may interfere with growth of native herbaceous species in grassland and hardwood ecosystems of the West Coast states. It is weedy in West Coast rangelands and agricultural systems, especially in cereal crops
Source? likely to be reintroduced:
Seeds attach to animals and clothes and can easily be moved by livestock, people or machinery. If they are a component of seed mixtures used for revegetation programmes, the grass may be introduced in large quantities to new areas. Vulpiamyuros is a prolific seeder and accumulates a soil seed bank; soil movement may contribute to its spread. If Vulpia seeds continue to be a component of seed mixes, the grass is likely to reach new sites.
Can outcompete native species. Forms dense swards and its shallow roots can impede growth of native grasses and forbs. Grows rapidly in early spring, successfully competing with slower-growing native perennials. Infested hay can cause injury to livestock due to the sharp seeds. A prolific seeder that accumulates a seed bank. Introduced as a contaminant.
