This is what she has written-
Quoting:To introduce vetiver grass into California (or more specifically to the Bay Area) could, in my opinion, be disastrous. Non-native grasses, especially plants of the size of vetiver grass (to 9 feet tall, roots 12 feet long), quickly outcompete the native vegetation and are extremely difficult to eradicate once they have become established. Examples of invasions by two large, non-native grasses are giant reed (Arundo donax) and pampas grass (Cortaderia jubata), both of which have destroyed native habitats and disturbed the ecological balance in wetlands, watercourses, and marshes around San Francisco Bay (see attached pictures). Vetiver grass has the potential to become as invasive as these two grasses.
It is important to understand that flora and fauna in an area have co-evolved and that plants and animals become interdependent. Native animals are dependent on native plants for food and shelter. Plants are at the bottom of the food chain, therefore, if the plant is not "usable" by an animal species, for example a mouse, the animals higher up in the food chain will also disappear - such as the snake and the hawk.
