"ABSTRACT
During the last decades the agricultural weed vegetation of Europe experienced massive quantitative declines, as well as declines in species diversity and phytosociological diversity. This study focuses on the fields within the conservation zone Lange Lacke (110 ha.), part of the National Park Neusiedler See  Seewinkel. These fields are enclosed in extensively grazed pasturelands and have been extensively farmed since 1995 with summer crops, winter crops and alfalfa. The main reason for the man-agement of the National Park fields is for the provision of grain food supplies to the wild goose populations to, as far as possible, reduce the agricultural damage they cause to the surrounding intensive farmland. The fields were conventionally managed for 16 years before their integration into the National Park. Since that time, they have not been treated with pesticides, were hardly fertilised and have been partially kept open to light by the regular grazing of geese. At this point the question arises whether beneficial weed communities, which are valuable from a nature conservation per-spective, could be established on those fields.
The agricultural weed vegetation of all 25 grain fields of the National Park, including 14 plots of winter crop, were documented by means of 60 vegetation surveys. Addi-tionally a further 14 field plots of winter crops from the surrounding conventional agricultural land were documented in 37 vegetation surveys. Both winter crop field blocks were compared using statistical significance tests. The vegetation surveys were conducted on the edge, as well as in the centre of the respective plots. Thereby the possible existence of a vegetative ecological edge effect could also be statistically reviewed. All vegetation surveys were analysed according to the phytosociological system and were, as far as possible, assigned correspondingly. The agricultural weed vegetation of the National Park fields was analysed in detail from a nature conserva-tion perspective and was evaluated in contrast to the "usual" weed vegetation of the surrounding area. A management action plan was developed for the National Park fields based on the analysis of nature conservation and the literature, with main objective of supporting species-rich segetal weed communities appropriate to the habitat..."
