The actuality of the research is caused by the importance of understanding the laws of natural distribution of woody and shrub plant species on devastated lands of iron ore dumps of Kryviy Rih as a theoretical prerequisite for harmonizing the ecological environment of industrial regions. The aim of the research is to assess the current vital condition of woody and shrub plant species that naturally grow on devastated lands of the iron ore dump from the standpoint of the ecosystem approach. The materials of the work were the results of our own research, which were carried out according to generally accepted methods during 2020–2021 on the territory of Petrovsky waste rock dump of Kryviy Rih iron ore basin. The assessment of the current vital condition was carried out according to the method of V. A. Alekseyev. Presently,   the vegetation on Petrovsky waste rock dump, which is a model for the region, is represented by natural groups, has a fragmented character and is a sparse forest. It has been established that 32 species of woody and shrub plant species (25 genera and 15 families) naturally grow within Petrovsky waste rock dump. The current vital condition of woody and shrub plant species in the dump was assessed as «weakened» (65–71 conventional points by V. A. Alekseyev’s scale). Such numerical values of the vitality of the forest stand are 21–28% lower than the control indicators (natural groupings of Gurivka forest). Our results indicate that the ecological conditions of the devastated lands of Petrovsky waste rock dump are relatively favourable for the growth and development of woody and shrub plant species. It was found that European birch (Betula pendula Roth.), ash-leaved maple (Acer negundo L.) and acacia (Robinia pseudoacacia L.) are quite adapted to the habitat conditions of the dump. The vital condition of these species was assessed as «healthy»: 90–95 conventional points by V. A. Alekseyev’s scale.

Waste Rock Dump

This research was performed at Petrovsky waste rock dump, the Central part of the Kryvyi Rih iron-ore & metallurgical district (Dnipropetrovsk region, Ukraine). The macronutrients (K, Ca, Mg, P and S) and heavy metals (Fe, Mn, Zn, Cu, Pb and Cd) contents in the leaves of three species of the trees (Ash-leaved maple, Silver Birch and Black locust) that were collected on devastated lands were assessed. It was established that trees which grow on the Petrovsky dump take place under evident shortage of nutrients (especially K and P) and excess of metals (especially Fe, Mn and Zn). It is revealed that Ash-leaved maple and Black locust are more resistant to the geochemical conditions of devastated lands. In this regard, these species of trees can be recommended for forest restoration & reforestation on devastated lands.

The paper presents the floristic diversity of the left bank of the Danube and the canal network of Krnjaca and Borca settlements, as well as the factors that endanger it. 216 autochthonous and allochthonous plant species were recorded in the investigated area. A large number of invasive plant species have been observed that spread rapidly and easily forming stable populations that displace native plants. Some of them are: Amorpha fruticosa L., Robinia pseudoacacia L., Ailanthus altissima (Mill.) Swingle, Asclepias syriaca L., Ambrosia artemisiifolia L. and others. The presence of 6 species that are rare and endangered in Serbia is especially significant, as well as 5 relict species. During the investigation, the factors which influence on natural habitats degradation and the reduction of autochthonous floristic diversity were identified. Accordingly, measures for protection and preservation of autochthonous floristic diversity are recommended.

A large amount of heavy metals leads to environmental pollution. Heavy metals are part of the land or may arise as a result of human products. Affecting the normal growth and development of plant systems and only to a certain limit concentrations of metals. Increasing these suitable and permitted a value to metals in the soil leads to changes in the composition and appearance of the environment in a negative direction. To eliminate or reduce elevated concentrations of heavy metals and their adverse effects on the environment, many researchers focus their attention on finding species that can act as scavengers soil and phytoremediations. There are a large number of plant species that are capable of survival on such surfaces, whether it comes to wild species or species that are on the site with the aim planted. The best known and the most common fitoremedijatori by woody species are Acacia (Robinia pseudoacacia L.) and its most closely related to indigo ( Amorpha fruticosa L.). Its advanced adaptation and the possibility of survival in the soil rich with heavy metals, are plant species that are used in order to protect the environment from the adverse effects of heavy metals. These species have developed ability to adapt, and thereby can perform the accumulation of heavy metals from the soil. They absorb these metals or through the root system, through the tree to the leaves and flowers or leaves through the metal while returning the return direction. In this way, that is, the accumulation of metals that are present in concentrations higher than allowed for stay vegetation, stored and purified by environmental influences damaging of elements which are present in the air and in the soil.

