Slender false brome is a forest understory and open grassland invader. It can thrive in a variety of soil moisture and is known to occur in full sun or shade.
Threats & Impacts:
One of the first plants to emerge in spring, slender false brome has a competitive advantage over native understory species. Dense, sprawling mats crowd and shade out native herbaceous plants. Fall senescence results in a thick layer of dead thatch material that can increase the risk of wildfires.
Small infestations can be managed by hand pulling of digging prior to seed set. Be sure to bag and solarize all plant material prior to disposal in a landfill. Larger infestations can be treated using a selective foliar spray of glyphosate or triclopyr based herbicide. All management options will require several years of follow up treatment.
