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.

Princess Mononoke (Hinoke)
Dec 28
1h 31m
Can we interest you in a forest bath? On the series finale of Treeyazaki, we discuss Princess Mononoke and the hinoki cypress (Chamaecyparis obtusa). A tree ripe with VOCs (volatile organic compounds) and rich tradition such as forest bathing, this tree is a quintisential Japanese conifer.

A Place for Everything (Keteleeria)
Nov 14
1h 4m
In the second of our “odd Pine family distant cousins” we talk Keteleeria (Keteleeria davidiana), and the perfect pocket of China where this and many other species call home.
Larchy Bark and the Trunky Bunch (Golden-Larch)
Nov 07
1h 1m
In this episode, we explore the golden-larch (Pseudolarix amabilis), a unique member of the pine family that feels a bit like the “weird cousin at the Pine family picnic.” Once native to the Arctic, this deciduous conifer now grows exclusively in specific regions of China, adapting over millennia to its new home. We also dive into a listener question about variegated leaves and why some plants sport these striking patterns.
NOT A MANGO, DO NOT EAT (Sea-Mango)
Oct 31
59m
WARNING: This is not a mango. Do not eat this non-mango, this Lord of Lies, this Great Deceiver, for it is the sea-mango (Cerbera manghas) and it absolutely will kill you. The story is a little more complicated, however, as this tree provides an undeniably invaluable resource... but is it worth the risk?
Stung By Thirty Wasps (Giant Stinging Tree)
Oct 24
1h
In this episode, we explore Australia’s infamous giant stinging tree (Dendrocnide moroides) and its neurotoxic hairs that cause agonizing pain. How fun(?)!
Parenchyma Schmarenchyma (Boojum Tree)
Oct 17
1h
Join us as we get weird with the Boojum tree (Fouquieria columnaris), a quirky desert oddball with some fascinating parenchyma. Plus, Casey reads an interminably long Lewis Carroll poem that gave this tree its name.
The 𝘹 Files (Munz Oak)
Oct 10
1h
Join us on a mysterious journey through time to discuss the Munz oak (Quercus x munzii), a curious hybrid of UNKNOWN ORIGIN!
