Rare species of plants

The habitats of rare species of plants in the Russian and Mongolian parts of the Baikal basin are visually presented on the map “Rare species of vascular plants” using the cartographic interpretation technique. In order to create this map for the Russian part of the basin, the authors used the lists and characteristics of rare species included in the Red Book of the Russian Federation (Plants and Fungi). In this part of the basin, the map shows the habitats of 31 vascular plants (see the list) with different categories of the extinction risk according to the Red List of Threatened Species of the International Union for the Conservation of Nature. Category 0 (probably extinct, but the possibility of their preservation cannot be excluded) includes Isoetes lacustris. Category 1 (endangered) includes four species: Astragalus olchonensis, Vicia tsydenii, Festuca bargusinensis, and Viola incisa. Category 2 (decreasing in number) also includes four species: Caulinia flexilis, Hedysarum zundukii, Epipogium aphyllum, and Deschampsia turczaninowii. Category 3 (rare) includes 25 species represented by small populations that are currently not endangered and vulnerable. Often, these species are distributed within a limited area or have a narrow ecological amplitude.

For the map of the Mongolian part of the Baikal basin, we used information on the species composition and location of rare species of vascular plants from the electronic version of Mongolian Red Book. Habitats of 51 species are identified including a rare endemic species Saxifraga hirculus, six very rare relics: Adonis mongolica, Vicia tsydenii, Kobresia robusta, Nymphaea tetragona, Lancea tibetica, and Tulipa uniflora, as well as rare relics: Zigadenus sibiricus and Caryopteris mongolica are marked. Altogether, there are 31 very rare and 11 rare species.

The map “Rare species of vascular plants under regional protection” shows the Baikal basin’s habitats of rare species under regional protection in Irkutsk oblast (Red Book of Irkutsk oblast), Buryatia (Red Book of the Republic of Buryatia), and Zabaikalsky krai (Red Book of Chita oblast). Altogether, there are 868 habitats of 201 species of vascular plants listed in the regional Red Books and the Red Book of the Russian Federation. Species in different regions have different status depending on the state of species population. Among the regional species, Lagopsis eriostachya and Isoetes lacustris have Category 0 (probably extinct), while 28 species are endangered (Category 1).

The map “Plant communities requiring protection” uses conventional symbols and is created based on the information from the Green Book of Siberia, Atlas of Irkutsk Oblast, and Electronic Atlas of the Slyudyansky District. According to the Forest Code of the Russian Federation, forests under protection of Group 1 and forests in specially protected territories must be conserved in the Baikal basin because of their economic and social values. These forests serve to protect water resources, preserve the environment, and perform sanitary, hygienic, therapeutic, and other functions. The following communities also require protection due to their scientific importance as standards of indigenous vegetation: the Polygonum bistorta + Carex aterrima and Stemmacantha carthamoides meadows; Rhododendron aureum alpine tundras of the subalpine zone; Filifolium sibiricum, Festuca litvinovii, and Stipa klemenzii - S. Baicalensis - Eremogone capillaries steppes; Ulmus macrocarpa + Spiraea pubescens shrub steppe communities; Betula davurica - Artemisia desertorum + Calamagrostis brachytricha + Carex reventa forest communities; and Carex lasiocarpa + C. pseudocuraica + Iris laevigata marsh communities. Among the protected communities are very rare (Spodiopogon sibiricus; Armeniaca sibirica + Spiraea pubescens), relict (Arundinella anomala + Lespedeza hedysaroides), and unique (Stipa baicalensis + Paeonia lactiflora) communities, as well as communities located on the margins of their habitats (Pinus pumila; Caragana jubata) and reducing their habitat due to a high resource-related importance (Filifolium sibiricum + Phlojodicarpus sibiricus). The maps showing the distribution of rare vascular plant species and plant communities requiring protection can be used in the development of environmental policy aimed at optimizing nature resources management in the Baikal region to protect its biodiversity.

Fuel and energy resources and their development

Fuel and energy resources of the Baikal basin are represented by deposits of solid fossil fuels (black and brown coals of different ranks), oil shales and uranium.

Coal deposits are confined to the Upper-Mesozoic depressions of the Transbaikalian type, the most significant of which are the Tugnuiskaya, Gusinoozerskaya, Udinskaya, Chikoiskaya and others. The main reserves of black coals within the territory under consideration are concentrated in the Erdem-Galgataiskoe, Krasnochikoyskoe, Nikolskoe, Olon-Shibirskoe, and Zashulanskoe deposits, while the reserves of brown coals are localized in the Gusinoozerskoe, Zagustaiskoe, Taseiskoe, Sharyngol, and Ulaan-Ovoo deposits. The largest deposits are located in economically developed regions with an extended infrastructure, including the presence of traffic arteries in the form of railways and auto-roads. Out of 33 coal deposits, located within the territory of the Baikal basin, sixteen are currently under development.

