- arrow_drop_downarrow_drop_upCollecting details
Collection 1000065 was collected by G. Bruchet on 11th September 1969 in Lac des Assiettes,Col de la Vanoise, Savoie, FRANCE (approx. 45.389°N, 6.792°E, altitude approximately 2500 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) was present.
The surrounding habitat was described as alpine meadow with a substrate of acidic 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. 5.11: Wetlands (inland) – Alpine wetlands (inc. temporary waters from snowmelt).
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).
