What factors determine the ecological health of a wetland?

The ecological health of a wetland is fundamentally influenced by several key factors, which include water quality, biodiversity, hydrologic regime, and the presence of invasive species.

Water quality is crucial in determining the health of a wetland, as it affects the organisms that live there. Factors such as pH, nutrient levels, and the presence of pollutants can significantly impact both plant and animal life.

Biodiversity, or the variety of species present, is a strong indicator of ecological health. A diverse ecosystem is typically more resilient and better able to withstand environmental stresses. In wetlands, the presence of a wide range of species can promote a balanced food web and enable proper nutrient cycling.

The hydrologic regime, involving the patterns of water flow, is essential as it influences wetland structure, nutrient distribution, and habitat availability. Changes in water levels and flow can affect the overall wetland ecosystem, impacting everything from plant growth to the animals that rely on these habitats.

The presence of invasive species can pose a significant threat to wetland health. Invasive species often compete with native flora and fauna for resources, potentially leading to declines in native populations and overall ecosystem functioning.

While other factors like soil type, nearby urban development, and seasonal patterns may play
