Journal Title: Лісівництво і агролісомеліорація - Year 2012, Vol 121, Issue
Abstract
In the stands of forest enterprises of Sumy Regional Administration of Forest and Hunting Management the part of area of pine stands from area of forest covered lands has a tendency to decrease from North to South, and the part of oak stands increases from North to South. In the stands of Sumy region 39 forest types are described, and pine forests are represented by 25 forest types. Total number of forest types decreases from South to North, that is from forest to forest-steppe part of region, and number of forest types with pine stands increases from South to North. Among pine stands of Sumy region subors (average 52.5 %) and sugruds (39.5 %) dominate by trophotop, fresh types (average 92.8 %) by hygrotop. Part of sugruds, wet and humid types increases from South to North, part of dry types decreases from South to North. By forest site conditions of both all stands and pine stands В2 dominates in SE “Shostka Forest Enterprise” (forest zone), in SE “Okhtyrka Forest Enterprise” (forest-steppe zone) D2 dominates for all stands and В2 dominates for pine stands. Increase of productivity of pine stands is possible at the expense of increase their area in optimal forest site conditions. It will give the possibility to increase the timber stock per hectare per 75 % (56.6 – 84.4 % in different enterprises), and such reserves are greater in the northern part of the region.
