General System description

System name: Montado ecosystem management decision support system

Acronym: MfLOR

Brief overview

MfLOR is a tool that may support both cork and holm oak forest management planning and scenario analysis.

Scope of the system

The tool in its current version provides information to support scenario analysis applied to cork oak forest ecosystems in Southern Portugal.

System origin

The system was developed in 2007/2008 by the Centre of Forest Studies of Instituto Superior of Agonomia (CEF/ISA) of the Technical University of Lisbon in the framework of Project INTERREG IIIA “Desarrollo de un sistema de información para la gestión ambiental y económica del ecosistema dehesa/montado en Extremadura y Alentejo. 2ª Fase” and by Project PTDC/AGR-CFL/64146/2006 “Decision support tools for integrating fire and forest management planning” funded by the Portuguese Science Foundation.

MfLOR is used by the Portuguese Ministry of Agriculture Regional Office of Alentejo (DRAPAL) to support cork and holm oak regional scenario analysis. The cork and holm oak covertypes extend over an area of approximately 1 million ha.

Support for specific issues

The system was designed so that it might support both management planning and regional analysis. Its current implementation provides information about potential timber, cork and revenues flows as well as about carbon stocks in an area of about 1 million ha in Southern Portugal. The user may specify the time period and may assess tradeoffs between target flows and stocks.

Support for specific thematic areas of a problem type

• Silvicultural
• Conservation
• Restoration
• Development choices / land use zoning
• Policy/intervention alternatives
• Sustainability impact assessment (SIA)

Capability to support decision making phases

• Intelligence

The GUI helps the user define the scenario analysis/management planning problem (e.g. by identifying goals).

• Design

The GUI provide guidance to define the model that best addresses the decision-maker goals (e.g by identifying activities or decision variables, objectives and constraints).

• Choice

The LP solver and the GUI help select strategies.

• Monitor

No support is provided.

Data and data models

Typical spatial extent of application

The system may be used both for management planning (stand and/or landscape-level) and regional analysis. It may address both single and multiple decision makers contexts (yet it does not include specific tools to conduct negotiation processes)

Forest data input

The system may use both individual tree level data and stand level data from sample plots. It uses gis information (vectorial). It may further use financial information (e.g. prices, discount rate)

Type of information input from user (via GUI)

The user may input a) expert knowledge to define prescriptions/strategies, b) simulation period, c) financial data and d) goals and production objectives

Models

Forest models

The system integrates new cork and holm oak growth and yield models – SUBER v. 4.0. This model provides estimates of cork and timber yields. It further provides estimates of carbon stocks in the tree above the ground.

Decision Support

Definition of management interventions

The user may define all cork and holm oak silviculture parameters e.g. harvest (timing of clearcut if it is a regular stand, timing and intensity of thinnings, timing of cork extraction) and regeneration parameters. The prescription writer provide an interface for the suer to input this information and it automates the generation of management options.

Typical temporal scale of application

MfLOR was designed to support strategic management planning and scenario analysis.

Types of decisions supported

• Management level
  • strategic decisions
• Management function
• Planning decisions
  • organizing decisions
  • command decisions
• decision making situation
  • unilateral
  • collegial

Decision-making processes and models

MfLOR uses a linear programming model.

Output

Types of outputs

Results are reported in tables and in maps.

Spatial analysis capabilities

The system has spatial reporting capabilities. Yet it does not include spatial analysis functionalities. It provides standard data import/export formats (GIS, spreadsheet, relational database)

System

System requirements

• Hardware requirements: 2 GHz Pentium IV, 1024 Mb of RAM, 250 Mb of hard disk, CD-ROM reader
• Operating Systems: Windows 2000, Windows XP or Windows Vista
• Other software needed: the user does not need to acquire additional software.
• Development status: completed

Architecture and major DSS components

MfLOR is a desktop application with a modular structure. It was developed with software Ms VB.NET.

The system includes a MS Access 2003 relational database (INfLOR 2.1), a simulator with cork and holm oak growth and yield models – SUBER v. 4.0, a prescription writer, an LP matrix generator, and a report generator. It further includes freeware (GIS and LP solver). A GUI ties all modules together to provide the user-schema.

Usage

Government use (Portuguese Ministry of Agriculture Regional Office of Alentejo (DRAPAL))

Computational limitations

Run time is impacted mostly by the number of prespcritons (LP variables). This depends on a) the number of stands b) the lenght of both the planning horizon and the planning period and c) the flexibility when defining prescriptions.

User interface

Describe the quality of user interface and the Prerequisite knowledge for using the system

Documentation and support

The graphical user interface provides access to the MfLOR users' manual:

Installation
