New Plants Move into the Mountains

Swedish Radio’s Science Department reports that the warmer climate is causing major changes in the vegetation in the Swedish mountains.

According to Leif Kullman, professor in geography at Umeå University in northern Sweden, many leafy trees are appearing in areas where previously only evergreens have grown. Not only mountain birches, but also oaks and elms are moving higher up, among the firs and pines.

Kullman says the invasion by trees from lower altitude may also threaten mountain vegetation that grows closer to the ground, such as the high alpine flower, the glacier buttercup.
