Cold-water　coral　LopheJia　pertusa　is　the　most　common　reef　framework-forming　species　in　the　North　Atlantic,　which　builds　complex　reef　structures　supporting　a　high　diversity　of　benthic　species.　L.　pertusa　reef　is　vulnerable　to　anthropogenic　impact.　Mapping　L.　pertusa　distribution　is　fundamental　for　resource　management,　but　challenging　given　the　typical　remoteness　of　their　habitat.　In　this　study,　we　used　MaxEnt　to　predict　the　potential　distribution　of　L.　pertusa　at　the　Rost　Reef　on　Norwegian　margin,　based　on　terrain　variables　at　multiple　scales　(30,90　and　170　m).　MaxEnt　performed　well　in　each　of　the　ten　runs,　and　successfully　predicted　the　potential　distribution　of　L.　pertusa　at　Rost　Reef.　The　suitable　habitat　of　L.　pertusa　was　predicted　to　occur　predominantly　on　the　SW-NE　running　ridges.　Jackknife　tests　indicated　that　the　terrain　variables　mean　curvature　and　plan　curvature　at　scale　170　m　were　the　most　useful　parameters　in　prediction　when　used　in　isolation.　The　ridge　structures　at　Rost　Reef　are　likely　to　play　an　important　role　in　influencing　the　coral　distribution　by　enhancing　the　bottom　current,　therefore　beneficial　for　feeding　of　the　species.
