We give a critical overview of the management of high-lying beech forests in Bulgaria for two periods during the 20th century. The work is part of a Bulgarian-Swiss joint project entitled«Sustainable and nature-friendly forest management». We address questions of timber use from the point of view of a modern concept for a sustainable and diversified management of beech forests. The most important conclusions of the work are the necessity of completing forestry laws, the liberalisation of the silvicultural systems used in beech forests, and in raising public awareness of forest activities in order to justify their value and diverse effects, especially of beech forests.

In this study the influence of forest management on the characteristics of snags and tree cavities in the Hyrcanian forests of Iran was investigated. In particular, the effect of two sylvicultural treatments (shelter wood and single-tree selection) was assessed in comparison to protected stands. The abundance, diameter, height, and degree of decay of snag species, and the characteristics of birds excavated and natural cavities (number and height from the ground level) were measured by systematic plots in each stand. The results showed that the abundance, species diversity, and size of snags in both of the sylvicultural treatments were significantly lower than the protected stands. The number of birds excavated and natural cavities on thicker snags with moderate decay was significantly higher than other decay classes. Abundance, species diversity, size of snags, and number of tree cavities in the single-tree selection stands were significantly higher than sheltered-wood stands.

AbstractForest soil and litter is inhabited by a diverse community of animals, which directly and indirectly rely on dead organic matter as habitat and food resource. However, community composition may be driven by biotic or abiotic forces, and these vary with changes in habitat structure and resource supply associated with forest land use. To evaluate these changes, we compiled comprehensive data on the species composition of soil animal communities and environmental factors in forest types varying in land-use intensity in each of three regions in Germany, i.e., coniferous, young managed, old managed, and unmanaged beech forests. Coniferous forests featured high amounts of leaf litter and low microbial biomass concentrations contrasting in particular unmanaged beech forests. However, soil animal diversity and functional community composition differed little between forest types, indicating resilience against disturbance and forest land use. Structural equation modelling suggested that despite a significant influence of forest management on resource abundance and quality, the biomass of most soil fauna functional groups was not directly affected by forest management or resource abundance/quality, potentially because microorganisms hamper the propagation of nutrients to higher trophic levels. Instead, detritivore biomass depended heavily on soil pH. Macrofauna decomposers thrived at high pH, whereas mesofauna decomposers benefitted from low soil pH, but also from low biomass of macrofauna decomposers, potentially due to habitat modification by macrofauna decomposers. The strong influence of soil pH shows that decomposer communities are structured predominantly by regional abiotic factors exceeding the role of local biotic factors such as forest type.

Forests in Europe are, at present not endangered by soil erosion, however, this can change with climate change or intensified forest management practices. Using a newly established network of plots in beech forests across Europe, the aims of this study were 1) discrimination of soil properties and erodibility indices in relation to bedrock, 2) determination of geochemical properties and Corg influencing erodibility, and 3) assessment of the effect of soil depth on erodibility indices. Seventy-six soil samples from 20 beech forests were collected in 11 countries to quantify soil properties influencing erodibility indices clay ratio, modified clay ratio, sodium adsorption ratio, and oxides ratio. Results indicate that dominant soil properties, determined by bedrock, that correlate with forest soil erodibility indices are: Corg, pH, EC, Ca and Na ion concentrations, total-water soluble cations, and the % of sand. According to the tested indices, soil susceptibility to erosion follows the sequence: granite>andesite>sandstone>quartzite>limestone. Deeper soil horizons on granite are more susceptible to erosion than surface horizons, while this is not the case for soils on limestones. In conclusion, forest management should consider the predisposition of different soil types to erosion.

A new motpellier maple (Acer monspessulanum L.) site was described in this paper, located on mountain Boranja, in forest management unit ?Istocna Boranja?, above Roguljski potok, on Glogovita kosa ridge. Montpellier maple occurs on elevations between 460 and 480 m a.s.l., on southwestern and western aspect, on very steep slopes with inclination 45? t? 50?. The site area is 874 m2, ?nd coordinates of site centre are: ?=19?13?49.0? and ?=44?25?21.33?. In this site, Montpellier maple occurs in a plant community of hop-hornbeam and manna ash, and considering that Montpellier maple was recorded in all three layers, and that it occurs abundantly in shrub and ground layers, a subassotiation with montpellier maple was set apart (?stryo carpinifoliae-Fraxinetum orni subass. ?ceretosum monspessulanii). According to floristic composition, most plant species belong to the submediterranean floral type, so this community represents an enclave of submediterranean vegetation in the belt of continental beech forests. The community is of azonal character, orographically-edaphically conditioned, and occurs in warmer aspects, on shallow and skeletal rendzina on oolithic limestones.
