OR16 radio-collared in Union County
On Thursday, Nov. 1, 2012 ODFW biologists radio-collared a new wolf (OR16) in the Wenaha Unit of Northeast Oregon (Union County). The 85-pound yearling male was captured north of Elgin in an area that wolves were not previously known to occur. The wolf was captured incidentally by USDA APHIS-Wildlife Services personnel. Each year, ODFW issues an Incidental Take Permit to Wildlife Services which contains provisions to minimize the risk of incidental captures and to protect wolves if incidentally captured. The permit requires close coordination between the two agencies and in this situation the result was a successfully collared wolf released in excellent health. It is unknown at this time if the wolf is part of any of the three known nearby packs (Wenaha, Walla Walla and Umatilla River) or if it represents new wolf activity. Biologists expect that the new GPS collar will soon provide that answer.
October 15, 2012
On Sunday, Oct. 14, 2012 ODFW biologists re-captured OR10 from the Walla Walla Pack. The yearling female wolf weighed 73 lbs and was in excellent condition. She had been previously captured as a pup in October of 2011 and was fitted with a VHF telemetry collar at that time. On this capture her telemetry collar was replaced with a GPS collar which will assist ODFW in gathering much needed location data on this pack.

More wolf depredation
ODFW recently investigated two reported wolf depredations in northeast Oregon. One was confirmed as a wolf and one was determined a “probable wolf”.
Summaries of the investigations are here:
This page defines the criteria for a “probable” wolf determination.

Wolf depredation investigations
ODFW investigated two reported wolf depredations earlier this week—one in Wallowa, one in Union County. The one in Wallowa County was found to be a “probable” wolf depredation while the one in Union County was determined “possible/unknown.”
The summary reports are posted at the link below, which also defines the “probable” and “possible/unknown” determinations.

September 10, 2012 – Pups for Walla Walla pack
ODFW confirmed pups for the Walla Walla Pack on Friday, Sept. 7 when ODFW monitoring cameras documented two black pups travelling with the pack in the upper Walla Walla River drainage. Though reproduction was expected for this pack, it had not been confirmed until Friday. The two radio-collared yearlings (OR10 and OR11) were also documented to still be with the pack. This brings the minimum known size of the Walla Walla pack to 10 wolves (8 adults, 2 pups). It also brings the known number of reproducing wolf packs in NE Oregon to six.
ODFW also recently confirmed additional livestock losses by the Imnaha wolf pack. Details at the links below:
August 30, 2012 – New Upper Minam River wolf pack
A new wolf pack was discovered by ODFW wolf program staff in northeast Oregon on Aug. 25 when a pair of gray-colored adult wolves with five gray pups was observed in the Upper Minam River drainage. ODFW has received irregular wolf reports in the general larger area over the past several years. ODFW had been monitoring wolf activity in the Lower Minam River area since a photo of a black lactating female was taken on June 4. However, these new wolves appear to be unrelated to the lactating female as they were all gray-colored. The home range of these newly discovered wolves is unknown at this time, but represents the fifth litter of pups documented in 2012.