Works on protective afforestation are carried out in order to protect agricultural land from degradation processes, as well as to improve the microclimate of land. The research purpose is to study the bioproductivity and environmental role of Robinia pseudoacacia L. forest shelterbelts in the conditions of the Kuban lowland. The approved and generally accepted methods of forest valuation, forest land reclamation, botany, and mathematical statistics were applied. Plantings were created according to the standard technology for the steppe zone of the Russian Federation. The area of forest shelterbelts is 62.4 ths ha, including 5 % of the young growth (I state class), 80 % of middle-aged forest plantings (II state class), 10 % of maturing plantings (II state class), 5 % of mature and overmature plantings (III state class). Living ground cover is formed by the following species: Koeleria pyramidata L., Poa pratensis L., Festuca pratensis H., Elytrígia repens L., Dactylis glomerata L., and Phlum pratense L. Aboveground phytomass is 100–300 g/m2; height is 25–32 cm. Plantings are characterized by the quality classes: young growth – I and II; middle-aged and maturing – III; mature and overmature – IV. At the age of natural maturity (70 years), the Robinia trunk reaches the average height of 15.1 m with the average diameter of 22.1 cm. The total stock of wood reaches 18, (ths m3), including (ths m3): young growth – 68 (ths m3); middleaged plantings – 14,871 (ths m3); maturing plantings – 2,187 (ths m3); mature and overmature plantings – 1,314 (ths m3). Aboveground phytomass in young growth is 20.2 t/ha; in mature and overmature plantings it is 391.2 t/ha. In the region it is estimated at 17,070 ths t, including (ths t): young growth – 64; middle-aged plantings – 13,753; maturing plantings – 2,032; mature and overmature plantings – 1,221. The share of stem mass reaches 84.5–80.8 %; woody greenery – 4.2–1.5 %; branches – 11.3–17.7 %. Recalculation coefficients of the stock into aboveground phytomass are the following for: young growth – 0.936; mature and overmature forest shelterbelts – 0.929. Phytosaturation of forest shelterbelts varies within 0.314–2.474 kg/m3. Forest shelterbelts have accumulated 8,534 ths t of carbon, which is estimated at 145.1 mln dollars. The sphere of application of the research results is the Krasnodar Krai forestry, which is recommended to create an additional 60 ths ha of forest shelterbelts, which will provide a normative protective forest cover of arable land of 5 % and annual carbon sequestration up to 3.4 t/ha.

Robinia Pseudoacacia L

Anthropogenic overexploitation poses significant threats to the ecosystems that surround mining sites, which also have tremendous negative impacts on human health and society safety. The technological capacity of the ecological restoration of mine sites is imminent, however, it remains a challenge to sustain the green restorative effects of ecological reconstruction. As a promising and environmentally friendly method, the use of microbial technologies to improve existing ecological restoration strategies have shown to be effective. Nonetheless, research into the mechanisms and influences of rock-solubilizing microbial inoculums on plant growth is negligible and the lack of this knowledge inhibits the broader application of this technology. We compared the effects of rock-solubilizing microbial inoculums on two plant species. The results revealed that rock-solubilizing microbial inoculums significantly increased the number of nodules and the total nodule volume of Robinia pseudoacacia L. but not of Lespedeza bicolor Turcz. The reason of the opposite reactions is possibly because the growth of R. pseudoacacia was significantly correlated with nodule formation, whereas L. bicolor’s growth index was more closely related to soil characteristics and if soil nitrogen content was sufficient to support its growth. Further, we found that soil sucrase activity contributed the most to the height of R. pseudoacacia, and the total volume of root nodules contributed most to its ground diameter and leaf area. Differently, we found a high contribution of total soil carbon to seedling height and ground diameter of L. bicolor, and the soil phosphatase activity contributed the most to the L. bicolor’ s leaf area. Our work suggests that the addition of rock-solubilizing microbial inoculums can enhance the supply capacity of soil nutrients and the ability of plants to take up nutrients for the promotion of plant growth. Altogether, our study provides technical support for the practical application of rock-solubilizing microbes on bare rock in the future.
