Flestir landsmenn þekkja einhver kvæði sem Sigurður Þórarinsson jarðfræðingur hefur ort við grípandi lög eins og til dæmis „Að lífið sé skjálfandi lítið gras“ og „Þórsmerkurljóð,“ en færri vita að hann átti auðvelt með að kasta fram vísum og stökum við ýmis tækifæri ef svo bar undir. Þær einkenndust flestar af notalegri kímni en voru aldrei rætnar eða meiðandi. Ég ætla í þessu greinarkorni að birta nokkrar vísur eftir Sigurð og segja frá tilurð þeirra eftir því sem föng eru á.
Hlaup og gufusprengingar (jökulhlaup and phreatic explosions) í Kverkfjöllum í ágúst 2013
Authors: Guðmundsson Magnús Tumi , Einarsson Bergur , Oddson Björn
Published: February 2023

Í vorferð JÖRFÍ í byrjun júní fór hluti hópsins í Kverkfjöll. Skoðun á gögnum úr ferðinni leiddi í ljós að vatn var tekið að safnast fyrir í Gengissigi, jökulstíflaða lóninu austan við skála Jöklarannsóknafélagsins. Mælingarnar sýna að hækkun vatnsborðs frá haustinu 2012 hafði numið um 20 metrum. Samkvæmt myndum sem teknar voru eftir miðjan júlí hafði vatnsborð enn hækkað um 5 metra eða svo á þeim sex vikum sem liðið höfðu frá vorferðinni. Því var ljóst að hlaup gæti komið úr siginu innan árs héldi þessi þróun áfram. Þann 15. ágúst síðastliðinn urðu landverðir í Kverkfjöllum varir við að hlaup var í Volgu og sópaðist göngubrúin á ánni í burtu í þeim atgangi. Morguninn eftir var afráðið að kanna aðstæður og fór þyrla Landhelgisgæslunnar í Kverkfjöll með fólk frá Almannavörnum, Veðurstofu Íslands og Jarðvísindastofnun Háskólans. Eins og reiknað hafði verið með var Gengissigið hlaupið. Þétt dreif af uppbrotnum lagnaðarís þakti botn sigsins hvarvetna og vatnsborð stóð mjög lágt. En mesta athygli vöktu dökkar dreifar af leir sem náðu um 1 km norður fyrir sigið. Augljóst var að sprengingar höfðu orðið á nokkrum stöðum í norðanverðu siginu í lok hlaupsins og efnið sem upp kom myndað dreifarnar.
Shallow geothermal and deep seismicity beneath Þeistareykir, NE Iceland
Authors: Schuler Juerg , White Robert S. , Brandsdóttir Bryndís , Tarasewicz Jon
Published: February 2023

The seismicity in the central Þeistareykir volcanic system, NE Iceland, between 2009–2012 consists of spatially clustered earthquakes at 2–5 km depth (b.s.l.) southwest of the main geothermal fields. Deep earthquakes are located in a scattered pattern southeast of Þeistareykir at 8–20 km depth (b.s.l.). Although not associated with detectable surface uplift they may be caused by high strain rates within the plastic regime of the crust in the vicinity of the Húsavík-Flatey transform fault system or due to reduced normal friction caused by melt movements at depth.

Published: February 2023

Umtalsverðar land- og jökulbreytingar urðu við Hoffellsjökul í Nesjum haustið 2015. Þær tengdust mikilli úrkomutíð í október eða snemma í nóvember sem olli snöggum vexti dragáa í Hoffellsnúpum (Núpum) og Efstafelli, á milli Hoffellsjökuls og Lambatungujökuls. Töluvert rof varð úr farvegum ánna í grennd við jökullónin Múlavatn og Gjávatn við Hoffellsjökul. Á sama tíma hvarf Gjávatn og sú spurning vaknar hvort vatnavextir hafi hrint af stað hlaupi úr lóninu svo að það tæmdist. Engum sögum fer þó af hlaupvatni í Hornafjarðarfljótum enda vötnin smá og óvíst hvort hægt hefði verið að aðgreina hlaupvatn frá öðrum vatnavöxtum í kjölfar úrkomutíðarinnar. Gervitunglamyndir sýna jafnframt að á sama tímabili hafa jakar brotnað upp í lóninu framan við Hoffellsjökul, þótt það kunni að hafa stafað af öðru en jökulhlaupinu.
Extension of the Middle Miocene Kleifakot geomagnetic instability event in Ísafjörður, Northwest Iceland
Authors: Kristjánsson Leó
Published: February 2023

