Rare-Invasive Interactions

In Cascade-Siskiyou, Oregon, low stable invasive cover was observed after low to mod grazing. High grazing translated to lower native abundance. Taeniatherum caput-medusae was the dominant species. Trends suggested that native forb cover may be in decline (Menke and Kaye 2009)
