Water Crowfoot (Ranunculus aquatilis)
An aquatic member of the buttercup family, with long trailing green foliage and small white flowers, water crowfoot is important in the River Mease. It provides cover, food and habitat for fish, and is a structural feature of river channels. The foliage may modify water flow and promote fine sediment deposition. Water crowfoot needs clean flowing water. Most of the plant dies away during the winter, but a root-like food store survives beneath the mud and forms a new plant in the spring.
