  • EDGE species: Green turtle Chelonia mydas
  • Active: 2019 - 2022


Jonathan is currently studying for an MSc in Marine Science at Universiti Malaysia Sabah. He first found his passion for sea turtle conservation in 2014, and has been committed to study them ever since. He believes that there is a lot more that we can be doing to protect sea turtles and other marine animals and he wants to be at the forefront of these efforts.

Jonathan hopes that the Fellowship will allow him to learn more about different approaches to marine conservation. He looks forward to meeting new people from various fields of study who could prove to be valuable connections as collaborators in future research.

EDGE Project

Jonathan’s project aims to identify key areas for the conservation of the population of foraging green turtles in Mantanani. His objectives are to:

  • Establish the population density and distribution of green turtles in the shallow waters of Mantanani
  • Identify high risk areas for these foraging individuals through participatory mapping of fishing grounds and tourism activities in the Mantanani Islands
