- arrow_drop_downarrow_drop_upCollecting details
Collection 9931 was collected by D.A. Reid, det: H.J. Beker on 8th October 1971 in Graffham, Surrey, ENGLAND (approx. 50.965°N, 0.679°W, altitude approximately 50 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as mixed woodland with a substrate of bare 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 English Lowlands beech 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).
