Research on the rare mangrove Avicennia lanata (Ridley) is based on the habitat affinity of this species on the coast of North Gorontalo observed during 2017-2019. The current search was carried out in geographically isolated areas (land and islands) using a combination of tracking and Point Centered Quarter (PCQ) techniques to observe the substrate condition and elevation of the mangrove patch habitat, as well as to observe the morpho-anatomical character of the stand. The results showed that the habitat affinity of A. lanata species in North Gorontalo covers a wide range of substrate types, including mud, sandy mud, sand, muddy sand, and sandy and muddy soil on land with an elevation of 5.11–6.57 MDPL. The morpho-anatomical character as a distinguishing feature of A. lanata species from other Avicennia species found in leaves, stems, and fruit, could only be observed clearly in individual stands and trees. This study recommends restoration/monitoring of mangrove species A. lanata (Ridley) with a mixed-species restoration approach and community-based co-planting in a long-term mangrove restoration program in the coastal area of North Gorontalo.
