Muir Woods National Monument

In 1905, industrialist William Kent purchased 295 acres of old-growth redwood forest and donated it to the federal government to protect it from logging. President Theodore Roosevelt accepted the donation and established Muir Woods as a national monument in 1908, establishing one of the nation's first protected old-growth forests.

The "Saving Muir Woods" interpretive sign displayed a timeline covering the monument's founding and conservation history. In 2021, park staff added yellow sticky note annotations to the original timeline, providing critical context about Indigenous stewardship of the land, women's contributions to conservation efforts, and the problematic history of eugenics within the early conservation movement.

Under Executive Order 14118 and Secretarial Order 3431, the sticky note annotations were ordered removed. The original sign remains in place, but the additional historical context provided by park staff—developed to address significant gaps in the original interpretation—has been eliminated.

Why this matters: This removal demonstrates how contemporary historical interpretation can be censored through selective removal of supplementary context, leaving visitors without critical understanding of complex histories within conservation movements.

Coast redwoods are Earth's tallest trees, capable of living for over 2,000 years. These ancient giants play a critical role in climate regulation and carbon sequestration, storing vast amounts of CO2 in their massive wood structure.

The "Are We Protecting Redwoods?" interpretive sign addressed climate change impacts on these iconic trees, including fog decline and its effects on redwood water uptake. Coast redwoods depend on coastal fog for approximately 40 percent of their water intake. Since the early 20th century, fog occurrence along the California coast has declined by roughly 33 percent—a trend linked to warming ocean temperatures and climate change.

The sign discussed how redwoods serve as carbon sinks and the urgent need to protect them as climate change accelerates. It was completely removed from a circular boardwalk, with no interpretation left to explain the ecological significance of the monument's namesake trees or their vulnerability to ongoing climate shifts.

Why this matters: The removal of this climate science interpretation represents the erasure of factual information about environmental change and the redwoods' ecological role in carbon storage—critical context for visitors seeking to understand the forest's contemporary challenges.
