As delimited by Polunin (1951), the Arctic is situated on the Northern hemisphere North of (1) a line 50 miles North of the coniferous forest line, (2) the Northern limit of microphanerophytic growth, or (3) the Nordenskjold line, according to the formula V = 9-0,1K. According to this delimination the whole of Greenland belongs to the arctic region. Within the Arctic a subdivision in low- and high-arctic regions is usually recognized. Larsen (1960) marks this transition on the East coast of Greenland near Cape Dalton. Low-arctic East Greenland thus stretches from 60° to 69°30' N. lat. The Angmagssalik area in Southeast Greenland ranges from circa 65° to 67°20' N. lat. Between the Sermilik and the Kangerdlugssuatsiak fjords to the West and East, Denmark Strait to the South and the extensive nunatak area Schweitzerland, merging into the central Greenland ice-cap to the North, the Angmagssalik area in stricter sense (35°45' – 38° W. long., 65°30'-66°20' N. lat.) is the largest ice-free region of low-arctic East Greenland and must therefore, and for its isolated and central situation, be regarded as highly representative.
