Arizona walnut is native to the American Southwest and Mexico. It grows primarily in riparian areas, near springs, and other areas with shallow groundwater, in mixed-deciduous, coniferous pine-oak, and oak riparian stringers, gallery forests, woodlands, and forests. Similar in habit, shape, and water budget to a pecan tree, this tree provides food for many kinds of wildlife with its small walnuts encased in a fruit that ripens to a gooey, black paste. The flesh and skin of the fruit can be used as ink or for dyeing cloth. 

Habitat Value: Attracts birds and mammals, edible nuts, good nesting tree.
