The aim of this study is to select appropriate criteria such as ecology, economy, social and aesthetic for plantation in Isfahan city, Iran. In order to do this research, 19 questionnaires were distributed among the experts at the study area in 2013. Analytical Hierarchy Process (AHP) technique as a multi-criteria decision making was used for evaluation of urban forestry at this research. Expert Choice software was used for analysis. The results showed that the ecological criterion has the highest weight for urban forestry at Isfahan city and the aesthetic criterion has the lowest priority for urban forestry at the study area. According to the judgments...

Utilization of spruce (Picea abies [L.] Karst.) and beech (Fagus sylvatica L.) wood in plywood production using different processing pressuresOriginal Paper

In this research the spruce plywood board and combined spruce-beech plywood board were prepared in laboratory conditions using two levels of processing pressure. The bending properties in perpendicular and longitudinal direction were measured and compressibility and density were specified. Considering the obtained results, there was found an overall increase of the bending properties in spruce plywood manufactured by the higher pressure and a decline of properties perpendicular to the grain in combined spruce-beech plywood board. On the other hand, combined spruce-beech plywood boards produced by the common processing pressure performed better than...

To achieve a fuller understanding of forest ecosystem functioning, it is necessary to know decomposition dynamics. The objective of this study was to quantify litter production, decomposition and mineralization in Nothofagus pumilio forests, in Tierra del Fuego, Argentina, along an altitudinal gradient during a two-year period and relate them to microclimate conditions and soil properties. We did the research along an altitudinal sequence at 210, 330, 460 and 590 m a.s.l., where climate, soil properties and forest structure were characterized. Litterfall decreased with altitude, and it was highly related with leaf and reproductive organ production....

Assessment of genetic variability in autochthonous elm populations using ISSR markersOriginal Paper

:Genetic diversity between 110 individuals from 6 elm populations (Ulmus minor, U. glabra and U. laevis)was determined using ISSR markers. Altogether 73 ISSR markers were evaluated with the average rate of polymorphic bands of 99.1%, which indicates high genetic diversity between the populations/species. The higher genetic diversity was revealed particularly in the population of U. glabra and this result was supported by the analysis of genetic diversity and differentiation of elm populations. Molecular analyses of ISSR markers allowed to assess the extent of genetic variability of native elm populations and characterize...

Anew approach to forestry that increasingly values non-timber forest functions brings new interest and value also to coppice forests. A case study in the Voskop nature reserve located in the Český kras Protected Landscape Area was focused on a comparison of the timber production of individually growing trees and in multistemmed trees resprouting after cutting (stools). We recorded tree ecological characteristics of trees such as existence of stem cavities, whether the tree grows individually or from a stool and whether or not the tree is broken, dead or has a dying crown. In total 2,670 trees were sampled on a 1,875 ha sample plot. The main tree species...

An assessment of soil compaction caused by machinery used in stump and/or logging residue extraction for energy on soils typical of Ireland. We determined unaffected soil conditions and to find the compaction grade after timber harvesting and bundling activities, and to compare those results with stands where timber harvesting was followed by stump extraction for energy. The investigation was carried out in Ireland on three different locations which had a slightly different proportion of stones in their soils. Two of the soils were purely mineral soils, and the third was a mineral soil affected by anthropogenic activities. To ensure comparable results...

Potential of natural regeneration of Quercus robur L. in floodplain forests in the southern part of the Czech RepublicOriginal Paper

The most common way of pedunculate oak regeneration on the floodplain sites in the Czech Republic is artificial regeneration by clear-cutting. However, what is the real potential of natural regeneration of pedunculate oak? In our research object (3,355 ha of floodplain forest in the southern part of the Czech Republic - Zidlochovice region), we inventoried about 8 ha of successful natural regeneration of pedunculate oak with density ranging between 15,000 and 100,000 individuals per ha on the plots after final cut. All harvested oak dominated parent stands showed a lower stock density that ranged between 0.5 and 0.8. In the next analysis of the survival...

Testing of germination of spruce, pine and larch seed after 10 years from collectionShort Communication

:Germination capacity and germination energy are usually the most frequently used quantitative parameters of forest tree seed. With seed ageing both parameters decreased and the rate of the collapse is given by tree species, age of tree and its seed and biotic and abiotic factors. Relatively little attention has been paid to the age of seed. As it was found, the longevity of the main tree species remained relatively high, and spruce (Picea abies [L.] Karsten and pines (Pinus sylvestris L.) from the investigated areas across the Czech Republic maintained minimally one third of germination capacity or germination energy during the 10...
