An ecological assessment tool is a method or instrument used to evaluate the health and quality of ecosystems. These tools can include indices, models, and indicators that measure various ecological parameters, such as biodiversity, habitat quality, and the presence of pollutants. By assessing these factors, researchers can monitor ecosystem changes, identify significant impacts from human activities, and guide conservation efforts. These assessments are crucial for informing environmental policy, resource management, and sustainable development to ensure the protection of natural habitats and biodiversity.
