The relationship between herd mortality rate (percent) and the intensity of drought. This is based on the 2005 standardized anomalies (See Figure 2), for four sites. The regression line was fitted through three sites; discarding Kitengela which had unexpectedly high mortality. The shaded band at the bottom right reflects the range of mortality rates in non-drought years (Bekure, et al; 1991). M, Mara; A, Amboseli; S, Simanjiro; and K, Kitengela.
