- arrow_drop_downarrow_drop_upCollecting details
Collection 16782 was collected by A. Montoya-Esquivel (E1824) on 22nd July 2004 in La Malintzi, Ladera Este, Canada Grande, Tlaxcala, MEXICO (approx. 19.1989°N, 97.9694°W, altitude approximately 2900 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 Trans-Mexican Volcanic Belt 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).
