Hugh at al, Those ash you refer to in Colorado National Monument are Singleleaf Ash (Fraxinus anomala), a little known native tree of the Southwest that barely gets into our area. The "anomala" comes from its having a single, shovelhead-looking leaf, instead of the compound leaves of other ash. One of my favorite trees, to be sure. Having Black-chinned Sparrows apparently becoming part of the CO fauna is exciting for birders, but perhaps the reason yet another southwestern species is expanding its range northward isn't.
