  • arrow_drop_downarrow_drop_upCollecting details

    Collection 12747 was collected by J. Horman on 27th October 2008 in Rocky Point Preserve, Long Island, New York, UNITED STATES (40.9402°N, 72.9485°W, altitude approximately 40 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pinus) and Fagaceae (genus Quercus) were present.

    The surrounding habitat was described as mixed woodland with a substrate of sandy 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. 1.4: Forest – Temperate.

    According to the GPS data the collection was in the Atlantic coastal pine barrens 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).
