THE SPREAD OF DISEASES IN VOLYN REGION FORESTS
Some peculiarities of expansion characteristics and general dynamics of the forest disease cores in Volyn region were studied in Volyn Regional Forestry and Hunting Industry Administration (VRFHIA). The dynamics of sanitary selective and solid felling with area distributions connected with VRFHIA in 2016 was illustrated. The main problems and tendencies of forest sanitary conditions were explained. The area of lesions the most dangerous forest diseases for 2016 if found to increase by 954.8 ha or 3.8 %. Having analysed Volyn region forest sanitary condition the authors have ascertained that generally 1220.5 ha of disease cores were eliminated by means of forest protection activities and written off during the report year. The biggest size is the concentration of Root fungus (Heterobasidion annosum (Fr.) Bref. 1889) and it remained the same as in the previous years. It covers 13961 ha or in other words it is 55 % of general surface of disease cores in this region. 5117 hectares need some methods of felling. Root fungus (Heterobasidion annosum (Fr.) Bref. 1889) has developed rapidly because of the long lasting drought season and the ground water level decrease. During 2016 Volyn RFHIA enterprises tried to solve the problem by solid sanitary felling in the areas of 332 ha with disease concentration. This is 2.4 % of the general land area of these nucleuses. The most common forest diseases are defined to be as follows: stem rot (Fomes fomentarius (L) Fr.1849) - 2363 ha; aspen fungus (Phellinus tremulae (Bondartsev & P. N. Borisov 1953) - 993 ha; diametrical Oak cancer (Pseudomonas quercus Schern.) - 922 ha; oak fungus (Daedalea quercina (L.) Pers.1801) - 676 ha; birch polyporus (Piptoporus betulinus (Bull.) P. Karst.1881) - 657 ha; red rot (Phellinus pini) - 562 ha; pitch streak (Cronartium flacci-dum (Alb. & Schwein.) G. Winter 1880) - 369 ha; alder fungus (Phellinus igniarius (L.) Quel. 1886) - 313 ha; bacterial ash cancer (Pseudomonas savastanoi (Janse 1982) Gardan, et al., 1992) - 216 ha; much smaller (Armillariella mellea (Vahl) P. Kumm. 1871) -183 ha. In order to protect and preserve forests when forestry proceedings, a complex of sanitary and recreational events and sanitary requirements are taking place.
Keywords: sanitary cuts; wood decay; sanitary condition of the forests; dynamics of diseases and pests; plantings affected by pathogens.
Introduction. Sanitary and sanatory events are the part of preventative measures that take place by the forest users in order to preserve stability of plants, prevention of development of pathological processes in the forest, decrease of damage that is caused by the pests, diseases, natural phenomena and technogenic effects (Manion, 1991; Cherubini et al., 2002). 539.7 ha of disease concentrations faded under the influence of natural factors. 2716.8 ha of new ones arose during the year (Turko et al., 2016).
Health-improving measures are established in order to protect and save forests. Health-improving measures are part of preventive treatment which is to keep the rigidity of forest crops, to prevent the development of pathological processes in the forest, to lower the harmfulness caused by insect pests, diseases, natural calamities and anthropogenic influence (Lonsdale et al., 2008).
Materials and Methods. The research was held on the basis of the standardized document in force and recommendations based on usage of sanitary investigation, the results of forest health monitoring and statistical data of forestry enterprises (Vorontsov, 1978; Sanitarni pravyla u lisakh Ukrainy, 1995; Anonimous, 2015). The general forest cove-
rage in relation to the land area is 34 %. The main forest forming species is Pinus sylvestris (L) and it constitutes about 63 % of the forested area, Betula (L.) (about 16 %) and Quercus (L.) (about 7 %).
The aim of this research is to study the functional features of disease agents' development in planted forests of Volyn RFHIA and to analyze their influence on general sanitary forest state. The object of the research is forest plantations of different ages infected by disease agents.
Results and Discussions. While analyzing the sanitary state of Volyn forests we can see that the dynamics of area, affected by forest pests, diseases and damages by abiotic factors is negative in forest pathological meaning. By the end of 2016 the land areas with the concentration of forest diseases have increased with 957 ha (3.9 %) as compared to the last year and constitutes 25.234 ha.The dynamics of sanitary selective fellings continues decreasing after 2010 (Fig. 1). According to the reported data the biggest amount of cubic meters of selective sanitary fellings was in 2010 and constituted 193.751 m3. In 2015 this number changed to 46.528 m3, which is four times less. The plan of sanitary fellings for 2016 was about 75.000 m3 of wood.

