in search of the tree line
Did you know that trees move?... Well, tree species move when local conditions change. It is the case in the Alps where the average temperature has increased by more than 2oC in the past 30 years alone.
As it gets warmer, trees are able to survive higher up and hence the highest altitude at which trees can live (the tree line) climbs as well. Today in the Alps, it stands at between 1800m and 2200m, several hundred meters higher than 30 years ago.
This month, I am going to ride to the tree line. Starting in Neuchâtel, I am going to ride about 100km to get to the altitude, and then ride back, which is going to be a bit longer.
