Open tundra persist, but arctic features decline—Vegetation changes in the warming Fennoscandian tundra
Abstract In the forest‐tundra ecotone of the North Fennoscandian inland, summer and winter temperatures have increased by two to three centigrades since 1965, which is expected to result in major vegetation changes. To document the expected expansion of woodlands and scrublands and its impact on the...
