The dynamics have been studied of the ecological-functional parameters (EFP) of replantozems formed on the dumps of the Borodinskiy open-pit coal mine in the Kansk-Achinsk Coal Basin (55°52′ N, 94°54′ E) that were not involved into agricultural use during the first 30 years. The work was based on the integrated analysis of the agrochemical properti...

Novel species records for some Russian regions were found as a result of field studies of 2016-2020 and survey of herbarium collections. They improved the species distribution in the Northern Eurasia. The novel species records were revealed for Belgorod, Bryansk, Ivanovo, Leningrad, Omsk, Novgorod, Novosibirsk, Tula, Tyumen, and Vladimir Regions, K...
Article
For the first time, using the example of a key object of the peat river valleys of the Kuznetsk Alatau occupied by spruce forests, it is shown, that due to forest-peat fires, swamp waters are clearly differentiated by the content of main ions. Swamp waters objectively form three groups: 1 – waters of the original type of mineral nutrition (fresh, s...

The article highlights the impact of ammunition at military ranges on the natural environment of disposal. The results of complex studies are presented (soil, vegetation, small mammals) for two sites: in the Krasnoyarsk forest-steppe (N. 1), where in 2013 the disposal of projectiles was completed and in Kansk subtaiga (N. 2), where the disposal of...
Article
In the framework of this work, an attempt has been made to assess the nature (uniformity or uniqueness) of the trees’ influence on soils in various climatic conditions. To achieve the goal of the study, a series of reference polygons was selected, where a single tree species – Scots pine (Pinus sylvestris L.) – has been developing in different ecol...

The article contains an information on the locations for nine of rare plant species in the Republic of Khakassia. Utricularia ochroleuca, higher vascular species of hybridogenic origin, is shown for Siberia for the first time. One species from Marchantiophyta - Riccia fluitans - have been found in Khakassia for the first time. The information for n...

The results of the assessment of biological resources in the dumps of the Borodinskiy coal mine are given. The habitats of the same ecological capacity are distinguished according to the developed classification and interpretation of space imagery. The habitats are allocated according to the technology of recultivation (4 options), the tendency of...

Changes in soil microbial processes and phytocenotic parameters were studied in clearings made for power transmission lines in the subtaiga and southern taiga of Central Siberia. In these clearings, secondary meadow communities play the main environmental role. The substitution of meadow vegetation for forest vegetation, the increase in the phytoma...

The lack of systemic (long-term, complex) investigations of anthropogenic formations is currently a common problem. These data are necessary to form the political opinions and to make managerial decisions with a use of developed standards of monitoring, control and planning. Over a long period of time Institute of Forest has been engaging in the co...
