Something is happening to Wisconsin’s wildlife. It is happening in the dark, in the timber cuts of the Chequamegon-Nicolet, along the shores of the Winnebago, in the sky above the Mississippi flyway. Animals protected by federal law are being shot, trapped, and trafficked. And for the first time in decades, almost no one with the authority to stop it is watching.

This is not speculation. It is documented — in rehabilitation records, in peer-reviewed research, in federal court filings, in the testimony of conservation officers who are watching it happen. The poaching crisis gripping Wisconsin right now is real, it is worsening, and it is unfolding at precisely the moment when the systems built to detect and stop it have been gutted.

Great Lakes Wildlife Alliance has spent the past year building a scientific and legal record of this crisis. This report summarizes what we know — and what we are doing about it.

The Shootings Wisconsin Couldn’t See Coming

It started with the birds. In early 2021, wildlife rehabilitators across Wisconsin began noticing something troubling: more and more non-hunted birds were coming in shot. Bald eagles. Red-tailed hawks. Trumpeter swans. Turkey vultures. Loons. The species arriving at rehabilitation centers with bullet wounds, embedded shot, and lead pellets in their beaks were not game birds. Every single one of them was protected by federal law.

The rehabilitators reached out to Wisconsin’s Green Fire, the state’s premier science-based conservation organization, for help making sense of what they were seeing. What followed was the most comprehensive investigation of illegal bird killing in Wisconsin’s history.

Phase 2 of that research is now underway, building a standardized database with the Wisconsin DNR to track illegal bird deaths statewide. But here is the critical point Kerry Beheler and her colleagues have made publicly and on the record: the 70 birds they documented are almost certainly a fraction of what actually happened. The data came from four rehabilitation organizations. Dozens more operate across Wisconsin. The real number is unknown — and getting harder to know every year.

The Wolves Being Killed in Plain Sight

If the bird poaching crisis is happening largely in the dark, Wisconsin’s wolf poaching crisis has been documented in peer-reviewed science and federal court records for years — and it is getting worse.

University of Wisconsin-Madison researchers Adrian Treves, Francisco Santiago-Avila, and Karann Putrevu have spent years building the scientific case that poaching of wolves does not occur independently of policy. It is driven by it. Every time federal protections for wolves are weakened or removed, illegal killing surges. The mechanism is not complicated: when political leaders signal that wolves are not worth protecting, people who are hostile to wolves treat that as permission.

Now, in 2026, those federal protections are gone. HR 845 has passed the U.S. House and would strip wolves of ESA protection permanently — eliminating the five-year post-delisting monitoring requirement, the relisting pathway, and judicial review all at once. Wisconsin wolves are being planned for by a Wolf Advisory Committee that is designing hunting zones, quotas, and season structures for a species that is currently, as of the date of this report, still federally protected.

And since the petition GLWA filed in June 2025, at least four Wisconsin wolves have been documented as illegally killed in connection with wildlife killing contests. Four that we know about. In a state where cryptic poaching is the norm, not the exception.

The Contest Connection

Wildlife killing contests — organized events in which participants compete for prizes and cash for the most animals killed — remain legal in Wisconsin. They are, by design, an incentive structure for killing. And they are correlated, in documented cases, with the illegal killing of protected species. When the culture of a contest normalizes mass killing of wildlife, the line between legal and illegal prey becomes less important to some participants than the act of killing itself.

GLWA has been fighting to end wildlife killing contests in Wisconsin for years. The wolf poaching tied to these events is not an accident. It is a predictable outcome of a regulatory environment that treats wildlife killing as sport and protected species as an inconvenience.

The Sturgeon No One Is Guarding

Lake Winnebago holds something extraordinary and almost entirely unappreciated: the largest wild lake sturgeon population on Earth. These are animals that can live 150 years, that have survived every mass extinction event for 136 million years, that are now critically endangered globally. And Wisconsin is sitting on the world’s largest wild population of them.

It is also, as of 2026, the world’s largest unguarded caviar source.

Wisconsin’s own DNR has acknowledged this openly. “We believe there is an international black market that trades in Lake Sturgeon roe generally,” the DNR has stated publicly. The agency values lake sturgeon caviar at approximately $100 per ounce. A mature female can carry up to 20 pounds of eggs. And domestic sturgeon caviar has been documented selling for up to $880 per pound on the black market — some of it falsely labeled as Russian roe as Caspian Sea stocks have collapsed.

The enforcement infrastructure that once deterred this trafficking — the USFWS Office of Law Enforcement, which investigates interstate and international wildlife crime — has been gutted. The USFWS Madison office was designated for closure by DOGE. The federal agents who would investigate caviar trafficking networks are gone. What remains is a state DNR that documents five to nine violations per spearing season and a politically active congressional delegation that introduced legislation specifically designed to prevent sturgeon from ever receiving federal protection — even after USFWS already decided not to list them.

That legislation, the SPEAR Act, introduced by Reps. Wied, Grothman, and Tiffany in February 2025, was designed to permanently exempt Wisconsin lake sturgeon from any future ESA listing. The sponsors introduced it after the no-listing determination had already been made — as a preemptive block on any future science that might support protection. It is a legislative document that says, in plain terms: no matter what the science shows, Wisconsin sturgeon will never be protected.

The Monitoring System That No Longer Exists

Here is the question that underlies everything else in this report: how do we know the scale of what is happening? And the honest answer is: we don’t. Not anymore.

The systems built over decades to track wildlife populations, detect illegal killing, and monitor species health have been systematically dismantled since February 2025. What has been lost is not a collection of marginal programs. It is the scientific infrastructure that made responsible wildlife management in this state possible.

The result of all of this is not simply that we have fewer people watching. It is that we have lost the capacity to know what is happening. Poaching that was already 95% undetected nationally — per the 2025 Boone & Crockett Poach and Pay research — is now even less detectable, because the monitoring infrastructure that might catch population crashes before they become irreversible has been shut down.

The God Squad and the End of the Federal Safety Net

On March 31, 2026 — eleven days ago — something happened that most Wisconsinites don’t know about, but that changes the legal landscape for every species in this state.

The Endangered Species Committee — the “God Squad,” a body created as a last-resort mechanism to be used perhaps once a generation — voted unanimously to exempt all Gulf of Mexico oil and gas activities from ESA Section 7 requirements. It was the first time in the ESA’s history that the national security exemption had been invoked. And President Trump’s Day One executive order directs this committee to convene at least four times a year to issue exemptions.

The ESA was not designed for a world in which industries can claim national security and bypass species protection on a quarterly basis. It was designed as a hard floor — a legal bottom below which no species could fall. That floor is gone now. For every species in Wisconsin that was relying on federal protection as a backstop, Wisconsin state listing is no longer a supplementary layer. It is the only layer.

What GLWA Has Done — and What the State Has Refused to Do

GLWA has not watched this crisis from the sidelines. Since June 2025, we have done everything Wisconsin law requires — and more.

The wolf petition is not GLWA’s only legal action in preparation. We are preparing a wave of additional petitions for Wisconsin species whose state conservation status is demonstrably inadequate given the collapse of federal protections. The snowshoe hare — absent from 78% of its historical Wisconsin locations and still hunted. The American woodcock — declined 39% since 1968, with the Bird Banding Lab that tracks it facing closure. The golden-winged warbler — a quarter of the world’s population nests in Wisconsin, and the state doesn’t have it listed at all. The Connecticut warbler — three breeding pairs documented in the entire state. Bats. Sturgeon. Migratory birds by the species.

These petitions are coming. The legal record being built right now is the foundation for litigation if the WDNR continues to refuse to act.
