Pre-proposal No 4 ENHANCEMENT OF CARBON AND WATER RELATED REGULATORY FUNCTIONS
OF FORESTS THROUGH PATTERNS OF PRIMEVAL FORESTS DYNAMICS
Objectives:
Spatial variability of carbon from the atmospheric CO2 in primeval forests ecosystems, and mainly in their soil component, will
be analyzed, because the main resident time of carbon in deep soil layers may well exceed several hundred years (Persson et
al. 2000), and, unlike climax above earth biomass can hardly be increased, soils represent a reservoir still unsaturated.
We ascertained that the organic carbon concentrations in soils copy the spatial INTAS Thematic Call with ESA 2006 Page 19
INTAS Ref. Nr 06-1000025-9144 distribution of trees necromass down to minimum 50 cm. A combination of these findings with
the measurement of the soil and slope deposits thickness will facilitate development of models for nature based management of
forests of all categories. Results will be used in action 5.
Methodology:
Advanced sampling designs based on known processes and variograms will be employed, along with state-of-the-art devices
(Vario Macro elemental analyzer, BIO-plates).
Task Input:
The task is depending on: Synthesis of prior knowledge and identification, selection and screening of permanent research plots
• set of the permanent research plots
• inventory of forest functions
• results of prior research
Result, milestones:
• maps of carbon stock in primeval forests soils: 31 October 2008
4.2.4 Task Title:
Modelling of a controlled application of additional new natural dynamics components
Task coordinator:
Prof. Milan Saniga , belonging to team: SRT
Objectives:
Controlled application of primeval forests dynamics in managed forests must be preceded by modeling with the help of advanced
forest models subject to past lowintensity management (for various reasons), but in particular in the buffer zones of nature
preserves, where there has been a constant interaction between natural processes and human intervention. Thus the overall picture
will be compiled from the results of modeling and forest functions screening performed at different times and in forests at
various localities in various developmental stages.
Methodology:
Sibyla tree growth model (Fabrika, ëursk˘ 2005), Hydrus (Simunek et al. 2004) – a tool form modeling water and solutes transport
in soils, as well as BIOME BGC (Thornton et al. 2002) model for studying biogeochemical cycles of carbon and nitrogen,
and screening of forest functions in permanent research plots.
Task Input:
The task is depending on : Field research on water and solute transport in forest slopes and their stability, the models leaning
on data acquired in actions 1., 2., 3., 4. as the model input.
Result, milestones:
Functional assessment of natural processes:
• modelling reports
• Validated proposals of enhancement of carbon accumulation by 20%,
• Validated model of retention and accumulation of water in forests
