In this video I demonstrate how to use an increment borer to core a Ponderosa pine tree. I address how to choose the correct location along the trunk to avoid too much bark, which can gum up the inside of a core, or reaction wood in growth due to microtopography or disturbance. Additionally, I explain how to hopefully achieve the pith (oldest growth/cells) when coring, while understanding that capturing the pith doesn't always happen.
I’m a Geography professor at Eastern Washington University interested in dendroarchaeology, paleoenvironments, and science communication. I’m the Director of the dendrochronology lab at EWU and frequently work with students on tree ring projects. Interested in learning more about #treerings, #Geography, or future #geoscience opportunities at EWU? Contact me at [email protected] and let’s chat!
