Invasive plants – what else?

The migration of plants around the globe is essential for our life. Globalization of human activities disturb normal plant migration. Plants and other live forms from other continents do adapt to their new environments. If they do not find enemies there, they might become invasive and disturb the balance of the biodiversity. Plant invasions often depend on the intensity of land use. Since men cultivate land, weeds do exist and control methods must be adapted to them. The society should accept the introduction of appropriate methods to control the weed. Small specialized groups could develop adapted control strategies after existing restrictions for control have been adapted. Solved problems (ragweed) motivate to courageously tackle existing problems (Japanese knotweed) and future problems (yellow nutsedge).
