The freshwater diatom collection has specimens collected from a variety of habitats including streams from Southern California and Southern Alaska, and lakes and fens from Iowa. The majority of the specimens were collected as part of the CSULB Stream Ecology and Assessment Laboratory (SEAL) bioassessment efforts funded through the California State Water Boards and the Surface Water Ambient Monitoring Program. Aquatic Bioassay Consulting, Ventura, California, also provided material for processing. Most of the specimens were collected from the Santa Ana and San Jacinto watersheds. Most specimens are at the genus level and many have been identified to species.
