The results of the study of protective forest plantations state in the Eastern Kama region of the Republic of Tatarstan are presented. The assessment of the study area landscape, the soil conditions for the formation of protective forests is given. Under the canopy of forest phytocoenoses, brown-brown forest, gray forest soils and rendzins are identified. Pine, spruce, birch, and poplar protective plantations, pure and mixed in composition, were studied. On the trial plots the taxation indicators of stands are determined.

Abstract. To assess contribution of multiple environmental factors to carbon exchanges between the atmosphere and forest soils, four old-growth forests referred to as boreal coniferous forest, temperate needle-broadleaved mixed forest, subtropical evergreen broadleaved forest and tropical monsoon rain forest were selected along eastern China. In each old-growth forest, soil CO2 and CH4 fluxes were measured from 2003 to 2005 applying the static opaque chamber and gas chromatography technique. Soil temperature and moisture at the 10 cm depth were simultaneously measured with the greenhouse gas m

Abstract:

There has been a massive drying out of spruce plantations in recent years. Many versions about the cause of this phenomenon have been put forward by scientists. Despite the active study of the problem of drying out of spruce plantations around the world, a forest management system aimed at reducing the damage from drying out has not been developed yet. Important silvicultural indicators of plantations that can affect their stability are the type of forest growing conditions and the type of forest. The purpose of the study was to establish the influence of the type of forest and the type of for

Introduction. Slope lands are less resistant to external influences and more prone to degradation. Their agricultural use is possible only with the creation of complex agro forest ameliorative protection, the basis of which are forest belts. In hard climatic conditions, old - growth forest belts (even with changes in their composition and preservation) contribute to the improvement of microclimatic conditions on the entire slope. The aim of the research was to study the condition of old - growth protective forest belts placed on soils of limited forest suitability and their impact on the susta

Abstract:

In this study a new method of locating culverts is presented with the composition of achieved discharge from hydrological analysis and simulated forest roads in RoadEng 3D simulator to improve drainage condition. Locating culverts was performed on a small scale (1:20 000, using GIS) and large scale (1:2 000, road geometric design simulator). The small-scale study regarding the achieved discharge from streams shows that the installation of some culverts is not necessary. The large-scale study also showed that the geometric design of forest road has a significant effect on locating culverts and

Abstract:

In 1986 the Ontario government established a long-term program to monitor hardwood forest health. The program was initiated in response to widespread reports of forest decline in North America and Europe and the implication that air pollution, specifically acidic deposition, was a causal factor. Visual symptoms of branch dieback, leaf colour, and leaf size, have been quantitatively evaluated on about 15 000 trees in 110 plots. This report summarizes the results of the first 12 years (1986 to 1998). Over that time period, relative to the 1986 baseline year, 84% of the plots have improved in con

Along with this, there are various problems, such as loss of soil fertility, increased erosion, groundwater pollution and environmental pollution in general. Therefore, there is a need for constant monitoring of agroecological indicators of the soil in the conditions of intensive agriculture

Abstract:The variation in CO2 flux from the forest floor is important in understanding the role of mangrove forests as a carbon sink. To clarify the effects of soil temperature and tidal conditions on variation in CO2 flux, sediment–atmosphere CO2 fluxes were measured between June 2012 and May 2013. We used the closed chamber method for two plots, with a 0.5 m difference in elevation (B, high elevation; R-B, low elevation), in a mangrove forest in south-western Japan. CO2 fluxes were highest in the warm season and showed a weak positive correlation with soil temperature in both forests. Estima
