Abstract. Lately, as sustainability has been globally a key goal at local and
regional level, environmental governance and management issues, related to
decisions that verify performance have also gained a continuously growing
focus. DSSs designed for this purpose can use multi criteria analysis and
indicators to implement sustainable forest management. This DSS application
includes 6 variables for the forest and by using the specific programming code
based on If – Then statements of Visual Basic, automatically selects and
decides management measures to propose to the forest manager as an output
for each variable. This happens by estimating the interaction of different
variables in the forest, which concerns the allowance or conflict case of two
different uses. The manager can accept, reject or complete the proposed
measures. Such a DSS application can easily be connected to other software as
GIS or CAD and can easily be expanded to many new technology applications.
Keywords: DSS, environmental governance, multi-objective forest
management
1. Introduction
Governance constitutes a distinct policy regarding management issues and
designates processes which focus on decision making and indicates the total sum of
given and anticipated mechanisms. Decision support technologies have lately been
widely used in many scientific fields and this diffusion affords many gains either to
researchers or to the administrators. A Decision Support System (DSS) is a
computer-based information system that supports business or organizational
decision-making activities. DSSs serve the management, operations, and planning
levels of an organization and help to make decisions, which may be rapidly changing
and not easily specified in advance (Power, 2000). Information and Communication
Technologies (ICT) is a discipline that can adequately be exploited for environmental
management issues, such as wild flora and fauna management, aiming to help local
authorities/administratives in decision-making process (Papastavrou et al., 1999). It
is based on the specific administrative targets set and also aims to select the most
suitable measures for their achievement. Environmental governance in Greece is

entrusted on Public Forest Services, enterprises who are working with stakeholders
and other non profit Organizations. Lately, as sustainability has been globally a key
goal at local and regional level, environmental governance and management issues,
related to decisions that verify performance have also gained a continuously growing
focus DSSs in forest management are adaptable for small private holdings, large
public properties or cooperative management across multiple ownerships (Twery et
al., 2005). In recent research (Andreopoulou, 2000, 2009) regarding the introduction
of informatics in Forest Service, it is estimated that the use of new information
technology tools is the only process to meet the extended needs of the local forest
units to protect forest ecosystems. Forest service in Greece is a non-profit
government organisation. It is a sub-division of the Ministry of Environment, Energy
and Climate Change and plays an important role in the sustainable exploration of
forest areas and furthermore, the preservation of forest character. As forests and
forest areas cover almost 20% of the area in Greece, the multiple roles of forests
imposes the existence of several task divisions in a Forest district office, such as
forest management, wood production, forest and wild life protection, forest technical
constructions, treatments, reforestations, recreation, forest-related legal issues,
administration and economics. All the above activities create a variety of
administrative jobs towards the central service in the Ministry of Environment,
Energy and Climate Change, to the Prefecture Forest Administration Department, to
Regional Forest Service, other services or the local population. There are also many
administrative and statistic books that need to be completed continuously. Therefore,
the personnel are due to paperwork for administrative purposes that have to handle
within timetables. For example, findings from the research in the Region of Epirus
reveal that the forestry public sector has not reached high rates of adoption mainly
concerning infrastructure, hardware, and LANs (local networks) and moreover, there
is a certain lack in personnel’s skills and education as to computer literature
(Andreopoulou, 2011). Promotion of Information and Communication Technologies,
including DSSs, will offer better administration results, helping sustainable forest
management.
Forest ecosystems have several functions such as: a) Source of timber products
and firewood, b) Wild fauna’s biotope and habitat for fresh water fish, c) Water
source and soil protection, d) Habitat for range-plant growing, e) Land with great
biodiversity and f) Recreation sites. Nowadays, forests are often managed for
multiple uses (Seely et. al. 2004). Forest planning is a very complex activity because
there are many goals, which should be achieved simultaneously and a lot of
components and elements, which must be considered (Tasoulas, 2011). Modern
forestry mostly focuses on environmental sustainability of the ecosystems in
relationship to the citizens as a result of the current change in both urban and rural
areas (Helms, 2002).
A method for the measure choice in forest management is multi criteria analysis.
