Top predators can influence plant communities indirectly by altering herbivore behavior.
In ecosystems where apex predators decline, herbivore populations can increase or alter distribution patterns. Without predation pressure, species such as deer and wild boar may expand into previously risky habitats. Elevated browsing pressure can suppress young tree growth and alter understory vegetation. Such shifts have been documented in multiple predator-removal scenarios globally. The South China tiger historically regulated ungulate numbers across its range. Its disappearance likely reduced this top-down control. Predator absence can thus amplify herbivore ecological influence.

Herbivore surges can reshape forest composition over time. Increased grazing intensity may favor certain plant species while suppressing others. Changes in vegetation affect insects, birds, and small mammals dependent on specific plant structures. What begins as predator loss cascades into community-level reorganization. These dynamics unfold gradually but persistently.
Restoring a predator can recalibrate herbivore behavior through both direct predation and fear effects. However, decades of predator absence may entrench new ecological baselines. The South China tiger’s decline therefore represents more than species scarcity; it alters energy flow through ecosystems. Managing such shifts requires integrated approaches beyond simple species protection. Apex predators function as regulators of ecological tempo.
