- Ecologist, Charles Darwin University
Hayley Geyle is an ecologist working in a hybrid role with Territory NRM and the Northern Institute (Charles Darwin University). She collaborates closely with Indigenous rangers and Traditional Owners on threatened species projects, with a particular focus on protecting bilbies in the Northern Territory’s arid and semi-arid zones. Through the Digital Women Ranger program, she helps build confidence and capacity for women rangers to use digital tools and data to tell stories about Country. Hayley is passionate about fostering meaningful partnerships that align conservation efforts with shared goals.
