🌳 Can we help Swedish forests move north before climate change outpaces them?
Trees have always adapted to shifting climates, but they migrate over centuries, and climate change is happening in decades. That mismatch is at the heart of ANAFOR, a new research project at Southern Swedish Forest Research Centre, testing whether "assisted migration" can help Swedish forests keep up.
PhD student Samuel Aspalter and colleagues are planting eight broadleaved tree species across 20 experimental plots, from Eslöv in the south to Vindeln in the north, spanning a huge climate gradient to see how far these species can be pushed before conditions become limiting.
"Our question is essentially: can we move broadleaved tree species from Central Europe and southern Sweden further north to help forests adapt to climate change?" Aspalter says.
The trial establishment was successful – all plots are setup and many seedlings leafed out within two weeks of planting. But the science raises further open questions: could some species become invasive? Could trees that look healthy today struggle later under drought or extreme cold?
