Analysis of changes in the sanitary state of plant formations of large-leaved linden (Tilia Platyphyllos) in the Yanaul forestry of the republic of Bashkortostan for 2019
This article presents the results of a study of forest territories of the Yanaul forestry of the Republic of Bashkortostan for 2019. Of particular interest is the study of large-leaved Linden formations in the North of the Republic, since the forested lands of this region have long had the status of operational territories-they were subject to development and all types of use. Over the decades, the ongoing development activities on the forests much damage has been caused to the formation of large leaved lime. Until the 1980s, all types of lime cutting were banned here due to the fact that it is a honey crop. But after the removal of this ban in the Yanaul forestry, plantations were subjected to continuous and selective logging for the purpose of harvesting wood. After 35 years of continuous exploitation of Linden forests in the North of the Republic, they led to a sharp decrease in the natural renewal of the studied woody plant species, led to a large number of mechanical damage to the stand and diseases. At the moment, these activities have been discontinued due to the closure of the leading timber processing plant, which was engaged in harvesting and deep processing of wood, in particular Linden. Therefore, studies of annual changes in sanitary and phytosanitary conditions, as well as analysis of the dynamics of natural renewal of forest-forming species are necessary, which determines the relevance of this work. Continuous deforestation and lack of high-quality reforestation measures in the valuable Linden forest have led to severe disruption of the natural ecosystem. As a result of the violation of its integrity, pests entered the Linden tree formation, as well as other existing plantings, and a large number of diseases of woody plants appeared, which a few years ago almost completely destroyed such a unique forest ecosystem. At the time of the study, the aim of the work was to study the phytosanitary condition of wood plants in the Yanaul forest district after the termination of operational activities. The tasks included the proposal of measures for the restoration of valuable forest areas, in particular the large-leaved Linden formation.
