Ecology


Flora

As a consequence of the geology, the mountains harbor rich biodiversity, with several distinct plant communities, including temperate rain forests, moist inland forests, oak forests and savannas, high elevation forests, and alpine grasslands. These communities form the Klamath Mountains ecoregion. One of the principal plant communities in the Klamath Mountains is
