One of the most important factors for the sustainability and stability of forests is the presence of natural regeneration in them. In oak forests, the lack of natural seed regeneration of the native species is one of the main reasons for the catastrophic reduction in the area of such forests. Therefore, it is very relevant and timely to study the processes of natural oak regeneration in various forest growing conditions and the influence of various environmental factors on them. The study of the natural seed renewal of oak in stands of different forest types, density and compositions in the Ulyanovsk region was conducted for the first time. The purpose of this work is to study the natural seed renewal of pedunculate oak in the forest stands of the Ulyanovsk region in different types of forest, with different density and proportion of oak participation in the composition of the stand. The article presents the results of studying the natural seed renewal of the pedunculate oak in the oak forests of the Ulyanovsk region, depending on some inventory factors.
