- arrow_drop_downarrow_drop_upCollecting details
Collection 11018 was collected by M.L. Beker, det: H.J. Beker on 25th July 2005 in Budahraun, ICELAND (64.8127°N, 23.4194°W, altitude approximately 25 m above sea level - Google maps). The ectomycorrhizal families Ericaceae (genus Arctostaphylos) and Betulaceae (genus Betula) were present.
The surrounding habitat was described as boreal, deciduous woodland lavafield with a substrate of calcareous, 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. 1.1: Forest – Boreal.
According to the GPS data the collection was in the Iceland boreal birch forests and alpine tundra 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: Boreal Forests/Taiga) and Koppen climate code Dfc (Cold, no dry season, cold summer).
