Abstract
The Department of Geology at the university and the Swedish National Heritage Board have initiated a collaboration on palaeclimate reconstruction. The main source of information is a sediment sequence from the dead-ice lake of Lyngsjön, just north of Everöd on the Kristianstad plain. The core contains information from far back in Holocene but the analysis and interpretation can be facilitated if solid information regarding the more recent environmental changes exists. Since the natural vegetation has in large been replaced by agriculture during
historical times, the top sand and silt layers have begun to move through sand drift. This has very likely affected the sediment sequence. The purpose of this work is therefore to map the landscape... (More)
The Department of Geology at the university and the Swedish National Heritage Board have initiated a collaboration on palaeclimate reconstruction. The main source of information is a sediment sequence from the dead-ice lake of Lyngsjön, just north of Everöd on the Kristianstad plain. The core contains information from far back in Holocene but the analysis and interpretation can be facilitated if solid information regarding the more recent environmental changes exists. Since the natural vegetation has in large been replaced by agriculture during
historical times, the top sand and silt layers have begun to move through sand drift. This has very likely affected the sediment sequence. The purpose of this work is therefore to map the landscape development during recent centuries on the Kristianstad plain by analysing historical documents such as old maps, literature etc. Sand dunes and pine
plantations are two useful climate indicators since they signify sand drift and are hence used as the most important source of information. The main emphasis has been placed on dating a number of dunes already identified from earlier research and the results show that in most cases they formed in the late 17th century to the early 19th century. This correlates with three phenomenon that are pointed out as causes for the sand drift:
1. A population increase that intensified the agriculture and decreased the top vegetation.
2. Merging of smallscale agriculture into large ones which decreased wind protection from pine plantations.
3. An increase in dryer easterly winds (Less)
