- arrow_drop_downarrow_drop_upCollecting details
Collection 1000386 was collected by B. Kropp on 19th May 2009 in Tutuila Island, National Park of American Samoa, Tutuila Unit, along Mount Alava Trail, AMERICAN SAMOA (approx. 14.286°S, 170.7139°W, altitude approximately 190 m above sea level - Google maps). The ectomycorrhizal family Fabaceae (genus Intsia) was present.
The surrounding habitat was described as subtropical woodland 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 Samoan tropical moist 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).
