A dead tree is just as important to a forest as a living one. When commercial forestry operations "clean up" fallen timber, they are actually removing the forest's natural water storage system. Large decaying, hollow logs act as massive biological sponges on the forest floor. Thanks to specialized fungi that break down the hard wood, the inside of a log becomes highly porous, capable of soaking up hundreds of gallons of rainwater. During intense summer droughts, these hollow logs serve as slow-release reservoirs, feeding water directly to the root networks of living trees and providing a cool, moist sanctuary for vulnerable forest wildlife.

Leaving deadwood on the ground isn't messy... it's essential hydrological engineering.

For 25 years, a single federal rule kept 58.5 million acres of America's wildest national forests off-limits to roads, logging, and industrial development. Now the USDA has filed a formal proposal to erase it entirely.
