“…Due to these reasons, on the account of podzol soils deoxidation their fertility has increased and furthermore, volume increment for every square unit has also increased. Zavyalov et al (2019) emphasized that the annual growth rings of Scots pine on fertile soils were significantly higher than those of on poor soils. Also, soil fertility allows better adaptation of Scots pine to low temperatures, and more actively grow on sites with increasing precipitation in technogenic areas.…”

Since the middle of the last century in the Urals of Russia there has been a problem of environmental pollution by man-made emissions. The purpose of this investigation has been to summarize the recultivation experience of Reftinskaya power plant ash dump. The station was put into operation in 1970 and it is the largest one in Russia. Specific feature of the used coal is high content of ash (47%). Daily consumption of coal in winter period constitutes 48 thousand tons. Yearly emissions of the station constitute 400 thousand tons. The main components of the emissions are sulphureous anhydride (up to 40%) solid stuff (up to 50%) and nitric oxides. The Scots pine (Pinus sylvestris L.) plantations on ash dumps have shown good adaptation and growth. The plantations have formed 143 m 3 /ha total volume at the age of 20 in 1 st site index of the recultivation site of the ash dump with ash layer up to 7 m. Weakly alkaline reaction of the ash spread by wind promoted soil dioxidation that results in soil fertility increasing significantly on territory of adjacent stands. Recultivation process includes two main stages which are ash dump surface covering with 25-40 cm soil layer, planting with 2-year old Scots pine (Pinus sylvestris L.) seedling.

“…Исследования проведены в ценопопуляциях сосны обыкновенной (Pinus sylvestris L.), произрастающих в условиях влияния выбросов крупных промышленных предприятий Урала: комбината «Магнезит», Среднеуральского медеплавильного завода (СУМЗ), Полевского криолитового завода (ПКЗ). В районе каждого источника аэротехногенных выбросов заложены опытные участки (ОУ) и постоянные пробные площади (ППП), на которых научные сотрудники лаборатории экологии техногенных растительных сообществ Ботанического сада УрО РАН ведут многолетние исследования состояния растительного покрова, вегетативной и репродуктивной систем сосны, содержания токсичных элементов в снеге, почве и лесной подстилке (Махнева, 2017;Mohnachev P. et al, 2018;Zavyalov et al, 2018;Makhniova et al, 2019).…”

Приведены результаты исследования основных показателей качества семян сосны обыкновенной (Pinus sylvestris L.), произрастающей в условиях воздействия аэротехногенного загрязнения трех крупных промышленных предприятий Среднего и Южного Урала, характеризу- ющихся разными по типу и химическому составу выбросами. Выявлено снижение массы семян в импактных зонах магнезитового (ПАО «Комбинат Магнезит») и медеплавильного производств (ПАО «СУМЗ»). В условиях импактной зоны комбината «Магнезит» происходит существенное увеличение (в 1,8–2,9 раза) индивидуальной изменчивости показателя массы 10 00 семян относительно фоновых условий, а также импактных зон СУМЗа и криолитового (ПКЗ) заводов. Возможными причинами могут являться снижение охвоенности и продолжительности жизни хвои, ухудшение санитарного состояния древостоя, а также воздействие аэрополлютантов на ростовые процессы в семяпочках. В настоящее время отмечено возрастание энергии прорастания и всхожести семян сосны обыкновенной, произрастающей в условиях влияния выбросов СУМЗа и ПКЗ, что связано со снижением текущего объема аэротехногенных выбросов указанных предприятий. В условиях аэротехногенных выбросов комбината «Магнезит» данные показатели находятся, как и ранее, на высоком уровне. Таким образом, в условиях влияния современного объема выбросов всех изученных промышленных предприятий энергия прорастания и всхожесть семян сосны обыкновенной находятся на уровне условий фона и видового уровня в целом. The results of the study of the main indicators of the quality of the seeds of scots pine (Pinus sylvestris L.), growing under the inﬂ uence of aerotechnogenic pollution of three large industrial enterprises of the Middle and Southern Urals, characterized by emissions of different types and chemical composition, are presented. A decrease in seed weight was revealed in the impact zones of the magnesite (PJSC “Magnezit Combine”) and copper smelting industries (PJSC “SUMZ”). In the conditions of the impact zone of the Magnezit combine, there is a signiﬁ cant increase (by 1,8–2,9 times) in the individual variability of the mass index of 1000 seeds relative to background conditions, as well as the impact zones of the SUMZ and cryolite (PCP) plants. Possible reasons may be a decrease in the number of needles and the life expectancy of needles, deterioration of the sanitary condition of the stand, as well as the effect of aeropollutants on the growth processes in the ovules. At present, there has been an increase in the germination energy and germination of the seeds of scots pine, growing under the inﬂ uence of emissions of SUMZ and PCP, which is associated with a decrease in the current volume of aerotechnogenic emissions of these enterprises. In the conditions of aerotechnogenic emissions of the Magnezit combine, these indicators are at a high level as before. Thus, under the inﬂ uence of the current volume of emissions of all studied industrial enterprises, the germination energy and germination of the seeds of scots pine is at the level of background conditions and the species level as a whole.

