Arizona White Oak, Emory Oak, Gamble Oak, Alligator Juniper, Shaggy Bark Juniper aka Utah Juniper, Southwestern Choke Cherry, Mountain Mahogany, Ponderosa Pine, Pinon Pine, White Fir and Aspen. Though many other varieties grow in my area this list is of the true native species within 20 miles of my home.
Mostly conifers - douglas fire, ponderosa pine, lodgepole pine (nearly gone from beetles), tamarack (a deciduous conifer), some spruce, grand fir, aspen in the wet areas, and apple. Those are the natural trees, perhaps the apple was planted some time back, I don't know. We have a few maples, but I am pretty sure they were planted.
Locust Post covered a lot growing here. Add tupelo, butternut, black walnut, hackberry, mulberry, poplar. dogwood. Welcome Howiff !
cedar and silver maple grow like weeds here. along with hedge, (osage orange). catalpa, black walnut, mulberry, hackberry. red oaks, white oaks, pin oak, i also planted, burr oak, hop hornbeam, big leaf maple, autumn blaze maple, London plane trees, sycamore, royal red maple, bald cypress, green giant arborvitae's, red wing maple, river birch, also apples, pears, and a paw paw tree. I like trees.
Not that I've seen. Douglas Fir have tighter needles that are far more green. If they do exist in my area I'd need to have someone show me to them. For the most part Yavapai County has a low elevation forest that lacks many trees that can be found at higher elevations within Arizona. Spruce and Bristlecone Pines for instance. One tree I failed to mention that is native would be the Arizona Walnut. That one is everywhere.
Here in the Puget Sound area close to the salt chuck we have Doug Fir, Hemlock, White Fir, Cedar, Madrone, Big Leaf Maple, Western Cherry, Alder, Cottonwood, Western Ash, Locust, Oak, Apple, and Pear. Lots of others, I'm sure, But these are the ones that come to mind right now.
