Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 16683 was collected by T. Borgen (90.012) on 12th August 1990 in Paamiut/Frederikshåb, at the Navigation School area, 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 tundra with a substrate of boggy 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).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
