  • arrow_drop_downarrow_drop_upCollecting details

    Collection 18933 was collected by H. Knudsen (18.296) on 21st August 2018 in bottom of Laksebund, Arsuk Fjord, S, GREENLAND (approx. 61.25°N, 48.08°W, altitude approximately 100 m above sea level - Google maps). No ectomycorrhizal plants were recorded.

    The surrounding habitat was described as arctic tundra, 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. 4.1: Grassland – Tundra.

    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).
