Invasive alpine plants are in danger

Due to human factors, exotic plants are invading the high-altitude mountains from the foot of the mountains around the world, which makes the original plants retreat to a higher place and face extinction risk, according to a joint transnational research report published by European researchers recently The joint study, published in the American academic journal ecology and environmental science frontier, said increased traffic, booming tourism and climate change made it possible for alien plants to invade high-altitude mountains This kind of invasion causes the original ecosystem of mountain area to be destroyed, and the plant diversity is in danger According to statistics, the "invaders" attacking high-altitude mountains include at least 1000 kinds of alien plants The Alps, for example, are the most vegetative region in Central Europe, with about 500 endemic plants Due to the rising temperature in recent years, exotic plants are developing rapidly in the Alps, which makes the distribution area of endemic plants shrink According to the plant ecology and Plant Protection Laboratory of the University of Pavia, Italy, from 1950 to now, the lower limit of plant distribution in the Alps has retreated 24 meters to the higher level One of the important reasons for this is that a large number of local infrastructure has been built to facilitate the invasion of foreign plants into the alpine areas The International Commission for the protection of the Alps also recently warned that plants in the Alps are under serious threat If the situation is not improved, 45% of the endemic plants may be extinct by 2100 Christopher traffer, an ecologist at the Federal Institute of technology in Zurich, Switzerland, who coordinated the joint study, warned that the introduction of exotic plants could also affect the living environment of alpine plants For example, the introduction of foreign ornamental plants in the construction of tourism facilities may cause the gradual disappearance of local endemic plants He suggested that the relevant government departments should further improve and strictly implement the laws and regulations on the introduction of foreign plants.
