Vulpia myuros

Ecology
An annual growing by railways, on walls and waysides, in pavement cracks and on waste ground in built-up areas. Occasionally found as a weed of cultivation and as an introduction from wool shoddy, grain and grass-seed mixtures. Lowland.
Status
Archaeophyte
Trends
Even allowing for the possibility that this species was under-recorded in the past, it is clear that V. myuros has become increasingly frequent across much of its range since the 1962 Atlas. It is likely that the plant has colonised many areas via the rail network.
World Distribution
As an archaeophyte V. myuros has a Eurosiberian Southern-temperate distribution; it is widely naturalised outside this range.
