Two new heather (Calluna vulgaris (L.) Hull.) sites, located in Djerdap National park, on plagioclastic gneiss and podsolised dystric brown soil are described in this paper. Heather is the dominant species in the plant community with beech on these sites (Calluno-Fagetum moesiacae Cvj. 2003). This community is floristically poor and edaphically conditioned. Beech (Fagus sylvatica. subsp. moesiaca (Maly) Czeczott) is the only species in the tree layer, while heather dominates in the ground layer. According to the spectrum of areal types, mesic plant species of middleeuropean distribution type are dominant, with a significant share of plants of the xerothermous submediterranean distribution type. According to the biological spectrum, hemicryptophytes dominate in this community with a significant share of chamaephytes, which indicates deteriorated site conditions. According to the moisture requirements, the community is xeromesophillous, acidophillous according to soil reaction, according to the nitrogen content in soil it is highly oligotrophic, according to the light it is semi-tolerant, and according to the warmth requirement the community is mesothermic. The community of beech and heather represents a degradation stage of beech forests.

Ecological and floristic characteristics of the new subassociation of the Balkan beech and Greek maple plant community with hornbeam (Aceri heldreichii-Fagetum subass. carpinetosum betuli) were studied. This subassociation is recorded and described on Mt. Rudnik, where it occurs at the elevations 950- 1,050 m, on moderate to steep inclinations (10-30?), and cold aspects: northern, northwestern and northeastern. Bedrock consists of sandstones and mudstones. The biological spectrum, ecological spectra and spectrum of distribution types of this community were calculated. The community has phanerophyte-hemicryptophyte character, it is mesophilous regarding soil moisture requirements and temperature requirements, it is neutrophilous to soil acidity, according to light requirements it is tolerant to semi-tolerant. The most numerous group of distribution types is Central European, which confirms the mesophilous character of this community.

In order to manage forest ecosystems at a sufficiently high biodiversity level it is necessary to study the ecological, structural and production characteristics of virgin forests. The research was directed towards identifying the characteristics of mixed fir and beech forests (Abieti-Fagetum s. lat.) in the area of the strict reserve of the National Park Biogradska Gora in Montenegro. Basic characteristics of these forests were researched in the process of definition of forest types. In this manner, it is for the first time that a realistic base for typological management of forests and forest ecosystems with similar ecological and structural characteristics was provided for the specific sites.

Quantitative inventory surveys were done on the woody vegetation in permanently marked plots at distance intervals from the Wik-en-Weeg Dam, Kruger National Park, in 1973. The surveys were repeated in 1990 so that changes in the community composition, the density and the canopy cover and the survival of the woody vegetation could be determined in relation to distance from the dam. Relationships with distance from the dam were shown for the relative density ofCombretumapiculatum in all height classes, the relative canopy cover of the second height class of woody plants, the relative canopy cover of C. apiculatum plants, the survival of all height classes of woody plants and the survival of C. apiculatum and Colophospermum mopane plants. It was concluded that the provision of water for game at the Wik-en-Weeg Dam had an impact on the woody vegetation in the vicinity. The relationships of parameters of the two dominant species, Combretum apiculatum and Colophospermum mopane, with distance from the dam were compared. Combretum apiculatum parameters were more sensitive to impact associated with the dam than those of Colophospermum mopane.

We summarized development and dynamics of natural regeneration in mountain spruce forests in areas affected by bark beetle gradation in the Šumava National Park. Detailed measurements of the regeneration were carried out using Field-Map technology (www.fieldmap.com) on ten permanent research plots. Research plots included the forests with decaying tree layer, stands in partial decline and stands with a generally healthy, or only partially damaged tree layer. Differences in rates of regeneration are very significant between the particular types of plots, especially in the youngest age class. Differences are also evident in the seedling height under varying treatments. The highest numbers of recruits (9,880 per ha) were found under intact overstorey canopies, while the fastest height growth occurred on clearcuts. This study also investigated and evaluated artificial regeneration done in the past.

