FWP has extended the general hunting season for white-tailed deer in an area of southwestern Montana, effective immediately, in response to a recent increase in chronic wasting disease detections in the greater Bozeman area.
FWP biologists documented a notable increase in CWD cases this year, with nine detections during the most recent hunting season, compared with zero to two cases annually from 2020 to 2024. Fourteen total cases have now been confirmed in the area. White-tailed deer populations remain robust, with localized urban densities exceeding 60 deer per square mile in some locations.
The primary purpose of the hunting season extension is to reduce white-tailed deer densities in the area to slow the spread and impact of CWD. Hunters also play a key role in helping wildlife managers gather data on CWD prevalence by submitting test samples from harvested animals.
The extended season runs through Feb. 15, 2026, in all of Hunting District 309 and portions of HDs 301, 304, 311 and 312, primarily along the Gallatin River corridor where white-tailed deer are most concentrated.

During this extension, hunters may harvest either-sex white-tailed deer using a General Deer License and antlerless deer with applicable Region 3 antlerless Deer B licenses. The 003-00 and 398-00 Antlerless White-tailed Deer B licenses, which are valid for the extended hunt, are currently available for purchase.
Hunters are reminded that HD 309 is a weapons restriction area, and all applicable weapons restrictions remain in effect during the extended season. Other rules applicable during the general season still apply during this season extension.
Public land opportunities in the hunt area are limited, and there are no Block Management areas enrolled at this time. Hunters are required to obtain landowner permission before hunting.
Hunters participating in the extended season are strongly encouraged to submit samples for CWD testing to help FWP better estimate disease prevalence. Hunters can find resources on how to collect and submit samples here. Hunters who collect the samples themselves can bring them to FWP’s Bozeman office, 1400 S. 19th Ave., during normal business hours from Monday through Friday, 8 a.m. to 5 p.m.
Beginning Jan. 3, FWP technicians will also be available Monday through Friday from 8 a.m. to noon at the Bozeman FWP office to assist hunters with sampling. At that time, hunters can bring the unfrozen head from their harvested white-tailed deer with a few inches of neck attached for assistance.
