either mostly in Lake Powell or mostly in Lake Mead. KNAU’s Melissa Sevigny spoke with lead author Kimberly Dibble about what those different scenarios mean for native fish.

The U.S. Fish and Wildlife Service has determined the monarch butterfly merits protection under the Endangered Species Act, but it won’t be listed immediately. KNAU’s Melissa Sevigny reports.

Lees Ferry on the Colorado River below Glen Canyon Dam is a world-famous rainbow trout fishery. But in recent years a different nonnative fish, the brown trout, has started to grow in numbers. The brown trout is a predatory fish that gobbles up not only the rainbows but also endangered native species in the Grand Canyon. Now, state and federal wildlife agencies have come up with a plan to reduce their numbers. They’re paying people to go fishing. Starting today, anglers can earn 25 dollars a head for catching and harvesting brown trout. KNAU’s Melissa Sevigny spoke with Ken Hyde, chief of science at Glen Canyon National Recreation Area, about the new incentive program.
