Oklahoma Just Released a Captive Whitetail Deer into the Wild...On Purpose

For the first time ever, a captive-raised deer has been released into the wild whitetail population to slow the spread of Chronic Wasting Disease (CWD).

The historic move is part of a programinstituted by the Oklahoma state legislaturein 2024. The Chronic Wasting Disease Genetic Improvement Program is intended to bolster wild deer genetics by releasing captive deer that have a resistance—though not an immunity—to the always-fatal disease.

But opponents say that meaningfully improving wild herd genetics would require releasing hundreds of thousands of deer. What’s more, those releases could have the opposite effect: captive deer are not tested for CWD prior to release and may end up spreading the disease to new areas or introducing novel strains.

“That's not how you mitigate the disease,” said Catherine Appling-Pooler, the director of policy for the National Deer Association. “People have grabbed onto this research because it offers hope against a disease that is 100 percent fatal. But hope should not get in the way of science. We need to make sure this can be repeated, that it’s peer reviewed, and that it’s accepted by more than just one scientist.”

The concept of fighting CWD by improving the genetics in the wild herd has been pioneered by a Texas biologist named Dr. Chris Seabury. However, while farmers did something similar to eliminate scrapie in sheep herds, the technique has never been proven effective—or even tested—in wild populations.

State veterinarian Dr. Rod Hall confirmed in an email to MeatEater that a captive-raised deer was released in Wagoner County, Oklahoma. The animal met the genetic requirements of the state’s new genetic improvement program but was not tested for CWD. Appling-Pooler tells MeatEater as many as five more deer could be released on low-fence properties in Oklahoma before the April 15, 2026, deadline.

The release of this deer was not approved by wildlife professionals at the Oklahoma Department of Wildlife Conservation (ODWC). Instead, as per the language in the 2024 bill, the Oklahoma Department of Agriculture, Food, and Forestry (ODAFF) okayed the release according to theirone-page listof requirements.

As MeatEaterreported at the time, wildlife officials and hunting groups were shocked when the Genetic Improvement Program sailed through the Sooner State legislature. But not only did the bill pass on a nearly unanimous basis, it also left the ODWC with little input on whether and how these captive deer should be released into the wild. The bill said the wildlife agency “may” charge a one-time permit fee, but it gave the ODAFF the authority to promulgate rules for the program. It was unclear whether the ODWC also had the ability to impose permit requirements, and the agency never went through the rulemaking process.

Frustrated by this perceived lack of action, Oklahoma Representative Nick Archer introducedHouse Bill 3270during this legislative session. This bill entirely removes the ODWC from the decision-making process and grants permitting authority solely to the Department of Agriculture (ODAFF).

At the same time, the ODAFF is moving forward with deer releases.

“It's completely removing wildlife professionals from the program and from the conversation and from, most importantly, the decision making. And that's what NDA and others oppose. Wildlife professionals should be involved in decisions that directly impact wildlife in the state,” Appling-Pooler said. “It's not just about CWD. It's an overreach by the legislature on the department's authority to do their job.”

The Oklahoma Wildlife Conservation Commission has not historically endorsed or opposed specific pieces of legislation, but they have come out against HB 3270.

“HB 3270 would authorize a practice that has never been implemented in Oklahoma and has not been adopted by any state wildlife agency as a management tool,” the commission wrote in a position statement. “The Commission finds that such action warrants comprehensive scientific review and careful consideration of all potential unintended consequences before any implementation.”

One of those unintended consequences is the potential exclusion of all Oklahoma deer from the Boone & Crockett and Pope & Young record books. These organizations have alwaysexcluded genetically manipulated animals from their records, and releasing captive deer into Oklahoma’s wild herd might disqualify the entire herd.

The Oklahoma Department of Wildlife Commission held a meeting April 6, to which they invited several wildlife biologists to speak to this issue. (It’s worth checking out in its entiretyhere). One of them,Dr. Jennifer Malmbergof the National Wildlife Research Center, laid out a model showing how many deer would need to be released in order to improve the genetics of the wild herd.

Releasing a number of deer equal to 1% of the wild population would have almost no effect on the wild herd. There are an estimated 750,000 deer in Oklahoma, which means even if 7,500 CWD-resistant deer were released every year for 10 years, it would have a negligible effect on wild deer. Releasing 75,000 deer each year over 10 years would have a greater effect, but it still wouldn’t make the entire herd resistant (which, again, doesn’t make them immune).

What’s more, this model assumes a best-case scenario. It assumes captive deer will breed and survive at the same rate as wild deer (which is unlikely) and that there will be no landscape fragmentation that will affect gene flow (roads, cities, etc.).

While releasing a realistic number of captive deer would create very little benefit, it could result in significant cost. Dr. Malmberg noted it could spread CWD into new areas of the state, but it would also dramatically alter the behavior of deer in the Sooner State.

“It can alter deer density and resource selection. It’s very likely that deer that are released from captivity into the wild will use human resources, and we know that that results in more CWD,” she told the commission.

The Oklahoma State House voted to remove the ODWC from the whitetail release program on a 68-21 vote. This might seem one-sided, but it represents a significant uptick in opposition from 2024, when only three legislators voted against the program. HB 3270 now heads to the Senate, where it sits before the Agriculture and Wildlife Committee.

Appling-Pooler says despite the large margin of “Yes” votes in the House, the Senate might present more difficulties for this legislation.

“I am more optimistic than I usually am on this issue,” she said. “I have heard more opposition from legislators. They've been hearing from their constituents, and they are listening to their constituents, which is always really appreciated. I'm encouraged by the constituent engagement we've had.”

If you’d like to be one of those constituents—which include residents of neighboring states who might have an opinion on pen-raised deer mingling with wild animals—you can contact state legislatorshere.
