- arrow_drop_downarrow_drop_upCollecting details
Collection 19415 was collected by N. Ironside on 14th June 2003 in on the property next to Smith's, Manitoulin Co., Robinson Twp., Ontario, CANADA (approx. 45.8°N, 82.7935°W, altitude approximately 180 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Abies) was present.
The surrounding habitat was described as dune 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. 13.3: Coastal Sand Dunes.
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).
