In the Elgin/Sonoita/Sierra Vista area you will run into Stag-horn and Beaver Tail cactus, not a lot, but enough to carry a comb to remove it from the dog. You didn't mention what type of Quail your after, the grasslands are noted for Scaled and you will, less frequently, run into Mearn's and Gambel. I hunt these areas often, let me know if I didn't answer your question.
