  • arrow_drop_downarrow_drop_upCollecting details

    Collection 16772 was collected by A. Kong (3683) on 18th August 2001 in La tinaja, Chihuahua, MEXICO (approx. 28.1548°N, 107.3529°W, altitude approximately 2500 m above sea level - Google maps). No ectomycorrhizal plants were recorded.

    The surrounding habitat was described as montane, subtropical woodland with a substrate of 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. 1.9: Forest – Subtropical/tropical moist montane.

    According to the GPS data the collection was in the Sierra Madre Occidental pine-oak 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).
