- arrow_drop_downarrow_drop_upCollecting details
Collection 18050 was collected by H.J. Beker, L. Davies on 3rd September 2018 in Five Finger Rapids Rest Area, Klondyke Highway North, Yukon, CANADA (62.273°N, 136.3429°W, altitude approximately 585 m above sea level - Google maps). The ectomycorrhizal families Salicaceae (genera Populus and Salix) and Pinaceae (genus Picea) were present.
The surrounding habitat was described as boreal woodland roadside with a substrate of grassy, 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. 1.1: Forest – Boreal.
According to the GPS data the collection was in the Watson Highlands 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).
