Content of presented paper consists in detailed description of findings having been obtained up to now during evaluation of national European beech provenance plots series 1995. Mortality, height growth, stem form and phenology of individual tested beech provenances, have been evaluated at the age of 5 - 9 years.

Prosperity of six tree species was investigated in juvenile-stage forest stand. An experimental plot was established at an altitude of 520 m a. s. l. on Fagetum acidophilum site which had been used as meadow till 2001. Coniferous species mortality did not exceed 5% and broadleaves species mortality was less than 9% in the 8th year after planting. Douglas fir was the only unmixed conifer which was significantly higher (456 cm) compared to Douglas fir mixed with other species. On the other hand, sycamore maple was significantly higher (325 cm) in mixture. Unmixed spruce, beech and fir did not differ from mixed variants. As for DBH, mixed larch, unmixed Douglas fir and mixed sycamore maple are the thickest species (67, 57 and 22 mm respectively). Studied conifers seem to be much more efficient in terms of forest environment restoration.

Monitoring of successive stages of alder stands (Alnus glutinosa) from natural regeneration on abandoned agricultural lands was realized in 2008 and 2009. Analysed alder stands arose on silt deposition after local flooding in 1998. Stand analysis were realized on the circular plots (10 m2 each) in regular networks. Alder dominated in both stands. Basic stand characteristics differed due to different stand density, dimensions of the mean stems were similar. Density of living trees varied from 11.6 to 24.4 thousand pcs per ha, stand basal areas were 20 a 43 m2/ha. Thin trees dominated in both stands, high production potential indicates the thickest trees (over 10 cm). High number of trees positively influenced tree quality. Measurement did not confirm the relationship between light and stand density on circular plots. Vital weed occurred on both stands.

The study aims to contribute to knowledge of hydrodynamic processes in a soil profile of mountain-humic podzol under small-pole spruce stand. Method is based on investigation of hydrological balance of 60cm topsoil. Totally 144 tensiometers placed in different depths (15, 30, 45 and 60 cm) were used to measure suction pressure within square plot of 1are area. Behaviour of gravitation water in macropores (hydraulic head of groundwater table) was investigated using a piezometer pipe put into a drill well. Thorough hydropedological investigation was conducted to obtain parameters needed for hydrological balance calculation. The study quantifies regime of hydrodynamic processes in the mountain podzol during growing period 2007 and reveals a dominant influence of rainfall on water flow in an aerated zone of the soil.

The paper recapitulates history, knowledge and legal-economic fulfilment of the research-application project for complex management of two demonstration watersheds Řehucí and Vilčok within perimeter of water-supply reservoir Šance in the Beskydy Mts. The principal project of top world level proved feasibility of complex hydrologic service of forest management in protection zones of water resources and its continual sustainability. The project concurrently added to presentation of detention hydrologic service of forest management in mountainous protected region of natural water accumulation.
