- arrow_drop_downarrow_drop_upCollecting details
Collection 1000297 was collected by R.M. Robinson, R.H. Smith on 23rd June 2005 in Plot FC34. Stockyard Forest Block, 3km E of Boundary Road, on N side of Winooka Road, Western Australia, AUSTRALIA (33.1392°S, 116.4289°E, altitude approximately 340 m above sea level - Google maps). The ectomycorrhizal family Myrtaceae (genus Eucalyptus) was present.
The surrounding habitat was described as mixed woodland with a substrate of 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 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).