In this case criteria and indicators are primarily used in implementing the principles
of sustainable forest management at national, regional, and at forest management unit
levels (Wolfslehner et al. 2005). The factors that must be reviewed, affect forest
policy selection, including the nature of goods and services, social values, and
economic values (Cubbage et al., 2007). In planning forest ecosystem management,
evaluations of alternative plans with respect to ecological values are usually based on
592
a set of variables describing the forest and the relationships between the variables and
ecological values is assessed on the grounds of expert judgments (Leskinen et al.,
2003, Baskent et al., 2008). By using a DSS in forest management, administrators can
achieve exploiting natural resources, focusing on sustainability and respect to
biodiversity so great benefits can be offered to society (Tasoulas et al., 2010). The
multiple benefits from forests and generally from natural environment can only be
achieved by using tools of new technology and new daily workflow within Forest
Service, aiming to increase the productivity of human resources, has to be redefined
through the use of computers and network tools and techniques (Andreopoulou
2009).
This paper describes the planning and development of software for a DSS
application, aiming to support the administrator/manager of Forest Service or
stakeholder to properly manage forest ecosystems. In the DSS the manager will
import data for all parameters as variables of the forest into the programme and after
the elaboration of the system, specific management measures will be prompted for
him to choose. This application includes a Data Base Management System
(D.B.M.S.) for handling of stored data. It can be used by the National Forest
Services, enterprises working on forest management and foresters that work in other
Organization relative to this field. This work constitutes a part of a doctoral study,
which is held on Laboratory of Forest Informatics, at Aristotle University of
Thessaloniki, Greece.
2. Materials and Methods
The programming language that was selected to develop this DSS was Visual
Basic and the platform of software that was used is Visual Studio.NET of Microsoft.
Visual Basic constitutes a part of Visual Studio.NET as also other languages do.
Visual Basic.NET (VB.NET) is an object-oriented computer programming language
that can be viewed as an evolution of the classic Visual Basic (VB) which is
implemented on the .NET Framework. Visual Basic was chosen because it does not
require advanced training and can be quickly assimilated and used (Plant and
Murrell, 2007). Microsoft Visual Studio is an integrated development environment
(IDE) that can be used to develop console and graphical user interface applications
along with Windows Forms applications, web sites, web applications, and web
services in both native code together with managed code for all platforms supported
by Microsoft Windows, Windows Mobile, Windows CE, .NET Framework, .NET
Compact Framework and others.
In Visual Studio.NET, Project or Solutions are the fundamental screens of
designing. The designer works new projects on Solution Explorer and Properties
windows, using mainly Windows Form Designer and Toolbox. The programming
steps for developing applications are a) Design the interface of the program b) set the
properties for each element and c) write the source code.
During the source code writing, procedures as Private or Public Sub were
developed, structures if-then-else and select case and loops do-while and do-until
were used to express the queries for the variables.
593
The Data Base Management System was developed in Microsoft Access and
connected to the application by the ADO.NET method.
The data that must be imported to the DSS Application pertains to the several
functions of forest ecosystems and are categorized to six basic variables:
1. Timber management
2. Wildlife management
3. Mountainous water resources management
4. Biodiversity
5. Grassland management
6. Recreation areas
The raw data of these variables must be ad hoc collected in the forest and be
available to specified users for insertion into the fields of the DSS application. The
role that an expert will play in organizational decision-making by using a DSS is
very important and cannot be substituted by non experts (Diasio et. al., 2009). That is
why the insertion of the data in the program demands foresters with management
experience.
Some basic calculations on forest variables refer to the estimation of the standing
timber volume, the stand structure, the wildlife, the determination of the maximum
hunting bag, the degree of roundness of the basin, the maximum quantity of the
cascading water, biodiversity, the ordinary use of the grassland, suitable areas for
human recreation and many other which are interlaced into the forest. For choosing
the appropriate measures for the forest ecosystem, many uses concerning these six
variables were recorded and the interaction between them was recorded too. The
criteria for the proposed measures concern the allowance or the conflict case of two
different uses that should take place simultaneously. Indicatively, uses that can take
place at the same time is timber production and hunting or water production and uses
that conflicts are protection of rare species of flora and deforestation or soil erosion
and grazing.
3. Results
The DSS application that was planed and developed is composed of 20 different
screens including over 300 components. The DSS application must be user-friendly
aiming to be used from non-computer literate users as many foresters are, so the
interface that was developed has served these assumptions. The first screen of the
application is a typical window screen, with basic information such the name of the
program and folding menus as File, Management and Suggested Management
Measures (Fig. 1).
594
Figure 1.The introductory interface of the application
After the introductory screen, the forest administrator/manager can skip into six
other screens, each for every parameter/variable and insert all the needed data
(Fig.2). These data must already have been collected from the forest that is studied,
under the directives of the administrator. In every phase of the insertion of the data,
there is a button that appears a help screen which provides the necessary guidelines
to the user how to fill the fields in each screen.
