Rebecca Gilbert. Hokule‘a Program, Washington University in St. Louis. Background. The negative environmental and economic effects of invasive plant species are now widely appreciated. However, just 100 years ago, exotic plant introductions were widely celebrated and were part of the mission of botanical gardens around the world. As a result, an important area of research in conservation biology is to evaluate the invasive potential of plants that occur in botanical gardens. Like most botanical gardens, The Honolulu Botanical Gardens (HBG) historically had unregulated plant introductions. . „But the cardoon (Cynara cardunculus) has a far wider range.: it now occurs in these latitudes on both sides of the Cordillera across the continent. I saw it in unfrequented spots in Chile, Entre Rios, and Banda oriental. In the latter country alone, very many (probably several hundred) square miles are covered with one mass of these prickly plants, and are impenetrable by man or beast. Over the undulating plains, where these great beds occur, nothing else can live. Before their introduction, however, I apprehend the surface supported as in other parts a rank herbage. I doubt whether any case is on record of an invasion of so grand scale of one plant over the aborigines”. An introduction. What is a . native species?.
