- arrow_drop_downarrow_drop_upCollecting details
Collection 1000012 was collected by H.S.C. Huijsman on 8th October 1960 in Ste Baume, FRANCE (approx. 44.03°N, 4.68°E, altitude approximately 155 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as deciduous woodland, 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 Northeast Spain and Southern France Mediterranean 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).
