Background information and definitions
Moorings, permanent or temporary, provide an alternative to anchoring and allow for reduced anchoring in the area. Moorings can be provided for recreational vessels, as well as commercial vessels up to specific sizes. However, moorings also impact subtidal benthic invertebrates through chronic damage and physical disturbance to the seabed (Griffiths et al. 2017). Moorings that reduce or avoid contact with the seabed, known as eco-moorings, could be used to reduce disturbance and prevent physical damage to subtidal benthic invertebrates from mooring structures (Demers et al. 2013). Evidence for other interventions related to mooring are summarised under “Threat: Transportation and service corridors – Periodically move and relocate moorings”, and “Provide additional moorings to reduce anchoring”.
