DSS-WAMOS
(Decision Support System - WAldMOorSchutz)
dialogue-orientated, computer-aided derivation of an
individual, optimal recommendation of action for
renaturation of mires in the forest
DSS-WAMOS – Main Task
DSS - WAMOS – A Decision Support System for Management of Mires in the Forest 13th International Peat Congress - Tullamore, 9th June 2008
Main characteristics:
– low investigation effort and data requirement (standardized peatland mapping procedure)
– High transparency and easy usability (dichotomous decision trees)
– provision of expert knowledge and decision-relevant expertise (Dialogue section)
– representation of existent insecurities and additional investigation requirements
DSS-WAMOS – Requirements on the DSS

Object of investigation
Definition - Forest Mire:
„ Forest mires (in terms of DSS-WAMOS) are defined as mires (with or without wood) connected to forest. The catchment area is
predominantly covered with wood - which has a significant impact on the water supply situation of the mire.“
DSS - WAMOS – A Decision Support System for Management of Mires in the Forest 13th International Peat Congress - Tullamore, 9th June 2008
DSS - Appliance
DSS – WAMOS is applicable for fens and transitional mires:
• water rise mires, terrestrialisation mires, percolation mires spring mires and kettle hole mires
• sphagnum -dominated ombrosoligen slope bogs (at least partially water-fed from catchment area, straight water flow, no heavy bulge, no heavy modification of surface by peat cutting)

Derive adequate forestal measures in order to increase water supply from
catchment area
Identification of appropriate rewetting techniques in dependence of site
conditions and development objective
Recommendation for treatment of undesired self-afforestation of the mire
DSS - Basic Structure
Task: – derive adequate forestal measures in the catchment area
Decision relevant parameters:– abundance and composition of forestal skirt bordering the
mire – composition of forestal species in the catchment area– age structure of pine-forests in the catchment area (fellable
age yes/no)– kind of intended holding of forest area in the catchment area– existance of specific kinds of species and biotope that need
to be preserved
Task: – derive of adequate maintenance measures in the mire
Decision relevant parameters:– kind of current use– species of mire grove– existance of specific kinds of shadowing-sensitive
vegetation that need to be preserved– hydrostatic type of mire / oszillation ability – abundance of hypnum moss– longterm warrantee maintenance– abundance of mire grove– pine-needle (short-needle / long-needle)
