Reforestation process of fresh oak-pine forest in the State Enterprise «Kolkivske lisove hospodarstvo»

Abstract

The analysis of the peculiarities of natural forest regeneration of Scots pine in the conditions of fresh oak-pine forest of the State Enterprise «Kolkivske lisove hospodarstvo». The influence of grass cover closure, forest litter thickness and microrelief on the course of natural reforestation has been determined. Studies have shown that the largest amount of undergrowth of Scots pine and oak is present in areas with low and medium closure of grass cover. The optimal thickness of forest litter for the growth of Scots pine and oak in plantations of 68 years of age – 1-3 cm, in 65-year-olds – 3-6 cm, and on the log – up to 2 cm. In the low and flat areas of microrelief, the amount of undergrowth of pine and oak is the highest, and the lowest – on the micro-elevations, which indicates the formation in these conditions of the optimal environment for the emergence and preservation of its seedlings.
In closed pine-oak plantations with developed undergrowth and grass cover, 2-3 years before felling, it is advisable to cut down the undergrowth, which will promote natural regeneration (loosening of the soil) and thinning of the stand.
