How the Public Trust Doctrine Built the Uniquely American Idea of Publicly Owned Wildlife and Wildlife Management

In this episode, AJ and Gabby explore the origins of the Public Trust Doctrine with Leon Szeptycki and examine how a series of legal and political turning points helped shape wildlife conservation in the United States. From Roman law and medieval England to landmark Supreme Court cases and the conservation movement of the Progressive Era, they trace how the idea of wildlife as a shared public resource became embedded in American law and culture.

AJ and Gabby discuss how Europe’s long history of private hunting rights tied wildlife access to land ownership, and why the United States ultimately took a different path—one in which wildlife is collectively owned by the people rather than by landowners or the state itself.

They break down several pivotal Supreme Court cases, including Martin v. Waddell, Illinois Central Railroad v. Illinois, Geer v. Connecticut, and Hughes v. Oklahoma, explaining how each helped define the relationship between public ownership, state authority, and wildlife management. Along the way, they explore how these decisions laid the groundwork for modern fish and wildlife agencies and the broader North American Model of Conservation.

This episode also examines modern tensions surrounding public lands, private landowner tag allocations, and the ongoing debate over who truly benefits from wildlife management today. Throughout the episode, AJ and Gabby argue that understanding the civic and legal foundations of conservation is essential for hunters hoping to engage meaningfully in the future of public lands, wildlife policy, and access in North America.

GPS tracking reveals American woodcock re-nesting movements across the Atlantic Flyway

In this episode, AJ and Gabby talk with Colby Slezak, a recent PhD graduate from the University of Rhode Island, about a surprising breakthrough in American woodcock ecology: evidence that female woodcock can be itinerant breeders.

Colby explains how new GPS tracking technology, combined with on-the-ground nest checks through the Eastern Woodcock Migration Research Cooperative, helped confirm a behavior that had long been suspected but rarely documented. When nests fail, some female woodcock will travel long distances and attempt to nest again elsewhere, sometimes multiple times in a single spring.

We unpack why woodcock have such an extended breeding season, what low nest success looks like on the ground, and how constraints like GPS tag size and battery life shape what researchers can learn about breeding ecology. Colby also reflects on the moment he and his colleagues realized their data supported this long-standing theory, an unexpected discovery that reshaped how researchers understand woodcock breeding behavior.

The conversation then shifts to Colby’s brief time with the U.S. Fish and Wildlife Service and what federal workforce reductions and buyouts may mean for conservation capacity, long-term partnerships, and the institutional knowledge behind migratory bird research.

In the Project Upland Podcast episode “The Birds Aren’t Alright,” hosts Gabby Zaldumbide and A.J. DeRosa speak with Dr. Michael Brasher, senior waterfowl scientist at Ducks Unlimited and co-chair of the State of the Birds Report Science Committee, to uncover what the latest data reveal about bird population trends—and what is at stake if federal funding for avian research disappears.

Bird species have been monitored for more than a century, but if federal funding for avian research is lost, what else will vanish with it? The conversation traces the roots of modern bird monitoring back to the first Christmas Bird Count in 1900 and explains how decades of citizen science, state surveys, and federal efforts now feed into one of the most important bird conservation reports of our time. Dr. Brasher shares how long-term data collection reveals population changes in ducks, seabirds, upland game birds, and more, underscoring that the greatest driver of decline is widespread habitat loss.

The discussion highlights the concept of “tipping point species”—birds that have lost more than 50 percent of their population over the last 50 years, including iconic game birds such as the greater sage-grouse and the lesser prairie-chicken. The hosts emphasize both the hope and urgency contained in the report: citizen science tools like eBird empower everyday birders to contribute critical data, while conservation policies such as the Duck Stamp Program have proven their value in reversing declines. Yet the episode also warns of looming threats, including deep funding cuts to federal conservation programs and the risk of losing the scientific foundation for hunting regulations. Ultimately, the conversation serves as a call to action for hunters, birders, and citizens alike to participate in monitoring, advocacy, and habitat conservation to ensure the future of North America’s birds.

In this episode, AJ and Gabby take a break from their regular programming to discuss the sale of public lands as part of the federal budget reconciliation bill. 

On June 11, 2025, the Energy and Natural Resources Committee Hearing to Examine the President’s Budget Request for the Department of the Interior for Fiscal Year 2026 took place. In it, senators discuss “The “Mandatory Disposal of Bureau of Land Management Land And National Forest System Land for Housing,” which would require the sale of 2-3 million acres of Bureau of Land Management (BLM) land and U.S. Forest Service (USFS) land within a five year period.

BLM and USFS land is public land—YOUR land. Why are senators trying to include the sale of our land as part of the budget reconciliation bill? Some theorize that it’s part of a systematic, long-term approach to shift public lands towards private control. The current reconciliation effort isn’t an isolated policy—it’s the culmination of decades of ideological moves.

If you care about the American public retaining access to the land we collectively own, now is the time to speak up. Contact your senators via social media, phone, email, or snail mail and tell them what you think. Three million acres of your lands are on the line.

How an 1885 dissection unraveled a hidden story about invasive worms and the migration routes of the American woodcock in North America.

In 1887, Frederick Webster, a taxidermist from Washington, D.C., wrote a short article in a scientific journal. In it, he described dissecting a woodcock from Martha’s Vineyard that had a crop filled entirely with ferns. Why did this woodcock stray from its usual diet of invertebrates? A.J. and Gabby, hosts of the Project Upland Podcast, search for the answer—only to uncover the surprising story of invasive worms in North America. 

Together with woodcock researcher Dr. Amber Roth and soil ecologist Dr. Peter Groffman, we learn how eco-engineering has destroyed native landscapes, contributed to the spread of ticks and invasive plants, and more. From woodcock migration during the Ice Age to the tobacco trade, this investigation is full of twists and turns.

Clarification Note
After the release of this episode, Dr. Dahlgren provided helpful feedback to clarify a couple of technical points related to telemetry and radio-marking methods:

• Rump-Mount vs. Backpack GPS Radios: In this episode, we referred to GPS radio units used in research. It’s important to note that rump-mount GPS radios, which are used in our discussion, secure around the legs and hips. Backpack-style radios, in contrast, have straps that go around the wings and breast. Backpack-style marking has been shown to have significant negative effects on survival in most gamebird research.
• Telemetry Terminology: The term telemetry refers to all radio-marking and monitoring activities with wildlife, including GPS technology. In some cases, we might specify “GPS telemetry” or “VHF telemetry” to distinguish between newer GPS-based tracking and the older method involving ground or aerial tracking.

These distinctions don’t impact the main takeaways of the episode, but we appreciate the additional insights from experts in the field.
