Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Rye Brome faces severe decline due to modern agricultural practices that favor herbicide-resistant crops and intensive farming methods that eliminate this once-common arable weed. The widespread use of selective herbicides specifically targeting grass weeds has dramatically reduced populations across its former range. Additionally, improved seed cleaning technologies have largely eliminated this species from commercial grain supplies, cutting off a major dispersal pathway that historically maintained populations across agricultural landscapes.

Threat summary

Habitat

Rye Brome typically inhabits arable farmland, particularly cereal crops, waste ground, and disturbed soils with moderate fertility. This annual grass thrives in traditional agricultural systems with winter cereals and can also be found along field margins, roadsides, and other areas with periodic soil disturbance.
