- arrow_drop_downarrow_drop_upCollecting details
Collection 1000388 was collected by A. Bresinsky, B. Wittman-Bresinsky (6119) on 23rd May 1995 in Mount Koghis, Dumbea, Province Sud, on soil on pathside, near Gleichenia and Myrtaceae in tropical rainforest, NEW CALEDONIA (approx. 22.1778°S, 166.5068°E, altitude approximately 470 m above sea level - Google maps). The ectomycorrhizal family Myrtaceae (genus Myrtaceae) was present.
The surrounding habitat was described as subtropical woodland pathside with a substrate of 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. 1.5: Forest – Subtropical/tropical dry.
According to the GPS data the collection was in the New Caledonia 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).
