Francis Skorina Gomel State University, Sovetskaya str., 104, Gomel, 246019 Republic of Belarus
Keywords: forest use, contemporary status, volume of final felling, forecast, Republic of Belarus

Abstract >>
Contemporary status of forest use in the Republic of Belarus is discussed. The analysis of illegal logging in recent decades has been done. Final felling projections to 2030–2040 years is shown. The main problems arising from the establishment of a permanent environmental forest use in the Republic of Belarus have been encountered, and the ways to solve them are shown.

Keywords: woodland, South Baikal region, forest type, type of mixing, representativeness, indicators and criteria

Abstract >>
The definition of woodland is discussed. The structure and dynamics of forestland are considered on the example of the Tankhoisky forestry district in the South Baikal region. In particular, we consider the representation in the woodland series of forest types, forest inventory compartments by series of forest types, the types of tree species' mixing in the birch forest types. The distribution of all forest types by the productivity classes is done. The age dynamics of tree species' composition and tree stand timber stock is considered for the most representative forest types. The characteristics of natural regeneration in this woodland is presented. The features of forest management and forestry regime for the first group of mountain forests in the Baikal lake basin are discussed. In conclusion the geographical and forest inventory features, criteria and materials describing the forest are enumerated.

Pyrogenic Impact on Gray Humus Soils of Pine Forests in the Central Ecological Zone of the Baikal Lake Natural Territory

V. N. Sukachev Institute of Forest, Russian Academy of Sciences, Siberian Branch, Academgorodok, 50/28, Krasnoyarsk, 660036 Russian Federation
Keywords: central ecological zone of the Baikal natural territory, pine forests, ground fires, soil morphology, stock and fractional composition of litter, organogenic pyrogenic soil horizons, ash elements, physical and chemical properties of soils

Abstract >>
The data of experimental research on the dynamics of post pirogenic gray humus soils of pine forests in the central ecological zone of the Baikal natural territory are analysed. Ground litter-humus fires transforms type diagnostic surface organic soil horizons, lead to the formation of new organogenic pyrogenic horizons (Opir). Negative impact of surface fires of varying intensity on stock change, quality of fractional composition of soil organic horizons, and their chemical composition is shown.

General Combination Ability of Common Pine (Pinus Sylvestris L.) n Seminal Gardens

Natural Sciences Institute of the Perm State National Research University, Genkelya str., 4, Perm, 614990 Russian Federation
Keywords: , , , , free pollination, posterity, selection of seed source trees, testing

Abstract >>
Procedure of selection is described on general combination ability (GCA) in the tests of posterity 910 trees. 1425 variants and 41.7 thousand descendants were tested to age 3–18. Tests were completed for four harvests of seed in six tests in the different environments. Tests had the stages and in every next harvest the variants minimized gradually. GCA was expected on combinations from any two harvests (GCA2) and on all four harvests of seed (GCA4). The coefficients of correlation of GCA2 with GCA4 on the average were high (0.74±0.03). At such level of connections, before taking the third crop it is possible to conduct the selection of source trees and to reduce their number and the number of test plantings by half if GCA2 at a tree will appear on the average no less than 108 %. During such selection there will be some losses of source trees with high future (about 10 %). A maximal value GCA4 at too gardens was 119 and 122 %.

Bioindicative Parameters of Stand Growth Stability in the Disturbed Landscapes of Krasnoyarsk and Achinsk Forest-Steppe Regions

V. N. Sukachev Institute of Forest, Russian Academy of Sciences, Siberian Branch, Academgorodok, 50/28, Krasnoyarsk, 660036 Russian Federation
Keywords: Betula pendula, Populus balsamifera, Pinus sylvestris, fluctuating asymmetry index, stand growth stability, morphological and anatomical characteristics, technogenic loadings

Abstract >>
Estimation of growth stability of Betula pendula and Populus balsamifera stands in anthropogenic landscapes in Krasnoyarsk and Achinsk forest-steppe regions was carried out by the values of fluctuating asymmetry (FA). Well-formed dependence of asymmetry increasing in leaves and needles of studied species in natural stands based on the value of technogenic loads and the distance from pollution sources was established. Indices of needle asymmetry at organismic and tissue levels were obtained for Pinus sylvestris from the zone of intensive technogenic loadings in Krasnoyarsk forest-steppe region for the first time. Rating scale of growth stability deviations was designed for pine stands in disturbed regions of Krasnoyarsk forest–steppe.

Keywords: tree stand fragmentation, red squirrel, feeding, edge effect

Abstract >>
The network of edge ecosystems is organized due to the fragmentation of tree stands. It is characterized by high biodiversity and by the presence of available food base for small mammals. The red squirrel is an important furs trade resource. It is attracted to the forest edges, and its intensive food-obtaining activity under the border conditions must be taken into consideration.

Keywords: Siberian stone pine (Pinus sibirica), Korean stone pine (Pinus koraiensis), plantation, variability, seed production, Siberia

Abstract >>
The growth and seed production of Siberian and Korean stone pines at the age of 24–41 years in the «Izvestkovaya» plantation, located in the area of educational and experimental forest enterprise of the Siberian State Technological University (socalled Green Zone of Krasnoyarsk City) were analyzed. It has been found that Korean stone pine (Pinus koraiensis Siebold & Zucc.) is behind of Siberian stone pine (Pinus sibirica Du Tour) in growth rate, the formation of cones and microstrobiles. Inter-and intraspecific variation in the formation of tree crown, cones and seeds size were significant, which allowed selection of individual trees with better reproduction characteristics.

Keywords: forest polygons, forestry contour interpretation, hydrological network, DEM, GIS software

Abstract >>
Polygon layers obtained on the basis of the DEM, may have specific characteristics, such as the emergence of geographically disparate polygons with the same identification number. The paper discusses the experience of spatial analysis such polygon layers, namely the experience of forest parcels adjacent to the parts of a hydrological network, using Arc Map 9.3.1. GIS software.

Abstract >>
The peculiarities of formation of seed productive Siberian stone pine stands near settlements, due to the total destruction of the living ground cover and forest litter, providing heat influx in the root–inhabited zone of the Siberian stone pine trees is discussed in the paper.
