Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 18204 was collected by H.J. Beker, L. Davies on 13th September 2018 in Arctic haven, Ennadai Lake, Nunavut, CANADA (60.7671°N, 101.691°W, altitude approximately 350 m above sea level - Google maps). The ectomycorrhizal family Betulaceae (genus Betula) was present.

    The surrounding habitat was described as boreal woodland lakeside 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. 1.1: Forest – Boreal.

    According to the GPS data the collection was in the Northern Canadian Shield 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).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
