Regional Impacts
| Ecological Impact | Competition | |
| Coral reefs in a marine protected area at St. Johns, US Virgin Islands, showed a trend of decreasing coral cover and increasing macroalgal cover. On one occasion, in 1998, Halimeda so. (presumably H. opuntia was the dominant species- at most other times it was the brown alga Dictyota sp.. (Edmunds 2002). | ||
