ReThink History: Ground Truth: Forest Service Research

Since 1908, the U.S. Forest Service has run a hidden network of Forest and Range Experiment Stations and more than eighty experimental forests — outdoor laboratories where the same hillsides have been measured for a century. This is where American forestry stopped guessing and started knowing: where ponderosa regeneration was cracked, rangeland ecology was invented, the Dust Bowl was answered with a thousand-mile wall of trees, and acid rain was discovered. Ground Truth tells the rise of that science and the present-day fight over its future. History-first, working from primary documents and peer-reviewed scholarship, honest about what's verified and what's contested. Narrated by AI voices from sourced, human-reviewed research.
