Katie Holten (Dublin, 1975) is an artist and environmental activist. She represented Ireland at the 50th Venice Biennale. At the root of her practice is a study of the inextricable relationship between humans and the natural world. While excavating hidden histories, ecologies and stories of specific places, she creates drawings, sculptures, books, public artworks and ephemeral works that illuminate the overlooked or forgotten. Interested in exploring possibilities for multispecies storytelling and creating a way for humans to rethink their place in the Anthropocene, she made a Tree Alphabet and the book About Trees (2015). During lockdown last year she made a new Irish Tree Alphabet. Katie is currently developing an Explorer’s Guide to the Tree Alphabet, offering a free TREE SCHOOL curriculum to share with schools and families in Ireland.
