The nature of catastrophic steppe fires in Siberia, which in recent decades have been spread over thousands of hectares each year, leading to economic losses, and losses of lives and livestock, is being considered. The paper follows spring (March-May) steppe and forest-steppe fires using satellite...

The distribution of individuals of the intermediate form of Norway spruce Picea abies (L.) H. Karst., and Siberian spruce P. obovata Ledeb., distinguished according to the metric parameters of the seed scales, was studied in extensive areas of the range from the Ukrainian Transcarpathia in the west ...

An efficient system for the in vitro propagation of the endangered medicinal and winter-hardy ornamental plant, Rhododendron mucronulatum Turcz., through high frequency shoot induction from seedlings and in vitro-derived apical shoots was developed. While testing different zeatin (Z) concentrations ...

Studies of Pinus sylvestris L. forests in the impact (5-10 km) and buffer (11-40 km) technogenic pollution zones in the vicinity of a large industrial centre Usol'e-Sibirskoe of Irkutsk Oblast have been conducted in 2013-2016. Changes of biogeochemical indexes (acid-base balance, accumulation and...

The search for an optimum value to constrain boundary parameters in distribution models can be (and is) laborious and time-consuming. The accuracy of a distribution fit depends on the predetermined values of the boundary parameters. In this study, we applied the extreme value distributions derived...

The objects of the study were forest shelterbelts represented mainly by pure and mixed stands of black poplar Populus nigra L. in the Republics of Khakassia and Tyva. The sites differed according to soil conditions: southern chernozems, ordinary chernozems, sandy spilled soils. The stand structure...

The paper reviews research papers, develops recommendations for forest regulatory documents. Some deficiencies in the current regulatory framework are revealed. Traditionally, the system of normative documents had a hierarchical structure. The upper level contained basic principles and the most...

Increasing urbanization makes people study the environmental and sanative functions of suburban forests. Forest attendance of over two thousand people per day per hectare in a season is facilitated by a dense network of roads and trails in suburban forests near Krasnoyarsk, so that residents can...

This study analyzes the Russian forest biomass-based bioenergy sector. It is shown that presently - although given abundant resources - the share of heat and electricity from biomass is very minor. With the help of two IIASA models (G4 M and BeWhere), future green-field bioenergy plants are...

This paper analyzes a 35-year experiment of growing Siberian larch Larix sibirica Ledeb. crops, planted at 18 variants of density in the southern taiga subzone of the Krasnoyarsk Krai. We discuss the results of regular observations of the tree growth and productivity in relationship with age...
