Background information and definitions
Recreational boating, including powerboats, sailboats, or man-powered vessels such as rowing and paddle boats, can impact subtidal benthic invertebrates through physical damage from anchors and propellers (Lloret et al. 2008; Milazzo et al. 2002; Whitfield et al. 2002), disturbance from fast flowing water or suspension of sediments, or pollution (Hammerstrom et al. 2007). Recreational boating could be limited in one area, by restricting the activity in space and time (limits on duration and occurrence, delimiting allowed areas). Boating could also be ceased by setting a permanent or temporary closure (e.g. seasonal closure), or prohibited through bylaws. This may help reduce the intensity of the threats associated with these activities and potentially allow subtidal benthic invertebrate communities to persist or recover over time. When restrictions of recreational boating occur in the context of a marine protected area, evidence is summarised under “Habitat protection”, including “Habitat protection - Designate a Marine Protected Area and set a no-anchoring zone”.
