| Résumé : | Asulam and glyphosate are frequently used in France to control Bracken (Pteridium aquilinum). We attempt to understand, with this type of experiment, how herbicide and environment modify plant community and to determine which of the two treatments is more favorable to floristic diversity. The environmental factor having the greatest influence on floristic diversity before treatment is the depth of organic horizon. Treatments have no effect (P=0,7) on species richness but glyphosate treatment induces uniformity of the different species cover and is favorable to species diversity quantified one year after treatment with Shannon and Simpson index. |