Detailed records of past geomagnetic polarity transitions and excursions are seldom found in extrusive volcanics. One type of such events seems to involve very irregular variations of the magnetic field direction. Several examples of that type have been discovered in paleomagnetic surveys on the Neogene lava pile of Iceland. Lava sequences spanning the most notable event are accessible in the two tributary fjords Mjóifjörður and Ísafjörður south of Ísafjarðardjúp, Northwest Iceland. Paleofield direction results from about 80 sampling sites in these sequences have been described in previous publications. The present paper adds 20 sampled sites in Ísafjörður, extending the area where parts of this „Kleifakot instability event“ of the geomagnetic field are recorded, to 5–6 kilometers along the fjord. Intermediate paleofield directions in the collection often agree closely with each other in correlated strata, even more than 4 kilometers apart. Events like this can provide valuable correlation tools for future stratigraphic mapping and various studies on volcanological features in the relatively uncharted region around Ísafjarðardjúp and beyond. Globally, recognition of the existence of such events will aid in the interpretation of results in other kinds of paleomagnetic studies. The role of geomagnetic paleo-intensity determinations is discussed briefly in this context.

Hekla volcano is known to have erupted at least 23 times in historical time (last 1100 years); often producing mixed eruptions of tephra and lava. The lava flow volumes from the 20th century have amounted 80\% to almost 100\% of the entire erupted volume. Therefore, evaluating the extent and volume of individual lava flows is very important when assessing the historical productivity of Hekla volcano. Here we present new maps of the historical lava flow fields at Hekla in a digital format. The maps were produced at a scale of 1:2000–10000 using a catalogue of orthophotos since 1945, acquired before and after each of the last five eruptions, combined with field observation of stratigraphy, soil profiles, tephra layers and vegetation cover. The new lava flow maps significantly improve the historical eruptive history of Hekla, prior to the 1947 eruption. The historical lava flow fields from Hekla cover ∼233 km² and the lavas reach up to 16 km from Hekla volcano. Flow lengths up to 20 km are known, though lava flows only travelled up to 8–9 km from Hekla in the last 250 years. Identified historical vents are distributed between 0 and 16 km from Hekla volcano and vents are known to have migrated up to 5 km away from Hekla during eruptions. We have remapped the lava flow fields around Hekla and assigned the identified flow fields to 16 eruptions. In addition, ca. 60 unidentified lava units, which may be of historical age, have been mapped. It is expected that some of these units are from known historical Hekla eruptions such as the 1222, 1341, 1510, 1597, 1636 and potentially even from the previously excluded eruptions such as 1436/1439.

Þar skoðaði ég eldfjöll á megineyjunni, og dr. George P. L. Walker (1926–2005) sýndi mér nokkra áhugaverða staði með hraunum og göngum á Oahu. Walker sendi mér seinna vélritað bréf dagsett 13. júlí 1990, um sérstakt áhugamál sitt varðandi Ísland, eins og ég hef nefnt áður (Kristjánsson, 2005). Áhugamálið snerist um þétta sveima hallandi innskota sem sjást í berggrunni víða milli Breiðamerkurjökuls og Álftafjarðar á Suðausturlandi. Hann og A. E. Annels höfðu kannað þá á árunum 1962–66.

Ljósmyndir Þorláks Sverrissonar í Vík: Kötlugosið 1918 í nýju ljósi
Authors: Larsen Guðrún , Högnadóttir Þórdís
Published: February 2023

