    Wystepowanie pozarow lasu w Syberii Srodkowej w zalesznosci od geograficznej i ocena uszkodzenia lasow
= Geographic conditionality of wildfires and estimition of damages of forests of Central Siberia : материалы временных коллективов / E. I. Ponomarev // Lesne Prace Badawcze (Forest Research Papers). - Vol. 69, № 2. - С. 109-115

Аннотация: This database of forest wildfires that occurred in Central Siberia in the years 2006 and 2007 was created on the basis of satellite image analysis. The database allowed to construct an up-to-date map of fire hazards and depict the geographic distribution of forest and non-forest fires during fire season. The duration of the active burning phase for the majority (88%) of forests in the region was 1 day. The spatial-temporal distribution of forest fires indicates a maximum fire risk at the end of June and the begining of July and in southern regions - also in spring and autumn. The analysis of images with depicting damage to forestland allows to state that c.30-40% are the stands with different stands with different degree of damage of which less than c. 30% show weak signs of recovery.

Аннотация: The Siberian moth is the main ecological factor that initiates succession in the dark coniferous forest in taiga subzone of Southern Siberia. Subsequent wildfires only further modify the process of reforestation in "shelkopryadniks". A review of investignations of the Siberian moth outbreak of 1989-1997 demonstrates different ecological and economic consequences of the global ecological phenomenon.

    Forest fuel smoke producing capability
: материалы временных коллективов / A. V. Bryukhanov, P. A. Osavelyuk, E. V. Guliaeva // Boreal forests in a changing world: challenges and needs for action: Proceedings of the International conference August 15-21 2011, Krasnoyarsk, Russia. - Krasnoyarsk : V.N. Sukachev Institute of forest SB RAS, 2011. - С. 115-117. - Библиогр. в конце ст.

Аннотация: The total environmental damage induced by pollution by smoke from wildfires is difficult to evaluate even roughly. This is partly due to insufficient data on smoke pollution, which is in turn attributed to unsufficient or even lacking estimated data composition and amounts of emissions from wildfires. Laboratory analysis of smoke producing capability (SPC), or smoke production coefficient would enable to make compilation of a comprehensive database of negative impacts smoke emission of wildfire. Our study showed that for boreal Siberian species the greatest SPC produced birch bark (Betula).

Sukachev Institute of forest SB RAS, 2011. - С. 123. - Библиогр. в конце ст.

Аннотация: The increasing of burning area in Siberia, the extension of fire season and fires intensity lead to significant carbon emission. One of the important tasks is to describe the spread of smoke aerosol and other combustion products using actual meteorological data and fire state information. A smoke aerosol covers territory hundreds times larger than the burning area and has an effect on forming the cloud and sediment formation exactly above the fire zone.

Аннотация: A fire history of northern larch forests was studied. These larch forests are found near the northern limit of their range at similar to 71 degrees N, where fires are predominantly caused by lightning strikes rather than human activity. Fire-return intervals (FRIs) were calculated based on fire scars and dates of tree natality. Tree natality was used as an approximation of the date of the last fire. The average FRI was found to be 295 +/- 57 years, which is the longest reported for larch-dominated stands. Prior studies reported 80-90-year FRIs at 64 degrees N and similar to 200 years near the latitude of the Arctic Circle. Comparing data from fires that occurred in 1700-1849 (end of the Little Ice Age, LIA) and 1850-1999 (post-LIA warming) indicates approximately twice as many fires occurred during the latter period. This agrees with the hypothesis that observed climatic warming will result in an increase in fire frequency. Our results also indicate that fires that did not leave visible fire scars on the tree stem may be identified based on the date of growth release revealed from dendrochronology.

Аннотация: It is shown that the diagnostics of the stage of woodland soils affected by wildfires and forest cuts can be determined by the evaluation indexes of the range of the scale of abundance of typical ecologic-and-trophic groups of microorganisms (ECTGM), microbiological activity coefficients, reserve and abundance fluctuations, and metabolism. The degree of impact of the technogenic emissions on the forest cover, soil, and phyllosphere according to ECTGM abundance on the diagnostic environments and their fermentative activity is expressed with the help of an advisability functional relation.

Аннотация: Verified estimates of wildfire area and related carbon emissions in territories of Russia are reported for the period of 1998-2010. It is shown that the average burnt area is estimated to be at 8.23 million hectares per year (uncertainty +/- 9.0%, confidence interval 0.9), and carbon emissions-121 Tg C yr(-1) (+/- 23%), with a significant interannual variability of these indicators. A quantitative characteristic of fire emissions by species is reported. Forests are a source of three quarters of all carbon emissions caused by wildfires. A significant acceleration of fire regimes is expected during the 21st century as a result of climate change in the country.

Аннотация: The paper focuses on investigating the densities of different ecological trophic groups of soil microorganisms, cellulose decomposition rates, and respiration of cryogenic forest soils in the north of Central Siberia and those of the southern taiga subzone, including those affected by surface wildfires. Psychrotolerant bacteria and micromycetes were found to dominate these soil complexes. The biological activity of the upper soil horizon in the north appeared to be close to that in the south, although the growing season in the former area is shorter compared to the latter.

