A European introduction, Smooth Brome has been widely used in roadside plantings for erosion control and agriculturally for forage, but has spread beyond that to natural areas where it can be a bad pest, crowding out native species and reducing diversity. Invasive Listing Sources. ... State Lists - This map identifies those states that have this species on their invasive species list or law. We investigated the effects of invasive smooth brome (Bromus inermis) on grassland soil bacterial community structure using massively parallel sequencing of the 16S rRNA gene to determine bacterial community richness, evenness, composition and beta diversity (UniFrac indices) of soils collected along a gradient of smooth brome abundance.

Estimates in the scientific literature of the number of species have ranged from 100 to 400. Although less invasive than Kentucky bluegrass, with which it often occurs and is managed, it is also less responsive to management. Minnesota Department of Natural Resources. The effects of invasive species on the patch dynamics (establishment, growth, and local extinction) of native species are not well studied, owing to the need for relatively fine-scale data on the distribution of species. Habitat: Smooth brome is widely cultivated as an excellent hay an pasture grass, and as a soil cinder along roadsides, eroded banks, etc., throughout Ontario. Smooth Brome, Bromus inermis.

Effective control measures are required for the invasive forage grass smooth brome in native prairie to maintain native prairie diversity and function. Unfortunately Smooth Brome started to invade the area and concern was raised it may reduce the habitat for the Yukon Draba. They’ll eat other invasive grasses too (I watched them working on Kentucky bluegrass this morning, in fact) but if smooth brome is available, they’ll hit that first. inermis var.
