This archive contains information for *SF2.2 Flooded mines and other voids*, a ecosystem functional group (EFG, level 3) of the IUCN Global Ecosystem Typology (https://global-ecosystems.org/).

General notes on maps:
======================

The maps show areas of the world containing major or minor occurrences of *SF2.2 Flooded mines and other voids*. Minor occurrences are areas where an EFG is scattered in patches within matrices of others or where they occur in substantial areas but only within a segment of a larger region.

The maps were designed to be indicative of global distribution patterns and are not intended to represent fine-scale patterns. Given bounds of resolution and accuracy of source data, the maps should be used to query which EFG are likely to occur within areas, rather than which occur at particular point locations.

Methods for this map:
=====================

Point records of flooded mines were compiled from public databases (https://www.unexmin.eu/the-european-inventory-of-flooded-mines-is-now-online/), an internet search for "flooded mines" and locations of deep mines inferred from world mineral resources spatial data (USGS: https://mrdata.usgs.gov/). Terrestrial ecoregions (Dinerstein et al. 2017) with concentrations of these records were selected to represent an indicative global distribution of flooded mines at 30 arc seconds spatial resolution.
