In the United Kingdom it forms dense, even swards of fine, hair-like stems in recently disturbed habitats, such as 3-10-year-old pulverised fuel ash. It is typically displaced by perennial grasses after about a decade.

Invasive speciesEdit

Vulpia myuros is considered a noxious weed and invasive species in places where it is not native, especially in areas with a Mediterranean climate.[3] For example, it is widespread in California, where it is now a dominant species in many types of grassy habitat.[3]
