- arrow_drop_downarrow_drop_upCollecting details
Collection 16049 was collected by T. Clements, D. Fulton (TC-TAC1572) on 25th August 2016 in Coconino County , Arizona, UNITED STATES (approx. 35.5°N, 112°W, altitude approximately 2000 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genera Abies, Picea and Pinus) and Salicaceae (genus Populus) were present.
The surrounding habitat was described as mixed, subalpine woodland, 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 Arizona Mountains 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).
