Utah moving beavers to improve habitat, streams
he Associated Press
CEDAR CITY -- Utah biologists are relocating beavers from private lands to improve wildlife habitat, regulate stream flows and protect the rodent.
The Salt Lake Tribune reports nine beavers are being released into a stream in southern Utah's Dixie National Forest. They are the first group of beavers moved under a state management plan for the American beaver.
Division of Wildlife Resources biologist Dustin Schiable says the state developed the management plan as an alternative to killing the animals. Prior to the plan's adoption in 2010, landowners could obtain permits to trap and kill beavers.
Grand Canyon Trust biologist Jeremy Christensen says transplanted beavers build dams on streams where runoff is a problem. Beaver ponds can also spur the development of meadows and other habitat for a variety of species.

Beavers have new forest digs in first test of new Utah plan
Wildlife » Revised management plan lets rodents be relocated.

Cedar City • The first relocation of beavers under a revised state management plan went swimmingly, according to state wildlife officials.
Since Friday, nine of the rodents have been released in a southern Utah stream in the Dixie National Forest under terms of a plan that allows biologists to trap and transplant beavers to sites where they can help restore watershed and landscapes.

This relocation was set in motion by Merril Evans, who owns irrigated pasture land in Panguitch where six of the beavers were trapped. Evans said he called the Division of Wildlife Resources (DWR) and asked what he could do when he noticed beavers were cutting down trees on his property. He gave permission for the animals to be trapped.
"They were really great guys," he said of a biologist and a volunteer from the Grand Canyon Trust. They not only trapped the rodents but protected still standing trees with wire fencing to prevent future problems from other beavers.
According to Dustin Schiable, a biologist in the DWR Cedar City office, the revised management plan has been in the works since 2009, and involved a coalition interested in saving the beavers, whose diminished numbers are attributed to human activity such as trapping. Before the plan was adopted in 2010, landowners obtained permits from the DWR and usually killed the beavers.
Schiable said beavers are considered by some private landowners to be a "nuisance species" because they fell trees and block water channels.
The new management plan reflects the current thinking that beavers can improve landscapes. Jeremy Christensen, a biologist with the Grand Canyon Trust, which played an active role in revising the management plan, said the transplant should provide a prime example of how relocation can be used as a management tool.
Beaver dams are a natural way to regulate stream flows, especially in areas of heavy runoff where the animals have been eradicated. The dams create ponds that slowly let out water as needed. Once a pond is created, it can spur development of meadows and habitat for other species, including the boreal toad, listed as a sensitive species in Utah that survives best in conditions created by beavers, Christensen said."They repair waterways," he said. Beaver dams also encourage growth of willows, cottonwood trees and aspen, a beaver delicacy.

Coyotes and deer focus of new study
Southern Utah study involves DWR, volunteers and two universities There's no question that coyotes kill mule deer, especially fawns.
But just how many fawns do coyotes kill? And how does the killing affect the number of mule deer in Utah?What about efforts to control coyotes? How effective are those efforts? And how do those efforts help deer in the state?
Biologists with the Division of Wildlife Resources want to know. In cooperation with Brigham Young University and Utah State University, they're launching a study to find out.
The study begins in June on Monroe Mountain in south-central Utah. If you'd like to help with the study, you can—biologists and university researchers need volunteers
.
To learn more about the project and to sign up to help, plan on attending a meeting on May 17 in the auditorium at the Sixth District Courthouse in Richfield.
The May 17 meeting starts at 7 p.m. The courthouse is at 845 E. 300 N.

Studying fawns and coyotes
Here's how the study this summer will work:
- Doe mule deer will be captured and fitted with radio collars and a vaginal-implant transmitter (VIT) that will be inserted in such a way that it will exit the doe when she gives birth to a fawn.
When the VIT is expelled, it will begin transmitting, alerting biologists that a fawn has been born and giving them the exact location where the fawn is.
Immediately, biologists and a volunteer search crew will travel to the area to find the fawn and fit it with an expandable radio collar.
Once the fawns are fitted with the expandable collars, biologists will monitor them for about six months to see how many fawns survive the first critical months of their lives.
Deer fawns aren't the only animals that will have radio collars placed on their necks—coyotes will too.
- After collaring the coyotes, biologists and researchers will monitor them to assess the coyotes' location in relation to deer fawns in the area.
- As part of the study, personnel with USDA-Wildlife Services will also conduct high-intensity coyote control on half of the Monroe management unit. On the other half, no coyote control will happen. Comparing how fawns did on areas where coyotes were controlled versus how they did on areas with no control will help biologists and researchers learn more about the effect coyote control has on the number of fawns that survive.
- Placing collars on coyotes will also allow researchers to estimate the size of the coyote population, how the coyotes use the habitat, the coyotes' activity patterns and the effect coyote control work has on the coyote population.
