- arrow_drop_downarrow_drop_upCollecting details
Collection 12815 was collected by P.-A. Moreau, P. Jargeat on 21st November 2008 in Toulouse University Campus, Haute Garonne, FRANCE (approx. 43.5648°N, 1.461°E, altitude approximately 160 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Cedrus) was present.
The surrounding habitat was described as mown urban grassland with a substrate of grassy 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. 14.5: Urban Areas.
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). Use this webtool to explore the ecoregions visually or see a full list of current ecoregions on Wikipedia. (biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfa (Temperate, no dry season, hot summer).
