Thirteen percent of the white-tailed deer in the town of Libby could be infected with chronic wasting disease (CWD), the highest prevalence rate in the state. Montana Fish, Wildlife and Parks said this fall’s sampling efforts determined prevalence is almost three times the agency’s threshold for more aggressive management actions.

Montana wildlife officials announced Wednesday that a white-tailed deer in southwest Montana has, for the first time, tested positive for chronic wasting disease. The deer population in the Ruby Valley is dense, which could fuel transmission.

Montana wildlife managers say 91 cases of chronic wasting disease (CWD) have been found statewide so far this year. The Libby area accounts for nearly half of those detections and that number is expected to grow with results still rolling in from this year’s big game season.

A moose in Montana has tested positive for chronic wasting disease (CWD) for the first time. The finding expands the area wildlife managers believed the disease to exist.

The moose was killed north of Troy, just a half of a mile outside of the Libby CWD management zone, which spans a 10-mile radius around Libby. Thirty white-tailed deer have tested positive for CWD within the management zone since the disease was discovered this spring.

Both deer and elk rifle hunting seasons opened across the state Saturday and hunters hiked into the woods at the crack of dawn in the hopes of coming out with some fresh meat to stock their freezers. That ritual was a little different this year for hunters in the Libby area, where chronic wasting disease (CWD) has been detected in white-tailed deer.

The number of white-tailed deer infected with Chronic Wasting Disease continues to climb in Libby. Eighteen white-tailed deer have now tested positive since the count started this spring.

Hunter-harvested deer are expected to shed more light on the spread of the disease when general rifle season starts later this month.

Montana officials are expanding restrictions on the transport of big game animals to prevent the spread of a fatal disease.

State game managers say another white-tailed deer is likely positive for Chronic Wasting Disease in Libby. If confirmed, this would be the tenth deer to test positive since the spring.

It’s been two years since Chronic Wasting Disease (CWD) was detected in Montana’s deer herds, and in May the disease popped up in the northwest corner of the state in Libby. Montana Fish, Wildlife and Parks (FWP) has a plan to manage the fatal disease based on its prevalence, a strategy born from more than 20 years of trial and error across the country.

The Montana Department of Fish, Wildlife and Parks is wrapping up a series of public meetings on Chronic Wasting Disease, or CWD. This week, the agency explained its initial management strategy for the Libby area where six white-tailed deer have tested positive for the fatal disease.

CWD was detected in Libby this spring. It’s the first case of the disease showing up in a wild herd in western Montana.
