- arrow_drop_downarrow_drop_upCollecting details
Collection 1000105 was collected by R. Maire on 26th November 1911 in Chrea, ALGERIA (approx. 36.43°N, 2.87°E, altitude approximately 1500 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Cedrus) was present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Mediterranean woodlands and 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).
