Tree and Shrub Expansion Over the Past 34 Years at the Tree-Line Near Abisko, Sweden
Shrubs and trees are expected to expand in the sub-Arctic due to global warming. Our study was conducted in Abisko, sub-arctic Sweden. We recorded the change in coverage of shrub and tree species over a 32- to 34-year period, in three 50 × 50 m plots; in the alpine-tree-line ecotone. The cover of sh...
