Das Absinken der Oberfläche im Treenetal während des Spätholozäns

The stated lowering of the surface in the valley of the Treene is substantial. According to the height
of the peat located on slopes, a decline of at least 150 cm is computed. A considerable part of the total
drop took place before the drainage operation carried out around the year 1924. It cannot be ruled out
that the damming-up of the Treene in the year 1570 played a major role in the lowering of the surface
(Borger 1998; cf. the contribution by G. J. Borger in this volume). However, even prior to this, drainage
of the bogs had on all accounts been undertaken by man to a limited extent.
