The situation

What’s happening to Cascade-Siskiyou

The only national monument in America designated solely for its biodiversity. Where the Cascade, Klamath, and Siskiyou ranges converge, species from three bioregions overlap in what scientists call an ecological wonder. Timber interests have fought its existence from day one, and the current review could finally hand them the victory they’ve been waiting for.
