John Nores | The Hidden War on America's Public Lands | Tom Rowland Podcast Ep. 654

John Nores is a retired California game warden who spent decades investigating illegal marijuana grows on public lands and the environmental devastation they cause. In this conversation, John reveals the hidden war happening in America's wilderness areas, where drug cartels have established sophisticated operations that poison waterways, kill wildlife, and threaten hikers and hunters. He shares stories from his new book "Hidden War" about confronting armed growers, discovering the staggering scale of environmental crimes, and why most Americans have no idea this is happening in their national forests. This episode will change how you think about public lands and the threats facing our wild spaces.

The Environmental Crime Most Americans Don't Know About

John Nores opens up about a threat hiding in plain sight on America's public lands. While most people think of national forests and wilderness areas as pristine natural spaces, John reveals that drug trafficking organizations have established elaborate marijuana cultivation operations throughout these areas. These aren't small-scale grows—they're sophisticated operations that use banned pesticides and poisons at levels that would shock most people. The chemicals don't just stay at the grow sites; they leach into streams and rivers, killing fish and wildlife while threatening anyone who drinks from or recreates in these waterways. John explains how these operations target some of California's most beautiful and remote areas, and why the average hiker, hunter, or angler has no idea they're there. The full story of how John discovered the scale of this problem starts at the beginning of the episode.

Armed Confrontations in the Backcountry

As a game warden investigating these illegal grows, John Nores found himself in situations most law enforcement officers never face. He describes encounters with armed growers in remote wilderness areas, where backup could be hours away and cell phone service doesn't exist. These aren't casual marijuana users—they're often connected to Mexican drug cartels and will defend their operations. John shares specific incidents where he and his team had to make split-second tactical decisions in terrain that favored the growers. The danger isn't just for law enforcement; John explains how unsuspecting hikers and hunters have stumbled into these operations and faced threats or worse. The level of violence and intimidation these organizations use to protect their grows is something most people associate with urban drug trafficking, not America's national forests. John's most intense confrontation story unfolds in detail during the middle portion of the conversation.

The Pesticide Crisis Killing Wildlife

One of the most shocking revelations John Nores shares is the sheer volume of banned pesticides and rodenticides used at these illegal grow sites. These aren't agricultural chemicals approved for use—they're substances banned in the United States because of their toxicity to wildlife and humans. John explains how growers import these chemicals and apply them at rates far beyond what would ever be used in legitimate agriculture. The result is a cascade of death through the ecosystem. Rodents eat the poison, then predators like fishers, spotted owls, and other endangered species eat the poisoned rodents and die. The chemicals wash into streams during rain, poisoning fish and contaminating water sources that flow for miles downstream. John shares specific examples of wildlife die-offs linked to these operations and explains why the environmental damage will persist for years even after grows are eradicated. The full scope of the environmental devastation is detailed throughout the episode.

Why This Threat Extends Beyond California

While John Nores spent his career in California, he makes it clear that this problem isn't confined to one state. He discusses how these illegal cultivation operations have spread throughout the western United States, particularly in areas with large expanses of public land. The same drug trafficking organizations that establish grows in California's national forests are operating in Oregon, Washington, and other states with similar terrain and climate. John explains why these organizations choose public lands—it's free, remote, and the risk of prosecution is lower than private property. He also addresses the misconception that marijuana legalization has solved the problem, revealing how the illegal market continues to thrive and how these environmental crimes persist regardless of state law. The threat to public lands, wildlife, and outdoor enthusiasts exists anywhere these conditions align. John's perspective on the national scope of this crisis and what needs to change comes later in the conversation.

Final Thoughts from Tom

This conversation with John Nores opened my eyes to something I had no idea was happening on the scale he describes. When you think about national forests and wilderness areas, you think about pristine natural spaces where you can hunt, fish, and explore. You don't think about drug cartels running sophisticated operations that poison the land and threaten anyone who gets too close.

John's stories from his career as a game warden are intense. The confrontations he faced, the environmental devastation he documented, and the danger these operations pose to regular people using public lands—it's a hidden war that most Americans have no idea is happening. His passion for protecting wildlife and wild spaces comes through in every story he tells.

If you care about public lands, wildlife conservation, or just want to understand a major threat that's flying under the radar, you need to hear this conversation. John's book "Hidden War" is worth picking up too. This is one of those episodes that will change how you think about the places you love to spend time outdoors. Listen to the whole thing.
