- arrow_drop_downarrow_drop_upCollecting details
Collection 1000252 was collected by R. Kuhner on 14th October 1946 in Avoudrey, Doubs, FRANCE (approx. 47.138°N, 6.435°E, altitude approximately 700 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Abies) was present.
The surrounding habitat was described as coniferous woodland 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 Western European broadleaf 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).
