AbstractThe results are presented for the vertical distribution of the aboveground phytomass in ripe and overripe pine taiga of Northern Ural foothills. The study demonstrates that the distribution of separate phytomass fractions of trees in the vertical profile of the tree layer can be described mathematically. The aboveground phytomass of pine fo...

AbstractThe potential for the assessment of the tree state based on remote-sensing data has been studied. The integral indicators of seasonal dynamics of the vegetation-index (NDVI) were used. The values for in 2003–2017 were compared for control (unharmed) and damaged test plots in the Khamar-Daban zone near the coast of Lake Baikal (Irkutsk oblas...

AbstractThe paper presents a study of characteristics of the formation of the vegetative cover after forest recultivation with the traditional technology (the planting of forest culture without any improvement of the technogenic substrate) on exhausted quarries of construction materials situated within the middle taiga subzone of the northeastern p...

AbstractThe existing methods for the assessment of fire hazard are analyzed. For the forest regions of Siberia, which are known for the highest indicators of fire hazard, data has been assembled on the degree of natural and weather-dependent fire hazard, as well as the hazard from a source of ignition. It is proposed to assess the natural fire haza...

AbstractThis paper examines the effect of planted spruce (Picea obovata Ledeb.) stands on changes in the morphological characteristics, composition, and properties of cryogenic meadow–chernozem soils that formed in a cryoarid climate under meadow–steppe vegetation in the vicinity of the City of Yakutsk, the central part of the Sakha (Yakutia) Repub...

AbstractThe poplar leaf miner Phyllonorycter populifoliella, a well-known pest from the Gracillariidae family, was first recorded in St. Petersburg in the middle of the last century. This species had its first outbreak in 1991–1999, followed by death of a significant part of poplars in the city and suburbs. Despite the prominence of this pest group...

AbstractMotor-vehicle emissions influence some biochemical and morphological parameters that indicate the vital state of trees in urban plantings. Twenty-eight English oak (Quercus robur) trees growing in places that differing in the level of motor emissions (10−30 m from Moscow Ring Road and the Uzkoye Forest Park in Moscow) have been analyzed for...

AbstractThe differences in morphometric features of the canopy-gap structure of the three dominant forest types in the Valuevsky Forest Park were investigated with high-resolution and detailed-resolution remote sensing data. The forest-community groups (deciduous forest with a predominance of lime, deciduous forest with a predominance of birch or a...

AbstractThe results of stationary studies (1965–2017) on the regularities of the dynamics of the spatial structure of old-growth, cedar-pine forests are shown on the example of a natural-growth, cedar-pine sedge–tall herb–fern forest of the late succession stage (Western Sayan, 53°01′ N, 92°59′ E, individual test site area of 1.56 ha). It was found...

Abstract—The study concerns mapping of the actual vegetation cover of the Vengeri River basin (eastern coast of the central Sakhalin) with an area of more than 33 000 ha. A cartographic model has been created with the use of the algorithm of stepwise discriminant analysis based on the original geobotanical data, a digital elevation model, and the s...
