- arrow_drop_downarrow_drop_upCollecting details
Collection 9876 was collected by C.A. Hobart, det: H.J. Beker on 28th October 2003 in Holkham Meals, West Norfolk, ENGLAND (52.971°N, 0.8057°E, altitude approximately 0 m above sea level - Google maps). The ectomycorrhizal families Salicaceae (genus Salix) and Pinaceae (genus Pinus) were present.
The surrounding habitat was described as coniferous dune woodland with a substrate of sandy 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. 13.3: Coastal Sand Dunes.
According to the GPS data the collection was in the Celtic broadleaf 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).
