Table 1. Threat layers and respective data sources.
Key threats | Indicators | Spatial layers | Impact at population level |
---|---|---|---|
Overexploitation *▪ | Population density, human land use and infrastructure | WCS and CIESIN/Columbia University. 2005. Last of the Wild Project, Version 2, 2005. Global Human Footprint ● | Fragments populations, reduces tree density |
Overgrazing *▪ | Cattle, goat and sheep density per area | Gridded Livestock of the World v2.0, 2014, FAO and ILRI ● | Inhibits natural regeneration |
Fire *▪ | Fire frequency per unit area | NASA Fire Information for Resource Management System (FIRMS), 2012. MODIS Active Fire Detections 2007–2012 ● | Reduces tree density, inhibits natural regeneration |
Cotton production **▪ | Cotton growing area as percentage of land area | Ministry Report 2010 map and regional cotton production statistics ● | Eliminates natural populations |
Mining **▪ | Presence of mining sites, occurrences and prospects | Mineral Resources Data System (MRDS) of the U.S. Geological Survey 2005 + Ministry Report 2010 map ●● | Eliminates natural populations; opens roads |
Climate change *▪▪ | Predicted absence, presence or presence under novel regional climatic conditions of suitable habitat | Bioclimatic dataset under future conditions: Downscaled GCMs from CMIP5 for 2055, RCP 4.5 and 8.5 scenarios ●● | Reduces flowering and fruit set, damages healthy individuals, promotes invasive species |
