- arrow_drop_downarrow_drop_upCollecting details
Collection 1000313 was collected by A.H. Smith (17096) on 21st September 1941 in Clallam, Mt Angeles, Olympic National Park, Washington, UNITED STATES (approx. 47.9955°N, 123.4653°W, altitude approximately 1950 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as boreal woodland, 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 British Columbia coastal 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).
