Deforestation and Recovery of El Yunque and Puerto Rico's Forests
By the 1940s, Puerto Rico had been stripped to approximately 6% forest cover—down from near-total coverage before colonization. Coffee, sugar, and cattle replaced forests across the island. In 1876, King Alfonso XII proclaimed the Luquillo Mountains a reserve, and in 1903 Theodore Roosevelt designated it a federal forest. CCC reforestation in the 1930s-40s planted over 29 million trees. Forest cover recovered to approximately 53% by 2004.

The Trapiche System: Sugar Mills and Forced Labor in Colonial Puerto Rico
Beginning in the early 1500s, Spanish colonists established trapiches (sugar mills) across Puerto Rico's coastal plains, creating a plantation economy driven first by enslaved Taíno and later African labor. The trapiche system shaped the island's geography, ecology, demographics, and social hierarchy for three centuries.

Hurricane San Narciso (1867) and Colonial Relief Failures
Hurricane San Narciso devastated Puerto Rico on October 29, 1867, killing over 300 people and destroying thousands of homes. Spain's inadequate relief response contributed to the economic desperation and political anger that fueled the Grito de Lares uprising one year later.

El Yunque National Forest: Ecological Heritage and Colonial Land Use
El Yunque National Forest — the only tropical rainforest in the U.S. National Forest System — has been protected since 1876 (under Spain) and 1903 (under the U.S.), preserving 28,000 acres of biodiversity. But its protection also represents colonial land control: the forest is managed by the U.S. Forest Service, and Puerto Ricans have limited say in its management.
