<i>Arrhenatherum elatius</i> (L.) J. Presl & C. Presl in the Bryansk Region
The distribution of Arrhenatherum elatius (L.) J. Presl & C. Presl in the Bryansk Region was estimated. A. elatius was noted in 28 of 215 examined cells. A. elatius is an alien species, neophyte. Recently, its distribution has intensified. A. elatius is found along slopes of railroads, roadsides of field and highways, in meadows and deposits, in forest belts and forest edges. Monodominant communities in anthropogenic and natural habitats are formed. A. elatius is an invasive species actively spreading and naturalizing in disturbed, semi-natural and natural habitats. A. elatius might have been brought to the territory of the Sevsky district of the Bryansk Region during the military operations in 1942-1943. This is evidenced by the nature of the distribution of A. elatius .