Þorlákur Sverrisson kaupmaður í Vík í Mýrdal tók ljósmyndir af Kötlugosinu 1918 „frá byrjun til enda“ svo vitnað sé í hans eigin orð. Raunvísindastofnun fékk 18 glerplötur að gjöf frá erfingjum hans og eftirmyndir af 17 þeirra birtast hér ásamt skýringum og tilraun til tímasetninga. Ef tímaröðin, sem hér er kynnt, er nærri lagi eru myndirnar teknar frá 12. október til 2. nóvember 1918. Samkvæmt henni var fyrsta myndin tekin í Víkurþorpi 12. október, á fyrsta gosdegi og sýnir gosmökk vofa yfir húsunum. Önnur mynd frá sama degi var tekin norðan Víkur og sýnir háan gráleitan mökk yfir Höttu. Þessar tvær gætu verið fyrstu myndir í heiminum sem teknar voru af sprengigosi í jökli. Eftir fyrstu þrjá dagana sljákkaði í gosinu. Fjórar myndir sem sýna lægri gosmökk, meðal annars tvo aðgreinda gosmekki upp úr jöklinum, voru teknar á tímabilinu 15. til 20. október. Mekkirnir eru hvítir að sjá á myndunum og virðast að mestu vatnsgufa. Mynd frá 22. október sýnir dökkgráan öskumökk yfir fjöllunum norðan Víkur, rétt áður en hann fór að hrynja yfir fjallabrúnirnar og aska fór að falla í þorpinu. Mynd frá 24. október sýnir dökkan mökk yfir Höttu kolsvartri af ösku og einnig virðast upptök makkarins nú austar en áður. Öskufall hófst í Vík síðdegis þann dag og stóð í 13 klst. Fjórar myndir voru teknar 2. nóvember, síðasta daginn sem verulegur gosmökkur sást. Auk mynda af gosmekki tók Þorlákur myndir af hlaupfarvegum og ísgljúfri sem varð til þegar jökulhlaup braust fram undan/úr jaðri Kötlujökuls og braut a.m.k. 1300 m langt og allt að 300 m breitt skarð í hann. Myndir Þorláks eru þær einu sem þekktar eru af þessu gljúfri. Vísindalegt gildi myndanna er töluvert og í þeim eru meiri upplýsingar en dæmin sem tekin eru hér. Þær sýna breytileikann í sprengivirkninni og staðfesta færslu gosstöðvanna meðan á gosinu stóð. Hægt er að reikna hæð gosmakkar og miða út upptök hans. Þær sýna hlaupfarvegi á Mýrdalssandi og hægt er að meta flóðmörk meginhlaupsins á ofanverðum sandinum. Sumar myndanna hafa látið á sjá en með nútímatækni er hægt að laga þær og skerpa og nýta til fulls.
Eysteinn Tryggvason – minning (in memoriam)
Authors: Einarsson Páll
Published: February 2023

Eysteinn Tryggvason jarðeðlisfræðingur lést 11. janúar 2021, í hárri elli. Hann fæddist á Litlulaugum í Reykjadal 19. júlí 1924 og ólst þar upp í stórum systkinahópi. Foreldrar hans voru Tryggvi Sigtryggsson og Unnur Sigurjónsdóttir. Hann varð stúdent frá Menntaskólanum á Akureyri 1946 og fór til náms í veðurfræði og skyldum greinum við Oslóarháskóla 1946. Þaðan lauk hann cand. real. prófi 1951. Ekki átti það þó fyrir honum að liggja að starfa við veðurfræði, því að námi loknu varð það verkefni hans að sjá um jarðskjálftamælingar Veðurstofu Íslands. Það olli straumhvörfum á ferli hans að ráðning hans á Veðurstofunni dróst um hálft ár vegna kröftugra mótmæla Bandarískra stjórnvalda að hann fengi að starfa við veðurfræði á Keflavíkurflugvelli. Á þessum tíma var Veðurstofan að taka yfir veðurfræðilega þjónustu við millilandaflug frá Keflavík. Hann varð deildarstjóri jarðeðlisfræðideildar VÍ 1952–1962 og sá m.a. um bókasafn stofnunarinnar. Á þessum árum urðu nokkur þáttaskil í starfinu, mælitæknin tók framförum og Veðurstofan tók upp nokkur samvinnuverkefni við erlendar stofnanir, meðal annars við Háskólann í Uppsölum. Þetta varð til þess að Eysteinn fór þangað til framhaldsnáms í jarðeðlisfræði. Eysteinn lauk þar fil. lic.-gráðu 1961. Að námi loknu fluttist hann til Oklahoma og gerðist prófessor í jarðeðlisfræði við Háskólann í Tulsa. Þar starfaði hann í 13 ár við kennslu og rannsóknir. Ísland togaði þó alltaf í hann, og talsverður hluti rannsókna hans beindist að ferlum í jarðskorpunni hér á landi. Þegar svo starfsemi á þessu sviði við Háskóla Íslands óx fiskur um hrygg, sótti hann um dósentsstöðu og starfaði við Verkfræði- og raunvísindadeild 1975–1977. ...

International Universal Health Coverage Day is celebrated on December 12. In the above format, the relevance of the work of trained nursing staff as the largest sector in the provision of primary health care (PHC) to the population is undeniable. The issues of mutual adaptation of personnel in the format of healthcare itself and the education of competitive specialists in terms of PHC with the direction of activity along the vector of the economic system and the medical «labor market», as well as the registration of the satisfaction of the population and the trained medical staff are the basis for improving training through the creation of innovative programs. The study identified the areas for reforming the educational process of the nursing staff — nurses and medical assistants providing population with primary health care.

