What parts of California have no poison oak? It seems to be almost everywhere on the west coast how is this possible?
Much of the San Joaquin Valley and the desert southeast.
Not sure what you mean by this. Pacific poison oak is native to California.

It’s all over the place outside of deserts, the valley, and higher elevations. If you go hiking in California, you should just accept that you’ll see it all the time and just learn what its various forms look like so you can avoid it. Despite hiking year-round and getting close to lots of plants, I’ve only ever gotten it badly one time. Just be careful.
