Abstract
Fredskild, Bent & Sune Holt: The West Greenland “Greens”—Favourite Caribou Summer Grazing Areas and Late Holocene Climatic Changes. Geografisk Tidsskrift 93:30–38. Copenhagen 1993. Though covering less than 2% of the area around Kangerlussuaq, Midwest Greenland, small “greens” of non-flowering Poa pratensis are used as feeding sites by caribou, 25% of the time during summer, peaking at 78% in the post-calving period. Analyses of pollen content and chemical composition in soil profiles confirm the hypothesis of their formation being a result of grazing. The original vegetation types were Salix glauca scrubs or grassy Betula nana heaths. Indications of earlier grazing periods are seen in some profiles. Besides, a climatically caused change to more humid vegetation is seen in all profiles. This event has been 14C dated at 1690 ± 75 B P. in one profile. Due to a recent pronounced decline in the caribou population, the greens are now changing with Poa pratensis flowering vigorously as a result of little or no ...
