TG5 – Allocation modelling


TG Leader: Katharina Merganicova

Description: This task group will review existing allocation models in forest growth models with regard to tree parts/components included and rules applied in them. The focus is set on the advantages and disadvantages of their usage from the point of modelling the temporal development of forest ecosystems, and data requirements for deriving, calibrating, and validating allocation models. In detail, the following aspects will be addressed:

  • existing allocation models : advantages and disadvantages regarding temporal development, and applied rules (constant ratios, empirical equations, allometric equations, metabolic pool models, pipe model theory, proportional-sink model, etc.)
  • tree parts and components, which are usually accounted for and which are usually excluded (e.g.production of fruits and seeds) –, and their effect on modelled results
  • chapter on allocation models from Forest Growth Modelling book by Marek Fabrika (to be distributed to participants)
  • data requirements for deriving, calibrating, and validating allocation models versus data availability
  • include respiration algorithms in the review, focus on GPP instead of NPP (to be further discussed)
  • case study: compare allocation models in individual models within COST action  (to be further discussed)

Time: collecting and distributing information and final decision on paper aim before next COST meeting in 2015

Products: review paper on allocation models
