Résumé : Since 2015, the Regional Natural Reserve of Val Suzon (Côte-d’Or) has been the subject of archaeological researches based particularly on the analysis of LiDAR datas acquired in 2013. Thanks to these datas, many traces of activities preserved under the forest can be identified and studied. These archaeological structures, characterized by a great diversity of ages, origins and natures, make it possible to apprehend the evolution of this territory over the long term. In addition to LiDAR, various sources are also exploited, such as textual archives and old plans. These documents provide additional information to those from LiDAR and also provide information, for example, about the exploitation of Val Suzon’s natural resources or the transformation of the landscape over time. This diachronic and multi-source approach is illustrated presently through the study of some structures identified on the plateau of Messigny. From the Bronze Age tumulus to the trenches of the war of 1870, this area of approximately 200 hectares presents a wide range of archaeological structures testifying to the composite history of this territory which is occupied nowadays by a forest. In addition, the geomorphological conditions of this area have allowed the preservation of exceptional traces left by the repeated passage of animals. It appears however that these traces, like other micro-reliefs, are only visible in the areas where the forest has been maintained for several centuries, despite the episodes of deforestation that occurred in Messigny. Finally, the research carried out on the Val Suzon addresses issues specific to forest archaeology as well as forest history and historical ecology, in particular by focusing on the question of the impact and legacies of past dynamics on the current environment.