In three investigated stands the highest increment (8.8 m3/ha per year, i.e. 1.5% of the actual stand volume, measured at the end of the control period) was reached by Jawornik I stand in the initial period of the growing up stage, and Tworylczyk stand in the advanced growing up stage (7.4 m3/ha per year, i.e. 1.2% of the actual stand volume). Jawornik II stand, in the optimum stage, the aging phase, had the lowest increment (3.9 m3/ha per year, i.e. 0.7% of the actual stand volume). The process of a natural volume loss was the most intensive in Tworylczyk stand (7.6 m3/ha per year), a little less intensive in Jawornik II stand (7.1 m3/ha per year), and the least intensive in Jawornik I stand (5.8 m3/ ha per year). The analysis of tree loss, recruitment, and increment, and the relations between these processes, can form the basis for a conclusion that stable stands developed in the Carpathian primeval beech forests in the years 1988–1998. Such steady processes can be used for the development of a stable, multifunctional model of the forest managed by the selection system, or the Swiss irregular shelterwood system in the Carpathian beech stands of a similar structure.

Microclimatic Conditions

This paper deals with large-scale mountain forest decline in the Šumava National Park. The changes in biotic and abiotic properties of forest sites follow the tree layer disintegration. Changed microclimatic conditions such as intensity of irradiance, moisture and temperature of the top holorganic layers together with altered development of ground vegetation could strongly affect the values of microbiological respiration activity and the rates of nitrogen mineralization and nitrification. Soil substrates, built of organic mater, located on stony locations, are endangered by introskeletal erosion. This paper compares these features in pairs of research plots, consisting of dead or cut forest and of living stand. According to the results of this study, higher rates of organic matter decomposition, transformed dynamics of nitrogen and other nutrients and possible nutrient leaching from soil solutions were demonstrated in the forest floor under declined spruce stands. The extent and seriousness of these adverse processes for forest soils are strongly site dependent.

Abstract Through this study, “Pedo-climatic risks over Fălticeni city related orchards”, we intend to conduct a study that highlights the way that a number of parameters such as climate and soil, through their evolution, may be considered a risk factor for orchards nearby Fălticeni city. The analysis of potential risk factors was conducted in direct relation with the of dominant species from studied area, which are apple (Malus domestica) and plum (Prunus domestica). From a climatic perspective, there were taken into account two parameters, temperature and rainfall, to see if they can induce a risk status in the studied orchards and as soil factors that were taken as parameters in our analysis are: soil reaction, carbonates of calcium and the ground water level, which are, at the same time, indicators that impose the most common restrictions over the studied plantations.

The Relationship

Abstract Effects of ungulate pressure on the development of young generation of trees is one of the most important issues in ecology and forestry. Ungulate pressure influence on the development of natural regeneration has been also reported from several national parks. Our study on the effects of ungulate browsing on the young generation of trees was conducted on more than 500 sample plots controlled during one growing season. The overall browsing pressure ranged from 7.6% in seedlings to 20.3% in low saplings. The pressure of ungulates on the regeneration of Picea abies, the dominant species in the Tatra National Park, was by and large below 1%. Broadleaved species were browsed more frequently. The relationship between the plot altitudes and browsing intensity was statistically significant for seedlings and low saplings; at the higher altitudes, the browsing pressure was greater. There was also observed a statistically significant relationship between the type of former management and the browsing degree in seedlings; in the areas subjected to “landscape protection”, the intensity of browsing was higher when compared to strictly protected areas. Pressure exerted by ungulates on tree regeneration was very unevenly distributed, i.e. some plots were heavily browsed and many others - not browsed at all. The most affected tree species were Salix caprea and Sorbus aucuparia, although the percentage of browsed individuals rarely exceeded 50%. Other species favored by ungulates was Acer pseudoplatanus; despite the high browsing pressure, this species was present among seedlings and tall saplings, suggesting that it would be able to recruit to the tree layer. Abies alba was browsed less frequently than the deciduous trees; however, among the tall saplings it was the third most browsed species.
