Interestingly enough I just found out one of the issues with Arizona is that the Cacti have been allocated to the Chihuahuan Desert instead of the Sonoran Desert for AccuSeason. They use https://ecoregions.appspot.com/ to designate the vegetation. Based on the information provided below, the Sonoran Desert region should have been designated for Cacti, and the Chihuahuan Desert for scrub and woodland vegetation. Basically, it's looks like the areas got flipped. Hopefully this is something they will take a look at again. Otherwise, I greatly enjoy how the app gives me a different experience every few weeks.
