Negative buffers are 50% of the size of their respective Thiessen polygons. In this case one negative buffer is completely within the protected area boundary and therefore this PA was considered for analysis. All pixels that fell within the protected area shapefile (n = 3) were used to calculate the INDVI. Figure S2 Population densities of African savannah elephants as a function of the log of the area surveyed. Figure S3 Box plot displaying the distribution of savannah elephant population densities as a function of the type of survey performed. Table S1 Spearman correlation coefficient (rho) between the explanatory variable considered.
