Episode 53: Boise’s Gernika Oak and Heartwood vs. Sapwood

(audio coming soon)

 

Happy Treefort 2019! In celebration of Treefort Music Fest, every episode of our show in March is about trees.

Boise is known for its trees. We’re not called the City of Trees for nothing. Casey introduces us to the first of several famous trees in Boise, the Gernika oak, located in front of the Cyrus Jacobs/Uberuaga House in the Basque Block.

It wouldn’t be completely inaccurate to say that trees are dead inside. Daniel explains the difference between heartwood and sapwood. One is composed of dead cells and performs an important structural role, while the other is responsible for moving water and minerals from the roots to the shoots.