To date the largest coal producer not only in this area, but in the entire East Siberia and the Far East is the Tugnuisky open-pit coal mine, which mines the Olon-Shibirskoe deposit (97% of the reserves occur within the Petrovsk-Zabaikalsky municipal district of Zabaikalsky krai, and 3% are deposited in the Mukhorshibirsky district of the Republic of Buryatia). Due to the introduction of the cutting-egde high-efficiency equipment produced by the world-renowned manufacturers, coal extraction here more than doubled in three years reaching about 13 million tons in 2012.A coal-preparation plant equipped with unique technologies was built in order to increase marketability of the produced coal. Currently, the capacity of this plant has reached nine million tons. Coal is mainly exported to Japan, Korea, China and other APAC countries.

The coal industry of Buryatia experienced a significant decline after closing in the early 1990s of the major coal producers of the time such as the Kholboldzhinsky open-pit mine and the Gusinoozerskaya mine (Selenginsky district). Currently, the OAO (Open Joint Stock Company) “Ugolnaya kompaniya Bain-Zurkhe” holds licenses for the Bain-Zurkhe and Kholboldzhinsky sites of the Gusinoozerskoe deposit. This company has resumed the coal feed from the deposit to the Gusinoozerskaya state district power plant. A radically new development technology – a highwall mining complex is applied. There is a gradual growth in coal production (932 thousand tons in 2012).

Over the recent years, the OOO (Limited Liability Company) “Ugolny razrez” mining the Okino-Klyuchevskoe brown coal deposit in the Bichursky municipal district of the Republic of Buryatia has expanded its production capacities. It is expected to increase the capacity of this enterprise to five million tons per annum and continue the construction of the railway spur to the Khoronkhoy station for coal conveying to the Gusinoozerskaya state district power plant. Besides, in order to provide the thermal energy facilities of the Republic of Buryatia with the locally produced coal, a construction of a large Nikolsky open-pit mine along with a coal-preparation plant on the basis of the balance reserves of the same-name coal deposit is planned. In the Selenginsky municipal district the OOO (Limited Liability Company) ”Buryatugol” currently develops the Zagustaiskoe deposit. It produces more than 200 thousand tons of brown coal per annum.

The remaining coal producers of Zabaikalsky krai and the Republic of Buryatia within the territory of the Baikal basin mine small volumes (10-50 thousand tons per annum), mainly for housing and public utility sector needs. They are the Daban-Gorkhonsky, Khara-Khuzhirsky, Zashulansky, and Burtuisky open-pit mines. An exception is the OOO (Limited Liability Company) “Razrez Tigninsky” developing the Tarbagataisky deposit in the Petrovsk-Zabaikalsky district. In 2012 it produced 260 thousand tons of brown coal significantly exceeding the level of 2010-2011. All coal is extracted by open-cut mining.

Mongolia's oldest coal producer is the “Nalaikha” mine where small scale extraction was launched in 1912. After the reconstruction in the 1950s the capacity of the mine was brought up to 600-800 thousand tons of brown coal per annum. The mine is the economic mainstay of the town of Nalaikh and was originally the only source of fuel for thermal power plants under construction in Ulaanbaatar. After the official mine shutdown due to the impossibility of its safe operation the former professional miners became engaged in artisanal mining on the facility.

The Sharyngol brown coal deposit was discovered by Soviet geologists in the 1930s, but the development of the deposit began only in 1961, after additional exploration. In the 1980s, the open pit capacity reached the maximum values ​​of 2.5 million tons per annum. Currently, the company is privatized; in 2010 the production was about one million tons and open-cut mining is used.

In the Selenge aimak, the Ulaan-Ovoo high-energy brown coal deposit is currently developed. At the moment the Canadian company “Prophessy Coal” holds the development license of this deposit. Coal mining began in 2010.

Small scale coal mining is underway on Zhulchig bulag, Nuurestein am (Khuvsgel aimak), Saikhan ovoo and Ereen (Bulgan aimak) deposits.

