In contrast to the volcanic and granitic rocks of similarly zoned Ecoregion 5g to the south, in the Northern Sierra Mid-Montane Forests ecoregion, metamorphic rocks are abundant, with Paleozoic metasedimentary argillite, phyllite, and quartzite, and some metavolcanics, as well as Mesozoic peridotite and serpentine. Elevations range mostly from 3,000 to 6,000 feet, with some lower west-end canyon elevations. This higher elevation mixed conifer forest has more white fir and Douglas-fir and less ponderosa pine than in the lower elevation Ecoregion 5h to the south. Jeffrey pine occurs on ultramafic rocks and some drier areas to the east. Black oak and tanoaks are common hardwoods, along with canyon live oak. Soil temperature regimes are mostly mesic and soil moisture regimes are mostly xeric.
