By 2014, OR-7 had settled in the Rogue River watershed in the southern Cascade Range east of Medford, Oregon, with a mate. It is not known when the two wolves met, but DNA tests of fecal samples showed that she is related to wolves in two of the eight packs in northeastern Oregon. In early 2015, officials designated the two adult wolves and their offspring as the Rogue Pack, the first wolf pack in western Oregon and the state's ninth overall since wolves returned to Oregon from Idaho in the 1990s. The batteries in OR-7's tracking collar expired in October 2015, and monitoring the pack since then has depended on trail cameras and live sightings. Meanwhile, other wolves have migrated into the mountainous cross-border region, and relatives of OR–7 have formed two packs in northern California.

OR-7 was not observed at the 2020 winter count of wolves in Oregon, and as of April 2020 is presumed to have died.

Background

Wolves in the United States were protected under the federal Endangered Species Act in 1978 as they were in danger of going extinct and needed protection to aid their recovery. Wolves were reintroduced to Idaho and expanded their range into the northern Rocky Mountains and Pacific Northwest. When wolves began swimming the Snake River from Idaho to Oregon in the 1990s, the Oregon Department of Fish and Wildlife (ODFW) started live-trapping the growing wolf population in Oregon and fitting them with GPS tracking collars that provide daily satellite position reports. State biologists gave a sequential designation to each wolf with a collar. The vast majority remain clustered in their historic range in the northeast corner of the state, where the forests between the high mountains and populated areas are full of elk and deer. In 2010, state biologists noticed wolves in the Cascade Range but were unable to determine if they were single dispersing animals wandering through or were starting to occupy the area. Individual wolves will roam, searching for a mate and new territory. In February 2011, the Oregon Department of Fish and Wildlife attached radio collars to several wolves in the Imnaha Pack in northeastern Oregon to allow study of their migration. The pack was Oregon's first since wolves returned to the state. The wolves were numbered; one of them, a year-old male from the pack's second litter, was given the code OR-7 as the seventh wolf to be collared.
