Although numerous studies have focused on the dynamics of coarse woody debris (CWD) in boreal Fennoscandian forests, information on CWD in streams remains limited. To achieve a better understanding of CWD dynamics in streams we compared amounts and characteristics of CWD between streams and adjacent riparian forests in old-growth and managed forest sites, respectively. We also identified distances to the sources of CWD and evaluated these in relation to the lateral zonation of riparian trees. CWD volumes found in the stream channels were related to, but exceeded, the volumes found in the adjacent forest. In-channel volumes separated by species were better correlated with terrestrial volumes of CWD than with volumes of living trees. Tree species appeared to be zoned across the riparian zone, with slightly higher abundances of deciduous trees and lower abundances of Scots pine trees close to the stream. Similar to upland forests, riparian forests were dominated by coniferous tree species, mainly Norway spruce (Picea abies (L.) Karst.). These findings suggest large similarities in CWD input between streams and riparian forests and substantially slower decomposition rates in stream channels compared with those in riparian forest. The results provide an improved basis for creating reliable models of CWD supply and maintenance in streams based on knowledge of forest development and CWD dynamics in the terrestrial environment. Site productivity could potentially be used to predict CWD volumes in stream channels under pristine conditions.

Production of raw wood material and its regulation has a great ecological and economic importance in every country. The aim of the paper is to analyze the prospective production of raw wood with respect to the expected basic tree species composition and assortment structure on an example of long-term development of selected indicators of forest condition in Slovakia. For this analysis we used data on the area, growing stock and planned decennial timber felling in the forests of Slovakia in 1980, 1996 and 2003. The production potential of forests was evaluated on the basis of the annual perspective allowable cut by 2020, from which the prospective production of assortments was derived using the models of assortment yield tables of tree species. The results show that in the forests of Slovakia there is an about half proportion of coniferous and half proportion of broadleaved tree species, very good structure of growing stock as well as its trend in the last years. Production of raw wood assortments for industrial processing for the years 2010–2020 is limited by the volume 6.3–6.4 mil. m<sup>3</sup>. About one half of this volume comes from coniferous and the other half from broadleaved tree species. For coniferous tree species the proportion of spruce and fir is 87% and for broadleaved tree species the proportion of beech and oak is 80%. For coniferous tree species sawmill assortments have a decisive, almost 70% proportion. Regarding broadleaved tree species, pulpwood assortments with 47% proportion prevail, although with 11% the highest quality assortments for the production of veneer from beech and oak are also significant.

Species Specific

We sowed seeds of Pinussylvestris L., Pinuscontorta Dougl, Piceaabies (L.) Karst., and Piceamariana (Mill.) B.S.P. at five different virgin peatland sites in northern Sweden. Seeds were sown in 1987, 1988, 1989, and 1990. The seeds were sown in three different types of microhabitat, viz Pleurozium, Sphagnumfuscum, and Sphagnumangustifolium. Germination and seedling mortality were monitored each year. Both germination and mortality were significantly affected by the micro-habitat. Sphagnumangustifolium microhabitats were most favourable and Pleurozium microhabitats were least favourable for germination of all tree species. In contrast, the mortality for all tree species was highest in Sphagnumangustifolium microhabitats and lowest in Pleurozium microhabitats. Lowest average mortality was found among the nonindigenous Pinuscontorta and Piceamariana. The coniferous tree species had a species-specific relationship with the microhabitat. Pinussylvestris seeds were the most able to germinate in the Pleurozium microhabitats, and seedling mortality was strongly affected by the microhabitat. Piceaabies was the least affected by the microhabitat, and seedling mortality was high irrespective of microhabitat.
