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.
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.
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.
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)
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.
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.
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.
(6/27/2012) 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.
(6/20/2012) 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.
(6/10/2012) 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.
(5/30/2012) 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.
