Small, isolated populations can be especially sensitive to poor habitat conditions due their limited capacity adapt or disperse. Management of such populations, with an objective implement the most effective strategies, is a conservation priority. The Norfolk Island morepork ( Ninox novaeseelandiae undulata ) Critically Endangered hawk‐owl endemic estimated population 25 individuals. This species faces compounding threats from degradation and loss, as well inbreeding depression. It presents exemplar for development management strategies top‐order predators in small, systems. We paired fine‐scale light detection ranging‐derived variables tracking data quantify suitability relative importance environmental variables. Maximum entropy modeling indicated vegetation patch size canopy height were important variables, moreporks more likely found larger patches heights above 7 m. Morepork presence was not strongly influenced by type wooded vegetation; rather, appears generalist occupier forested areas. demonstrate that suitable during breeding season currently constrained, coverage one‐third (34%) island carrying 36 pairs. Restoration native forest cleared areas adjacent existing patches, specific goal increase size, optimized strategy situ capacity. study has demonstrated how inform targeted restoration enhance threatened recovery.
