- arrow_drop_downarrow_drop_upCollecting details
Collection 17374 was collected by E. Grilli, G. Pacioni, U. Marulli (EG-990729.05), det: E. Grilli on 29th July 1999 in Mt. Aquila, Isola del Gran Sasso d’Italia (TE), Abruzzo, ITALY (approx. 42.4591°N, 13.5743°E, altitude approximately 2100 m above sea level - Google maps). The ectomycorrhizal family Cistaceae (genus Helianthemum) was present.
The surrounding habitat was described as alpine shrubland pastureland 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. 5.11: Wetlands (inland) – Alpine wetlands (inc. temporary waters from snowmelt).
According to the GPS data the collection was in the Appenine deciduous montane 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).
