  • arrow_drop_downarrow_drop_upCollecting details

    Collection 12418 was collected by H. Knudsen (90.366), det: J. Vesterholt on 15th August 1990 in Tjumenskaja, northern urals, Oktjabrskij, ca. 10km N of Labytnangi, Tyumen, RUSSIAN FEDERATION (approx. 66.33°N, 65°E, altitude approximately 55 m above sea level - Google maps).

    The surrounding habitat was described as arctic tundra 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 West Siberian 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).
