This shows the entire area of the North Dry Canyon natural area. Each red cross represents a single juniper tree of 18 inches or greater at breast height, DBH. after a training run around the waste, water treatment plant we began from the south end just north of the first street stairs before skipping across the canyon to the area immediately below West Rim Park. The black lines that you see cutting up the canyon floor define polygons areas created by the cities GIS staff to to help us break up the entirety of the project into chunks that made sense as you worked on the ground.
