[email protected] Résumé. Une revue de la recherche au cours des quarante dernières années dans le domaine des barrières racinaires est présentée. La recher- che est la conséquence du besoin de minimiser les conflits entre l’expansion des racines des arbres et les infrastructures urbaines telles que rues, bordures de rues, trottoirs, fondations et conduits souterrains. L’histoire des barrières racinaires, des conventions de terminologie et des différentes classes sont décrites. Les résultats des expériences et des études sont examinés, les succèset échecs des différentes barrières sont notés et des orientations pour les futures recherches sont suggérées. Zusammenfassung. Hier wird ein Rückblick über die vergangenen 40 Jahre zum Stand der Forschung bzgl. Wurzelbarrieren vorgestellt. Die Forschung hat ergeben, dass ein Bedarf besteht in der Minimierung der Konflikte zwischen sich ausdehnenden Baumwurzeln und urbaner Infrastruktur, wie Straßen, Bordsteinen, Gehwegen, Fundamenten und Untergrund-Versorgungsleitungen. Die Geschichte von Wurzelsperren, unter näherer Bezeichnung der Konventionen und unterschiedlichen Klassen werden hier beschrieben. Die Ergebnisse der Experimente und Umfragen wurden untersucht, die Erfolge und Misserfolge der ver- schiedenen Wurzelsperren beschrieben und Richtungen fürkünftige Forschung festgelegt. Resumen. Se presenta una revisión de la investigación en barreras de raíces en los pasados cuarenta años. La investigación resulta de la necesidad de minimizar los conflictos entre la expansión de las raíces de los árboles y las infraestructuras urbanas tales como carreteras, guarni- ciones, basamentos y servicios subterráneos. Se describe la historia de las barreras de raíces, nombres convencionales y clases diferentes. Se examinan los resultados de los experimentos y encuestas, así como los éxitos y las fallas de diferentes barreras y se sugieren las direcciones para futuras investigaciones. ©2008 International Society of Arboriculture
