This article presents a historical analysis of human impact and further step-by-step nature reserve creation within the territory of the current Visimsky State Biosphere Reserve. From the end of XVII to the middle of XX centuries the ecosystem of low-mountain southern taiga forests in the Middle Ural region was strongly exploited by a local mining and metallurgical industry. The establishment of the Visim State Reserve in 1946 did not provide sustainable results but initiated research studies that laid a foundation for a subsequent preservation and the studies of the endemic taiga forests of the Middle Ural in the framework of the modern Visimsky State Biosphere Reserve. Since 1975 the science department of the reserve has conducted regular observations of the nature processes. The reserve has established long-term and efficient collaboration with the Institute of Ecology of Animals and Plants, Ural Branch of the Russian Academy of Sciences. The joint research findings are used in practical solutions of the nature preservation in the region. This collaboration is also focused on the monitoring of the recreational pressure caused by the educational tourism.

Landscape Ecological

Landscape Ecological Structure in the Eastern Part of the North Vidzeme Biosphere Reserve, Latvia Latvia is a country where the forest area has increased and habitat fragmentation has reversed compared with many other European countries. In order to examine the effect of this expansion on biodiversity, vegetation maps dating from 2002 and the years 1930-1936 were used for comparative landscape structure analyses while archive materials from forest plans, and data from the national forest management database were used for land use analysis. Four landscape ecoregions in the eastern side of the North Vidzeme Biosphere Reserve were selected for analysis. Landscape structure indicators derived from landscape ecology were used for the ecological assessment of land use changes. The total number of forest patches had decreased over the study period, but mean patch size had increased for all types of landscape element. This general change was found to vary between different landscape units in the study area. The biggest change in the area of forest patches occurred in the Rūjiena drumlin field, where the amount of forest patches decreased least and forest area increased the most. This study showed that the internal structure of the forest matrix changed substantially. This finding has implications for biodiversity protection if this trend of land use change continues.

The Relationship

The analysis of macromycetes against the background of forest communities is presented in the paper. The relationship between the mycoflora and the exploited habitat - type of phylocoenosis, stand composition, type of substrate, humidity - has been determined referring to ecological groups of fungi. Communities with considerable proportion of fir-tree in stand were particularly taken into consideration.

The Korean DMZ—at once a war zone, a historical landscape and a living laboratory—offers a compelling example of how scientific fieldwork can alter the definition of place. This article explores how scientists introduced new layers of meaning to the region, thereby contributing to shifts in perspective about the border area and to changes in land-use policies there. As early as the mid 1960s, scientists described the DMZ as a scientifically unique and valuable place and argued for setting it aside as a nature reserve; by the late 1990s, the vision of the DMZ as a scientific landscape gained currency both within Korea and internationally and has become central to discussions about the zone's future. This article draws from published and unpublished scientific reports whose authors directly argue for assigning official conservation status to all or part of the DMZ and its border regions; it aims to demonstrate the important role scientists have played in redefining the DMZ through highlighting its environmental and scientific value. The article places these developments within the larger environmental history of Korea, suggesting links between changing emphases in environmental activism and policy-making and evolving ideas about the value and purpose of the DMZ.

Five distinct forest communities were recognized along a 3-km transect. These are, listed in order of decreasing elevation: (i) open black spruce/feathermoss - Cladonia, (ii) closed black spruce/feathermoss, (iii) open black spruce/Sphagnum, (iv) black spruce woodland/Eriophorum, and (v) white spruce/alder/Calamagrostis (restricted to a narrow band adjacent to a stream). Several techniques of ordination were used to recognize these five forest communities plus two intergrades: (open black spruce/feathermoss - Cladonia) - (Sphagnum) and open black spruce/Sphagnum - woodland/Eriophorum.The distribution of two-thirds of the plant species was highly correlated with vegetation–slope zones. Results of the fit of Gaussian curves also suggest that vegetation boundaries were well placed. The distribution of the four soil series in the area was well correlated with vegetation–slope zones: three were limited to one zone each. Permafrost, absent from the soil on the ridgetop and upper slope, was generally within 40 to 50 cm of the surface elsewhere and tended to be at shallower depths as elevation decreased. The most striking differences in forest floor properties were found in the white spruce zone compared with the six black spruce dominated zones. The white spruce forest floor was markedly thinner and had higher levels of nutrients. In the six black spruce dominated zones, forest floor thickness and concentrations of N and Mg tended to increase with distance downslope, and P and K decreased.
