Vegetation map of northernmost Finland with special reference to subarctic forest limits and natural hazards
The aim of this study has been to provide a better spatial view of the distribution of different forest types and other major vegetation types and of their relationship to the landscape. The study is based on new topographic maps, interpretation of Landsat‑1 imagery, aerial photographs and field co...
