Generally, rivers provide important habitats and serve as feeding and breeding grounds for a wide range of riverine biodiversity that lives in the river as well as in the river-fringing vegetation or river banks. Rivers also form a key component of our environment and landscape. They provide the means for delivering water to every corner of the earth and are vital for healthy waterways.
The riverine biodiversity that is detailed or stressed here are the plant and animal species that live in and along the river. River being the habitat for them indirectly makes them as biological indicators for the health of specific water bodies especially rivers. This is because certain plants as well as animals prefer clean river or maintained river banks, making them as indicators of water stream deterioration due to human activities.
