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.
