The forests they will not be able to keep up with the very rapid ones changes brought by the current climatic crisis: the study published in the magazine Science and led by the American Syracuse University indicates this, which shows how trees need at least 100-200 years For move their populations In response to temperature variations. According to researchers, it could therefore serve greater intervention by man: the assisted migrationwhich consists in planting trees from warmer climates in places traditionally coldercould be an effective tool to help these ecosystems.
The forests are able to adapt to climate change, moving south in case of colder temperatures or north in case of a heating. But the global warming in progress And too fast Compared to their adaptation times, which are centuries.
“There is one discrepancy between the times With which forests change naturally and what is happening today with climate change “, says David Fastovich, the first author of the study:” The changes at the population level will not be quick enough to preserve the forests we care about “.
The researchers managed to estimate these timing by examining the pollen data from carrots of lake sediments, which have made it possible to trace back to 600 thousand years ago.
“With this new technique – comments Fastovich – we can understand how dispersion and demographic variations interact with each other and how they change a forest over the decades and centuries, and even on longer time stairs: this had never been done before”.
