  • arrow_drop_downarrow_drop_upCollecting details

    Collection 13570 was collected by on 4th August 1974 in N.W.T. District of Franklin. Repulse Bay. About 2km ESE of the settlement, SE shore of the promomtory opposite to Naujasiti at SW side of the channel from the mouth of Nauja Fiord., Nunavut, CANADA (approx. 66.52°N, 86.22°W, altitude approximately 25 m above sea level - Google maps). The ectomycorrhizal families Salicaceae (genus Salix) and Rosaceae (genus Dryas) were present.

    The surrounding habitat was described as arctic heathland with a substrate of 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. 4.1: Grassland – Tundra.

    According to the GPS data the collection was in the Canadian Middle Arctic Tundra 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).
