A checklist of the vascular flora of Yucca House National Monument and surrounding lands, Montezuma County, Colorado

摘要

Two hundred and sixty-one vascular plant species were documented for Yucca House National Monument and surrounding lands including seven new records for Montezuma County. This work was part of a biological inventory throughout the National Park Service as part of the Natural Resource Challenge, a legislative and administrative mandate. The study area is in the Montezuma Valley, where most land is in private or tribal ownership, and opportunities for plant surveys are limited. The flora includes threespecies tracked by the Colorado Natural Heritage Program: Centaurium exaltatum (Griseb.) W. Wight ex Piper (desert centaury), Penstemon breviculus (Keck) Nisbet & R.C. Jackson (shortstem beardtongue), and Penstemon lentus Pennell (handsome beardtongue).
