Revegetation of an Airstrip and Dirt Roads in Central East Greenland

Revegetation of an airstrip and associated dirt roads on Pingo Pass, central East Greenland (71 48 N, 24 15 W), was studied in 1991, 34 years after their construction and abandonment. Sixty-two of the 103 species occurring on the Pass were found on the study sites. This relatively fast rate of recol...
