  • arrow_drop_downarrow_drop_upCollecting details

    Collection 1000098 was collected by R. Maire in September 1907 in Foret de Haye, Nancy, Meurthe-et-Moselle, FRANCE (48.6833°N, 6.1833°E, altitude approximately 225 m above sea level - Google maps). No ectomycorrhizal plants were recorded.

    The surrounding habitat was described as 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).

(biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfb (Temperate, no dry season, warm summer).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
