Dendroclimatic Relationship of Sampling Mountain Birch
Arctic treelines have been used as global indicators of climate change. Study has shown that terrestrial vegetation has migrated up-and-down mountain sides throughout the Holocene. Mountain birch (Betula pubescens subsp.czerepanovii) is the dominant treeline species in northern Sweden. There has bee...

Three global climate models are then used to predict future RWI values. Results indicate that sapling trees RWI correlate with summer temperatures, but does not strongly correlate with precipitation. It is predicted that when compared to mature trees, saplings will not have a consistent response in how they are impacted by climate change due to the differences in factors that influence the establishment of trees.

Arctic treelines have been used as global indicators of climate change. Study has shown that terrestrial vegetation has migrated up-and-down mountain sides throughout the Holocene.
