This dataset focuses on the Tropical Andes region of Colombia, Peru, Ecuador, and Bolivia. We demonstrate indicators in the Tropical Andes using both potential (pre-industrial) and recent (~2010) distribution maps of terrestrial ecosystem types. We measure long-term ecosystem loss, representation of ecosystem types within current protected areas, and quantify the additional representation offered by protecting Key Biodiversity Areas. The mapped pixel resolution is 270 m.

Natural terrestrial ecosystem types were defined at the macrogroup level of the International Vegetation Classification (IVC) for both “potential” (i.e., pre-industrial land use) and “recent” distribution for IVC macrogroups. The “potential distribution” includes biophysical conditions where each type might occur today had there not been any prior intensive human intervention (i.e., since circa 1500). “Recent” distribution then accounts for those areas of intensive intervention and conversion, as of approximately 2010. The long term loss in extent for each ecosystem type was calculated by determining the percentage loss between potential and current extent. The proportions of each macrogroup (recent distributions) occurring within the World Database of Proteaced Areas (WDPA) was calculated. We then calculated the additional proportions of each IVC macrogroup that could be secured through identified Key Biodiversity Areas (KBAs). For applications to continental or global analysis, we rolled up results to the IVC formation level.

Ecosystems. Scope: Ecosystems at the macrogroup level (Level 5) of the International Vegetation Classification Hierarchy (IVC).
Historical loss per ecosystem
The extent of loss for each vegetation macrogroup was calculated by subtracting the “recent” (ca. 2010) extent from the pre-industrial, or “potential” extent and dividing by the "potential" extent.
Proportion of historical loss of ecosystem extent
Ecosystem within protected areas (WDPA)
To calculate the proportion of each macrogroup in existing protected areas, we assessed recent distributions occurring within natural protected areas from the World Database of Protected Areas (WDPA).
Proportion of ecosystem extent within protected areas
Ecosystem within protected areas (WDPA) and Key Biodiversity Areas (KBA)
We calculated the additional proportions in addition to protected areas of each macrogroup (based on the recent extent) that could be protected through identified Key Biodiversity Areas within the Tropical Andes countries.
