By studying 57 experimental plantations, the national project wants to determine which species will best withstand climate change.  Visit the southernmost point of the country They are too cute: small maples, mini-oaks, firs, pines... On a plot of land with an area of approximately 3800 m², young ones are planted, barely 2 years old, with a height of between 10 and 40 cm. The perimeter is secured by a trellis 2.50 m high, against the entry of deer and wild game. We are in Losona, Ticino, 250 meters above sea level. Gottardo Pestalozzi, head of communications at the Federal Institute for Forest, Snow and Landscape Research (WSL), takes us on a tour of the lowest site among the 57 national Experimental Plantations of Future Species project run by the Swiss organization.
