Standing at around 16 inches tall, the native North American rodent has been subject to significant population declines since the early 1900s.

At the Society of Environmental Journalists recent annual conference in Arizona, journalists were taught about the fluctuating numbers of prairie dogs, especially Gunnison’s prairie dogs.

There are many reasons for the decline in the number of prairie dogs, like hunting, but one factor stands out from the rest: the bubonic plague, said Emily Renn, a PhD student at Northern Arizona University’s School of Earth and Sustainability

“Throughout Arizona, Gunnison’s prairie dogs declined over 96% across their range,” Renn said.

However, even though they were petitioned for protection under the U.S. Fish and Wildlife Service, the agency determined that listing the prairie dog under the Endangered Species Act was not justified.

Historically, their range was much broader than today, but there still is hope, said Jim Devos, the Mexican wolf coordinator for the Arizona Game and Fish Department.

“We believe that with some of the conservation measures others are implementing, we anticipate if we can get on top of the plague issue, which is the single greatest challenge today, that we can get back to more robust prairie dogs,” said Devos. Continue reading

New age of safety measures for environmental journalists reporting from the Amazon

This is the 4th in a series of articles about reporting skills by Knight Center students who attended the 2025 Society of Environmental Journalists conference.

Reporters working in or focusing on the Amazon rainforest are forced to take extreme safety measures while doing so. That’s because their coverage threatens industries seeking to exploit  the region’s resources and populations.

At the 2025 conference of the Society of  Environmental Journalists in Tempe, Arizona, this topic was presented by representatives from the nonprofit organization Brazilian Association of Investigative Journalism (Abraji); security manager Valeria Oliveira and project coordinator Reinaldo Chaves.

The panel was hosted in two languages, Portuguese and English, and was part of an effort to answer why journalists in certain regions, like the Amazon, are put into such dangerous positions and how those threats are combated in the field.

Attendees were guided through a presentation on how Abraji funds, trains and mentors reporters investigating environmental crimes in the Amazon, leading to eight successful investigations thus far. Their organization advocates transparency and prioritizes journalists’ ability to have creative freedom to deliver the stories they want, but reinforces that physical security is the most important aspect of their work.

Latin America is the most dangerous place in the world to be an environmental journalist, according to a 2022 study by the international organization Committee to Protect Journalists.. The Amazon region is under particular stress, according to Reuters. In the past decade, over 200 incidents against journalists, such as threats, kidnappings and murders, have been documented.

Knight Center partners team up to report on threats to Great Lakes whitefish

Clara Lincolnhol

Environmental journalism intern Clara Lincolnhol of WKAR radio and environmental journalist Kelly House of Bridge Michigan recently discussed threats to Great Lakes whitefish populations in a public radio broadcast.

Lincolnhol’s internship is underwritten by the Knight Center for Environmental Journalism. House, a Knight Center alum, reports for Bridge Michigan, which partners with the Knight Center as part of the Mott Foundation’s Great Lakes News Collaborative.

Here are the highlights and a transcript of Lincolnhol’s interview with House.

Great Lakes whitefish populations could soon disappear for good

By Clara Lincolnhol

Whitefish are a beloved and iconic Michigan species that have been a staple of the state’s cuisine for centuries.

But their numbers have dwindled drastically recently leaving some worried that the fish will no longer populate the lower Great Lakes.

Kelly House

WKAR’s Clara Lincolnhol spoke with Bridge Michigan reporter Kelly House who recently reported on why the fish population is declining and whitefish’s cultural and economic significance to Michiganders.

On how invasive quagga mussels are threatening whitefish

Scientists have been responding to the threat by trying to find some way to suppress mussel populations in the Great Lakes. They now cover essentially every inch of the lakebed, and the problem is that they’re filter feeders, and they have filtered away the plankton and nutrients that other species in the Great Lakes really rely upon for food. So, these baby whitefish are born. The only thing they eat in their first days of life is phytoplankton, and those plankton are now nowhere to be found, so these babies are essentially starving to death before they ever have the opportunity to grow.

Knight Center alum investigates toxic plume in Ann Arbor

Elinor Epperson

What began as a professional project at Michigan State has turned into a feature project at Michigan Public radio.

Elinor Epperson spent 18 months researching, writing, fact-checking and editing a series of threelongform articles about the Gelman plume, an area of groundwater contamination under Ann Arbor that is several decades old.

The contamination comes from the disposal of industrial wastewater disposal by Gelman Sciences, a one-time medical filter manufacturer.

She also wrote a reporter’s notebook and appeared on the Stateside podcast to provide a more condensed version of the project.

Epperson earned her master’s degree in journalism from the MSU School of Journalism in fall 2024 and still works at the station as an intern.
