Abstract
The article presents the index of changes of forest site type, composition of species (species diversity, composition agreement), vertical and age structure, crown density and stand volume since 1969 to 1988. The index has been tested in the Jasień Forest (experimental forest of Warsaw Agricultural University in Rogów) covering 840,05 ha. Changes of site structure in 1989 influenced the result of the test of the stand composition and stand diversity. Share of pine stand reduced for the better of leaved stand, mainly with oak. Change growth of vertical structure, mean crown density of stand in the I-III age class and stand survival were found.
