1) The results of the pollen analysis indicate that the pollen deposited at the site comes from a rather open landscape. Most of the trees occur only sporadically or come from the local wetland vegetation (Salix, Alnus, Sambucus). Interesting are the finds of trees which could represent useful or cultivated plants like plum (Prunus-type) and hasel nut (Corylus). A definitely cultivated tree is the walnut (Juglans regia) found in samples from both 11th and 13th century. The herb vegetation, apart of grasses is strongly dominated by pollen of plants growing in disturbed habitats or occurring in the cultivated fields like weeds (Agrostemma githago, Centaurea cyanus, Polygonum convolvulus, Convolvulus sp., Papaver phoeas-type). Those results are also very promising for further integration and comparison with the macrobotanical data. 2) The wood and wood charcoal analyses have indicates that the charred wood was used most probably for fuel as opposed to that deposited in a subfossil state of preservation. The subfossil wood could originate from local vegetation or from activities related with foddering or the use of oak for specific purposes different than fuel. 3) The results of the analyses now are in their final stage and can now be further integrated with those from the macrobotanical and phytolith analyses in order to achieve a better understanding of the plant use at the site.
