A study published recently in the scientific journal Ecography says that as the global climate warms, the forest vegetation in the northern forests will migrate further north,media reported. To escape global warming, the north’s own species will be less numerous as a result of migration, and large numbers of species are likely to occur in the northern regions, where southern species have been rarely seen before.
The study predicts the fate of the 25 species of under-forest plants common lying in Finland in the coming decades. Among them, 15 species of underforest plants, such as dwarf shrubs, herbs, grasses, moss and lichens, have a strong response to temperature and are expected to move northwards at a rate of 6 to 8 km per year. The number of the other 10 species does not seem to be affected by temperature. It can be speculated that global warming may have no effect on these species.
“Some species currently distributed in southern Finland, such as grass, false bellorchids, polarisand and moss, are likely to reach the northern region, although they were rare in the north in the 1980s,” said researcher Sarah Villen Perez. “
The study also predicts that the number of species common in the northern forests will continue to decline, and that if there is enough land, they will move further northwards, but that possibility has been cut off by the Arctic Ocean.
The study only analyzed the effects of global warming on vegetation in the forest, but did not take into account other factors, such as precipitation, soil, light, or tree types.
The scientists also stressed that they were only predicting potential changes in species abundance, and that their confirmation would depend on the species’ ability to cope with climate change in situ and its own ability to spread.
