Anthriscus sylvestris - biology control and peoples perception of cultural landscapes

摘要

In a four-year multidisciplinary study, we are combining studies of biology and different control measures of Anthriscus sylvestris with studies on people's perceptions of their cultural landscape, with special emphasis on A. sylvestris. We studied the effect of cutting the taproots at different lengths in three pot experiments (greenhouse, Ithaca, NY, USA and As, Norwa and outdoors, Tromso, Norway). Removal of the upper 4-5 cm of the root may be sufficient for controlling it. Demonstration trials innorthern Norway showed that application of herbicides (mecoprop-P, thifensulfuron-methyl) effectively controlled A. sylvestris, whereas 2 cuts in spring and summer or 1 cut late in summer did not reduce infestation. Through case studies in coastal communities in Vads0, Her0y and Sandstrand, northern Norway, we explored how changing cultural landscapes strongly influence people's perception of place. Anthriscus sylvestris seems to symbolize a degradation of the cultural landscape, representing a contrast to the living and well-managed landscape that people want to live in.
