- arrow_drop_downarrow_drop_upCollecting details
Collection 15563 was collected by H.J. Beker on 15th September 2016 in Terskol Valley, Karachay-Balkar, RUSSIAN FEDERATION (43.2482°N, 42.5262°E, altitude approximately 2075 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Pinus) was present.
The surrounding habitat was described as coniferous, subalpine woodland 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. 1.1: Forest – Boreal.
According to the GPS data the collection was in the Caucasus 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).
