Nalini Nadkarni is a tree canopy scientist, which means she spends her time dangling off branches secured by mountain climbing equipment. One place she works is the Monteverde cloud forest in Costa Rica, which is swathed in mist and low hanging clouds. Another place she works is in prisons, where she brings conservation and sustainability projects to inmates. In one of these projects, inmates helped rear endangered frogs. But Nalini's career nearly came crashing to an end when she fell from a tree. She tells Jo Fidgen how she recovered and returned to climbing trees.
