mappingAS: Spatial Metrics and Habitat Conversion for Extinction Risk Assessment

A spatial analytical framework for preliminary species extinction-risk screening following the IUCN Red List Criterion B guidelines. From occurrence points it computes the Extent of Occurrence (EOO) and Area of Occupancy (AOO) on a data-centred equal-area projection, assigns provisional Criterion B categories, and integrates 'MapBiomas' land-use/land-cover data to quantify the proportion of anthropogenic conversion versus remaining natural habitat within each range metric, with per-class breakdowns and land-cover time series. Several 'MapBiomas' initiatives are supported through one standardised legend - 'MapBiomas' Brazil, the Pan-Amazon / Amazonia collection (RAISG), Colombia, Argentina, Bolivia, Chile, Ecuador, Peru, Venezuela, Paraguay and Uruguay - so a species anywhere these products cover can be screened as readily as a Brazilian one. For ranges outside 'MapBiomas' coverage it can fall back to the global 'Esri' / 'Impact Observatory' 10 m annual land cover derived from 'Sentinel-2' (the product behind the 'ArcGIS' Living Atlas Land Cover Explorer), so a species anywhere on Earth can be screened. It also integrates 'MapBiomas' Fire to compute burned-area metrics and fire time series, and quantifies the overlap of the range with protected areas from the global World Database on Protected Areas (WDPA). 'MapBiomas' data are read either locally over the network via 'GDAL' '/vsicurl/' (no 'Google Earth Engine' account required) or server-side through 'Google Earth Engine' (GEE) for large-scale assessments. Outputs include interactive and publication ready maps and charts, spatial (shapefile/'GeoPackage') and raster exports, and a written assessment report (HTML, text or Word). An interactive 'shiny' application ties the whole workflow together for reproducible conservation planning.
