ODFW reports record number of wolves in Oregon

137 wolves counted, up 10 percent in a year

SALEM, Ore. (AP) - A record number of wolves are roaming the forests and fields of Oregon, 20 years after the species returned to the state.

The Oregon Department of Fish and Wildlife said in a report released Monday that the number of known wolves in Oregon at the end of 2018 was 137, a 10 percent increase over the previous year.

There are likely even more wolves because not all individuals or packs are located during the winter count.

Sixteen packs - defined as four or more wolves traveling together in winter - were documented during the count, up from 12 packs in 2017. Wolves were discovered in the central Oregon Cascade Range in late 2018. Several crossed over into California and Idaho.

News release from ODFW:

Oregon’s minimum known wolf count is 137, a 10 percent increase from last year

ODFW releases 2018 Annual Report

SALEM, Ore.—State wildlife biologists counted 137 wolves in Oregon this past winter, a 10 percent increase over last year’s count of 124, according to the Oregon Wolf Conservation and Management 2018 Annual Report released today at www.odfw.com/wolves.

This annual count is based on verified wolf evidence (like visual observations, tracks, and remote camera photographs) and is considered the minimum known wolf count, not an estimate of how many wolves are in Oregon. The actual number of wolves in Oregon is likely higher, as not all individuals or groups of wolves present in the state are located during the winter count.

Sixteen packs were documented during the count, up from 12 packs in 2017. (A pack is defined as four or more wolves traveling together in winter.) Eight other groups of 2-3 wolves were also identified. Fifteen of those packs successfully reproduced and had at least two adults and two pups that survived through the end of 2018, making them “breeding pairs,” a 36 percent increase over last year’s number.

“The state’s wolf population continues to grow and expand its range, now into the central Oregon Cascade Mountains too,” said Roblyn Brown, ODFW Wolf Coordinator.

Highlights from the report:

· Resident wolf numbers and reproduction increased in western Oregon. A second pack (White River Pack) reproduced and was designated a breeding pair for 2018, joining the Rogue Pack. The Indigo group of at least three wolves was also found in the Umpqua National Forest.

· Three collared wolves dispersed to California and one to Idaho.

· Approximately 13% of wolves known at the end of the year in Oregon were monitored via radio collar.

· Biologists documented more than 15,000 wolf location data points by radio collar or other methods including aerial, track and howling surveys. 53% of these locations were on public land, 40% on private and 7% on tribal.

· The breeding female of Oregon’s oldest known reproducing pack, the Wenaha Pack, disappeared and no reproduction was documented for the pack in 2018. The female wolf was at least 10 years old, which is old for a wolf living in the wild, and she appeared in poor body condition in summer trail camera photos.

Unlawful take of wolves decreases

Two wolves were found killed unlawfully in 2018 (down from four in 2017). A juvenile wolf believed to be from the Grouse Flats Pack (a pack that uses Oregon but is counted as a Washington state pack because it dens there) was shot. The radio-collared breeding female of the Mt Emily Pack was shot on the Confederated Tribes of the Umatilla Indian Reservation. Oregon State Police and CTUIR law enforcement continue to investigate these incidents and are actively seeking more information. Rewards ranging from $2,500 to $15,000 have been offered for information leading to a conviction in these and previous cases.

Livestock depredation increases

Confirmed depredation incidents by wolves increased 65 percent from last year, with 28 confirmed incidents (up from 17 last year). A total of 17 calves, one llama and two livestock guardian dogs were lost to wolves and an additional 13 calves were injured. Three wolf packs were responsible for the majority of depredations (Rogue - 11, Pine Creek - 6 and Chesnimnus - 5).  While known wolf numbers have increased considerably over the last nine years, depredations and livestock losses have not increased at the same rate.

In all phases of wolf management, Oregon’s Wolf Plan mandates that non-lethal efforts are undertaken before lethal removal is considered. In 2018, those measures included removing attractants, hazing, electrified fladry, fence maintenance, radio-activated guard boxes, increased human presence, range riders and other husbandry practices.

ODFW, U.S. Fish and Wildlife Service and USDA Wildlife Services continue to support livestock producers in their non-lethal efforts with technical advice, supplies and assistance with implementation.

“As the wolf population has expanded into new areas in Oregon, livestock producers have adjusted the way they do business to remove bone piles and incorporate non-lethal measures that can reduce the vulnerability of their livestock to depredation by wolves and other predators,” said Roblyn Brown, ODFW Wolf Coordinator. “We extend our thanks and appreciation for their efforts.”

The Oregon Department of Agriculture’s Wolf Depredation Compensation and Financial Assistance Grant Program also awarded $160,890 in grant funds to compensate livestock producers for losses and to fund preventive non-lethal measures.

ODFW staff will present an overview of the draft Oregon Wolf Conservation and Management 2018 Annual Report to the Fish and Wildlife Commission at their Friday, April 19 meeting in St Helens. The presentation will be during the Director’s Report, and no public testimony is taken during this portion of the meeting.
