Effect of grassland management on the occurrence of the poisonous species Senecio j acobaea

摘要：

Senecio j acobaea L.( tansy ragwort) is a poisonous weed in grasslands of various continents (e.g.United States, Great Britain, Central Europe, New Zealand).In Central Europe, the species seems to have increased its dispersion in the last years.The further spread of the species into farmland must be prevented because S.j acobaea contains pyrrolizidine‐alkaloids that are toxic for cattle and other livestock (Duby,1975).We thus conducted a survey in Switzerland to assess the influence of management practice and site conditions on the occurrence of this species.Our aim was to find a combination of conditions where the risk for the occurrence of S.j acobaea was either remarkably high or low.Such data will allow strategies to hinder the weeds dispersion.
