Abstract
Semi-natural elements at the edge between the agricultural field and any other, field margins constitute real reservoirs of biodiversity. Influenced by dedicated management choices (i.e. mowing, grazing, chemical weeding), by the use and management choices of adjacent fields (i.e. cropping successions and operations, grassland management), and by the surrounding landscape, field margins are at the heart of current issues aiming at (re)conciling agriculture and biodiversity, at various spatial scales. By diagnosing the agroecological state of field margins, the biodiversity indicator Ecobordure introduces users to agroecological issues and leads them to question their management choices and the consequences of these choices in terms of ecological functionality. This article presents the Ecobordure indicator and the associated learning and diagnostic process. First, it details the principles and implementation of the Ecobordure diagnosis, about the agroecological state of field margins at different scales, from the plot to the farm and to the local territory. Then, it reviews the co-design process and the development of the tool in partnership. Lastly, it outlines the challenges of deploying a nationwide network built around Ecobordure to contribute to initiatives to support the agroecological transition.
