Ecoregion in Rocky Mountains, ID

Generate High-Quality PDF

The deeply dissected Lochsa – Selway – Clearwater Canyons ecoregion contains cold, fast-flowing rivers. Local relief is greater than in the nearby mountains. Canyons become warmer and drier with increasing depth. Ecoregion 16c is dominated by Douglas-fir, grand fir, western redcedar, western larch, and western white pine. Ponderosa pine grows on lower, drier sites. The forest canopy is more closed than in the warmer and drier Ecoregion 16j. Extensive wilderness occurs and includes the Selway River watershed. Elsewhere, logging is common.
