Abstract
Yield table of beech by the Forest Research Institute’s long duration research network was publicised in 1968, and later in 1983. Since then, a great amount of data was accumulated from the University of Sopron – Forest Research Institute’s (UOS-FRI) long duration forest yield and silvicultural research network by continuous recordings. From that database new yield functions and yield tables were made in favour of more accurate estimation of beech yield. 1542 digitalised records from 337 parcels were processed, from those great differences were noticed compared to the previous tables. Besides making the traditional yield table, the methods of calculations were given in detail, from which a forest stand’s individual growth trends can be calculated. The tables were made for 100% beech mixture ratio, closure and density.
