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 speciesNorway 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)

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

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
