SUMMARY: Today, at a time of widespread disruption of forest ecosystems, in particular in the lowland forests, the need has arisen for study and research on development of particular structural elements in stands. In this study we investigated the development course of Peduncled oak young growth during seed cutting and immediately after completion, in a forest of Peduncled oak and Genisto elatae with caricetosum brizoides fGenisto elatae-Quercetum roboris caricetosum brizoides/ Investigations were carried out in a pure Peduncled oak stand of preserved structure in the area of the "Karlovac" Forest Office, Management Unit "Rečički lugovi", compartment 16a. In the course of eight years, from 1996 to 2003, the development course of Peduncled oak young growth was monitored with regard to soil influence, stand structure, appearance of shrubs and herbaceous plants, voles and deer game. We determined in which period a particular factor of that forest ecosystem has an effect on natural reforestation. Tending and protection of the Peduncled oak young growth commenced at the right time with its appearance under the crown cover and continued until its transformation into the developmental stage of ´older´young growth, after seed cuttings had been performed. The soil type is hypogley carbonaceous on heavy clay, which, according to the percental contents of humus, belongs to a highly humus soil. Under a 4-5 cm thick spongy layer of inert matter raw humus there is a highly acid A horizon (pH in water 4.1), 5-8 cm thick. According to Braun-Blanquet the degree of soil cover with Carex brizoides amounted to 4.5. The mass of ground vegetation in fresh state amounted to 7.298 to 7.945 kg per hectare. |
