La crassule des e´tangs (Crassula helmsii) est une plante invasive (ou exotique envahissante) qui repre´sente un risque environnemental pour les milieux aquatiques en Belgique et, plus globalement, en Europe. Pour controˆler cette espe`ce, les acteurs de terrain disposent d’une litte´rature a priori abondante, ainsi que de plusieurs bases de donne´es relatives a` sa distribution spatiale. Néanmoins, les gestionnaires peuvent vite se sentir de´sarme´s, d’une part par le manque de clarte´ sur les moyens a` mettre en oeuvre afin d’endiguer la propagation de l’espe`ce et, d’autre part, par le manque d’exhaustivite´ des bases de donne´es. S’ajoute a` cela une insuffisance de litte´rature sur les vecteurs de dissémination a` travers les paysages. [less ▲]

Japanese knotweed Fallopia japonica is an extremely abundant invasive plant in Belgium and surrounding countries. To date, no eradication method is available for managers facing the invasion of this rhizomatous plant. We tested different chemical herbicides and two application methods (spraying and stem injection), as well as mechanical treatments, on Fallopia clones throughout southern Belgium. The tested methods were selected to be potentially usable by Belgian managers, e.g. using legally accepted rates for herbicides. Stem volume, height and density reduction was assessed after one or two years depending on the treatment. No tested method allowed a complete eradication of the clone. However, stem injection with glyphosate-based herbicide caused the highest damage. The year following injection, no sprouts were observed. Two following year, however, stunted shoots sprouted. Among mechanical control measures, repeated cuts combined with native trees cuttings plantations most appreciably reduced knotweed development. The most efficient methods we tested appear as tools for curbing knotweed invasion but are not likely to be used to eradicate the species. As such they should be included in a more integrated control strategy, together with prevention and public awareness campaigns. [less ▲]

Negative impacts of invasive plants on natural habitats have been widely demonstrated. Hence, the management of invasive plants, aiming at eradicating, or at least controlling their spread, is being more and more developed. For this purpose, we need to identify the most efficient management techniques which could lead to the restoration of invaded ecosystems. Up to now, management methods mentioned in literature were pragmatic tools and often lacked scientific assessment. For several years, we have tested similar mechanical and chemical management techniques in the field on highly invasive plant species, representative of different life forms and invaded habitats: herbaceous rhizomatous perennial Fallopia japonica, ligneous rhizomatous Spiraea spp., ligneous root suckering Acer rufinerve and ligneous stoloniferous Cotoneaster horizontalis. We investigated the efficiency, cost and feasibility of these techniques, and their effects on the restoration of invaded ecosystems. The best performing management technique was found to be highly species specific and was also influenced by the invaded habitat type. For these perennial species, long-term management must be considered, to reduce their competitive capacities with repeated mechanical or chemical techniques (cutting or pulling out several times a year, injection combined with mechanical methods, etc.). For species with sexual reproduction, like Acer rufinerve and Cotoneaster horizontalis, seed bank and seed dispersal must also be taken into account to avoid dissemination when managing. We can conclude invasion plant management is usually expensive and hard to implement but some results are encouraging and show the importance to carry on research on invasive plant management methods.
