Alpine plant range shifts

SLF botanists and volunteers recheck Graubünden's 1930s flora one hectare at a time

SLF's Flora Raetica project is resurveying Graubünden's plants on 1,104 one-hectare squares and comparing them with records made in the early 1930s. So far, the evidence that plants are moving uphill comes from one plot near Davos and a treeline estimate from co-leader Christian Rixen.
