Disclaimer: While I-Rank information is available over NatureServe Explorer, NatureServe is not actively developing or maintaining these data. Species with I-RANKs do not represent a random sample of species exotic in the United States; available assessments may be biased toward those species with higher-than-average impact.

Subrank I - Ecological Impact: Insignificant
Subrank II - Current Distribution/Abundance: Medium/Low
Subrank III - Trend in Distribution/Abundance: Medium/Insignificant
Subrank IV - Management Difficulty: Low/Insignificant
I-Rank Review Date: 05Mar2004

Screening Questions

S-1. Established outside cultivation as a non-native? YES
Comments: Established outside cultivation in the U.S. (Kartesz 1999). However, it is not persistant (Hitchcock and Chase 1950).

S-2. Present in conservation areas or other native species habitat? Yes
Comments: Cultivated for the grains, sometimes spontaneous in fields and waste places but not persistent (Hitchcock and Chase 1950). Occasionally found as a waif along roads and railways in the northeastern United States (Gleason and Cronquist 1991).
