Pollen assemblage–plant community relationships on the Storbreen glacier foreland, Jotunheimen Mountains, southern Norway
SUMMARY Present‐day pollen assemblages from 38 sites within differing but closely juxtaposed plant communities from the Storbreen glacier foreland in southern Norway, provide evidence for the degree to which these plant communities can be characterized by distinctive pollen assemblages.
