SLO Tree Drama: I Got an Expert Arborist to Explain Why We Approved Removing This Oak, Then Decided It Could Stay? | Up+Adam

The big oak at Monterey and Nipomo in downtown San Luis Obispo is staying put. That is the good news. The bigger question is how we got here.

Earlier this year, the San Luis Obispo City Council approved removal of the oak after arborists working with SLO REP and the City concluded the tree was extremely unlikely to survive construction of the new theatre. Then volunteer arborists stepped in, the root system was physically explored and pruned as part of a possible relocation effort, and new information emerged. The root system the tree depends on appeared to be smaller than previously thought. SLO REP has now reversed course and says the tree can remain in place while construction moves forward.

Adam brings on expert arborist Paul Koenning to unpack what that actually means. How much can an arborist know about a mature oak's root system before excavation? How different can a real root system be from the protection zones used in planning? What do clean root cuts do to a mature tree? And after pruning roots in preparation for a move that is no longer happening, what should the City, SLO REP, and the community be watching over the next several years?

Paul also explains why season matters when moving large trees, why root establishment can take years, what signs of stress matter most, and why a tree that looks green today can still require long-term monitoring. He brings decades of hands-on experience with live oaks and currently works as an arborist on the Property & Barn team at a well respected local winery in Paso.

This is not about turning the oak into a political football or finding a villain. It is about understanding the science, understanding what changed, and asking what this tree needs now if everyone involved is serious about giving it the best chance to thrive.
