Scientists: Autumn will take the strongest cycle of mass drying

Senior researcher of the Polissya branch of the Ukrainian Scientific Research Institute of Forestry and Agroforest Reclamation. M. G. Vysotsky, candidate of agricultural Sciences Vasyl Wart and researcher Olena Wart told about the real situation with mass symmetry in pine plantations.

According to them, the process of mass death of pine forests in Ukraine due to the action of coronary and trachemoid complexes is rapidly evolving. Only in the forests of the State forestry cells of the coronoid and related diseases are already covered 200 thous. Hectares of pine forests, and existing pathological drop is estimated in the volume of 12 mln cu. Metres.

According to the latest monitoring researches, the current cycle of active growth of pests populations is formed, as a result of which in autumn (September-October) will be the strongest in the year of mass fade cycle. The increase in the acreage of the dead Sosniany can reach 50% to their volumes at the middle of the year. The situation is compounded and sharpened – on the whole Polissya area, except for the tip of the crown, the outbreak of mass reproduction of six-toothed cow is already diagnosed. As a result, the term of the burning of pine is inevitably accelerated and the transformation of liquid wood into wood.

Since 60% of the population of the coronoid is concentrated in the stevedoring and comprestious and Overstable Sosnyachah, provided that the operational measures to reduce the number of pests (which are reduced by imperfect normative base) settlement for 5-7 Years, these tree-states will be exterminated. In addition, it is especially necessary to emphasize that the third cells of mass drying of pine trees are in the forests of the Natural Reserve Fund, and their reserve value and ecological resource potential will continue to lose rapidly.

Thus, the mass drying of pine in Ukraine has already reached the level of ecological catastrophe, which is constantly being formed by bodies of state power and society.

Progressive dying of pine trees stipulates the urgent necessity of carrying out considerably increased volumes of normative and maintenance measures on localization and elimination of pests and diseases centers, and also results in compulsory their continuous Implementation.

Operative sanitary chopping is the basis of the established world and National forest protection practice, they perform the general function of minimization of consequences of Vsyhan by preventing huge losses from loss of quality and the cost of wood of pathological drop, Plantations become safe for the population, in a short time, the restoration of forests, etc.

At the same time, as European experience shows, sanitary chopping in case of timely use, taking into account the biology of pests, effectively reduces the number of scabies, prevent outbreaks of their mass reproduction and intense proliferation into all new Parts of Sosniany. In this case, exceptionally important is given (in particular, in Poland, Germany and a number of other countries) nedopuŝennû formation and destruction of the first (spring) generation of the top loaf, which prevents further formation of the following significant generations The pest and subsequent development of mass Vsyhan.

Scientists note that, for example, in Slovakia, where sanitary-and-health measures are minimized or not applied, at this moment the scale mass death of conifers continues.
