 I will show you briefly my new studies. It's a part of my PhD thesis and it contains whole Bielska Plain. Last year during EAA I said a few words about the Bielzka Forest, which is a huge part of Bielzka Plain, but now I'm after teledetection through whole Bielzka Plain so that I would like to show you. And the Bielzka Plain is located in northern eastern part of Poland. It's total area of 2,800 square kilometers and about 35% of this area is covered by woodlands. And as I said it consists one of the biggest and best preserved woodlands in Europe, the famous Bielzka Forest UNESCO monument with area of 811 square kilometers. And if you will look at this teledetection, that obviously we find out that in this Bielowieża Forest which is outline with blue color, we've got a huge concentration of barrels with triangles. I pictured barrels slash mounds because without excavation we actually don't know if it's a barrel as a sepular place. With the circles it's charcoal kilns and with green points we've got tar kilns. I will show you afterwards. And if we look at the whole monument or archaeological sites with anthropogenic relief, we can find out that all these three groups, so charcoal kilns, mounds and tar kilns are almost 90% of all of detected by us sites. And with this huge amount of features like this I tried to make some basic typology for them and I found that we've got like five types of barrels. We've got type one, it's a single mound and I calculated it by buffer that with 150 meters of buffer dimension, we've got no other features like this. We've got type two, it's a pair of mounds that occur one next to other. We've got type three, it's linear semi-line cluster, it's a cluster of barrels that indicates some kind of line. And we've got two kinds of clustered one I called tightnit, it's a buffer less than 50 meters between one to another feature and type five free-floating cluster, it's more than 50 meters between mounds and as this mound slash barrel I called only features that got preserved whole of the embankment because we've got also a modern mounds. Nowadays we know that they occur a little bit different because the embankment is always destroyed so we've got three different types of charcoal kilns with ditch around, with holes around and without this ditch visible nowadays. We've got huge charcoal piles, new rivers, always new rivers. It's a huge embankment destroyed in the middle because probably the wood, the charcoal was taken away. We've got tar kilns, it's a very interesting and very similar feature, it's always in the same type and we excavated one in this year, it's dated for 18th century and we've got some mounds that it's probably for sure modern, it's built from charcoal and soil but we don't know which kind of activity it was used for and I catalog it in GIS of course but also on sheets with whole information. It's also a part of the project that I'm involved in about Białobieża so we've got coordinates, place it in on a map and some DPM with cross section of every each monument and going back for a second to Białobieża forest I call it moundscape because as you can see on the whole of this area we've got 1724 mounds and as you can see we've got different kinds of them, we've got huge charcoal kilns in the south part near the Hainówka here is the biggest city in the neighborhood of this forest so it's probably connected with that and still when I'm talking about huge cluster of kilns I mean it's like 50 maximum of them so in the other parts of Poland or in Germany we've got thousands of kilns yes so it's still very small amount of them and as I said numerous mounds here are very good preserved not because of extensive settlement it's the northern part of our country and it's a periphery of settlement in actually till the late middle ages so the preservation is much more important than the extensive settlement and what we found in Białobieża are the very interesting features that we think are the remnants of ancient fields my colleague worker on this subject for his PhD is probably mostly from middle ages because it's a little bit different than the Celtic fields that we know from western Poland but still we've got even cases when the mounds are located on the this embankment it's almost invisible in the field so all we can do is is detect them with Lajdar and we thought that it's only occurred in the Białowieża and now I will show you the rest of this this Bielska plain here we've got a cluster of mounds probably in this type 3 linear linear settle but we've got also the charcoal kilns in the same woodland and you can observe that actually all of the preserved mounds occur only in woodlands but we've got also this kind of feature as this filled remnants very close to the burrows and last year I present our work around the this line clusters it's dated always to early medieval period to eighth ninth century after Christ and on the Bielska plain we've got a similar cemetery in line but in the neighborhood of a hillfort in Zbucz and also I found out that we've got all types of these clusters of burrows in the rest of the Bielska plain so we've got these type need clusters single burrows and floating clusters and this year during the Białowieża project we chosen to excavate one of these singular burrows because through the three years of our project I decided to dug only mounds that are burrows that I have questions for and the main question was to understand the pattern for this typology and this singular burrow was the first one the Białowieża that we dug and it we found only a few shards of early Bronze Age pottery in a pit in the close neighborhood of the embankment and everything inside was empty of the embankment and it's probably a very early Bronze Age burrow but we've got some we were waiting for dates but if it's true it's the oldest the oldest burrow in in this region in the Bielska plain and some statistic that the Białowieża forest is only 30 percent of the whole Bielska plain but there we detect 1,724 mounds which is 86 percent of whole detected burrows in this region and as you can see on the rest of the Bielska plain I found only 284 mounds which is 14 percent but only 35 percent of the Bielska plain is covered with woodland so only 6 percent of the whole Bielska plain beside this Białowieża forest is woodland the rest 75 percent was destroyed by modern ploughing and here you can see also this burrow landscape of Szczekotowo reserve in the middle of the Białowieża where sometimes these clusters of burrow the cemeteries occur in one place so this is very very simplified idea and I will never publish it it's just for presentation of which burrows were excavated and it seems that in early Bronze Age we've got single burrows in early Iron Age and in the Roman period we've got these free floating burrow clusters in early medieval period we've got line burrow clusters and in 9 to 12th century after Christ we've got tight-knit burrow clusters very very similar to that Anna showed us today so I hope it might be an analogy because it's the border of that in that time and we've got 70th to 9th century after Christ in all these modern mounds so charcoal and tar kilns should be from that time and unfortunately we still don't don't know anything about pair of mounds we excavated one in last year and found nothing okay but this is difficult how to try to understand and to date such big amount of of burrows when we've got excavated like two percent of them or less and still the the Aldeja forest is preserved with different kinds of environmental problems so we usually dig only one quarter of of a single burrow so that's the problem of excavating and understanding this burrow landscape without digging actually and to conclude in the Bielska plain we have opportunity to investigate burrow landscape in the Biały Wierze and compare how it was destroyed by modern ploughing in the rest of the Bielska plain because I assume that we should have much more burrows or mounds with these modern mounds in the rest of the this this region but it was destroyed by urbanization or modern ploughing which is deadly for this prehistoric landscape thank you
