Opis:
The main aim of study was to present the stock and structure of deadwood in different site conditions. In total. sixteen study plots were established on wet broadleaved forest (Lw) and riparianalder forest (OlJ) sites. The objective was to determine the carbon accumulation in lying dead trees. The investigation was performed in the Czarna Rózga reserve in Central Poland (50°5937N; 20°015E). All live and dead trees were measured on each plot. The species of both live and dead trees were identified as well, and the decay class of the dead trees was assessed. Additionally, samples of different species wood from lying logs in five decay classes were taken for carbon content determination. The study was carried out in the spring of 2017. The average stock of deadwood in the Czarna Rózga reserve on the wet broadleaved forest site amounted to 47 m3/ha, while on the riparian alder forest site it equaled 52 m3/ha. The high stock of deadwood can be explained by the slowdown of decay processes by humidity and anaerobic conditions. Ash was the dominant species in the deadwood pool. Regardless of the site conditions (Lw or OlJ), the stock of ash deadwood was several times higher than the stock of live trees this species. The greater carbon stock in lying dead trees was recorded in riparian alder forest.

Opis:
The objective of the paper was to estimate i) the carbon accumulation in soils of different forest site types as well as ii) its changes with regard to the depth of the soil profile. The investigation was carried out in the Przedbórz Forest District (central Poland) on 43 study plots, including different forest sites – fresh coniferous forest (Bśw), fresh mixed coniferous forest (BMśw), fresh mixed broadleaved forest (LMśw) and fresh broadleaved forest (Lśw). On each plot soil pits were dug and samples for laboratory analysis were collected. The following characteristics were determined in the soil samples: pH, the content of organic C and total N, particle−size distribution, the content of exchangeable Ca, Mg, Na and K, and hydrolityc acidity. The obtained results demonstrated that soils of Bśw, BMśw and LMśw sites characterized by higher carbon accumulation in surface horizon to 50 cm depth compared to the most eutrophic sites (Lśw). The rate of carbon accumu− lation in forest soils depend on the humus type which is connected with species composition of stands. Domination of Scots pine in stand affects the formation of ectohumus and leads to higher C accumulation in surface horizons on Bśw, BMśw and LMśw sites. In soils of Bśw, BMśw and LMśw sites carbon stored in the horizons to 50 cm constitutes 64−94% of the total carbon accu− mulated, while on the eutrophic sites (Lśw) this share amounts to 39−72%. The value of the total carbon stock in soils of fresh forest sites can be estimated on the basis of carbon stock in horizons to 50 cm depth.
