Ecological status refers to the condition of an aquatic ecosystem, assessed based on various biological, chemical, and physical indicators. It reflects how well an ecosystem functions and supports its biodiversity, as well as its ability to maintain processes, resist disturbances, and provide services to humans. In the context of water bodies, such as rivers, lakes, and coastal areas, ecological status is often classified into categories such as "high," "good," "moderate," "poor," and "bad." These classifications are based on comparisons with reference conditions, which represent the natural or least-disturbed state of the ecosystem. Each status is given a specific color (high-blue, good-green, moderate-yellow, low-orange, and bad-red). Assessing ecological status is crucial for environmental monitoring, management, and conservation efforts. It provides a comprehensive understanding of the health of ecosystems, guiding actions to protect and restore biodiversity, improve water quality, and ensure the sustainable use of natural resources. Policies such as the European Union's Water Framework Directive (WFD) rely on ecological status assessments to achieve the goal of good ecological status for all water bodies.
