- arrow_drop_downarrow_drop_upCollecting details
Collection 9930 was collected by M. Rotheroe, det: H.J. Beker on 11th November 1993 in Les Quennevais,Les Blaches Barques, Jersey, CHANNEL ISLANDS (approx. 49.2°N, 2.1°W, altitude approximately 50 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as coastal dune 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 European Atlantic mixed 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).
