- arrow_drop_downarrow_drop_upCollecting details
Collection 13659 was collected by H.J. Beker on 5th October 2010 in Casteldelfino, Piedmont, ITALY (44.5829°N, 7.1107°E, altitude approximately 1140 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) was present.
The surrounding habitat was described as mixed woodland riverside with a substrate of burnt 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 Alps conifer and 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).
