- arrow_drop_downarrow_drop_upCollecting details
Collection 17034 was collected by W.G. McAdoo (BM-BMA209) on 25th October 2010 in S. Pass Road near Sumas, Whatcom County, Washington, UNITED STATES (approx. 48.9602°N, 122.1893°W, altitude approximately 190 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Tsuga) was present.
The surrounding habitat was described as woodland pathside, 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. 1.4: Forest – Temperate.
According to the GPS data the collection was in the North Cascades conifer forests 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).
