Conservation of Biodiversity, Seagrass Ecosystems and Their Services – Safeguarding Food Security and Resilience in Vulnerable Coastal Communities in a Changing Climate: Dugongs and Marine Megafauna Surveys
Project:
Seagrass Ecosystem Services ProjectThis technical report presents standardized methods and findings from dugong and marine megafauna surveys conducted under the IKI-funded Conservation of Biodiversity, Seagrass Ecosystems and Their Services project. It outlines practical, cost-effective approaches for monitoring dugongs and other marine megafauna using drone-based aerial imagery and standardized image analysis, enabling surveys to be undertaken by local practitioners. The report supports long-term monitoring of dugong populations as indicators of seagrass ecosystem health and provides guidance to strengthen evidence-based conservation and management of seagrass habitats and the ecosystem services they provide.
