Umatilla River Pack

Umatilla River Pack Area of Known Wolf Activity (AKWA) map

Information about wolf/livestock conflict can be found on the Wolf and Livestock Updates and Depredation Investigations pages


February 24, 2015 – Pack summary from 2014 Annual Report:

This pack was first identified in 2013 in the central portion of the Mt Emily Unit. The breeding male is a radio-collared disperser from the Walla Walla Pack. A subadult female was collared (OR28) in 2014 and her data shows the pack using a 257mi2 area comprising 96% public lands. The pair produced at least four pups that survived to the end of the year and was counted as a breeding pair. Two depredation incidents were attributed to this pack in 2014.


February 25, 2014 – From the 2013 Oregon Wolf Conservation and Management Annual Report

First discovered in 2011 in the northern part of the Mt Emily Unit. The pair was counted as a breeding pair for the second year with at least 2 pups. This pack was responsible for 3 confirmed depredations in 2013 with 1 injured sheep and losses of 6 sheep and 1 goat. The breeding male and 2 pups are GPS radio-collared. The collar data shows the pack using a 137 mi2 area with 77% of locations on private lands, 5% public land and 18% tribal land.


October 28, 2013  Young Umatilla River wolves collared after incidental capture

ODFW biologists radio-collared and released two young wolves in a forested area east of Weston, Ore. on Oct. 26. The 55-pound male and a 50-pound female are both young-of-the-year members of the Umatilla River Pack in Umatilla County. Both wolves were incidentally trapped on private land by a licensed trapper who was intending to trap coyotes. They were trapped at the same time in two separate foot-hold traps in close proximity. The trapper followed regulations and immediately reported the situation.   

ODFW biologists were able to quickly respond and safely collar and release the wolves. The two wolves are the third and fourth incidental captures recorded in Oregon. In the two previous incidental captures, the trappers also reported the incidents and the wolves were safely released.

The Umatilla River wolves were fitted with lighter-weight GPS collars ideal for younger wolves. These types of collars collect fewer locations than regular GPS collars, but this pack already has a GPS-collared adult providing location data. The GPS collars on these younger wolves should prove most useful when the wolves disperse.

January 16, 2013 – The ending year-2012 wolf count for the Umatilla River wolves is 4 and Umatilla River are a “breeding pair” for 2012. More information


August 15, 2012 - Pictures taken Aug. 2, 2012 from an ODFW remote camera show that there are at least two wolf pups with the Umatilla River pair. With four individuals in the group, it is now considered a pack.


July 08, 2012 - Umatilla River wolf pair have pups  ODFW surveys also confirmed that the Umatilla River wolf pair have pups. Multiple tracks were found during a summer survey but the exact number of pups is still unknown.

June 20, 2012 - OR14, a wolf using the northern Mt Emily wildlife management unit, was GPS collared by ODFW in the Weston Mountain area north of the Umatilla River on June 20. The gray-colored male wolf weighed 90 pounds and was estimated to be at least 6 years old.

The collared wolf is believed to be responsible for the early May depredations of sheep in the area. The new collar will allow ODFW to better understand his movements and use additional tools to help prevent further depredation. It will also help ODFW communicate with area livestock producers about his whereabouts. OR14 is one of two known adult wolves in the area, and though reproduction is suspected, ODFW has not yet confirmed pups for these wolves.
