  1. COST ACTION FP0603: Forest models for research and decision support in sustainable forest management Forest simulation models in Czechia: main developments and challenges WG1 1st Workshop and Management Committee Meeting.Institute of Silviculture, BOKU.8-9 of May 2008Vienna, Austria

  2. Main features of Czech forests • Forest cover (total/share): 2 751 568 ha, 34,9 % • Growing stock, annual growth and cuts: 900 mil.m3, 16.8 m3 y-1, 72 % of the annual growth is cut • Main species:Norway spruce (47.7 %), Pine (13.9 %), other coniferous species (7.4 %), Oak (7,4 %),European Beech (7,2 %), Black Locust (4. 2 %), Birch (4,2 %), Larche (3,8 %), Alder (2,1 %), European Hornbeam (1, 9 %), Ash (1,7 %), Linden (1,6 %), Silver Fire (1.0 %). • Main non-wood products and services: water source protection, soil protection, hunting, biodiversity, recreation • Main risks: wind, pests (bark beetles, Lymantria dispar, Armillaria ostoyae), snow, air pollution, climate change impact. Management and silvicultural characteristics: • simplified species and space structure of forests • low value of original tree genotype • air pollution of montane forests • overpopulation of game species (deers)

  3. Forest modelling approaches and trends Empirical models Main types of models developed • Development of single tree volume models and stem profile models (TREEMODEL) • Standing volume and step profile assessment • Forest management and landscape planning • 3D Forest structure Trends in modelling • The trend has been towards carbon cycle in managed forests • Water cycle and energy flow for ecosystem (landscape) Recent research is concentrating in • Recent research is concentrating in: • Modelling regeneration • Modelling carbon cycle • Modelling water cycle and energy flow • Web-based and GIS-based forest information system integrated with forest model

  4. Forest modelling approaches and trends Mechanistic models Not developed in Czechia

  5. Modelling non-timber products and services ECOVAST method for the evaluation of landscape including forest areas

  6. Models for predicting risk of hazards If there are any models for predicting the risk (occurrence/damage) of hazards (fires, wind, snow, etc), list them. If not skip the slide. • Models (scenarios) for modelling risk of climate change

  7. Simulators and information systems List existing forest simulators or decision support systems • Stand level simulators Standing volume biomass assessment (Field map, http://www.fieldmap.cz/ Include name and reference or web page • Forest level decision support systems Include name and reference or web page New methodology for forest management in structurally rich forest stands (Field map, http://www.fieldmap.cz/ • Process based simulators Long-term experimental monitoring and theoretical modelling of the surface runoff formation in the Sumava and Jizera Mts.(BROOK90 model)(http://www.ih.cas.cz/web_new/cs/ Application of the forest-soil-water model (PnET-BGC/CHESS) to the Lysina catchment (Ecol. Modelling, 1999, 120: 9-30). Include name and reference or web page

  8. Data bases/archives on forest simulation models Are there arny archives or data bases on forest simulation models? List them if not skip it.

  9. Research highlight Carbon cycle in managed forests. Applying a process model to stands of major tree species in central-European forestry. Management of water cycle and energy flow for ecosystem control: the energy-transport-reaction (ETR) model). Model calculation of radiocaesium transfer into food products in seminatural forest ecosystem in the Czech Republic after a nuclear reactor accident and an estimate of population dose burden Estimates of ozone concentration and deposition flux to coniferous and deciduous forests Scenarios of forest management in the Czech Republic, Hungary, Poland and Ukraine Utilization of mathematical models and growth simulators for creating forest management plans and planning the tending felling

  10. Research highlight Long-term experimental monitoring and theoretical modelling of the surface runoff formation in the Sumava and Jizera Mts.(BROOK90 model) Application of the forest-soil-water model (PnET-BGC/CHESS) to the Lysina catchment Recovery from acidification as predicted by the MAGIC model for 14 forest catchments in the Czech Republic (Geophysical Research Abstracts, 10, 2008)

  11. Future challenges • Development of single tree volume models and stem profile models (TREEMODEL) • Forest Focus regulation on developing harmonized methods for assessing carbon sequestration in European forests • Reporting of inventory of emissions by sources and sinks for the sector Land Use, Land-use change and Forestry (LULUCF) and Agriculture in the Czech Republic. • Tools for Sustainability Impact Assessment of the Forestry-Wood Chain • Incorporation of internationally harmonized techniques of forest inventory into the methodology of the Czech NFI • Pilot study on the use of National Forest Inventories to downscale European forest diversity spatial information in five test areas, covering different geo-physical and geo-botanical conditions
