Title: Effects of livestock exclusion on forest trees regeneration (Case study: Ramsar's district 1- Iran)
Abstract: In order to study the effect of livestock removal on forest regeneration in Ramsar district 1- Mazandaran Province, the compartment 23 with area of 96 ha was selected. The required data were collected for two separate years (2000 and 2009) and compared together. To assess the regeneration abundance, analysis were carried out in both years using systematic random sampling with network dimensions of 150×200 m and sample plot of 100 m2. Within each sample plot, regeneration conditions were categorized in 4 classes: seedling with height less than 1.30 m, diameter at breast height 0-2.5, 2.5-7.5 and 7.5-12.5 cm. Results showed that the regeneration of tree species belonged to Fagus orientalis, Carpinus betulus, Acer spp, Alnus spp, Tilia begonifolia, Ulmus glabra and Cerasus avium. The comparison of the obtained results in two years (2000 and 2009) showed that the mean regeneration of all tree species increased in 2009 as it was reflected in all 4 diametric classes. There was a statistically significant difference between the means of tree regeneration abundance in 2000 and 2009 (p<0.01, df = 8, χ2 = 748.661). Based on obtained results, the removal of livestock from the forest led to a significant increase in the regeneration establishment in a period of 9 years. The increase was more than 110% in 2009. It concluded that removal of livestock from the forest and the forest conservation plans are essential in regeneration establishment within the study area.

Title: Beech bark necrotic disease (Fagus sylvatica L.) of tracheomycotic type in Central and South-eastern Europe
Abstract: The authors present results of long term monitoring of beech stems bark necrotic disease of maternal stand in Czech Republic, Slovakia, Poland, Hungary, Romania, Serbia and Bulgaria. Overall, 10,863 beech trees were evaluated at 121 localities. The most trees (6679) were evaluated at 55 localities in Slovakia and 2684 trees at 50 localities in Bulgaria. In each country, we noted a wide interval of values of the beech stems necrotization index (ISN) - e.g. in Bulgaria, from 0.22 to 1.50 and in Slovakia from 0.53 to 1.97. The average value ISN in Slovakia (1.22) was out of all countries surpassed only by a value ISN found out in Czech Republic (1.35). Overall, in Bulgaria, we registered more favourable state of beech bark necrotic disease than in Slovakia. As much as 80% of Bulgarian localities had values ISN < 1.1 compared to only 49.1% of Slovakian localities. At the same time, 12.7% of Slovakian localities had values ISN > 1.5, whilst there was no Bulgarian locality recorded in this interval. We consider Slovakia and Bulgaria the countries where the issue of the beech bark necrotic disease of tracheomycotic type is relatively well processed.

Title: Review of historical outbreaks of the nun moth with respect to host tree species
Abstract: The nun moth (Lymantria monacha /L./) is a polyphagous pest feeding on coniferous and deciduous trees in Eurasia. This paper, based on a literature review, presents an overview of the nun moth outbreaks in Czech forests from 1784 to 2010 in terms of host tree species. At least 22 genera of host trees, bushes and herbs were recorded in the Czech Republic. On the other hand 2 genera were evaluated like non-hosts and 4 genera like indifferent. The nun moth defoliated mainly coniferous forests (almost 90 % of all recorded outbreaks with known data about host trees) in the Czech Republic. Forests with mixture of coniferous and deciduous trees were defoliated nine times less frequent, and only insignificant portion were recorded in clearly deciduous forests. Although wide host range, the nun moth has defoliated predominantly spruce forests (almost 70 %). Mixed coniferous (with mixture of spruce, pine, larch, fir) forests were attacked three times less frequently then the spruce forests. Pine and larch forests were defoliated in low range. Defoliations were sorted also according the intensity. Spatial distribution of the recorded outbreaks was displayed in maps.

Title: The effect of coppice management on the structure, tree growth and soil nutrients in temperate Turkey
Abstract: Coppicing was widespread throughout Europe for many centuries but was largely abandoned in the second half of the 19th century. Currently, there has been a renewed interest in coppicing for biomass production and nature conservation. We studied differences in soil chemistry and tree growth between active and abandoned coppices to highlight the impacts of coppice restoration on soil fertility and tree. Stand structure, collected soil samples and tree cores were compared on 46 research plots in temperate Turkey. The plots were set as actively managed and abandoned coppice stand.  In our study no effect of coppicing on growth rate was confirmed.  Active coppice stands had lower content of Ca, K, N and C:N and higher soil acidification than abandoned coppices. The tree growth rate was significantly higher on more nutrient rich soils. Coppice restoration may not result in increased biomass production in long term periods due to negative effect on soil fertility.

Title: Effects of light exposure in freezing temperatures on winter damage to foliage of Norway spruce container seedlings in mid and late winter: Pilot experiments in an open field
Abstract: Norway spruce (Picea abies (L.) Karst.) is widely planted for reforestation in the boreal zone. It is sensitive to frost and high irradiance during the growing season, and also to winter damage, which cause growth losses in reforestation. This study made a pilot attempt to examine the needle damage and seedling vigour on hardened Norway spruce seedlings under freezing temperatures using natural and artificial light exposure from a day to weeks in an open field in mid and late winter in central Finland. The treatments induced needle browning and decreased seedling vigour, which reduced shoot and root growth during the following growing season. Visibly damaged, mottled needles of one-year terminal shoots had practically no healthy-looking cells. The new buds, however, were healthy and were able to grow during the following season. Our results suggests that, above the snow cover, the freezing temperatures and wind, rather than the intensity of light radiation, induced the observed needle damage found immediately after the treatments, and the subsequent growth reduction in the following growing season. The preliminary methods used outdoors could not distinguish all the different environmental conditions and their mechanisms of effects on seedlings, which demonstrates the need for further method development in controlling experimental conditions of air temperature, radiation intensity, and air current in future research of seedling winter damage outdoors.
