- arrow_drop_downarrow_drop_upCollecting details
Collection 1000310 was collected by C.H. Peck on 5th October 1900 in Westport, New York, UNITED STATES (approx. 44.18°N, 73.43°W, altitude approximately 50 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as woodland with a substrate of fallen soil and litter, 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 Eastern Great Lakes lowland 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).
