The Indiana Dunes is an area of land beside Lake Michigan, in the State of Indiana, USA. It includes the Indiana Dunes National Lakeshore and the Indiana Dunes State Park. This article is about non-native plant species, specifically the invasive species which have colonized that area. Invasive plants are those plants that aggressively spread throughout an area and out-compete other plant species, normally those that are native to the area. Invasive plant species can have, and have had, several negative impacts: # Some of these plants can overgrow trails and roads, # Some can entangle bike chains, e.g. knapweed # They can displace the variety of flowering plants, substituting a monoculture # They can introduce toxins into the environment, e.g. the sap of the leafy spurge # In some cases they have spines or thorns, e.g. thistles # Some invasive aquatic plants can smoother ponds, killing fish # Some invasive plants can create navigation barriers for small boats ==Plants of special interest== *Purple Loosestrife – establishes a monoculture, reducing the variety of wildlife. 〔 *Bush Honeysuckles – prevents regeneration of woody plants and herbs, reducing bird habitat. 〔 *Glossy Buckthorn – prevents regeneration of woody plants, slowly destroying forests. 〔 *Garlic Mustard – alters the chemistry of the soil to kill other seeds, creating a monoculture. 〔 *Asian Bittersweet – this vine can kill or damage trees and shrubs. 〔 *Crown Vetch – alters the soil chemistry and pushes out the variety of other plants. 〔 *Japanese Knotweed – tolerates floods and drought, creates a monoculture. 〔 *Spotted Knapweed – releases toxins into the soil to poison its competition. 〔 *Common Reed – this introduced non-native species aggressively pushes the native species and other aquatic plants out of the ecosystem. 〔 *Canada Thistle – successfully competes for space in prairies, savannas and dunes. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of invasive plant species in the Indiana Dunes」の詳細全文を読む スポンサード リンク
