Large-scale in recent years withering basis of the forest fund of the Polissia region – pine forests confirmed that the dominant single-storied even-aged monocultures are not able to withstand the modern challenges caused by global climate changes. Therefore, there is a need to transform pure pine forests into mixed ones, which have higher biological stability. The article evaluates the prospects of using one of the original subsidiary species of pine - common oak. The study of the state of natural renewal of oak in young pine forests was carried out on the basis of five forestry state enterprises: «Volodymyr-Volynske forestry», «Kovelske forestry», «Kolkivske forestry», «Ratnivske forestry», «Starovyzhivske forestry». Information is given on the number of natural regeneration of oak in young pine trees. It was established that mixed oak-pine formations of the curtain-mosaic type can spontaneously form in those areas where the pine initially had a significantly thinned density. Significantly better growth and development of oak biogroups of natural origin is observed in such young trees. A conclusion is made about the expediency and perspective of purposeful inclusion of oak of natural origin in the practice of the process of reproduction of new forests, which corresponds to the principles of ecologically oriented forestry.
