In this analysis, we quantified the range loss to forest-dwelling vertebrates that is attributable to demand for agricultural and forestry products by developed countries in 2001-2015.

We used several datasets in this analysis. Data on forest cover and forest loss were sourced from Hansen et al. and publicly available to download online: https://earthenginepartners.appspot.com/science-2013-global-forest/download_v1.7.html. Data on range maps for species were sourced from the IUCN and downloaded from the IUCN’s API (https://www.iucnredlist.org/resources/spatial-data-download) and its partner BirdLife International’s API (http://datazone.birdlife.org/species/requestdis). These datasets are made available for academic research on request, and an API key is necessary for their downloads. We sourced data on land use attribution from Nguyen Tien Hoang and Keiichiro Kanemoto, from their 2021 publication “Mapping the deforestation footprint of nations reveals growing threat to tropical forests.” These data are not publicly available, but the authors kindly provided the data on request.

Code necessary to replicate the analysis can be found in a public repository at: https://github.com/AlexWiebe/Outsourced-Biodiversity-Loss.
