Abstract

The eastern coast of North Sumatra supports one of the province’s remaining mangrove ecosystems, which provide critical ecological functions and serve as key habitats for resident and migratory waterbirds along the East Asian–Australasian Flyway (EAAF). This study surveyed the coastal wetlands of Labuhanbatu Utara Regency including mangrove forests, mudflats, and aquaculture ponds to document species composition, population size, and the conservation significance of the area. Fieldwork was conducted at multiple sites in Kualuh Leidong and Kualuh Hilir between 6–8 December 2024, complemented by earlier surveys from 2019 and 2020. Using concentration counts and block estimation methods during rising to high tide conditions, we recorded 36 waterbird species, consisting of 17 resident and 19 migratory species, with total counts of 4,602 individuals (2019), 7,695 individuals (2020), and 2,368 individuals (2024). Twelve species are legally protected in Indonesia, including Ardea alba, Mycteria cinerea, and Leptoptilos javanicus. Globally threatened species were also documented, such as the Endangered Milky Stork (Mycteria cinerea) and three Vulnerable species including the Chinese Egret (Egretta eulophotes). Several migratory shorebirds exceeded the 1% population threshold of the EAAF, notably the Tibetan Sand Plover (Anarhynchus atrifrons, 1.2%), Whimbrel (Numenius phaeopus, 1.4%), Eurasian Curlew (N. arquata, 1.1%), and Common Redshank (Tringa totanus, 1.2–1.3%). These findings confirm that the coastal wetlands of Labuhanbatu Utara constitute an internationally important site for migratory waterbirds, highlighting the urgent need for strengthened conservation and habitat protection in the region.

Abstract

Industrial landscapes are often perceived as degraded environments with limited ecological value. However, when managed responsibly, such areas can contribute to biodiversity conservation and environmental education. This study investigated the diversity, conservation status, and ecotourism potential of birds in the operational areas of PT Indonesia Asahan Aluminium (PT Inalum), located in Batu Bara Regency, North Sumatra. Bird surveys were conducted from August 2023 to May 2024 across three habitat types: residential green areas, plantation and shrub habitats, and coastal–mudflat zones. Data were collected through direct visual observations, supported by photographic documentation and sound recordings. Species identification followed Eaton et al. (2021), and conservation status was assessed using the IUCN Red List and Indonesian national protection regulations. A total of 103 bird species belonging to 41 families were recorded. Of these, 22 species are legally protected in Indonesia, and one species is listed as Endangered globally, the Milky Stork Mycteria cinerea. The study also documented 31 migratory species and several breeding records, including Nisaetus Limnaeetus, Pycnonotus analis, Treron vernans, Ploceus philippinus, and Merops philippinus, indicating the site’s importance for both resident and migratory populations. The diversity and breeding activity suggest that PT Inalum’s managed habitats provide suitable ecological conditions for birds despite industrial operations. These findings demonstrate that corporate-managed lands can serve as complementary conservation habitats and highlight their potential for birdwatching-based ecotourism and environmental education. Establishing a continuous monitoring program, strengthening wildlife management capacity, and developing interpretive facilities are recommended to enhance conservation outcomes and promote sustainable industry biodiversity integration.
