Burnt Wood Plank (Sugi)
To conclude our miniseries on logging, we discuss sugi (Crytomeria japonica), a unique conifer that hails from the forests of Japan. In a nation spared by colonization, where tradition and modernity coexist, sugi and its growing and processing methods are emblematic of this non-dichotomous dynamic. Yakisugi (or burnt cedar) is a method of treating sugi wood by means of fire, creating a phoenix-like rise from the ashes, making the wood more impermeable, and more resistant to insects and decay. Then, we play Family Tree: Mario Edition!Completely Arbortrary is produced and hosted by Casey Clapp and Alex CrowsonSupport the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Arboreal Corn (Monterey Pine)
What do you get when you treat trees like corn? A plantation, of course. And a whole lot of Monterey pine (Pinus radiata). A tree that grows stubby and wonky in its native range, the Monterey pine grows like a poster child for logging in New Zealand, where its stick-straight form makes it the tree of choice for an unthinkably large swath of logging land. But oh, that cone...Completely Arbortrary is produced and hosted by Casey Clapp and Alex CrowsonSupport the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Under The Tree (Jarrah)
Welcome to Australia, land of strange plants. Jarrah (Eucalyptus marginata) is no exception! This superfluously hardwooded tree of the Darling Range of western Australia is home to many a marsupial, and sports an astronomically deep root system. But when it caught the attention of voracious European loggers for its striking wood, Jarrah's future turned irreversibly grim.Completely Arbortrary is produced and hosted by Casey Clapp and Alex CrowsonSupport the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Wet Hot American Lumber (Eastern White Pine)
Logging has seen a stark evolution since its origins. What started as a wildly dangerous and often deadly process done largely by hand is now a multibillion dollar industry facilitated by manmade machines. Herein we meet our character, the eastern white pine (Pinus strobus), a ghost from the early days of American logging. In the first of a short series on logging, we hear the tragic tale of this quintessential pine species and the lumber barons who ensured its demise.Completely Arbortrary is produced and hosted by Casey Clapp and Alex CrowsonSupport the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Queen of the Canoe Crops (Noni)
1000 years ago, Polynesians reached the islands of Hawaii. On their seaworthy canoes were only a handful of plant species, but among them was the divisively flavorful botanical wonderdrug known as noni (Morinda citrifolia). Known for its funky flavors and breadth of influence on traditional Hawaiian medicine, this pan-tropical tree knows how to grow just about anywhere a canoe can bring it. Learn all about noni and the much broader classification of 'fruit', this week on Completely Arbortrary.Completely Arbortrary is produced and hosted by Casey Clapp and Alex CrowsonSupport the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

The Tree's Knees (Bald Cypress)
The devil went down to Georgia, where the Bald cypress (Taxodium distichum) lives its days in peace and harmony. This record-breakingly long-lived tree found the perfect place to call home--the swamps of the Southeastern United States. There, it sheds stereotypes as well as it sheds its needles, growing with grace and beauty against the harsh and dreary landscapes in which it resides. This deciduous conifer is without a doubt and from top to bottom a unique species. Then, we play a new game all about puns: A Little Bit Puntree, A Little Bit Log and Soil.Completely Arbortrary is produced and hosted by Casey Clapp and Alex CrowsonSupport the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Late SUCCESSION (Yellow Carabeen)
Late succession... the third and final act of a seemingly eternal stage play, and a self-perpetuating phase of the lifespan of a forest. The Yellow carabeen (Sloanea woollsii) dominates late succession in Australia. How and why is it so successful, and how does it set up generational success for its kind? In the final episode of our SUCCESSION series, we take a long look at the late stages of a forest, and discuss why it has the potential to go on forever. But nothing lasts.... Then, we put together our Board of Firectors at Crowson, Clapp, and Sons.Support the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Mid SUCCESSION (Red Alder)
Weed tree? Or... the unsung hero of mid succession forests? The red alder (Alnus rubra) is our official representative from mid succession forests, and the lens through which we view this second phase, the early adulthood, of forest growth. There are no shortage of benefits this tree provides to its habitat, so does it deserve its bad reputation? On our way to late succession, we find shade intolerant plants dying away, making room for our first "real" trees. But the saplings of today are the successors of tomorrow...Completely Arbortrary is produced and hosted by Casey Clapp and Alex CrowsonSupport the pod and become a Treemium MemberFollow along on InstagramFind Arbortrary merch on our storeFind additional reading on our websiteCover art by Jillian BartholdMusic by Aves and The Mini-VandalsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
