- arrow_drop_downarrow_drop_upCollecting details
Collection 1000529 was collected by L.O. Hilton on 22nd June 1977 in Kalamunda, 100m north west of where Pickering Brook crosses Ashendon Road, Western Australia, AUSTRALIA (approx. 32.0491°S, 116.1955°E, altitude approximately 290 m above sea level - Google maps). The ectomycorrhizal family Myrtaceae (genus Eucalyptus) was present.
The surrounding habitat was described as woodland with a substrate of cadaveric (kangaroo) 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 Southwest Australia woodlands 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).
