- arrow_drop_downarrow_drop_upCollecting details
Collection 16694 was collected by H. Knudsen, det: T. Borgen (16.086G) on 8th August 2016 in Kangerlussuaq, Ammaloortup Nunaa west of Lake Ferguson, W, GREENLAND (approx. 66.9963°N, 50.6145°W, altitude approximately 275 m above sea level - Google maps). The ectomycorrhizal families Salicaceae (genus Salix) and Betulaceae (genus Betula) were present.
The surrounding habitat was described as arctic tundra streamside 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 Kalaallit Nunaat Arctic steppe WWF ecoregion The World Wildlife Fund (WWF) have divided the world into 867 terrestrial ecoregions. The ecoregion here is estimated by mapping from the GPS coordinates of the collection using data made available by Dinerstein et al (2017).
