WEHAM-Subproject 2: Development of WEHAM scenarios

The potentials of forests and wood products for mitigation, adaptation of forests and forest-based industries to climate change and inclusion of biodiversity conservation targets in forest management are very important parts of forest and climate related policy and decision making. Various conflicts of interest exist, and assessments of current and future management options are needed. WEHAM simulates growth and management of forests and allows for comparisons of expected outcomes of different management scenarios.

Background and Objective

In this sub-project, different scenarios of forest management (based on stakeholder interviews) will be compiled and used in simulations with WEHAM. The results of the simulations will be analysed with regard to sustainability, climate protection and biodiversity indicators.


WEHAM projects the growth of individual trees into the future. The growth equations used are derived from repeated measurements in the National Forest Inventory (NFI). Each tree tallied in the NFI can be included in the simulations. A single tree represents a certain number of trees of the same genus, age and size. According to a given management scenario. the trees are "treated", i.e. some of the represented trees are "cut" and their timber handed over to e. g. a wood products model. The "remaining" trees grow on, til the next modelling step. Depending on the intended analysis, the results can be aggregated from tree to various regional levels (e.g., federal state) and / or other classifications (e. g., age classes).


  • Different scenarios based on results of stakeholder dialogues
  • publication of scenarios and their results on forest management options with the respective ecological limits of ecosystem dynamics and forest growth
  • regional information of scenarios, particularly on forest growth, carbon sequestration and potential timber use
