« Messicoles » : conservation des plantes messicoles dans les parcelles cultivées : caractérisation des systèmes de cultures favorables, rôles fonctionnels, perception par la profession

Abstract : Segetal plants, or “messicoles” as they are known in French, are weedy inhabitants of wheat crops (mainly winter cereals). The national list of segetal species includes 102 taxa; of which 7 are extinct, 52 threatened, 30 to be kept under close observation and 12 abundant. Data on their distribution indicates that they are mostly in decline. As their survival is intrinsically linked to farming systems, we need to improve knowledge on their relationships with land management in order to establish a sound scientific basis for protection tools, to support and guide farmer conservation measures and to disseminate concerns for segetal biodiversity to agro-environmental policymakers. We propose to examine: 1) the relationships between the abundance and/or the segetal richness and farmer practices in several farms in different regions; 2) the potential ecosystem service provision as resources for foraging insects through identification of the pollen of segetal plants and their abundance in pollen traps fixed on bee hives; and, 3) the perception of segetals by professional actors to identify ways of thinking that underlay the diversity of discourses and present practices about them. Joining national efforts for similar goal and participatory approach could help European Community to adopt agro-environmental measures towards biodiversity conservation.
