A list of poisonous plants is useless, as, for instance, in my neck of the woods, I will NEVER see a saguaro cactus in the wild. And, in Arizona, you probably wont run into too much poison ivy.
Saguaro cactus is prickly, but it's not poisonous. As for poison ivy, you definitely can find it in Arizona (as I can tell you from personal experience
).
Other reference info:
If you have a rifle, the hold over at different ranges.
If you have anything with a two-stroke engine, the amount of oil to mix with a tank of gas.
The length of your pace.
Various useful lashings.
