Invasive plants are detrimental to natural ecosystem services and they reduce biodiversity. Red brome and medusahead are two abundant grass species that are much more invasive here in California than in their Mediterranean countries of origin. This is likely because they left behind their natural enemies, such as root and shoot pathogens, when they left their native habitat. UCCE researchers are trying to understand the effect of above- and below-ground changes in an effort to find a way to control these invasive grasses. Managers and owners of lands affected by the two highly invasive species will benefit from this research.