Аннотация: Problem of wildfires has not been resolved anywhere in the world. Mere increase of technical power does not lead to desirable results. Forests of developed countries burn as actively as those in Africa or in Russia. The main reasons of wildfire problem are as follows: (1) Constant wandering of dry seasons over the planet causing outbreaks of wildfires. (2) Unpredicted self-development of ordinary wildfires into awful fire disasters. (3) Difficulties in delivery and use of heavy machines on hardly accessible territories. (4) Absence of a perfect technique for economic evaluation of how effectively the wildfire control system works. (5) Absence of the system of payments encouraging wildfire fighters. To solve the problem of wildfires in Russia it is necessary to: (1) Create the Russian wildfire behaviour and fire effects prediction system on the basis of the developed classification of vegetation fuels and methods of their mapping as well as maximum utilization of forest inventory information and Geographic Information System (GIS). (2) Elaborate a technique of proper wildfire monitoring including estimation of vegetation damage. (3) Improve daily rating of regional fire danger. (4) Improve fire-preventive arrangement of the territory covered by vegetation, the main goal being creation of favourable conditions for active fire management. (5) Choose the main direction in elaboration of fire-fighting means and methods taking into account their universality, simplicity, reliability, etc. (6) Elaborate an improved technique for estimation of economic effectiveness of the wildfire control system. (7) Develop international cooperation of scientists and professionals in fire management.

    Influences of boreal fire emissions on Northern Hemisphere atmospheric carbon and carbon monoxide
[Text] / E. S. Kasischke [et al.] // Glob. Biogeochem. Cycle. - 2005. - Vol. 19, Is. 1. - Ст. GB1012, DOI 10.1029/2004GB002300. - Cited References: 80 . - 16. - ISSN 0886-6236

Аннотация: 1] There were large interannual variations in burned area in the boreal region ( ranging between 3.0 and 23.6 x 10 6 ha yr(-1)) for the period of 1992 and 1995-2003 which resulted in corresponding variations in total carbon and carbon monoxide emissions. We estimated a range of carbon emissions based on different assumptions on the depth of burning because of uncertainties associated with the burning of surface-layer organic matter commonly found in boreal forest and peatlands, and average total carbon emissions were 106-209 Tg yr(-1) and CO emissions were 330-77 Tg CO yr(-1). Burning of ground-layer organic matter contributed between 46 and 72% of all emissions in a given year. CO residuals calculated from surface mixing ratios in the high Northern Hemisphere ( HNH) region were correlated to seasonal boreal fire emissions in 8 out of 10 years. On an interannual basis, variations in area burned explained 49% of the variations in HNH CO, while variations in boreal fire emissions explained 85%, supporting the hypotheses that variations in fuels and fire severity are important in estimating emissions. Average annual HNH CO increased by an average of 7.1 ppb yr(-1) between 2000 and 2003 during a period when boreal fire emissions were 26 to 68 Tg CO(-1) higher than during the early to mid-1990s, indicating that recent increases in boreal fires are influencing atmospheric CO in the Northern Hemisphere.

    Disturbance recognition in the boreal forest using radar and Landsat-7
[Text] / K. J. Ranson [et al.] // Can. J. Remote Sens. - 2003. - Vol. 29, Is. 2. - P271-285. - Cited References: 32 . - 15. - ISSN 0703-8992

Аннотация: As part of a Siberian mapping project supported by the National Aeronautics and Space Administration (NASA), this study evaluated the capabilities of radars flown on the European Remote Sensing Satellite (ERS), Japanese Earth Resources Satellite (JERS), and Radarsat spacecraft and an optical sensor enhanced thematic mapper plus (ETM+) on-board Landsat-7 to detect fire scars, logging, and insect damage in the boreal forest. Using images from each sensor individually and combined, an assessment of the utility of using these sensors was developed. Transformed divergence analysis revealed that Landsat ETM+ images were the single best data type for this purpose. However, the combined use of the three radar and optical sensors did improve the results of discriminating these disturbances.

Аннотация: This paper study considers the effects of oil exploration and development in the oilfields of Evenkiya, Central Siberia (60degrees30'N/96degrees30'E). The drilling in this area was initiated in 1970, and the first oil was extracted in 1977. Image data from the US' Landsat - 7, the Russian "Resours", and the European ERS-2 remote sensing satellites were analyzed. The information value of the Landsat-7channels was evaluated. In particular, the fresh oil drilling sites effectively differ from old ones in the third (0.63-0.69 mum) and fourth (0.75-0.90 mum) channels. Recently burned areas are detectable in the middle IR (1.55-1.75, 2.08-2.35 mum). The classification accuracy depends on the number of channels used, but does not improve greatly using more than 4 or 5 channels. Landsat - 7 scenes enable the detection of patterns for parallel strips (5 - 10 in in width) of cut forest, the first sign of the oil reconnaissance. Alongside the direct impacts of oil-exploitation, fire frequency was increased. The "big" fires (area > 200 ha) caused similar to90% of the total damage, but only accounted for 10% of total firescars. The area of human-caused impact is similar to20% of territory, which is similar to2.5 higher than average for known oil development areas within the Landsat scene. The ERS-2 scenes were found to be effective for mapping fresh drilling sites only. The comparative analysis of "Resours" KFA-1000 camera scene (June 1984) and Landsat-7 (October 1999) showed that during this period the number of oilrigs increased nearly 5 times. Generally, the Landsat-7 data are effective for early detection of the anthropogenic impact on the Siberian larch-dominated communities.

Аннотация: The burned area, fuel type, crown fire percentage, and carbon release of the southern Siberia 2003 wildfire were analysed using AVHRR, MODIS, MERIS, ASTER images and a carbon release model. More than 200 000 km2 were burned from 14 March to 8 August 2003, of which 71.4% was forest, 9.5% humid grassland, and 2.15% bogs or marshes. During 1996 to 2003, 32.2% of the forested area and 23.36% of the total area was burned, and 13.9% of the total area was affected by fire at least twice. Direct carbon emission from this 2003 fire was around 400640 Tg. The 2003 Siberian fires could well have contributed to the high increase of the atmospheric CO2 and CO concentration in 2003. The increasing human pressure coupled with intensive fire severity, recurrent fire frequency, and increasing occurrence of summer droughts will reduce the carbon sequestration potential of this important carbon pool.
