Journal Title: Лісівництво і агролісомеліорація - Year 2015, Vol 127, Issue
Abstract
Collection and compilation of data on Ukrainian forests, in which there were marked pathological processes as of 1994, 1997, 2000, 2003, 2006 and 2009 years, showed that for the period of observations the area of such forests increased by 1.8 times. In 1997, the proportion of such plants was 2.4 % of forested area, and it was 5.6 % as of 2009. As of 2009, the most widespread were the pathological processes in spruce stands (19.6 % of spruce forested area), slightly less they were in oak (6.1 % of oak covered area) and pine (4.9 % of pine covered area) stands. For the observation period, the oak plantations, in which pathological processes were observed, grew unevenly by 12.5 thousand hectares, the pine ones - 8.5 thousand hectares, spruce - after 2000 - 24 thousand hectares every three years. As of 2020, in the case of the modern trends will continue, the area of pine stands undergoing the pathological processes in Ukraine will be about 140 thousand hectares , oak - 230 thousand hectares, spruce - about 500 thousand hectares, birch - 12 thousand hectares and alder - about 10 thousand hectares.
