- arrow_drop_downarrow_drop_upCollecting details
Collection 16104 was collected by N. Siegel (1291) on 28th October 2014 in Heart O'hills Campground, Olympic National Park, Washington, UNITED STATES (approx. 48.0356°N, 123.4241°W, altitude approximately 550 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genera Pseudotsuga and Tsuga) was present.
The surrounding habitat was described as coniferous woodland 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. 1.4: Forest – Temperate.
According to the GPS data the collection was in the Puget lowland 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).
