Characterization of Geo-Hydro-Ecological Factors Affecting the Distribution of Endangered Species in Viiankiaapa Mire, a Mineral Exploration Site

摘要

A prominent Cu-Ni-PGE sulphide discovery named Sakatti has been discovered below the Natura 2000 protected Viiankiaapa mire. A thermal infrared survey using an unmanned aerial vehicle was combined with field observations and hydrogeochemical analysis of pore water in the peatland to assess whether endangered species (especially Hamatocaulis vericosus) prefer areas influenced by groundwater or certain geochemical environments. Before planning of the intensive exploration and possible mining activities, it is important to understand the possible association of the mire vegetation with groundwater-surface water interactions, as well as the geochemical features of the local bedrock.
