NEED IN SITU PHOTOS. The introduced annual bluegrass has been vouchered less than ten times from the Watershed, all from the west side of the Valley. Mainly the habitat is along trails and streams, suggesting naturalization of a grass that also, elsewhere, invades lawns and golf courses. Poa annual, of Eurasian origin, has spread to every state of the USA. It follows the Rio Grande drainage through New Mexico, with uncommon occurrences on down Texas to the Gulf of Mexico.
