Inventaire et gestion des arbres d'alignement, des mails, des arbres isolés ou en groupe au sein du Parc naturel régional Oise-Pays de France

Abstract : Different management and promotion tools for the PNR Oise-Pays de France treed patrimony have been developed between 2009 and 2012. A typological inventory of tree lines, mails, tree clumps and lonely trees have been carried out. This tool revealed a treed patrimony characterized by poor mechanical and physiological conditions. Management suggestions have been made on three scales (Park scale, municipality scale, management unit scale) and are available online thank to the setting up of a WebGIS. Half of tree units inventoried in the Park should be replaced within 10 years. This will urge local powers on financing and planning such costly works on a longer term. In addition, an identification approach of potentially champion trees has been initiated. Today, 34 trees are able to get a label after the application of age-class adapted criteria. This label will be delivered to the manager after signing an agreement ensuring better arboricultural practices. A questionnaire has been designed in order to adapt the tools for the tree managers. Large differences between respondents have been shown in human and financial resources and in interest in the treed patrimony. Recommendations concerning people involvement process in planning projects are prescribed. As a conclusion, suggestions to follow a sustainable tree policy in the Park and inventory supplements are made.
