- arrow_drop_downarrow_drop_upCollecting details
Collection 20409 was collected by P.I. Forster (PIF28455) on 1st March 2002 in Koombooloomba Sate Forest 605, track to Lodges Milloff Tully Falls - Culpa Road, Queensland, AUSTRALIA (approx. 17.8283°S, 145.5628°E, altitude approximately 720 m above sea level - Google maps). The ectomycorrhizal families Myrtaceae (genus Eucalyptus) and Casuarinaceae (genus Allocasuarina) were present.
The surrounding habitat was described as woodland clearing with a substrate of cadaveric (cow) 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 Queensland tropical rain 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).
