- arrow_drop_downarrow_drop_upCollecting details
Collection 9486 was collected by T. Hering, det: H.J. Beker on 11th November 2003 in Parque Regional del Sureste, road M 311, Rivas Vaciamadrid to Chinchon, km 7, Madrid, SPAIN (approx. 40.3185°N, 3.498°W, altitude approximately 550 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Populus) was present.
The surrounding habitat was described as woodland with a substrate of calcareous, decomposed soil and litter, 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 Iberian sclerophyllous and semi-deciduous 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).
