Our collection represents a portion of the plants in the upper Sacramento Valley and Shasta Cascades region of Northern California. Plants are collected on land managed by the Bureau of Land Management Redding Field Office. Redding BLM herbarium's main focus is vascular plants, however some non-vascular plants have been collected. The Redding BLM office covers many different types of ecosystems that range from ecosystems with serpentine soils to wetlands and vernal pools. Collections range back to the 1960s; about 1,000 collections have been made.