Figure 2.One of the six parameters/variables screens of the application
595
As the insertion of data is completed and by clicking the proper button in every
screen for acceptance, the program automatically performs the respective
calculations and transfers the records to the database. Every record is programmed to
be inserted in the appropriate table which has been planed for this purpose. There, by
using the specific programming code which is based on If – Then statements of
Visual Basic, the application automatically selects and decides specific management
measures to propose to the administrator as an output for each variable. These
measures derive from the processing of inserted data, which are analyzed based on
the interaction of the data that manager has introduced. This interaction concerns the
allowance or conflict case of two different uses in the forest. The suggestions appear
to the user either on message boxes during the filling of each field (Fig.3), or by
opening the screen for the proposed measures. In this screen specific check boxes are
already checked depending on user’s inserted data (Fig.4).
Figure 3.Message Boxes for allowance or conflict case of two different uses
Figure 4.The screen of the suggested measures for a variable
596
During decision-support process, the forest manager can accept the suggested
measures or reject some of them, based on other specific needs that the application
can’t read and introduces more measures. At last appears a final screen, with all the
management measures gathered, ready for printing.
Figure 5.The screen of the recommended measures by the DSS
Verifying the actual use of the presented DSS application by people involved in
forest management, data for the co-owned forest ecosystem of Tetrakomo in
Prefecture of Arta, Greece, were inserted in the DSS, concerning the six variables
that were mentioned. These data were taken from the approved management plan of
this forest. The DSS application transferred the data properly into the data base,
proceeded to the required calculations and finally recommended specific measures to
the forester (Fig. 5). The measures, which are presented in the final screen, were
totally accepted by the forester of the enterprise that is responsible for the
management plan of this forest.
4. Discussion
The DSS application that was developed is an independent window application,
which can be installed to every modern computer and it is not yet connected to any
other software. It may have 20 different screens including over 300 components, but
it is user-friendly, based on the usual interface of most common window programs
and can be used as a tool for multi-purpose forest management. Such a Decision
Support System must do, this one supports by using specific criteria and indicators
the Forest Authorities/Administrators to select the appropriate measures for
sustainable multi-objective management for forest ecosystems. This happens by
analyzing the interaction which concerns the allowance or conflict case of two
597
different uses in the forest. The proposed measures can be accepted, rejected or
completed by the forest manager-user of the application. That is because DSSs can
not decide the measures instead of human mind, but their role is to support by
processing a big store of data, make modeling calculations, revealing many aspects
of the situation and at last propose specific measures. Human mind is indispensable
and that’s why it takes the final decision. Although the more comprehensive
knowledge and analysis of the data, the better results for the administrator in
adopting management measures for the forest ecosystem.
The programming code of Visual Basic.Net is the tool that has been used for
processing the inserted data, making the connection with the database and permits or
forbid specific actions, which conform or clash between two ore more different uses.
This analysis in cooperation with the DBMS offered the application the feasibility to
analyze a big store of data in short time (Elmasri and Navathe, 2004), reaching the
proposal of specific measures after the exclusion of many others. Finally that is what
why it is classified at the DSS systems.
The application interface is presented in the Geek language because it deals with
the multi-purpose management of Greek forest ecosystems. Forest ecosystems in
Greece are characterized by intense biodiversity and that imposes the 6 different
topics to be dealt with. Therefore, foresters in Greek Forest Service will have to deal
with management issues and they constitute the target audience of the application. A
future extend of the application would be the creation of multiple versions of
the interface, in other languages, such as an English version, a German version, etc
aiming at being extensively used. However, changes have to be made also in the
original code of the application aiming at fulfilling the managerial needs of other
type of forest ecosystems, too, except of Greek forest areas.
5. Conclusions
The National Forest Services, enterprises working on forest management and
foresters that work in other Organizations, can easily use that DSS application. As
information and communication technologies (ICTs) are key elements supporting the
growth of e-governance initiatives and projects, using this DSS in forest
administration helped forest managers to achieve exploiting natural resources with
focus on sustainability, with respect to biodiversity, by gaining great benefits for the
forest owner and the whole society.
It includes open source code, which can be upgraded in the future when new
management techniques will come to the front. It is compatible to various software
platforms; it can be connected to Geographic Information Systems (GIS) by using
dynamic link libraries (Sugumaran, 2002) and other software, so that in the future the
data can acquire spatial information. At last it can be easily expanded to many new
technology applications such as Internet, i-Pads and i-Phones to gather information
and communicate at once with multiple users. Conclusively a DSS is an appropriate
application for the Forest Administration, which can seriously contribute to a better
598
management of forest ecosystems and provide many scopes for improvement taping
the future extends in information technologies to forest management’ s account.
