About Completely Arbortrary

This weekly podcast is a scientific look at trees and how they affect and are affected by everything, hosted by master arborist and environmental educator Casey Clapp and his tree-curious friend and musical artist Alex Crowson. Each episode features a tree from around the world and a discussion about its unique position in culture, ecology, and history. These discussions can range from urban forestry and evolutionary biology to folk mythology and popular culture. The hard science is framed in plenty of silliness, with a casual tone, games and parody songs, and the titular arbitrary numerical rating of the tree at the end of each episode.

This podcast's mission is to provide approachable science to audiences of all experience levels and reconnect people to the natural elements around them, whether deep in the forest or just outside their front door.
