Klamath Mountains ecoregion

The Klamath Mountains ecoregion, designated as a Level III region by the EPA and CEC, spans northern California and southern Oregon. Notable for its serpentine soils, this area fosters high plant endemism due to nutrient-poor conditions and unique geobotanical communities. The climate varies from Mediterranean to alpine, supporting diverse vegetation types including forests, woodlands, and shrublands. Conservation efforts are crucial here due to threats like logging, mining, and invasive species, which endanger the specialized flora.

Subsections within this ecoregion include:

Each subsection details specific geological features, elevation ranges, and dominant vegetation, highlighting the region's biodiversity. External resources on conifer diversity in northwest California are noted for further exploration. The ecoregion's classification is part of broader systems by EPA and WWF, emphasizing its ecological significance and conservation needs.
