The Upper Sacramento River Alluvium ecoregion includes the floodplains and terraces of the Sacramento River and lower Cottonwood Creek in the area between Redding and Red Bluff. It is flatter and has more cropland and irrigated hay and pastureland than the adjacent Tehama Terraces ecoregion (6e) that is mostly rolling and dissected woodlands and grasslands used for grazing. Although it has similarities to the northern parts of Ecoregions 7e and 7b in the Central California Valley, this narrow ecoregion is influenced by the surrounding oak woodlands. Natural vegetation consisted of riparian woodlands of Fremont cottonwood, California sycamore, willow, box-elder, and valley oak, and at higher elevations, some blue oak woodland and savanna.
