Phragmites australis (common reed)

Global genetic issues make it unclear which strains may be non-native in California. Non-native strains on the East Coast are major invasives there. Phragmites is sometimes problematic in California, but it is unclear whether it was historically present in all regions of California. Listing inconclusive.
