Are BioHavens safe?
Small BioHavens do not represent a safety issue that we know of. Larger ones could represent a boating hazard and we recommend that they be well marked so as to be visible under all conditions. Unless your BioHaven has been specially designed to support human activity, we recommend that you do not walk on them, or swim adjacent or underneath them. Roots that grow through BioHavens could represent a serious swimming or diving issue.
