The Sheridan Region welcomed two new personnel to the region this summer.
Sheridan Region fisheries supervisor
Stephen Siddons began duties as the Sheridan Region fisheries supervisor this summer, overseeing fish management and conservation throughout most of northeast Wyoming.
Originally from Tennessee, Siddons received a bachelor’s degree in wildlife and fisheries science from the University of Tennessee in 2011 and a master’s degree in applied ecology from the University of Nebraska in 2015.
Siddons was hired by the Wyoming Game and Fish Department in 2017 as a biologist with the Statewide Aquatic Assessment Crew, where he mostly focused on native fish management and conservation throughout Wyoming.
In 2023, he took the position of regional fisheries biologist with the Laramie Region before being promoted to the Sheridan Region fisheries supervisor position in August 2025.
“We're lucky in the Sheridan Region that we have had a great fish management team here over the past twenty years,” said Siddons. “The Sheridan Region has a unique blend of prairie river systems, large reservoirs, and high elevation trout fisheries, including native cutthroat trout, that fits very well with my experience throughout my career. I really hope to leverage my passion and experience to continue pushing the bar for sportfish work and native species conservation in the region. I don't anticipate a lot of large changes, but I do hope we can focus on a few issues.”
Siddons said some areas he intends to prioritize are management and restoration of native Yellowstone cutthroat trout in the northern Bighorns, supporting ongoing efforts to prevent the spread of aquatic invasive species in northeast Wyoming, improving angling opportunities at Lake DeSmet and expanding outreach to include anglers in decision-making opportunities around the region.
“I have a great passion for the work we do - providing high quality and diverse sport fisheries, conserving native species, and protecting and improving aquatic habitats,” said Siddons. “My wife, son, and I are happy to be a part of the community now and we look forward to getting to know people and being involved. I encourage anglers to reach out to me to share any thoughts or challenges they are seeing around the region.”
Buffalo game warden
Zane Stewart transferred to the Buffalo game warden district in September 2025.
Stewart grew up in Colorado and earned bachelor’s degrees from the University of Wyoming in wildlife and fisheries biology and management, as well as environment and natural resources in May 2019.
“I grew up spending a lot of time outdoors with my family hunting and fishing,” said Stewart.
During his studies and after graduation, Stewart worked on ranches in Colorado and Wyoming and multiple jobs for Colorado Parks and Wildlife, including as a chronic wasting disease technician, a wildlife technician overseeing state wildlife habitat areas and in a hunter outreach position.
He was eventually drawn to the enforcement side of wildlife management as a result of early, positive experiences with game wardens.
In December 2023, he was hired by the Wyoming Game and Fish Department and attended the Wyoming Law Enforcement Academy, graduating in April 2024. He served as a game warden in Casper before transferring to the West Rawlins game warden district in January 2025.
Stewart is an avid horseman and looks forward to exploring the Buffalo area.
“I always knew I wanted to end up in this area of the state,” said Stewart. “It is great having a district where you are minutes from either being in the mountains or being on the plains. There are so many recreational opportunities here. I am looking forward to exploring more of the district and meeting local residents and landowners in the coming months.”
