Flooding can have a negative effect on wildlife, causing drowning, disease proliferation, and habitat destruction. In 2012, hundreds of animals, including many vulnerable one-horned rhinos (Rhinoceros unicornis), were killed in floods that swamped Kaziranga National Park in the Indian state of Assam. Unpredictable floods can be harmful even to aquatic life. For example, fish can be displaced and their nests destroyed.
