Percentage of specimens which fell into the SDTF biome compared to the two other South American dry biomes, savannas (mainly Cerrado in our analysis) and the Chaco.

1 Most specimens fall into agricultural land, and if these areas are considered as degraded SDTF, 62.7% of specimens fall into SDTF. This is likely an overestimation as part of the agricultural land could be degraded savannas or Chaco.
