Dr. Kellie Leigh, the executive director of the not-for-profit conservation organisation Science for Wildlife, conducts a health assessment on a koala named Pele as part of The Blue Mountains Koala Project, a population monitoring program spearheaded to plan for koala recovery in the region, in the Greater Blue Mountains World Heritage Area, near Jenolan, Australia, September 15, 2020.
