The Impact of Armed Conflict on Biodiversity in Protected Areas
Quick fact
During the Cambodian Civil War (1970-1995), tiger populations in some protected areas actually increased because rebels and government forces kept out poachers and developers. However, after the war ended, tiger numbers plummeted as the peace brought an influx of hunters.
Why this is interesting
When war breaks out, we often think of soldiers, not songbirds. Yet some of the most surprising winners and losers of armed conflict are found not on the battlefield, but deep inside the world's national parks.

Understanding The Impact of Armed Conflict on Biodiversity in Protected Areas
Armed conflict is a mega-disturbance that reshapes landscapes and wildlife in contradictory ways. Imagine a forest park suddenly emptied of its usual human visitors—ecotourists, rangers, and loggers. In some ways, that forest might actually become safer for animals: fewer people means less poaching and less habitat destruction. This is why some conflict zones become accidental refuges. But war is not just about absence—it brings military operations, bombings, and the movement of troops, turning parts of the park into a battlefield. Moreover, when people are displaced, they may seek refuge inside protected areas, setting up camps and exploiting resources to survive. So, the impact of conflict on biodiversity in protected areas is a tug-of-war between the absence of normal pressures and the chaos of war itself. The outcome depends on the intensity, duration, and location of the conflict, and on the resilience of the ecosystem.
A deeper explanation
The mechanism behind these varied outcomes lies in a feedback loop: conflict alters human activity, which in turn alters ecological pressures. Direct effects include the immediate destruction of habitats from bombing, fires, and the construction of military infrastructure. Additionally, the use of landmines can render areas uninhabitable for both humans and large animals, creating de facto sanctuaries but also long-term hazards. Indirect effects are equally powerful. When governments are weakened by war, protected areas often lack enforcement, leading to a surge in illegal logging and poaching. The displacement of people into protected areas exacerbates these pressures. Conversely, in regions where conflict reduces overall human presence, wildlife may briefly thrive. However, these gains are often reversed when peace returns, as demobilized soldiers may turn to poaching, and reconstruction leads to new development pressures. Thus, the biodiversity impact of armed conflict is not a simple casualty list; it's a complex, context-dependent dynamic that can either devastate or inadvertently shield ecosystems, with the outcome shaping the future of conservation in these areas.
