Surveys of the endangered and native waterbird species on the ranch were developed in 2020. There are four endangered species on the ranch: Aeʻo or the Hawaiian stilt (Himanoptus mexicanus knudensi), ʻAlae Keʻokeʻo, or the Hawaiian coot (Fulica alai), ʻAlae ʻula or the Hawaiian common gallinule (Gallinula chloropus sandvicensis) and Koloa Maoli or the Hawaiian Duck (Anaswyvilliana). Surveys aim to assess population trends and inform ranch management of wetlands and waterways where these birds are nesting, foraging and loafing.