Fig. 1. Dynamics of the timber volume removed by selective sanitary fellings in Volyn RFHIA
Their amounts have significantly declined compared to the plan and constitutes 74 % (cubic measure). While sanitary selective fellings were conducted it was revealed that the selection of cubic measures from 1 hectare has increased with 0.7 m3/ha in comparison with the previous year.
Since 2005 and up to 2010 the amount of selective sanitary fellings has been continuing to grow. And since 2011 it has been constantly decreasing. By the end of the accounting period the smallest amount of fellings has been registered for the last 10 years. The amount of cubic meters that have been obtained from 1 ha in 2015 has also been the lowest for the last 10 years.
The dynamics of selective sanitary fellings is also characterized by the smallest amount of such ones conducted in the current year for the last 10 years (Fig. 2). And compared to 2009 it has become three times lower and equals 4286 ha. The delivery of this plan accounts for 64 %.
Fig. 2. Dynamics of the land area of selective sanitary fellings in Volyn RFHIA
The amount of solid sanitary fellings in 2015 is 1821 ha, which has reached the maximum point for the last 10 years (Fig. 3). Volyn region climate conditions are characterized by moderate continental climate with warm summers and mild winters, which is generally beneficial to the growth and development of the forests. The major factor of the deterioration in the condition of the forests and the decrease in forest expansion are weather changes. They became the cause of extreme climate conditions (drought or lowering of ground water level) which are frequent. The average precipitation level has decreased with 2.5 %, and the annual amount of effective temperatures with 1.7 % for the last 20 years (Vyshnevsky, 2014).
Fig. 3. Dynamics of the land area of solid sanitary fellings in Volyn RFHIA
There are several major reasons of forest crops plantation for selective sanitary fellings. Firstly, fires of the last years - 21.2 %. Secondly, a root fungus (Heterobasidion an-nosum) - 18 %. Thirdly, the fire in 2015 - 17 %. Also, minor flooding, marshiness, too much humidity, groundwater level fluctuation. Among other reasons there are diseases of forest plantations which provoke stem rot. Area distribution of solid sanitary fellings caused by different diseased and damages in Volyn RFHIA - 4.2 % windfall, 1.3 % honey mushroom, 1.8 % red rot, 18 % pine fungus, 7.6 % minor flooding, 21.2 % fires of the last years, 8.4 % groundwater level decrease, 1.9 % disfunctions caused by agricultural activities, 8.9 % groundwater level fluctuation, 8.4 % other reasons, 16.9 % fir fungus (Fig. 4).
Fig. 4. Area distribution of solid sanitary fellings caused by different diseases and damages in Volyn RFHIA
Insect pests are not taken into account because their amount is low and doesn't influence the research. The largest land area of fellings was held because of the fire reasons in the current year. Also the major factor is that the present year is characterized by the drought season. The increase of disease concentrations in the forest occurred mainly because of the root fungus nucleus (Heterobasidion annosum). The biggest disease area is a root fungus (Heterobasidion annosum). Its square area in comparison with the previous year has increased to 4.5 % and now it occupies 13.961 ha. In the current year 1590 ha of root fungus nucleus emerged (Heterobasidion annosum), and only 708 were eliminated by sanitary cuts.
This disease is in progression in pure plantations on barren soil. An important factor of the spread of this disease is

the creation of pine single-crop cultures on previously cultivated land and the critical age of this kind of disease. The crucial negative factor is the lack of attention of forest service to forestry enterprise in project management and sanitary examinations in the places of the low degree of damage. As a result, the massive attack of weakened trees (Ill -IV category of sanitary state) is being observed by hyperpa-rasites which cause negative influence on destabilization of forest pathological situation, especially the forest crops weakened by the root fungus (Heterobasidion annosum).
According to the sanitary examination reported data the biggest locations of root fungus (Heterobasidion annosum) were revealed in State Establishment "Starovyzhivske Forestry Enterprise" - 1665 ha, State establishment "Ma-nevytske forestry enterprise" - 2341 ha, State establishment "Liubeshivske Forestry and Hunting Enterprise" - 970 ha, State establishment "Kamin-Kashyrske forestry enterprise" - 810 ha, State establishment "Liubomolske Forestry Enterprise" - 1223 ha, State establishment "Ratnivske Forestry and Hunting Enterprise" - 882 ha, State establishment "Ratneagrolis" - 799 ha etc.
