Regional Impacts
| Ecological Impact | Competition | |
| Heavy recruitment of B. schlosseri can affect subsequent community development. When recruitment was artifically enhanced (at Santa Cruz), communities remained dominated by B. schloserris for several months, compared to controls.(Sams and Keough 2012). | ||
| Ecological Impact | Habitat Change | |
| Fouling plates (at Santa Cruz) with enhanced B. schlosseri recruitment also had increased densites of Balanus crenatus and an unidentified sponge (Sams and Keoguh 2012). | ||
