COST ACTION FP0603: Forest models for research and decision support in sustainable forest management

Forest simulation models in Belgium: main developments and challenges

WG1

1st Workshop and Management Committee Meeting.Institute of Silviculture, BOKU.8-9 of May 2008Vienna, Austria


Main features of belgian forests l.jpg
Main features of support in sustainable forest managementBelgian forests

  • Forest cover (total/share): 693.000 ha (23%)

  • Growing stock, annual growth and cuts: 4 106 m³ wood used from own forests,

  • In addition 7 106 m³ wood imported

  • Main species: picea, (scots) pine, beech, birch, oak, poplar

  • Main non-wood products and services: passive recreation, nature protection, biodiversity

  • Main risks: fragmentation, deforestation

  • Management and silvicultural characteristics: small patches, abundant private ownership, high productivity management practices


Forest modelling approaches and trends l.jpg
Forest modelling approaches and trends support in sustainable forest management

Empirical models

No own developments

Recent research is concentrating on mechanistic modelling and decision support


Forest modelling approaches and trends4 l.jpg
Forest modelling approaches and trends support in sustainable forest management

Mechanistic models Which exist :

  • ANAFORE (ANAlysing FORest Ecosystems), growth, C and H2O balance, stand scale

    Main features: rather complex, will become user friendly, includes effects of changing climate (and ozone) and management

  • FORUG: carbon and water balance model, stand scale

  • SECRETS: growth, C and H2O balance, stand scale

  • ASPECTS-WiTCh : water, carbon, nitrogen cycles in plant and soil, and major cations (Na+, K+, Ca2+,Mg2+), anions (Cl-, SO4-, HCO3-) and pH in soil water, vegetation growth, weathering, etc (stand scale)

  • CARAIB : water and carbon cycles, photosynthesis, growth, competition of plant types, plant type/species potential ranges (regional, continental or global scales)

  • C-Fix:Main features:

    Based on Remote Sensing hence Spatially explicit.

    Continental to global scale.

    Includes effects of changing climate, with a coupled carbon – hydrological

    approach.

    Output (GPP, NPP, NEP) available on the WWWeb.

Simulators and information systems l.jpg
Simulators and information systems support in sustainable forest management

Stand level simulators

  • ANAFORE, can be downloadedathttp://www.simfortree.be

    Forest level decision support systems

  • SimForTree: decision support system under construction, based on ANAFORE

  • running Flemish project, http://www.simfortree.be

  • AFFOREST: developed within European project, www.sl.kvl/afforest

  • C-Fix: Operational forest flux production

Slide6 l.jpg

Research highlight support in sustainable forest management

  • Including mechanistic simulation of wood density in function of growth/envirmonment/management (from pipe theory)

  • Multicriteria decision support (allowing multiple goals in finding the ‘optimal’ management

  • Including bayesian optimisation and uncertainty (underway)

  • Application of remote sensing in area and carbon flux estimations using the VEGETATION instrument


Future challenges l.jpg
Future challenges support in sustainable forest management

  • In Belgium forests are very fragmented

  • A lot of small patches are in private ownership without common management practices.

  • Decision support management is needed at the forest patch level.

  • Multipurpose forestry is required in Belgium (because of limited available area). Recreation, biodiversity and nature protection are important forest functions.
