- arrow_drop_downarrow_drop_upCollecting details
Collection 12966 was collected by S. Poumarat, G. Corriol (SGP 08 09 58) on 25th September 2008 in Querigut, Foret des Ares (Chemin du lac), Ariege, FRANCE (approx. 42.7047°N, 2.1075°E, altitude approximately 1250 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) was present.
The surrounding habitat was described as subalpine willow thicket with a substrate of boggy, calcareous, mossy 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. 5.3: Wetlands (inland) – Shrub dominated wetlands.
According to the GPS data the collection was in the Pyrenees 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).
