Ecological resilience refers to an ecosystem’s ability to absorb disturbances, adapt to changes, and recover from shocks while maintaining its core functions and structure. Resilient ecosystems can withstand stressors such as natural disasters, invasive species, habitat fragmentation, and human activities without collapsing or transitioning into a degraded state. High-resilience ecosystems—like wetlands, mangroves, coral reefs, and old-growth forests—demonstrate a capacity to bounce back after events such as floods, fires, or droughts. These systems offer ecological stability, biodiversity protection, and climate regulation, making them vital for both human and planetary health.
