The diversity really amazes me sometimes. We are in an area that is primarily creosote bushes, but you can find patches like this one. Not far from here there a LOTS of cacti species, or Joshua Trees, or Yucca zones. There are areas with lots of brush like rabbitbrush and sagebrush, and there are places with enough Mesquite trees to keep cattle fed (that is some good sweet meat btw). It's never quite the same, any more than the forest is just the trees.
