State-of-the-art bioengineering technics to control Asian knotweeds

Abstract

Based on the competitive effects of native plants, bioengineering techniques aim both at controlling the development of Asian knotweeds and at restoring a diverse plant community in invaded areas. These methods are appealing to more and more managers. This article focuses on these methods, which mobilize herbaceous or ligneous species, associated sometimes with pre-treatments but always with accompanying measures. After a synthesis on the ecological mechanisms involved, some techniques specifically used to manage Asian knotweeds are described with a focus on riparian habitats. Finally the conclusion raises the question of the importance to share experiences in order to progress in the implementation of bioengineering methods to control knotweeds.
