- arrow_drop_downarrow_drop_upCollecting details
Collection 12582 was collected by E. Horak on 14th August 2001 in Sawatch Range, Twin Lakes, Independence Pass N, Colorado, UNITED STATES (approx. 39.0918°N, 106.3693°W, altitude approximately 3750 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) was present.
The surrounding habitat was described as alpine meadow, 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. 5.11: Wetlands (inland) – Alpine wetlands (inc. temporary waters from snowmelt).
According to the GPS data the collection was in the Colorado Rockies 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).
