- arrow_drop_downarrow_drop_upCollecting details
Collection 1000145 was collected by J. Vila, X. Llimona on 8th January 2008 in el Port de la Selva, sa Perafita, Girona, SPAIN (approx. 42.299°N, 3.233°E, altitude approximately 245 m above sea level - Google maps). The ectomycorrhizal family Cistaceae (genus Cistus) was present.
The surrounding habitat was described as Mediterranean maquis 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. 3.8: Shrubland – Mediterranean-type shrubby vegetation.
According to the GPS data the collection was in the Northeast Spain and Southern France Mediterranean 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).
