During a guided mountain hike on the Hochgrat (Allgäu), foresters as multipliers of the Citizen Science project BAYSICS showed how interested hikers can record the current tree boundaries with the help of the BAYSICS app and thus contribute to climate research “on their doorstep”.
A team from Bayerischer Rundfunk was there and made this film report that is worth watching:
