Warfare and wildlife declines in Africa's protected areas

Area of Science:

• Ecology
• Conservation Biology
• Wildlife Management

Background:

• Large-mammal populations are vital for ecosystem health, but face global declines.
• Understanding population decline drivers is essential for effective conservation.
• The impact of armed conflict on wildlife populations remains uncertain.

Purpose of the Study:

• To quantify the effect of armed conflict on large herbivore population trends in African protected areas.
• To identify conflict frequency as a predictor of wildlife population declines.
• To inform conservation strategies in conflict-affected regions.

Main Methods:

• Analysis of large herbivore population trends in 71% of African protected areas from 1946-2010.
• Statistical modeling to assess the correlation between conflict frequency and population changes.
• Comparison of population trajectories under varying levels of conflict and other environmental factors.

Main Results:

• Conflict frequency was the most significant predictor of wildlife population trends.
• Population declines were observed with even slight increases in conflict frequency.
• Populations were stable in peacetime but declined significantly with conflict, though total collapse was infrequent.
• Human population density showed a positive correlation with wildlife trajectories in recent years.

Conclusions:

• Armed conflict poses a substantial threat to large herbivore populations in African protected areas.
• Sustained conservation efforts in conflict zones and rapid post-ceasefire interventions are vital.
• Conservation planning must account for the impact of conflict to prevent species declines and extinctions.