“…The climate change problem is one of the most frequently discussed topics in the modern scientific literature, since ecosystem biodiversity, stability, and ecological functions are predicted to face major changes as a result of global climate changes across all continents [1,2], increasing risks for the regional and global environmental crises and a loss of favorable habitat for humans [3]. Climate change can also exacerbate the effect of other factors on vegetation, as is the case with man-made pollution [4,5]. In this regard, the climate-vegetation problem is recognized as one of the most urgent in ecology and biogeography [1,2,[6][7][8][9][10][11].…”

Climate is one of the key drivers of the plant community’s structure and trends. However, the regional vegetation-climate features in the ecotone have not yet been sufficiently studied. The aim of the research is to study features of Pinus sibirica Du Tour germination, survival, and growth in the mountain tundra of the Northern Urals against the background of a changing climate. The following research objectives were set: To determine the abundance and age structure of P. sibirica undergrowth on the mountain tundra plateau, identify the features of P. sibirica growth in the mountain tundra, and examine the correlation between the multi-year air temperature pattern, precipitation, and P. sibirica seedling emergence. A detailed study of the Pinus sibirica natural regeneration in the mountain stony shrub-moss-lichen tundra area at an altitude of 1010–1040 m above sea level on the Tri Bugra mountain massif plateau (59°30′ N, 59°15′ E) in the Northern Urals (Russia) has been conducted. The research involved the period between 1965 and 2017. Woody plant undergrowth was considered in 30 plots, 5 × 5 m in size. The first generations were recorded from 1967–1969. The regeneration has become regular since 1978 and its intensity has been increasing since then. Climate warming is driving these processes. Correlation analysis revealed significant relationships between the number of Pinus sibirica seedlings and the minimum temperature in August and September of the current year, the minimum temperatures in May, June, and November of the previous year, the maximum temperatures in May and August of the current year, and precipitation in March of both the current and previous years. However, the young tree growth rate remains low to date (the height at an age of 45–50 years is approximately 114 ± 8.8 cm). At the same time, its open crowns are rare single lateral shoots. The length of the side shoots exceeds its height by 4–5 times, and the length of the lateral roots exceeds its height by 1.2–1.5 times. This is an indicator of the extreme conditions for this tree species. With the current rates of climate warming and the Pinus sibirica tree growth trends, the revealed relationships allow for the prediction that in 20–25 years, the mountain tundra in the studied Northern Urals plateau could develop underground-closed forest communities with a certain forest relationship. The research results are of theoretical importance for clarifying the forest-tundra ecotone concept. From a practical point of view, the revealed relationship can be used to predict the trend in forest ecosystem formation in the mountain forest-tundra ecotone.
