bioindicator species

Bioindicator species are organisms used to assess the health of an environment, such as a river or forest. Because they are sensitive to changes in environmental conditions, their presence, absence, or health can reveal problems like pollution or habitat destruction. For example, certain frogs or aquatic insects only thrive in clean water, so if they disappear, it may indicate pollution. Scientists monitor these species to detect early warning signs of environmental issues, helping us to understand and protect ecosystems more effectively.
