Bromus nottowayanus

Accepted by Kartesz (1994 checklist) and by Leon Pavlick (Univ. British Columbia, Bromus specialist), although many past authors did not recognize this as a distinct species. Often included under or confused with Bromus purgans, Bromus pubescens or Bromus latiglumis. Taxon has a 5-nerved second glume.

The reported range of Bromus nottowayanus is widespread and occurrences may be much more common than has been documented in regions where the species is not recognized or is confused with other Bromus species. B. nottowayanus requires a habitat of mature, shaded, undisturbed, bottomland woods, which in general is threatened by logging.

Its range includes from New York south to Georgia (absent in Delaware and South Carolina); west through Tennessee, Alabama, Kansas, Arkansas, and Oklahoma; and from Arkansas northwest through Missouri, Iowa, Illinois, Indiana, Ohio, Michigan, southern Ontario, and Quebec. Also reported from Texas.

The largest threat to this species is habitat destruction by logging. Also threatening are horseback-riding, other human uses, and intrusion of habitat by invasive plant species [Note: the species referred to as invasive througout this ranking form, Symphoricarpos orbiculatus, is a U.S. native, common understory shrub found in forests in the extreme western Midwest and in the Great Plains. It only poses a problem in disturbed (e.g. grazed) understories, where it can become quite extensive and dense. It is known as buckbrush or coralberry. (Freeman, C., pers. comm. to M. Martinez, October 6, 1997)].