| Umatilla River wolf pups -Oregon Fish and Wildlife- |
August 15, 2012 – Umatilla River wolves
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.
August 9, 2012 – Wenaha Pack pup count
ODFW surveyed the Wenaha pack on Aug 9, 2012 and was able to document seven pups for the pack.
Second wolf in Sled Springs Unit
A second wolf (black) has been confirmed by ODFW in the Sled Springs unit. Surveys will continue in this area and hunter reports may help us learn more about local wolf activity as the fall progresses.
July 03, 2012 – ODFW successfully captured and radio-collared a wolf of the Snake River Pack
ODFW successfully captured and radio-collared a wolf of the Snake River Pack yesterday (Aug. 2, 2012), the first collar for this pack. The 49-lb male pup was in excellent condition and was of a size which could easily handle the lightweight VHF collar. The collar will allow ODFW to monitor the pack in this remote portion of Oregon.
| Snake River Wolf Pack Howling -Video by ODFW- |
July 01, 2012 – Pups and wolf howling video for Snake River pack
The Snake River pack has at least three pups, a July 25, 2012 survey found. Photos taken by remote camera also show at least three adults in the pack.
During this survey in the Summit Ridge area of the Snake River wildlife management unit in Wallowa County, an ODFW employee also captured video footage of one of the pups howling and other members of the pack returning the howl. See the video here. Wolves are highly social animals and howling is a common behavior that helps packs communicate and stay together. Wolf howls can be heard from several miles away.
July 08, 2012 – Imnaha pack pup count
The Imnaha Pack has at least six pups this year, a July 8 survey on US Forest Service lands southeast of Joseph found. There may be more pups but this is the most up-to-date number for the pack. (See photo of pups)
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.
July 19, 2012 – Eagle Cap Wilderness wolf
In late June, ODFW surveyed an area east of the Minam River in the Eagle Cap Wilderness after a remote camera took an image of a lactating female on June 4. At least three adult wolves were confirmed through tracks, scats and howls but no sign of pups was found. A later visit on July 19 found no wolf sign or remote camera photos, so the wolves are believed to have moved out of this immediate area.
July 20, 2012 – Photo captured of wolf in Sled Springs Unit
An image of one wolf was taken by ODFW on July 20, 2012 in the Washboard Ridge area north of Enterprise (Sled Springs Wildlife Management Unit, Wallowa County). Tracks of two wolves were confirmed in this area over the winter and spring, so this may be an area of resident wolf activity.
Summary of genetic results from recently tested wolf samples in NE Oregon.
- A scat collected in the Chesnimnus unit (Devils Run area) on May 2, 2012 was from a wolf that was born in the Wenaha Pack. It is unknown if the wolf is resident in the Chesnimnus unit or was simply passing through the area. It is possible that this is the wolf using the Sled Springs unit (mentioned above).
- OR12 (Wenaha Pack, captured on April 2, 2012) is progeny of the Imnaha pack (OR2 and OR4). OR12 is believed to be the breeding male for the Wenaha Pack and ODFW is currently testing Wenaha pup scats to confirm.
- The pups captured and collared last fall in the Walla Walla Pack (OR10 and OR11) are full siblings and are not closely related to any other Oregon wolves sampled to date.
July 27, 2012 – Depredation by Imnaha Pack
Yesterday evening, ODFW investigated a severely injured calf on a national forestland grazing allotment in the Morgan Butte area (Wallowa County) and has confirmed it as a wolf depredation (Imnaha Pack). The cattle in this forested area had been moved earlier yesterday and the calf was believed to have been attacked during the daytime following that move. This morning the calf is alive but is not expected to survive due to its injuries. An investigation summary will be posted next week.
June 27, 2012 – New wolf activity (lactating female) in Eagle Cap Wilderness
On June 25, ODFW received a trail-cam photograph of a lactating female wolf in the Eagle Cap Wilderness. The image was captured on June 4 on a camera placed by a research biologist as part of another wildlife research project. The wolf was not in an area of known wolf activity (e.g. is not believed to be part of a known wolf pack). The photo clearly shows that reproduction has occurred, but the current location and number of wolves in this area is unknown at this time. ODFW will survey the area to try and gather additional information.

| OR14 -Oregon Fish and Wildlife- |
June 20, 2012 – OR14 GPS collared
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.
June 10, 2012 – Wenaha wolf OR13 collared
ODFW trapped OR-13, a 2-year-old wolf of the Wenaha pack, and fitted her with a GPS radio-collar on June 10. The black female weighed 85 pounds and was captured in the Wenaha Wildlife Management Unit. She was previously caught as a pup in August 2010, but at the time was too small for a radio collar.
May 30, 2012 – Imnaha, Wenaha packs have pups
Biologists observed at least four pups in the Wenaha pack on May 30. In June, reproduction was also confirmed in the Imnaha pack, with a minimum of four pups observed.
