The article summarizes the observations about forest types from different parts of Estonia. The chosen examples represent the normal forest where age class division is natural and the species composition has not been altered through felling or grazing. These are mainly found in the areas of earlier manors of the nobility. The samples are only from mineral soils. Vegetation analysis and middle-European height-over-age-survey were made.
Because of the great share of herb-rich-forest the forest type classification for Estonia is complex. There are many types that have not been described earlier.
The study describes the characteristics and the vegetation types of the heath forests, fresh forests, half-herb-rich-forests and herb-rich-forests.
