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

DSS - WAMOS – A Decision Support System for Management of Mires in the Forest 13th International Peat Congress - Tullamore, 9th June 2008

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)

Water regime requirements for protection of sensitive habitats (water demand, avoidance of eutrophication)

Derivation of rewetting potential in dependence on climatic and hydro-

geological conditions

Consideration of further forestal, agrarian and fishery use

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)
