DISTRIBUTION AND OCCURRENCE
SPECIES: Leymus ambiguus | Colorado Wildrye 



GENERAL DISTRIBUTION : 
Colorado wildrye has a limited distribution along the east slope of the
Rocky Mountains in Colorado and New Mexico [2].  It occurs scattered
along the Colorado Front Range extending from Rocky Mountain National
Park southward to La Veta Pass in Herfano County.  Seemingly disjunct
populations also occur in the Magdalena and Manzano mountains of New
Mexicxo.  Although no specimens were found during field studies, Atkins
and others [1] speculated that plants occur in the intervening mountain
ranges.

Colorado wildrye as classified by Barkworth and Atkins [2] has a much
more restricted distribution than that described in other taxonomies.
