Lambrinos (2000) worked in maritime chaparral plant communities along California's central coast and found that mean shrub cover declined from well over 80% in uninvaded areas to under 5% in sites invaded by Cortaderia jubata and mean shrub species richness dropped from nearly 6 species per sample to about 1. Thus, this invasion alters vegetative structure and species composition. This figure is based on data from Lambrinos (2000).
