Colorado’s Wolf Reintroduction Program Is in Hassle: 14 of 25 Transplanted Wolves Are Now Useless

Greater than half the wolves Colorado bodily moved into the state are gone, and no new releases are deliberate for 2026.

The numbers usually are not good. Colorado Parks and Wildlife confirmed on March 13 that grey wolf 2310, the maternal feminine of the King Mountain Pack, died after the company picked up a mortality sign on March 11 in northwest Colorado. That brings the whole to 14 useless wolves out of the 25 that CPW bodily translocated into the state for the reason that program started in December 2023. That may be a 44% survival fee.

CPW stated it’s main the mortality investigation in session with the U.S. Fish and Wildlife Service. No reason for loss of life has been launched. A ultimate dedication is not going to come till the necropsy and investigation are full.

The King Mountain Pack Has Taken Two Hits This 12 months

Wolf 2310 was one of many authentic 10 animals Colorado introduced in from Oregon through the first launch wave in December 2023. She was additionally a key member of the King Mountain Pack, one of many few packs within the state that has efficiently reproduced. The pack produced three pups in 2025.

That is the second vital loss for the King Mountain Pack in only a few months. In January, a breeding male from the identical pack died whereas CPW biologists had been making an attempt to suit it with a brand new monitoring collar. Shedding two breeding adults from a pack that was one of many program’s vibrant spots is a critical setback.

A Program That Was Already Struggling

Colorado voters narrowly accepted wolf reintroduction by Proposition 114 again in November 2020, which required the state to start releases west of the Continental Divide by the tip of 2023. CPW adopted by, bringing in 10 wolves from Oregon that December. A second wave of 15 wolves got here from British Columbia in early 2025.

The unique plan referred to as for shifting 30 to 50 wolves into Colorado over a three- to five-year interval. However in January 2026, CPW introduced it could not conduct one other launch this yr. The company cited federal strain associated to the British Columbia supply inhabitants, in addition to the continued mortality drawback.

CPW Wolf Program Supervisor Eric Odell put it plainly in that January replace. If mortality stays excessive, he stated, the chance of failing to determine a self-sustaining wolf inhabitants in Colorado will increase. That’s now wanting like an actual chance relatively than a distant concern.

The 44% Determine Has an Asterisk

It’s price noting that the 44% survival fee applies solely to the wolves CPW bodily moved into the state. It doesn’t depend wolves born in Colorado by replica, and the whole variety of wolves at present on the panorama might be larger due to these pups. The King Mountain Pack’s three 2025 pups, for instance, usually are not included within the 25-wolf depend.

Nonetheless, the survival fee amongst transplanted animals is the clearest scorecard for whether or not the reintroduction effort itself is working. Proper now, that scorecard just isn’t wanting good.

What This Means for Hunters and Ranchers

Colorado hunters have watched this program carefully for the reason that starting. Wolves prey on elk, deer, and livestock, and their presence modifications how recreation animals transfer and the place they maintain. In areas close to identified wolf territory, hunters and outfitters have already reported modifications in elk conduct, with animals shifting out of conventional drainages and into thicker nation.

Ranchers in northwest Colorado have additionally handled confirmed livestock depredations, although CPW’s compensation program exists to cowl documented losses. The larger concern for a lot of has at all times been whether or not this system would attain the dimensions initially envisioned. A self-sustaining inhabitants of fifty or extra wolves would have very completely different ecological and behavioral results than a struggling group of 11 scattered survivors.

For now, this system is in a holding sample. No new wolves are coming in 2026. The animals already on the bottom will both maintain on or they won’t. CPW is watching, investigating, and hoping the packs that stay can stabilize on their very own.
