Jubata Grass Inventory: A GIS mapping of 51 jubata grass (Cortaderia jubata) infestations with aspect, slope, soil type, density of stand, associated plant species, and canopy of associated species documented. This study showed that pampas grass infestations occur in a very particular environment along the Big Sur coast: Rock Outcrop-Xerorthents Association (Rc) soil with little or no canopy cover from associated species.
