Background information and definitions
Utility and service lines can impact subtidal benthic invertebrates through physical damage and habitat loss. Along with associated infrastructures (Brigitte et al. 2018), it may be possible to leave utility and service lines in place after decommissioning (Ekins et al. 2006). This may avoid the threats associated with disturbance and physical damage from the removal of these structures. Evidence related to the potential benefits of removing pipelines in places are summarised under “Threat: Transportation and service corridors – Remove utility and service lines after decommissioning”. Evidence related to promoting biodiversity around subsea cables and pipelines are summarised under “Habitat restoration and creation – Cover subsea cables with artificial reefs” and “Cover subsea cables with materials that encourage the accumulation of natural sediments”.
