Динаміка продуктивності насаджень поліського природного заповідника
Abstract
Abstract. The important role of forests in stabilizing natural environmental
conditions has been noted. The dynamics of the main mensurational indices of
forest stands of Polissya Natural Reserve during 18-year period (1998-2016) is
analyzed. It is noted that the main role in formation of forest cover of Polissya
NR is played by pine (85.8%), birch (13.3%) and alder (0.9%) stands. Oak
plantations make up a minor part (0.03%) in forest fund of the nature reserve.
When analyzing distribution of tree species within their groups it was found that
share of pine in coniferous management section is 100% and it does not change
over 18 years. Oak forms an insignificant part in growing stock of Polissya
Natural Reserve and is the only representative in the group of hardwood
broadleaves. The dominant place in the group of softwood broadleaves is overmature forest stands. There is a small proportion of young and immature
stands. Moreover, the proportion of young stands over the 18-year period has
decreased three times. The average growing stock is gradually increasing,
which indicates that forests at the enterprise are being managed rationally,
which makes it possible to increase organic mass and thus increase ecological
sustainability of forests and ensure their main function – natural environment
regulator. Site index classes for all groups of species have practically remained
unchanged during the research period and are currently equal to II.7 for conifers, III.0 for hardwood broadleaves and II.5 for softwood broadleaves. It has been found that forest stands of Polissya Nature Reserve are average in terms of their productivity, but there are noticeable positive tendencies in dynamics of their mensurational indices, which helps stabilizing ecological situation.
Keywords: Polissya Nature Reserve, forests, productivity, mensurational
indices, dynamics.
