Slender false brome - (brachypodium sylvaticum)
|
What is slender false brome?
Slender false brome is a State Listed B invasive species, native to North Africa and Eurasia. It is a perennial bunchgrass most commonly found in dry woodlands, but may also grow in open areas. The tall, tufted grass may grow up to 3 feet high and displays a nodding growth habit in both it's blades and flowers. The blades are broad and flat with hairy edges, and may range from dark green to bright yellow-green in color. Because this species may be difficult to distinguish from other grasses, we recommend contacting our noxious weeds program staff for positive identification. |
Why is slender false brome a problem?
Being highly shade and drought tolerant, slender false brome can quickly outcompete native plants and establish itself as the dominant species in forest understories. It acts as excellent cover for rodents, often leading to increased populations, which in combination with the suffocating nature of established false brome thickets can severely restrict the recruitment of young native trees and shrubs, as any seedlings which manage to establish themselves in the dense grass will often be eaten by the increased rodent population. Slender false brome may also be toxic to livestock, especially sheep.

Controlling slender false brome
Small patches of slender false brome can effectively be controlled by hand-pulling before patches become established. This is best done in April and May, when the grass has not yet gone to seed and early spring rains moisten the soil, allowing for the weak root system to easily be dislodged. Hand-pulled patches should be monitored in the following years for signs of resprouting.
Larger patches, however, are most effectively treated through chemical means. Early summer through mid-fall is the best time for herbicide treatment, and mowing false brome patches each year in June before seeds are produced can reduce the overall amount of herbicide needed by preventing the grass from re-germinating after treatment. For advice or assistance in controlling slender false brome infestations, or to report an infestation, please contact the Lincoln Soil and Water Conservation District by phone or email.
