In-Depth Information
We converted biodiversity data for birds [69, 70], mammals [71, 72], and amphib-
ians [73] to raster format and analyzed them in ArcGIS. For birds, we used only the
breeding range for each species.
Size estimates of blocks were calculated using ArcGIS and verifi ed by comparing
to published accounts in government sources.
To calculate the percentage of Ecuadorian and Peruvian Amazon zoned into oil
and gas blocks, we used the data in [74] for the size of the Ecuadorian Amazon (81,000
km 2 ) and in [9] for the size of the Peruvian Amazon (677,048 km 2 ).
We analyzed indigenous territory maps in Peru [75] and Ecuador [R. Sierra, un-
published data] and recorded the number of overlaps with oil and gas blocks.
