Background information and definitions
Shipping, fishing, and other anthropogenic activities can impact subtidal benthic invertebrates through species removal or habitat damage. Specific areas of recognised scientific, ecological, or socio-economic significance can be designated as Particularly Sensitive Sea Area (PSSA) by the International Maritime Organization (IMO) because of their vulnerability and sensitivity to international maritime activities (IMO Resolution A.982(24); Kachel 2008; Lefebvre-Chalain 2007). Specific management measures can be taken within PSSAs to control for impactful maritime activities, such as ship routeing measures, the strict application of pollution legislation and waste or ballast discharge regulations, or the requirements for specific equipment on ships (Kachel 2008).
Inside PSSAs, the threat to subtidal benthic invertebrates from specific maritime activities is potentially removed or regulated, and previously impacted populations are, in theory, able to recover over time.
