- arrow_drop_downarrow_drop_upCollecting details
Collection 16668 was collected by T. Borgen (83.035) on 31st August 1983 in Paamiut/Frederikshåb, Peters Fjeld, S, GREENLAND (approx. 62.01°N, 49.4°W, altitude approximately 10 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) was present.
The surrounding habitat was described as arctic fenland with a substrate of boggy, mossy soil, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 5.10: Wetlands (inland) – Tundra wetlands (inc. pools and temporary waters from snowmelt).
According to the GPS data the collection was in the Koppen climate code ET (Polar, tundra).
