A population dynamic approach to the control of Anthriscus sylvestris (L.) Hoffm.
Abstract
The life cycle of A. sylvestris (which dominates disturbed grasslands on road verges and river dikes) was analysed to examine possible causes of its dominance and to seek a feasible control strategy. Clonal propagation was found to be more important for population growth than sexual reproduction. The balance between the two could be influenced by different management regimes because mowing at the onset of flowering suppressed clonal propagation. The usual management regime for road verges and river dikes in the Netherlands of mowing in late June stimulated vegetative spread and enhanced the problems caused by dominance of this species.