As well as in previous years, diseases that provoke stem rot - Aspen fungus (Phellinus tremulae (Bondartsev) (Bon-dartsev & Borisov, 1953), Birch polyporus (Piptoporus be-tulinus (Bull.) P. Karst., 1881), Red rot of pine and larch (Phellinus pini (Brot.) Bondartsev & Singer, 1941), Alder fungus (Phellinus igniarius (L.) Quel., 1886), Oak fungus (Daedalea quercina (L.) Pers. 1801) etc. have become widely spread. As to the data about Oak fungus (Daedalea quercina (L.) Pers. 1801), Birch polyporus (Piptoporus betuli-nus (Bull.) P. Karst., 1881), Alder fungus (Phellinus igniarius (L.) Quel. 1886), they defeat extraneous substance of main forest breeds where the age of technical ripeness was reached (in some cases it over ripped) and such trees as aspen, birch and alder degenerate.
Concerning the Red rot of pine and larch (Phellinus pini) and Oak fungus (Daedalea quercina (L.) Pers., 1801) the diseases are mainly spread in overriped wood. The age of main usage was prolonged because these forest crops were unexploited.
Aspen fungus (Phellinus tremulae (Bondartsev & Bori-sov, 1953) nucleus occupies 993 ha by the end of 2016, where 18 ha need some control measures. Red rot of pine and larch (Phellinus pini) nucleus occupies 562 ha by the end of 2016, where 248 ha need some control measures.
Oak fungus (Daedalea quercina (L.) Pers., 1801) nucleus occupies 676 ha by the end of 2016, where 230 ha need some control measures. Birch polyporus (Piptoporus betuli-nus (Bull.) P. Karst., 1881) nucleus occupies 657 ha by the end of 2016, where 283 ha need some control measures.
Stem rot (Fomes fomentarius (L.) Fr. 1849) nucleus occupies 2363 ha by the end of 2016, where 892 ha need some control measures. Diametrical Oak cancer (Pseudomonas quercus Schern.) nucleus occupies 922 ha by the end of 2016, where 328 ha need some control measures.
Alder fungus (Phellinus igniarius (L.) Quel., 1886) nucleus occupies 313 ha by the end of 2016, where 137 ha need some control measures. Pitch streak (Cronartium flaccidum (Alb. & Schwein.) G. Winter, 1880) nucleus occupies 369 ha by the end of 2016, where 92 ha need some control measures.
Bacterial ash cancer (Pseudomonas savastanoi (Janse, 1982) Gardan, et al., 1992) nucleus occupies 216 ha by the
end of 2015, where 114 ha need some control measures. Much smaller land area occupy such diseases as honey mushroom (Armillariella mellea (Vahl) P. Kumm., 1871) -183 ha, birch fungus (Lenzites betulina (L.) Fr., 1838) -84 ha etc.
Conclusions. After conducting our research, we can make the following conclusions:
1. The most influential factor on sanitary condition of Volyn forest ranges in 2016 was a long drought season which lead to the decrease of ground water level. The land area of weakened and drying plants has increased. Besides, a major harm was made to the forest plantations by heavy winds that were noted in the middle of the summer during the current year that happened on the territory of north-western forestry enterprises. Also, forest fires and their record square surface was noted and registered in the current year as well.
2. The lack of humidity can be noticed because of the long lasting period of the drought season proportionally on the whole territory of the region. The drought is revealed on small surfaces which is, probably, the result of the land form and the micro-climate where the drought takes place. During the year 2016, 321 ha of forest crops that have perished as a result of the ground water level lowering and the ground water level fluctuation were examined.
3. The drought of tertiary fir forest crops that have reached maximum age is also a global problem which characterizes Volyn forests sanitary state. This problem is mostly visible in southern forest regional enterprises. The drought is caused by the damage to the crops that arose as a result of root rot and massive invasion of pests. One of the drought reasons might be the fact that the territory of western Polissia isn't a natural habitat for pure pine tree plantations.
4. Root fungus (Heterobasidion annosum (Fr.) Bref. 1889) has developed rapidly because of the long lasting drought season and the ground water level decrease. During 2016 Volyn RFHIA enterprises tried to solve the problem by solid sanitary fellings in the areas of 332 ha with disease concentration. This is 2.4 % from the general land area of these nucleuses.
