Apart from the role trees play in sustaining life on Earth, they also provide homes for an enormously diverse range of vertebrate and invertebrate species. If you want a project that is relatable and presents many pathways for artistic and natural history storytelling, then this is the one for you. I have a large number of trees across Australia that I like to revisit each time I pass by. It feels like visiting an old friend – some of them have been in my life for over forty years!
