Forest fire is an important phenomenon affecting forest ecosystem. It causes essential changes in ecological conditions (e.g. light availability, water and nutrient regime). The aim of this paper is ...to evaluate its impact on soil as well as herb and moss layer of the secondary pine forest. The study area is located in the southwestern part of Slovakia (Borská nížina lowland). Marked changes in physical and chemical soil properties were induced by forest fire. Soils moisture contents were higher in burnt soil probably as a result of increased soil wettability. Infiltration rate decreased on the burnt area due to sealing of pores by ash material. Burning of soil organic matter caused increase in soil pH and available nutrients. In the period of 2005-2007, floristic composition, biomass production and presence/absence of mushrooms were recorded both for burnt and neighboring control areas. Compare to the control stands, especially nitrophilous (synanthropic) species are appearing, first of all Conyza canadensis, Solidago canadensis and Chamerion angustifolium. Also composition of mycoflora is changed - its composition is shifted on the behalf of pioneer and indifferent species. Moreover, the pine natural seeding is obvious here. Information on succession is supported by biomass production estimation.

The contribution is focused upon detail production-ecological analysis of the total herb layer biomass (above-belowground) in the different age stages of the willow stands (soft-wood floodplain ...forest of the Salici-Populetum association) in the Danube river inundation. The basic results vary between 1.3 to 3.1 t per ha according to the age structure and herb layer cover. At all studied forest types, aboveground biomass is higher than belowground one (1.60–7.00 t per ha). The results are compared with those obtained from the Danube and Morava river alluvium.

The paper is focused upon detail production-ecological analysis of the total herb layer biomass (above- and belowground) in four broad-leaved forest ecosystems (Carici pilosae-Carpinetum, Carici ...pilosae-Fagetum, Aceri-Carpinetum and Stellario-Alnetum) near Skalica (Zlatnícka dolina valley) in the Biele Karpaty Mts. Results (Table 2) are discussed and compared with other ones obtained from similar forest ecosystems of Slovakia.

The paper is focused upon detail production-ecological analysis of the herb layer in two floodplain forest categories - transitional ash-poplar and hardwood ash-elm forests. The basic results of the ...total herb layer biomass (aboveground, belowground) are varied in transitional floodplain forests between 800-1600 kg per ha and in hardwood floodplain forests between, 750-1350 kg per ha. At both forest types is essentially higher aboveground biomass than belowground one. Obtained results are compared with other ones in the Danube and Morava rivers alluvium.

The contribution is focused upon detail production-ecological analysis of the herb layer biomass in three oak forests types (the association Carici fritschii-Quercetum roboris ) – type with Molinia ...caerulea agg., secondary forest with Pinus sylvestris and xerophilous type. Obtained results are compared and discussed.
The paper is focused upon detail production-ecological analysis of the total herb layer biomass (above-and belowground) in the various types of the soft floodplain forests on the Danube river. The ...basic results varied between 1 and 5.5 tons per hectare according to the herb layer cover. At all forest types, aboveground biomass is essentially higher than the belowground one (2.52-3.11). The results are compared with other ones obtained from the Danube and Morava river alluvium.
The aim of this contribution is a more detail information about the production of aboveground herb layer and moss layer biomass in mainly coniferous ecosystems (first of all fir and spruce ones) of ...the Spis region - the Slovenske rudohorie Mountains, Spisska Magura Mountains and Levocska kotlina basin. The results of the various parts of the study are compared and discussed
In this contribution authors deal with vegetation vulnerability, methods of its measurements, evaluation and selected stress factors. The basic vegetation types of Slovakia used for evaluation of ...vegetation vulnerability are presented. Possibilities of utilization of such evaluations in landscape-ecological projects are discussed
The aim of this contribution is a synthesis and information about the production of the aboveground herb and moss layer biomass in the pine forests of the Borska nizina lowland. Results are dealing ...with original and secondary pine forests and they are compared with other our secondary pine forests and some pine forests of the temperate zone
The term ecological carrying capacity of landscape is understood in this contribution as a synthetically comprehended special quality expressing the degree of tolerable (suitable) land-use. As ...bearably utilized can be described a territory on which the present utilization disturbs or destroys neither natural qualities, processes and relations among landscape elements (biotic, abiotic, socio-economical), nor the quality of vital environment. We applied this concept of ecological carrying capacity of a landscape to the evaluation of the ecological carrying capacity of the territory of the Tatra National Park and its protective belt. On the basis of a complex evaluation of ecological limits of the territory, we determined the set of variant unlimited activities forming the basis for the estimation of the degrees of ecological carrying capacity of the landscape. The three degrees singled out were characterized in more detail, with respect to the future landscape exploitation, and completed by measures intended to mitigate some negative processes in the landscape, to improve the functional land-use and the environment
