Bioindicators serve an important ecological role by providing insight into the health and quality of an ecosystem. These organisms, which can include certain plants, invertebrates, or fish, react to environmental changes and stressors, such as pollutants or habitat alterations. The presence, absence, or abundance of bioindicators can indicate the level of ecosystem integrity and guide conservation efforts. For instance, amphibians are often used as bioindicators because they are sensitive to changes in their environment. Monitoring such species assists in assessing ecosystem health and informs management and restoration strategies.
