Abstract This essay discusses different explanations and interpretations of what characterizes large areas containing clearance cairns (cairn fields). Results from the analyses show that there are different explanations about when and why cairn fields and clearance cairns occur. Explanations vary from introduction of the wooden ard in the early Bronze Age to the introduction of rational hay-making in the Roman Iron Age.  There is, anyway, relative agreement considering why and when cairn fields were abandoned. The reason suggested is an increasing pasturage with the consequence of reducing soil to poverty during the period of the Great Migration or in the Viking Age. The most likely cultivation system in cairn fields is a system consisting of both intensive and extensive characteristics. The latter coincides with the probable mobility of settlements. When it comes to cultivation a possible development is the use of hand-tools initially, followed by an increased use of wooden ards. Stones from clearance cairns have often been used when graves were built. Sometimes this is interpreted in ritualistic and symbolic terms, but a practical explanation seems most likely. Graves in areas of clearance cairns are usually located nearby the settlements. This is either indicating a more developed individualized ownership of land in the Iron Age or a stronger cult of ancestors in the period. When the element of ritual and symbolism in the agriculture practiced in areas of clearance cairns is discussed this is, almost without exception, a question for archaeologists, though many archaeologist, like culture geographers, emphasize practical explanations to different phenomena.   KEYWORDS: Areas of clearance cairns, clearance cairns, cultivation systems, settlements, ritual and symbolism.

<p>This paper aims to investigate the connection between clearance cairns and burial cairns. From this point of view I try to answer the questions why they are built in the same area and why these two different types of cairns are so similary constructed.

This paper aims to investigate the connection between clearance cairns and burial cairns.

During last decade there has been developed concept of so-called ecosystem services (e.g. Millennium Ecosystem Assessment, 2005) in matured countries. This concept focus especially on identification of benefits resulting from intact ecosystem and also on various ways of taking all those benefits into account when dealing with decision-making process of market economy. Goal of this concept (among other things) is to keep currently freely available ecosystem services in nature as they are and also to ensure natural conditions for life won't be becoming worse. Landscape of eastern Ore Mountain has its specific character especially because of few unique ecosystems which don't occur in other locations at all; or they are presented there but not in such high volume. We can consider mountain meadows, natural streams and clearance cairns at the most important local unique ecosystems. Main goal of diploma thesis is to analyze recreational and mainly aesthetic values of clearance cairns. Even though clearance cairns are important biotopes there was quite small attention dedicated to them in existing analyses made in Czech Republic. That is in heavy contrast to attention dedicated to those biotopes in other areas, e.g. in eastern part of Ore Mountain belonging to Saxony where local inhabitants appreciate clearance cairns so much that every single section of them is completely documented (resulting into 1.000 kilometers of documented clearance cairns). Diploma thesis is based on methodology using analysis of primary data obtained from empirical research. Research was realized in eastern Ore Mountain during summer 2013 and author of this thesis was actively participated both in preparation phase and also in realization phase. Thesis also uses random utility theory, discrete choice models and also stated preferences methods (e.g. Bateman et al., 2002). Multinominal logit model and random parameter logic model are used for values estimation. Based on performed analysis thesis verifies or disproves hypothesis saying that willingness to pay for clearance cairns is statistically insignificant (i.e. people don't consider this landscape element as having significant value). Diploma thesis results will be used as a suggestion for obtaining clearance cairns management.

<p>From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systems</p><p>The shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil. In sandy soils, and other fine soils, the ard will at each turn deposit small amounts of roots, soil and debris at the edge of the field, which over the years will build up the walls of the celtic fields. But in boulder-rich soil the ard will constantly have to be lifted and tilted, which means that the material will be released before the ard reaches the edge of the field. Since crops, vegetation, houses, field system areas, etc. are identical or at least similar in both landscape types, they most likely represent the same farming system with hay-meadow – stabling – manure – intensely cultivated fields</p><p>In most provinces in southern Sweden, the pre-roman celtic fields and clearance cairn areas were replaced by geometrically laid-out strip fields or different kinds of stone-wall complexes enclosing the fields and farms, around AD 200, but not in Småland. There, the clearance cairn areas were used and extended throughout the Iron Age. How can this regional variation be explained? A comparison between the different landscape types reveals no significant differences in tools, crops, houses, etc. that would support that the difference is explained by a shift in farming systems. A more likely hypothesis is that the difference is due to regional pre-state or early-state political structures with an ambition to control land-use. This is based on the observations that 1) within each region the physical appearance of the fossil landscape is very coherent; 2) between the different regions there are significant differences, and; 3) the different systems were introduced approximately simultaneously in the regions Gotland, Öland, Östergötland, Uppland and Västergötland. This hypothesis implies that Småland either had a separate political structure which chose to keep the old clearance cairn land-use system, or lacked a corresponding regional structure.</p>
