Aquatic plants control

Abstract

One of the main problems for aquatic environmental management is linked to the excessive important development of some aquatic plants. These plants can be native species favoured by environmental disturbances created by human activities, or exotic ones able to adapt to a large range of sites. Their spreading out in aquatic environments is often requiring a control management. These prolific growths are mainly concerning lakes and wetlands. Some examples from diverse sites are showing their diversity and the needs of adapting control methods to the characteristics of these species, of water-bodies and human activities of these sites. To complete the essential steps of preventive management, allowing to reduce the control activities on aquatic plants to what is just necessary, efforts must be carried on to improve these practices. They should especially insist on the assessment of methods impacts, on a best co-ordination of undertaken actions, on a best circulation of information between all the partners, and on a intensification of a training program of all these actors of aquatic plants regulation practices.
