- Comments
- Strangely this most widespread of native cottonwoods in the USA may be adventive to the Watershed. Cultivated trees and their seedlings can be found on private properties and in towns, for instance at the headquarters of a former cattle ranch in the Baca NWR, or in the lawn of an elementary school administrative building in Del Norte. These are P. deltoides subsp. monilifera, or Plains cottonwood. The other subspecies is P. deltoides subsp. wislizeni, which has not been recorded in the Watershed despite being called the Rio Grande cottonwood. In New Mexico, both subspecies are "Found throughout the state along nearly all river drainages"—including that of the Rio Grande. Its variations are a "quagmire" "capable of sinking even the most fervent and accomplished taxonomist" (Allred, et al., 2020, III, part 2, p. 731). It follows the Rio Grande to within 50 miles of the Gulf of Mexico.
