Both regions are very remote, sparsely populated and hard-to-reach, but it is exactly these forests that are the most vulnerable to careless foresting practices.
The Krasnoyarsk region stretches from north to south more than 3,400 kilometres and from west to east from 450 to 1,500 kilometres. Such distances exclude climate monotony. In the Minusinsk Basin summer lasts five months of the year, in the north of Taimyr – the summer is only two months long. The Krasnoyarsk region climate is harsh and very continental. This difference can be seen between winter and summer months between day and night temperatures. In the hottest month of the year, for one and a half week temperature may reach 35 °C during the day, but each morning it could be as low as 17 °C. Loss of heat by the soil in the summer months, especially on clear days and nights, is very large.
The Irkutsk region’s weather is very much the same as in Krasnoyarsk, however the more mountainous regions of the Irkutsk region feature greater variation in temperatures and in that respect can be rightfully defined as having harsher micro-climates. The Irkutsk region itself has a sharply continental climate. The average cold season temperature range from -12 °C to -20 °C, and the warm from 16 °C to 20 °C. The region’s area is 774 846 km².
To begin with we would like to stress out that we have two main species of trees that we source from Siberia, these are:
Siberian Larch and Siberian Cedar.
Albeit both species in the centre of Central Siberia grow together, our company sources cedar forests and larch forests separate from each other. This is done for various environmental and forest management techniques’ reasons. Although the overall approach to logging sites for these two species is the same, the taking care of cutting areas as well as of the demands of each species differ rather much.
Our Siberian Cedar and Siberian Larch originate from a truly majestic area where the river Angara takes its origins. Curiously Siberian Cedar is also known as Angara Pine. The Angara is a river in the East Siberia, 1779 km long and is the largest right tributary of the Yenisei River, the only river flowing out of Lake Baikal. It flows through the territory of the Irkutsk region and the Krasnoyarsk region.
The forests sourced by Aurelius Trading surround the city of Bratsk. It is not just one forest, we source numerous logging sites that spread across different landscapes of the area. We sincerely hope that our reader has already acquainted himself with our article about Siberian Cedar, but even if not, the story that unfolds is one about taking care of one of the truly majestic trees in the land that is home to many myths and magic.
The methods of harvesting In Siberia are slightly different in nature then the the ones used in Western Russia. The forest area is natural and vast, with the population density being low, and infrastructure availability being rather scarce.
This entails that individual companies having often to take their own initiative and responsibility to enhance water protection and sanitary-hygienic standards in their forest properties. When carrying out these works we combine the interests of forest exploitation with forest management objectives, primarily to ensure the resumption of the forest clearings, conservation and enhancement of its environment-forming role. The cutting approaches are tailored to a type of a forest and are categorized in three groups, or systems, for cutting methods: clear-cutting, selective cutting, gradual felling. Each group includes cutting methods, similar in organizational, technical characteristics and peculiarities of their impact on forest regeneration and the conservation of the forest environment.
Given that we have numerous and various territories with a rather rich difference in landscape and environmental requirements, we have to take into consideration and implement any and all of the logging methods.
The good point to start is that the forests are differentiated in accordance with their purpose. When choosing a method for cutting, other than forest exploitation and business interest, we investigate and then take into account the intended purpose of each forest, forestry; properties of tree species in general and properties of tree species in given ecosystem, as is the case with Siberian Cedar growing in Altai Mountains; and of course of the direction forest renewal processes, growing conditions, age structure of forest stands, soil erosion control, etc.
Group I forests are categorized by the application of the following reforestation cutting techniques: voluntary-selective, gradual, continuous, stripped-coupe (wide cutting area up to 100 m.).
In forests of Group II – we implement either solid stripped-coupe, gradual and/or selective cutting technique of higher intensity.
In the forests of Group III we use concentrated clear cutting techniques (solid-logging), as well as, especially in uneven woods, gradual and selective logging in different variants: long, gradual and selective cutting of higher intensity.
Within each group, not all forests alike perform water conservation and protective functions. The main challenge of ensuring that logging in the cutting areas made in the forest of I & II groups, in the mountain forests and special protection areas, that the trees are removed depending on their condition, in some cases, this is carried via voluntary-selective, sometimes clear-cutting by setting the cutting areas up to 50 m.
In selecting the methods for logging and forestry our foresters closely monitor properties of tree species, their attitude at different stages of growth and development to the pace and re-light, windproof, and abundant fruiting periods between seed years.
The methods of logging are different from those employed by our foresters in Western Russia, as this vast region is very different. The curious reader might find out that there are almost no broadleaf species present there, only coniferous. However, these coniferous species grow in stand alone groves as well as growing intermingled together - you can see: fir, spruce, larch cedar and pine covering flat valleys and fighting together for survival in the mountaneous parts of this amazing part of the world.
In general we use three types of logging methods in Siberia: clear-cutting for mixed breed forests in valleys, Group-gradual and Selective logging for hilly and mountaineous regions, and long-gradual cutting for the groves of a single specie. We cover each in detail in the Microclimate and Logging Sites in Siberia
