Climate change is causing vegetation shifts in arctic and alpine ecosystems. These changes will affect our ecosystems including all plants and animals and ourselves. One of the first major changes observed is shrub encroachment of the alpine and arctic tundra; a process that is further thought to relate to changes in grazing pressures.

In ECOSHRUB we study the effects of shrub encroachment on vegetation dynamics and the resulting effects on carbon budgets and albedo for alpine tundra. Nine universities and one research institute has joined forces to study the complex processes through experiments in the Central Norwegian Dovrefjell (Dovre Mountains).

Currently three sub-projects are in progress


Funding achieved from:
The Norwegian Research Council (Klimaforsk 23060/E10), Nansenfondet, I.K. Lykkes Fond, and Peder Sather grant program.