Published: February 2023

У пациентов, перенесших открытую реваскуляризацию миокарда в условиях искусственного кровообращения (ИК), одним из осложнений является когнитивная дисфункция. Цель работы - изучение влияния интраоперационного лактат-ацидоза, анемии и длительности аноксии миокарда на изменение когнитивного статуса у больных пожилого возраста при помощи FAB после операции аортокоронарного шунтирования (АКШ) с ИК. Было доказано негативное влияние лактат-ацидоза на когнитивный статус у пациентов пожилого возраста после АКШ. Определена зависимость между снижением концентрации гемоглобина во время операции и отрицательной динамикой когнитивных изменений в послеоперационном периоде (R=0,41; p=0,021). Выявлено негативное влияние длительной аноксии миокарда во время операции на динамику когнитивных функций у больных пожилого возраста, перенесших АКШ с ИК. Таким образом, вышеперечисленные показатели могут являться маркерами формирования послеоперационной когнитивной дисфункции.

In patients undergoing open myocardial revascularization under cardiopulmonary bypass (CB), one of the complications is cognitive dysfunction. The aim of the work is to study the effect of intraoperative lactic acidosis, anemia and the duration of myocardial anoxia on the change in cognitive status with the help of FAB after coronary artery bypass grafting (CABG) with CB. The negative impact of lactic acidosis on cognitive status in patients after CABG has been proven. The relationship between the decrease in hemoglobin concentration during surgery and the negative dynamics of cognitive changes in the postoperative period (R=0,41; p=0,021) was determined. A negative effect of prolonged myocardial anoxia during surgery on the dynamics of cognitive functions of patients was revealed. Thus, the above indicators may be markers of the formation of postoperative cognitive dysfunction in patients undergoing CABG with CB.
Teacher-student verbal communication and student learning

Published: February 2023

Teachers and students communicate through curiosity and attention. In social psychology, the instructor communicates and the pupil receives. Teaching-learning involves students getting teaching materials in various forms and teachers offering them in a dialogic style at a given time and location. Teacher-student contact is essential for effective teaching and learning. Teachers and students exchange psychological messages. Student learning achievement is multifaceted. Teachers' verbal communication skills affect student learning. Verbal communication—spoken or written—uses symbols or words. Teachers require solid language skills and a vast vocabulary to speak verbally because kids cannot understand specific words alone. This study seeks to understand how teacher verbal communication is implemented, how student learning is affected, and how. The association between verbal communication (variable X) and student learning success (variable Y) is researched using a quantitative descriptive method using a correlational study type, Product Moment (r). This strategy examines how components are connected.

A study based on the results of the treatment of patients with chronic hemorrhoids who were treated from January 2021 to January 2022 was conducted based on the surgical department of the RDC and MIPO Clinics LLP. The study included 100 patients aged 21 to 72 years with chronic hemorrhoids of stage II and III, in the treatment of which the method of hemorrhoidectomy with PRP therapy (main group) and open hemorrhoidectomy (control group) was used. In the analysis of clinical efficacy, the severity and duration of pain syndrome, manifestations of complications in the early postoperative period, cytomorphological analysis of fingerprint smears, the number of bed days spent, and the period of recovery were used. An analysis of the assessment of the quality of life of patients after surgery in the long-term period was also carried out. Results. The intensity of pain severity was estimated at an average of 3±0.2 points in the main group and 6.1±0.3 points in the control comparison group. The duration of pain continuation after surgery averaged 3.1±0.2 days in the main group and 4.4± 0.2 days in the control comparison group. The development of early postoperative complications in the main group – in 6 (12%), in the control group were diagnosed in 14 (28%) cases. When assessing the dynamics ofthe wound process according to the cytological picture, it was noted that the neutrophil reaction was more pronounced in the control group. In the main group, epithelization elements appeared faster (from the 10th day - in 35%). The average epithelialization time was 31.1±2.2 days in the control group compared to 20.3±3.9 days in the main group. In the main group, by day 15, 31 (62%) patients and by day 25, 50 (100.0%) all patients returned to work. In the control group, 32 (64%) patients started working by day 30 and 100% by day 40. Conclusion. Taking into account the results of the study, the use of an integrated approach with the use of PRP therapy in the treatment of chronic hemorrhoids is recommended. It is shown that the use of the proposed patented treatment regimen leads to a decrease in postoperative pain syndrome, accelerated wound healing, and a decrease in the number of complications.

