Listen in as we talk about a niche and noble hobby: tree collecting. Author Amy Stewart joins us to discuss her newest book, The Tree Collectors: Tales of Arboreal Obsession, which profiles 50 different tree aficionados ranging from scientists cataloging rare species, to families preserving their heritage, and conservationists fighting to reforest their land. Their stories shed light on both the cultural and environmental necessity of trees—and how climate change, policy shifts, and financial barriers are all hindering their protection. Stick around for insights into the ways these collectors are benefiting biodiversity, and what roles you can play in the effort.
