Abstract
We use comparable 2005 and 2018 population data to assess threats driving the decline of lion Panthera leo populations, and review information on threats structured by problem tree and root cause analysis. We define 11 threats and rank their severity and prevalence. Two threats emerged as affecting both the number of lion populations and numbers within them: livestock depredation leading to retaliatory killing of lions, and bushmeat poaching leading to prey depletion. Our data do not allow determination of whether any specific threat drives declines faster than others. Of 20 local extirpations, most were associated with armed conflicts as a driver of proximate threats. We discuss the prevalence and severity of proximate threats and their drivers, to identify priorities for more effective conservation of lions, other carnivores and their prey.
Description
SUPPLEMENTARY TABLE 1. Lion populations in Africa identified in a 2005 workshop and in a
2018 reassessment (see text for details), whether armed conflict had affected the population,
whether data were available for both time periods (matching pair) and the main threats
identified. This is a comma separated values file available in the Supplementary materials
section at doi.org/10.1017/S0030605320000253.
