Delta arrowhead (Sagittaria platyphylla) in the Yangtze River: an invasive aquatic plant and the potential ecological consequences.

Abstract

The Yangtze River basin in China has one of the most highest rates of biological invasion of any freshwater ecosystem. As it is also an important agriculture, aquaculture and biodiversity hotspot, it is critical to implement early detection and rapid response, monitoring and control of new invasive species as they are discovered. This is the first report of the presence of the invasive aquatic vascular plant Sagittaria platyphylla in the middle and lower reaches of the Yangtze River. We propose that more research should focus on control of the aquarium trade and wetland restorations.
