A riverine habitat is significant because it serves as a crucial ecosystem that supports diverse flora and fauna. These habitats provide essential resources like food, shelter, and breeding grounds for various organisms, including fish, birds, and amphibians. Riverine ecosystems also play a critical role in water purification, nutrient cycling, and flood control. They help maintain local biodiversity and contribute to the overall health of the environment. Additionally, riverine habitats are vital for human communities, offering recreational opportunities and resources for agriculture and fisheries, highlighting their ecological and economic importance.