The experiment aimed to evaluate the effect of organic manure on the growth and yield of carrots (Daucus carota L.) grown in Jos and Makurdi Benue State, Nigeria. The treatments used were organic manure sources (Poultry dropping (20t/ha), Cow dung (20t/ha), Goat manure (20t/ha), dung site (20t/ha) and control (zero application and) the spacing used between plants and rows were 15 and 75cm, respectively. The experiment was laid in a randomized complete block design with three replications. During the investigation, some physiological variables, such as plant height and the number of leaves were measured. Other characteristics like aerial weight, root weight, root length, rot diameter, harvest index and over-all yield were also recorded. The results of the investigation revealed that carrot responded to nutrient sources with poultry dropping and Jos producing better in both growth and yield parameters. All the parameters studied significantly (P ≤ 0.05) responded to nutrient source with poultry dropping been superior in both growth and yield-related characters such as plant height at 8WAT (32.20), the number of leaves 8WAT(122.20), aerial weight (10.27g), root weight (18.02g), root length(12.81cm), root diameter (4.00mm), harvest index (0.71) and over-all yield (5.10t/ha). Carrot grown in Jos outgrows those cultivated in Makurdi in both growth and yield-related character. Based on the results obtained it could be suggested that the use of poultry dropping which is better in both growth and yield characteristics will lead to optimum yield in carrot cultivation in the study areas.

The article presents the results of research, evaluation and analysis of elements of landscaping of Vinnytsia National Agrarian University. The university complex is one of the main elements of the urban environment, which requires a special attitude and place in the planning and organizational structure of the city. The environment should provide students and teachers with optimal conditions for fruitful educational and scientific activities and a variety of recreation, sports. It has been established that the territory of the university has a clear combination of buildings connected by passages into a system that provides opportunities for a harmonious combination of buildings and greenery. The proportions of individual groups of buildings, their plastic solution and spatial development in the depth of the site, the combination of open and closed spaces, extensive use of green courtyards and small architectural forms give unity and beauty to the architectural ensemble of higher education. It is investigated that pedestrian traffic is correctly organized during the design of the complex. The central esplanade is located and arranged in such a way that it connects all the zones and ensures their interconnection and at the same time is a place for students to communicate. It is estimated that alleys and paths in the park zone of VNAU occupy about 20% of its area. Forced curves are used to create a variety of accents, such as trees and shrub groups. There are 5 classes of roads, paths and sites on the territory of the university, the condition of which is excellent. According to the analysis of landscaping elements, there are 34 benches for long-term rest and 14 benches for short-term rest near the university buildings. All presented benches are stationary and made of concrete, wood and brick. This number of benches is sufficient to ensure comfortable living conditions for students in all corners of the university. The benches are easy to use, their shape is simple, and the color organically fits into the overall color scheme of the territory.

Published: February 2023

In order to study the impact of a comprehensive system of drugs of bacterial origin, the company BTU-Center monitored biometric indicators and productivity of sweet pepper in the open ground of the Right Bank forest-steppe of Ukraine. The early-ripening variety of sweet pepper Aphrodite was used for research. Organic cultivation technology was used in the experiment. Dosing of biological products was carried out according to the manufacturer's recommendations, and the dose of drugs was doubled. Biometric parameters varied depending on the dose of biological products. During the growing season, the height of the plants of the control variant was 32.1 cm, but with the use of the recommended dose of biological products, the height of the plant was 35.3 cm, which is 3.2 cm higher than the control variant. The use of a double dose of biological products provided the highest rates of plant height. The larger diameter of the stem was obtained by applying a double dose of biological products - 8.5 mm. As a result of the use of biological products, the stem diameter exceeded the control variant by 0.8 and 0.9 mm, respectively. In studies, the fruits in all respects corresponded to the technical characteristics of the variety, but their weight was variable. The highest average fruit weight was characterized by plants using a double dose of biological products - 138.9 g. The study indicators exceeded the fruit weight of the control variant by 9.1 and 10.4%. The highest average yield was obtained with a double dose of biological products - 26.4 t / ha. In these variants, the excess yield relative to control was 9.3 and 11%, respectively. As a result of the application of the recommended dose of biological products, the stability of Lewis was - 1.18, and with the use of a double dose - 1.16. The use of organic technology in open ground significantly improves the biometric performance of sweet pepper plants. The use of organic cultivation technology increases the number of fruits per plant, but doubling the dose of biological products does not give a significant advantage over the recommended application rates.
THE INFLUENCE OF EXTRA-ROOT NUTRIENTS ON THE DURATION OF THE INTERPHASE PERIOD OF SPRING BARLEY IN THE CONDITIONS OF THE RIGHT-BANK FOREST STEPPE OF UKRAINE
Authors: Tkachuk Oleksandr
Published: February 2023

