Nan wrote Australian Rainforest Plants I-VI, for which Hugh took the photographs. They revised and republished Alex Floyd’s book,Rainforest Trees of Mainland South-Eastern Australia and collaborated on the interactive identification key Rainforest Plants of Australia – Rockhampton to Victoria. Both Nan and Hugh have been involved in forest activism since the Terania Creek blockade which was based on their property adjacent to the disputed forest. They continue to regenerate, protect and advocate for rainforests. Their two daughters, Terri and Elke continue as activists in their own right.
