The main conclusions indicate that baseline conditions were well-characterised, with no significant deviations detected in benthic, fisheries, or marine mammal communities, nor any immediate issues reported by fishermen or stakeholders. Baseline studies determined that the wind farm area is outside current boundaries of potential marine Special Protection Areas (SPAs), though future SPA delineation for red-throated divers remains uncertain. The monitoring also provided foundational data for ornithological populations, noting the need for methodological improvements in bird flight height and movement detection, and highlighted that benthic and aerial survey methods require further refinement for higher precision. Key recommendations include ongoing, targeted monitoring—especially for bird and fish populations, EMF, noise, and vibration—refinement of survey techniques, continued stakeholder engagement, and the use of improved technology to ensure comprehensive long-term evaluation of potential and emerging environmental impacts.

Subtidal (benthic) sediments were sampled from 17 agreed locations in and around the development site using a Day Grab. Suspended sediments are being monitored to determine any near and far field effects of windfarm construction and post-construction conditions. Benthic organisms: Three replicate samples were obtained from the 17 locations used for the subtidal sediment sampling by the same methods. Consultation with fisherman and appropriate bodies has been undertaken and is ongoing through the Fisheries Liaison Officer....abundance or change in distribution of their catches Marine mammals: site-specific counts being carried out in combination with ornithological surveys. Ornithology: Surveys were conducted for 5 objectives for ornithological monitoring.
