Why This Map Exists

×

This data belongs to the American people, who need to know what is being done to our National Parks. This administration is trying to use our public lands to erase history and undermine science.

Executive Order 14253 “Restoring Truth and Sanity to American History” and Secretary Order 3431 directed parks to censor any content “that inappropriately disparages Americans…or that emphasizes matters unrelated to the beauty, abundance, or grandeur” of natural features.
Why Are They Censoring Science and History?

Dismantling trusted sources of science and history makes their agenda of lies easier. Profiting from coal and oil is a lot easier if the impacts of fossil fuels are censored at sites like Muir Woods, Glacier, Acadia, and Everglades.

It’s easier to illegally detain people if we forget the true stories of Japanese-American incarceration in World War II, told at national park sites like Manzanar and Minidoka and Amache and Tule Lake and Honouliuli.

Propping up systemic racism is easier if you hide the evidence of the atrocities of chattel slavery, Jim Crow, and white nationalism at park sites like Medgar and Myrlie Evers Home, Cane River Creole, Rock Creek, and Independence Hall.

Most of all, they want to turn the American people against their national parks. They want to discredit the national parks and set the stage to privatize them.

Look at what they are censoring. Study it. Save it.
Find other people who care, and organize to fight back.
Build community around the science and history they want to erase.
And help us stop them.

Our Parks Need Your Voice

The Department of the Interior is removing and revising historical materials across the National Park System under Secretary's Order 3431. Congress has the power to stop this — but they need to hear from you.
443 park history entries with documented artifacts have been flagged, revised, or removed.
Momentum is building. On March 19, the NPCA and a coalition of historians, scientists, and park advocates filed for a preliminary injunction in federal court to halt the censorship. 53 House Democrats led by Rep. Jared Huffman are pushing to block funding for SO 3431. Add your voice to the pressure.

📰 This Week in Park Censorship

Apr 19 – Apr 30, 2026 · 5 new developments
🏛️ Truth in NPs Act ⚖️ Resource Diversion Argued 🍁 Tribal Consultation Mandated

Where the Fight Stands

On April 28, Reps. Sharice Davids (KS-03) — one of the first two Native American women elected to Congress — and Dan Goldman (NY-10) introduced the Truth in National Parks Act, legislation that would bar the Interior Department from removing historically and culturally accurate interpretive materials from national parks and require restoration of any content removed since January 20, 2025. The bill goes beyond a simple reversal mandate: it codifies a requirement for tribal consultation before any future changes to exhibits about Native American history and directs a comprehensive report on co-stewardship agreements between Indigenous communities and federal agencies. The measure targets the administration’s removal directive head-on, transforming what began as emergency advocacy into a legislative effort to permanently limit Interior’s unilateral power over historical interpretation.

Four days earlier, on April 24, the conservation coalition led by the National Parks Conservation Association filed new briefing in federal court arguing that Interior’s orders have caused concrete organizational harm — diverting resources from core missions and pressuring members to either self-censor or defy best practices for historical accuracy. The dual-track strategy is now clear: while litigation seeks immediate injunctive relief by demonstrating ongoing damage to organizational capacity, the Davids-Goldman bill aims to embed protections directly into statute, ensuring that no future administration can unilaterally scrub exhibits on slavery, Indigenous nations, or climate science without tribal input and congressional oversight. The week marks a pivot from reactive defense to structural counteroffensive.
