Extended Data Fig. 7: Large-mammal abundance in the years before and after Idai.
From: Trait-based sensitivity of large mammals to a catastrophic tropical cyclone
Data are from biennial helicopter-based wildlife surveys, except for wild dog for which we used monitoring data from Gorongosa’s Conservation Program, and represent systematic total counts covering a standardized 193,500-ha area in the core of the park during the late dry season, when canopy cover is lowest. Even the most meticulous counts do not detect all individuals, so data should be interpreted as minimum numbers known alive, but we are otherwise confident in the accuracy of data for these herbivore populations. Lions are particularly difficult to count from the air, and these data substantially underestimate total abundance inferred from ground-based monitoring55, but we consider them a qualitatively reliable index of relative abundance across years.
