“…In Kazakhstan, large steppe areas burn every year (e.g. 7.6 million ha in 2005, 9.9 mha in 2006 and 2.8 mha in 2007 across W Kazakhstan, Aktyubinsk and Karaganda provinces combined, Arkhipkin and Sagatdinova 2008). Increasing temperatures could lead to an increasing steppe fire risk in the future (Tchebakova et al 2009), especially in areas that are currently not grazed and where large biomass stocks built up.…”

Temperate grasslands have suffered disproportionally from conversion to cropland, degradation and fragmentation. A large proportion of the world's remaining near-natural grassland is situated in Kazakhstan. We aimed to assess current and emerging threats to steppe and semi-desert biodiversity in Kazakhstan and evaluate conservation research priorities. We conducted a horizon-scanning exercise among conservationists from academia and practice. We first compiled a list of 45 potential threats.These were then ranked by the survey participants according to their perceived severity, the need for research on them, and their novelty.The highest-ranked threats were related to changes in land use (leading to habitat loss and deterioration), direct persecution of wildlife, and rapid infrastructure development due to economic and population growth. Research needs were identified largely in the same areas, and the mean scores of threat severity and research need were highly correlated. Novel threats comprised habitat loss by photovoltaic and wind power stations, climate change and changes in agriculture such as the introduction of biofuels. However, novelty was not correlated with threat severity or research priority, suggesting that the most severe threats are the established ones.Important goals towards more effective steppe and semi-desert conservation in Kazakhstan include more cross-sector collaboration (e.g. by involving stakeholders in conservation and agriculture), greater allocation of funds to under-staffed areas (e.g. protected area management), better representativeness and complementarity in the protected area system and enhanced data collection for wildlife monitoring and threat assessments (including the use of citizen-science databases).

“…into the system. In the development of the system various methods and technologies of processing optical and radar remote sensing data were introduced (Arkhipkin and Sagatdinova, 2008), (Arkhipkin et al, 2007), (Arkhipkin et al, 2010) and (Spivak et al, 2004). At the current time, the system is a three-level structure whose levels are determined by the spatial resolution of the used Remote sensing data.…”

<p><strong>Abstract.</strong> The article gives a brief description of the system of space monitoring of high water and floods. Its main tasks are the operational dynamics of snow and ice cover melting and the passage of flood waters. The solution of these tasks is carried out in three levels corresponding to the low, medium and high resolution of remote sensing data. An important role in monitoring is given to radar data. This is due to the features of the radar survey: independence from weather conditions and time of day, regularity, good spatial resolution, the possibility of using polarimetric properties (including phase information). The use of radar data also provides additional information, including the allocation of wet soils, flooded vegetation and infrastructure. The presence of large time periods of repeated survey, interference (cloudiness, haze, noise, etc.), different spatial resolution necessitates a complex analysis of optical and radar data in flood space monitoring. Such analysis makes it possible to better observe the flood dynamics, more precisely identify of flooding zones and determine their structure. Features of radar survey (transparency of dry snow and change of reflected signal during snowmelt) allow using them to determine the beginning of snow melt and determine the degree of water content in it. Optical data are also used to determine the area and structure of the snow cover. Method of detecting the beginning of the snowmelt period consists in the comparison of the current radar image with a base image created as an average image from the winter images with dry snow.</p>

“…Earlier cattle ruined ephemeral cover up to 30-35% of projective cover and if the small cattle dominated in the gazing, the herbage was extracted with their hooves [2][3][4][5]. Thin ephemeral herbage did not allow desert and desert-steppe fires to procced, which became more frequent last time as all over Kazakhstan [2,[6][7][8] and Russia [9][10][11][12][13].…”

Carex is the most species-rich genus in the family of Cyperaceae. Carex with Phragmites australis or Bolboschoenus maritimus dominates in the building the plant cover of wet habitats. Value of mossy Carex as forage is too low, even in the hay [1]. Forage plants, as bottle sedge (Carex physodes, Carex subphysodes) growing on sand and sandy soil and Carex pachystylis growing on loamy grey soil, are distinguished by its high content in protein and being valuable forage plants [1].
