- arrow_drop_downarrow_drop_upCollecting details
Collection 18253 was collected by H.J. Beker, L. Davies on 27th September 2018 in McClymont Park, near Prince Rupert, British Columbia, CANADA (54.3141°N, 130.3099°W, altitude approximately 30 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Tsuga) was present.
The surrounding habitat was described as boreal, 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. 1.1: Forest – Boreal.
According to the GPS data the collection was in the Central Pacific Northwest coastal 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). Use this webtool to explore the ecoregions visually or see a full list of current ecoregions on Wikipedia. (biome: Temperate Conifer Forests) and Koppen climate code Cfb (Temperate, no dry season, warm summer).
