False oat-grass (Arrhenatherum elatius)

False-oat grass (Arrhenatherum elatius) grassland is also widespread, but is particularly a feature of the western ranges, often indicating areas of past cultivation.

The larvae feed on various grasses such as Tufted Hair-grass, Festuca ovina, and Arrhenatherum elatius.

Thus, a particular type of mesotrophic grassland widespread in western Europe and dominated only by False Oat-grass (Arrhenatherum elatius) becomes Arrhenatheretum elatioris .

British NVC community MG1 (Arrhenatherum elatius grassland) is one of the mesotrophic grassland communities in the British National Vegetation Classification system.

The larvae feed on Agrostis stolonifera, Arrhenatherum elatius, Avenula pubescens, Deschampsia cespitosa, Festuca, Holcus mollis and Poa.

The larvae feed on Arrhenatherum elatius, Avena, Avenula pratensis, Festuca ovina, Phleum, Poa nemoralis and Poa trivialis.

The larvae feed on various grasses, including Brachypodium sylvaticum, Arrhenatherum elatius, Poa trivialis, Dactylis glomerata, Phalaris arundinacea, Melica nutans, Calamagrostis arundinacea and Calamagrostis epigejos.

In a five-year study conducted by Wilson et al. (2001) in Western Oregon, showed that mowing prairies of the invasive grass Arrhenatherum elatius allowed the native grasses Danthonia californica and Festuca roemeri to flourish and out compete the non-natives.

It is a principle species in the UK National Vegetation Classification habitat community the very widespread MG1 (Arrhenatherum elatius grassland), and thus can be found where Arrhenatherum elatius, (also known as False Oat grass), occurs.

Arrhenatherum elatius is a principle species in two UK National Vegetation Classification habitat communities: the very widespread MG1 (Arrhenatherum elatius grassland) and the much rarer MG2 (Arrhenatherum elatius - Filipendula ulmaria tall-herb grassland).
