Comments
In the Watershed, the tree has been cultivated (usually a cross between Robinia neomexicana and R. pseudoacacia) and occasionally has escaped. There are three records from the floodplain of the Rio Grande in Alamosa, 1976-1985; one from Costilla Co, 4 miles W of Hwy 159 near the New Mexico border; one from Del Norte on an old pioneer house lot. Note that the native tree, not the cultivated hybrid, is common in New Mexico counties bordering Colorado, as well as the southwest states of the USA. It follows the Rio Grande drainage through New Mexico, occupying canyons and dry slopes, and on into the tip of west Texas, but no farther down stream.
