Forest Vegetation Simulator Disturbance Database

A public version of the Forest Vegetation Simulator (FVS) Disturbance Database (FVSDDB) is available containing FVS disturbance simulation outputs. The database contains no proprietary and/or sensitive information and is derived from FVS analysis of the Forest Vegetation Simulator Ready Database (FVSRDB). The Public FVSDDB includes disturbance analysis outputs covering all FVS Variants at multiple severities and time-steps:

• Disturbances
  • Fire
  • Insect and Disease
  • Wind
  • Mechanical Add
  • Mechanical Remove
• Severities

  High

  (>75% above ground mortality)

  Medium

  (25-75% above ground mortality)

  Low

  (0-25% above ground vegetation mortality)

• Time Since Disturbance (TSD)
  • Initially after disturbance
  • 3-5 years post disturbance
  • 8-10 years post disturbance

Outputs archived in the Public FVSDDB include predefined outputs used for stand/plot analysis post disturbance using the STANDSQL keyword in FVS. More detailed output data descriptions can be found in the Essential FVS Guide.
