Pinchot vs. Muir: The Argument the Forest Service Never Finished

They started as friends. Gifford Pinchot and John Muir walked the forests of the South and the West together in the eighteen nineties, two men who both believed the country was destroying something irreplaceable. They agreed on that. They agreed on almost nothing else.

Pinchot was a forester, trained in France and Germany, who believed that forests were resources to be managed for the long-term benefit of the public. Logging was not the enemy. Unmanaged logging was the enemy. The solution was professional management, scientific forestry, regulated harvests that kept more than they took. He built the Forest Service on this idea and ran it until nineteen ten.

Muir believed that some land should be kept entirely outside the category of resources. Not managed, not harvested, not grazed. Left alone. His founding of the Sierra Club in eighteen ninety-two was partly a direct response to watching what Pinchot's management philosophy could produce in practice.

The rupture came over Hetch Hetchy Valley in Yosemite, where San Francisco wanted to build a reservoir. Pinchot supported the dam because the city needed the water. Muir opposed it because the valley was irreplaceable. Pinchot won. Congress authorized the dam in nineteen thirteen, though the valley was not actually flooded until the dam was completed about a decade later. Muir died the following year.

The Shoshone National Forest operates under the Pinchot philosophy, which became the founding doctrine of all national forests. Wilderness areas within it operate under something closer to Muir's vision. Most of the forest's management controversies, from wolf reintroduction to grazing allotments to off-road vehicle access, are reruns of the same argument.

Neither man finished it.
