Since the beginning of agriculture weeds have been controlled for the sake of crop yield and quality. Due to a general intensification of agriculture (including weed control), the weed flora of arable land has changed and a decline by 30 to 50% in the number of weed species has been observed in the last 30 years. To save rare species, various programmes have been initiated to which agriculture has to contribute since these species depend on arable land. Since a close cooperation between agriculture and ecology is needed in this field, both have to define their aims carefully. There are now new concepts in weed control which tolerate weeds to a certain extent for economical and ecological reasons.
