Early-maturing G. N. Vysotsky plantations as an example of objective stand cultivation
Journal Title: Лісівництво і агролісомеліорація - Year 2012, Vol 121, Issue
Abstract
The paper presents the results of retrospective analysis of the taxation parameters of forest plantations with the main species of Siberian larch, European ash and silver birch for 85-year period of growth. Afforestation was created at the suggestion of the famous scientist George N. Vysotsky as “hasty cultures” and was originally planned as fast-growing. In 20 years, the growing stock of plantations was 160 m3/ha. As a result of untimely and non-purposeful cleanings, the growing stock increment has dropped and was 404 m3/ha at 67 years and 487 m3/ha at 85. Yield analysis of the sample trees confirms the exceptionally high growth rate of selected species and validity of the forest plantation composition. To achieve high levels of larch-ash-birch cultures productivity it is necessary in time, by age 40, to withdraw the birch from and to form two-layered stands. It is necessary to conduct intensive tending felling of ash in the I layer, with the main species larch and ash, and to assist in forming of canopy dominated by linden, in II layer. A multy-layered larch-ash planting formed will provide growing stock to 500 m3/ha by age 60 and 600–700 m3/ha by age 85.
