 I'm going to talk about the forest of Bercé. It's important because forests are not well represented in archaeological studies in France. Those are put disciplinary and inventive methods, not focused on the results, but mostly on the compatibility and this type of research in forest environments. To begin, the forest of Bercé is located in the department of Sartre in France, precisely about 40 kilometers south from Le Mans. Bercé is a state-owned forest with an area approximately of 5,480,000. Shared among 11 tons. The current vegetation is essentially made of what beach forest. It is mixed with unscented forests that stand on modern reforestation. Part of those are comprised of resinous wood which are aged from mid-18th century. This forest is established on a very fertile land. The first evidence of archaeological sites were reported back from the mid-19th century by Yves Boucher, a forest agent working in the forest. Several studies were focused on this forest over the past few years. They were done by different researchers with various problematics. They focused their studies on high-run metallurgy. Metallurgy is my rocks. The control of medieval forest and closer on generally all incense settlement in this area. The studies of the Bercé forest based on traditional method mostly like the study of uncensored and field-working, but also new technology. For example, LiDAR, Polovir Elemental Surveys, on archaeometry. The study was not carried out by a research group, but by independent researchers. Today, I present the synthesis of this book. The LiDAR has revealed several hundred archaeological sites. It also permits to observe many geomorphological sites, a few hundred on closer, several hundred shaft mines on the left. Eight hundred shaft mines. Parcelat. I don't use the good word Parcelat, administrative fragmentation, probably used in archaeological... Sorry. Also, many cluts of inspecified sites. The four-way parts where there are the few restantric olical sites are located at the north and southwest of the massive. There are modern resinous ruffles and resinous roads are few adapted to a laser beam of LiDAR. If this method gives the opportunity to observe a lot of sites and allows to establish some kind of modality of occupation, it does not allow to establish chronology. To obtain chronological information, we need it to feed-working server. The forest, even if they can blow up every kind of archaeological remains, are able to protect archaeological sites and many of them are in elevation. For example, we have been able to observe some uncluttered military training camps in the right. It's a military training camp to the end of the 19th... 19th century. And left. We have tough mines. And we observe accumulation of slag sites. I don't know the word in English for that. The feed-working allowed to highlight the existence of a hundred-of-faculate-racket site adapted from photo history to the present day. It's not easy to give a precise chronology of these remains, because of the absence of excavation. Few artifacts were discovered in feed-working but often of any stratigraphy. Furthermore, we know that charcoal clamps, structure of charcoal preparation, were still in function until the 20th century and probably before to feed blueberries. When I've informed any charcoal clamps carrying samples, allowing for carbon or protein analysis. I'm sorry. For now, only two charcoal has been dated to the antiquity. There are a lot of fundraiser. Red on top of... ...and truss of Parcelar. Yellow. And I want our extraction and reduction of unsumed rod... ...orange. Probably material. Some of them can be related to forest use and other probably more ansumes. For the recent occupation, we can use a writing source. But for older ones, artifact and carbon-14s won't permit to date anything because by the evidence there is nothing to date. Only two charcoal discovered in this forest. We need to experiment, practice and improve other methods to suggest chronology hypothesis. At least we have an evident technical excavation to observe chronography and sedimentology. All of them are more negative. We suppose a relative chronology for many enclosures according to topography and shapes. The most of them seems to modern or medieval. The administrative fragmentation are set in chronology to remain the 10th final by historiography. For the iron etiology, there are few datations by carbon-14s and ceramics on medieval sources. We have many hypothesis, but it's a black site based on the typology of Salak. There are several types of them. Glacier, compact, et cetera. And the recensory in this area of research proves that some tips may be associated with historical periods. Probably iron ore is exploited during the Roman antiquity on central Middle Ages. The slag were analyzed by the fluorescence mix. We observe a chemical evolution of the rediction process. We also calculated the surface and volume of slag sites. We observe that most of the sites are small in volume except one. Thanks to the complementary geometry and multidisciplinary of this unit, it's possible to obtain some current information concerning the evolution of the expedition process of this porous massif. The rich shash The rich shash of these different sites aim to establish a chronology of occupation and to find if some site could be contemporary. Working together. Presently, we have a few datations. The study of the unsentment allergy introduced the polematics of technological evolution over the time and of produced quantities. The study made of Bercet constituted a fast way to understand the archaeological remain and allow us to see Bercet with a fresh eyes. Today, a new non-invasive visibility approach to allow us to create new methodology well adapted for modern forest management on archaeological site preservation.
