  • arrow_drop_downarrow_drop_upCollecting details

    Collection 13532 was collected by E. Ohenoja, M.O. Ohenoja (EO-25.8.74.29a) on 25th August 1974 in Churchill, Fort Churchill. At SSW of town, S side of the road connecting Landing Lake Road and the Churchill Rd, just W of the former., Manitoba, CANADA (approx. 58.75°N, 94.0833°W, altitude approximately 20 m above sea level - Google maps). The ectomycorrhizal families Rosaceae (genus Dryas) and Salicaceae (genus Salix) were present.

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

    According to the GPS data the collection was in the Southern Hudson Bay taiga 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).
