Stand models for Romania

Status: Stable | Version: v1.0.0 (2026-08-28)

General description

  • Description: Dynamic stand model for different species in Romania
  • Target Species: Todas las especies (code: ``)
  • Application Region: Romania

Technical characteristics

  • Model Level: Stand
  • Allows Projection: Yes
  • Projection Time Step: 5 years
  • Notes: There is an alternative to this model for simulating 'Business as usual' (BAU) management.

To view the step-by-step sequence of initialization, time projection, and harvest, see the stand-level model calculation flow diagram.

Required variables

To run this model in SIMANFOR, the initial inventory must include the following minimum data:

Plot level (Plots sheet)

  • Inventory and plot IDs
  • regeneration type
  • age
  • density
  • reference age SI
  • SI
  • relative production class
  • canopy cover
  • mixture degree