Nowadays two small deposits of uranium raw material (Slantsevoe in the Dzhidinsky municipal district and Zhuravlinoe in the Mukhorshibirsky municipal district of the Republic of Buryatia; both deposits belong to the Selenginsky uranium ore region; a preliminary exploration was conducted on the deposits), and two medium ones, namely, Buyanovskoe in the Eravninsky district of Buryatia (Eravninsky uranium ore region; the deposit is on government standby) and Gornoe in the Krasnochikoysky municipal district of Zabaikalsky krai (Chikoysky uranium ore region) are known within the boundaries of the Baikal basin. The latter deposit is prepared for industrial development to produce natural uranium concentrate. It is planned to construct an underground mine and a heap leach pad for processing mined uranium ore.

Besides solid fuel the territory of the Baikal basin, was recognized as promising for the discovery of commercial deposits of raw hydrocarbons, especially natural gas within the Selenginskaya and Ust-Barguzinskaya rift troughs. According to the results of the prospecting and evaluation works carried out in the Ust-Selenginskaya depression in 1955, 1962, and in the 1990s, its prospective hydrocarbon resources were estimated at 364 million tons of oil, and 520 billion m3 of natural gas (C3 category). Prospect assessment works on the Barguzinskaya depression are in progress.

Due to their small scale and low resin content (8-10%) oil shale deposits are of no commercial interest.

The map “Fuel and energy resources and their development” displays deposits of solid fossil fuels (black coal, brown coal and uranium) designated by various symbols. The symbol size is determined by the size of a deposit. Mining companies are also shown using symbols. The symbol size depends on the average production output over the last 3-5 years (for operating enterprises), or on the design capacity (for companies projected or under construction). The following ranking of enterprises was adopted: large ones with the production of over one million tons, medium ones – from 100 thousand tons to one million tons, and small ones – less than 100 thousand tons per annum for coal mining enterprises; the projected uranium mining company “Gornoe” is a small one with the production of less than one thousand tons of uranium per annum. Circled symbols show the underground mining method, while color indicates the operational stage of an enterprise (operating or projected and constructed). Areals depict the Upper-Mesozoic depressions - potential and actual coal-bearing regions and prospective oil and gas areas.

Ecological functions of landscapes

This map represents the groups of landscapes with similar nature protecting (ecological) functions [Polikarpov et al., 1980, p. 184-194]. They are divided into groups depending on these functions: environment-forming function of geospheric and regional significance, environment-regulating, environment-stabilising, and environment-protective.

The landscapes of goletz, tundra and sparse wood perform the main environment-forming “water-production” function. Of special significance is their snow and water collecting function. These landscapes experience large hydrological loads as they transform the water and transfer it to the subsurface flow. To date, the production of pure water is the most important ecological function as pure water is becoming the most valuable product on the planet. The significance of these landscapes increases due to the protection of depth and purity of Lake Baikal waters.

The environment-stabilizing function is characteristic of all mountain-taiga (moss) landscapes of reduced and limited development – from mountain-taiga shrub-moss dark coniferous and larch communities to shrub and moss-shrub dark coniferous and larch-taiga landscapes in the intermountain depression and valleys with yernik and mixed undergrowth. Their moss cover provides certain ecological conditions. These landscapes are more stable and after external pressure they, as a rule, recover fast. Together with goletz and upper-taiga landscapes, they determine the fundamental set of mechanisms of internal and external interactions of landscapes.

South Siberian and Central Asian (Daurian-Mongolian) steppe landscapes are referred to the group with environment-regulating functions. On the whole, they are characterized by insufficient wetness [Geosystems …, 1991; Eco-geographic …, 1996]. Their role in the flow regulation is rather small. However, under conditions of intense water evaporation they have a very important regulating significance: plant components of these landscapes support the existing ecological balance whose changes can cause the disturbance of the moisture regime and, as a result, the landscape structure. This function specifically intensifies under the conditions of anthropogenic pressure. As a result, all steppe landscapes share high soil-protective significance as they fulfil a technogenic barrier function.

“Herb” landscapes perform environment-protective function: mountain-taiga larch landscapes of optimal development, piedmont and larch-taiga landscapes of optimal development in intermountain depressions, piedmont sub-taiga larch, mountain-taiga pinewood, piedmont sub-taiga pinewood landscapes. Insufficient moistening is characteristic of these landscapes, and changes of their vegetative component can cause changes in hydrological regime towards aridity and, as a result, disruption of landscape structure. Their water and soil-protective role increases. They are characterised by high concentration of different economic activity. Therefore, these landscapes are of technogenic barrier significance.
