Phenology is, roughly, a modern word for what was probably a most essential art for vast portions of human evolution: a lived relationship with the transformations and relationships in a specific living place over time.

Here, he answers some questions from one of his students in his presently running course. Lots of little unexpected jewels in here. Ryan introduced me to the formal nomenclature and some of the principles. I had become aware that nature had ‘her owl calendars’ and that these were ‘relationships that could be tracked according to the moon’, but my actual understanding was pretty feeble… so I really enjoy learning with Ryan.