A sufficient amount of precipitation and a moderate air temperature are necessary for optimal growth and development processes, as well as the formation of reproductive organs of plants. Since their excessive or insufficient amount, as well as elevated or low temperature conditions, delay or accelerate the passage of interphase periods and adversely affect the duration of vegetative and generative growth of spring barley plants. In the course of research, it was established that in order to reduce the negative impact of the weather conditions of individual years on the stability of the gross harvest of barley grain, it is necessary to carry out foliar feeding in the phase of tillering and emergence of plants into the tube with biological preparations, such as Help Rost - 2 l/ha, Organic D2-M - 1 l/ha, Azotophyte - 2 l/ha. The duration of the period of earing-full ripeness turned out to be the most contrasting in response to the application of fertilizers. Thus, in the variant with the introduction of mineral fertilizers in the dose of N15Р15К15 and with one-time treatment with biological preparations Help Rost 2 l/ha, Organic D2-M 1 l/ha, Azotophyt 2 l/ha, the duration of this period was extended by 1 day compared to the control variant and by 2 days for two-time feeding with the indicated preparations in the phase of tillering and emergence of plants into the tube. So, in general, the duration of the growing season in spring barley varieties Armaks and Swagor on the control variant were the lowest and amounted to 83 and 79 days, respectively.By carrying out one-time foliar fertilization in the budding phase with biological preparations Help Rost - 2 l/ha, Organic D2-M - 1 l/ha, Azotophyt 2 l/ha against the background of N15Р15K15 fertilizer, the length of the growing season was extended to 85 and 86 days and 81 and 82 days , it is higher than on the control variant by 2 and 4; 2 and 3 days, respectively. With a two-time foliar feeding in the phase of bushing and emergence of plants in the tube with biological preparations Help Rost - 2 l/ha, Organic D2-M - 1 l/ha and Azotophyt 2 l/ha against the background of N15Р15K15 fertilizer, the duration of the growing season was extended to 86 and 87 days.

As a result of the research, it was established that as of 2021, 126 oak trees, 5 European larch trees, and 2 European spruce trees have been entered into the state register in the Vinnytsia region. It was determined that, on average, the potential seed collection for common and northern oak is: 400-700 kg/ha, black walnut – 600-800 kg/ha, broad-leaved linden – 80-160 kg/ha, edible chestnut – 400-700 kg/ha. It was established that the total number of LGR entered in the Register is 46 plots with a total area of 1,286 hectares. According to the results obtained in 2020 and 2021, about 8,000 kg of seeds were harvested in the plantations of the LHR, which is 6 % of the total harvest of acorns in the region. In 2021, an inventory of 133 positive trees selected in the Vinnytsia region was carried out. In terms of the main tree species, these are: oak trees – 126 pcs., European larch – 5 pcs., European spruce – 2 pcs. The average age of plus trees is 88-131 years. It was determined that the area of LPN of common oak in Vinnytsia region is 530.3 ha. The average age of the plantations is 77 years. According to the received tabular data, it was established that the largest areas of LNP are represented by common oak – 57.6 hectares out of 63.1 hectares. It should be noted that in this case, the number and area of LNP, which entered the fruiting period and were certified, are given. In the conditions of Vinnytsia, the PLNB also includes a pine plantation and three European larch plantations, the area of which is 1.0 ha and 3.0 ha, respectively. As a result of the last inventory, it was established that the total number of permanent forest seed plots is 116, the area of which is 1225.2 ha. The largest number and the corresponding area occupied by the PLAND of ordinary oak is, respectively, 87 pcs. and 1115.5 ha. As a result of the conducted scientific research, Scots pine, Pallas pine, rock oak, European larch, Menzies pseudotsuga, Weymouth pine, and chestnut oak are not used for the collection of PLND seeds. 21 % of the total number of PLNDs of common oak, 15 % of red oak, 8 % of black walnut require selective care and other care. After analyzing the selection structure and condition of the Weymouth pine trees (SE «Vinnytske LG», Ivanivsk L-vo, passport No. 4, square 30, view 16, area 1.0 ha, age 113 years, certified in 1965) on the PLND was an unsatisfactory selection structure and condition of the specified trees was established.
