Identifying priority habitat for conservation and management of Australian humpback dolphins within a marine protected area

A critical mismatch between dolphin habitat and marine protection zones has been identified, with 90% of high-probability areas for Australian humpback dolphins located in multiple-use zones where extractive activities are permitted. This finding underscores the urgent need to reassess spatial planning and management strategies within the Ningaloo Marine Park (NMP) to better protect this globally Vulnerable species. The study employed an ensemble species distribution modeling approach, combining data from six algorithms using systematic boat-based surveys conducted between 2013 and 2015. Key ecogeographic variables such as water depth and proximity to the coast were analyzed, revealing a strong preference for shallow waters (5-15 meters) within 2 kilometers of the shore. This research highlights the importance of prioritizing coastal conservation efforts to mitigate human-induced threats and ensure the long-term survival of this inshore delphinid.
