Managing field margins for the conservation of the arable flora / Philip Wilson (1994) 

Public Citation est un extrait de Field margins : integrating agriculture and conservation / Nigel Boatman (1994) Titre : Managing field margins for the conservation of the arable flora Type de document : Extrait d'ouvrage Auteurs : Philip Wilson (1958-) Editeur : Farnham : British Crop Protection Council Année de publication : 1994 Importance : p. 253-258 Langues : Anglais (eng) Résumé : The margins of arable fields are of great value for the conservation of endangered plants. Changes in farming practices during recent years have resulted in the severe decline of many species including some which were once very common, and some have even become extinct. There is therefore an urgent need for guidelines for the conservation management of these species and their communities. "The Wildflower Project" carried out between 1987 and 1990 showed that herbicide and nitrogen use were very important factors that could be easily manipulated within modern farming practice. The second phase of this project is designed to test these factors in practice and to provide some indication of the costs of management for the conservation of endangered arable plants.

The ecology and conservation of rare arable weed species and communities / Philip Wilson (1990) 

Public Citation Titre : The ecology and conservation of rare arable weed species and communities Type de document : Électronique Auteurs : Philip Wilson (1958-) ; Nigel Boatman, Directeur de thèse ; Peter John Edwards (1948-), Directeur de thèse Editeur : University of Southampton Année de publication : 1990 Importance : 385 p. Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Messicole Résumé : Since 1940, considerable changes have occurred in both arable farming practices and arable weed floras in Britain. The aim of this project was to investigate the ecology of a range of annual weed species in relation to farming practices, in order to suggest some reasons for the decline in frequency of some species, and to propose some methods by which populations may be conserved. A survey of the sites at which eight uncommon species are still found, demonstrated the strong association of the weed communities and the presence of individual species, with the cropping history and soil characteristics of fields. Climatic factors and the long-term histories of sites were also found to be important. Another survey demonstrated the tendency for the seed-banks of most weed species to be greatest at the extreme edge of fields. Four herbicides were tested against ten weed species, and the effects of levels of nitrogen application on 18 weed species were investigated. It is believed that herbicide use and the high levels of nitrogen applied to modern crop varieties have favoured their growth at the expense of weeds. The type of crop sown and the date of sowing also had a great influence on the development of the weed flora. Some species rely on a post-harvest stubble in order to set seed. Changes in arable weed communities and the status of rare species is thought to be a result of changes in the farming practices described above in addition to others not investigated. Management guidelines based on the experimental investigations are proposed. Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=149187 Wilson, Philip (1958-) , 1990.
