Species and habitats identified as needing protection under national or international agreements are effectively protected or conserved through the appropriate national, regional or international mechanisms. . 201403 Same as last reported determination ACS-IE-AA-001 D10 HabBenAll HabPelagAll PresInputLitter The amount of litter, and its degradation products [see Note], on coastlines and in the marine environment is reducing over time and are at levels which do not result in harmful effects to the coastal or marine environment.
