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 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
