It has long been convinced that mistletoe grew in Switzerland than in the regions with lower altitude 1000 meters above the level of the sea.
A scientist from the Federal Research Institute for Forest, Snow and Landscape Research (WSL) has yet found copies of mistletoe pine at altitudes of up to 1500 meters. This is a direct consequence of global warming. The climate has warmed considerably during the previous century. In Switzerland, the increase in temperature then was much more marked than the world average: only in the last year 30, the temperatures have increased by 1,5 degrees in the country. In recent years 100, altitude limit of the distribution area of pine mistletoe has increased at least 250 meters on average. This is apparent from a comparison with a study effected in 1910.
