The  study describes the natural regeneration state of a forest on coarse sandy  soils. The natural regeneration was studied in three different ecological  conditions: in 30 to 60 year old Scots pine stands, in a 62 year old mixed  stand of pedunculate oak and red oak, and on the free field.     The analysis of the regeneration groups revealed that the first settler  maintained a dominant social position during the following years after the  settlement. The structural basis is consequently laid out early. This means  that the forest practice has to consider the very first phase of the  regeneration as determining for the following evolution of the regeneration  groups.

In 70  years old homogeneous Scots pine stands, bordered by a hardwood belt, an  analysis was made about the spontaneous ingrowth of natural seedlings. The  analysis involved especially the following points: species and stem number,  influence of the hardwood belts, diameter and height distribution, age,  growth and structure. From the age of 30 years, a spontaneous regeneration of  hardwoods established in Scots pine stands. There are on average 7,000 plants  per ha, 80 % of which are black cherry and another fair number are red oak  and pedunculate oak. The regeneration has an average age of 25 to 30 years,  it is uneven aged, contains several diameter and height classes and has  already partially penetrated the upper stratum.     The spontaneous ingrowth allows to convert in a simple way the homogeneous  coniferous stands into mixed hardwood stands.
