“…In [6] as a special case a decision support system model was presented that takes into account an ecological model of the temporal dynamics of environmental species and inter species interaction; see also [4,5,10,11]. Approaches to environmental dynamics such as the one described in [6] are rigid in the sense that the parameters of environmental characteristics were assumed known initially and fixed which in reality is not possible because the internal dynamics of the species is a characteristic which would not be known by everyone.…”

Abstract. The environments in which agents are used often may be described by dynamical models, for example in the form of a set of differential equations. In this paper an agent model is proposed that can perform model-based reasoning about the environment, based on a numerical (dynamical system) model of the environment. Moreover, it does so in an adaptive manner by adjusting the parameter values in the environment model that represent believed environmental characteristics, thus adapting these beliefs to the real characteristics of the environment.

“…Although the field of fuzzy logic began as a way to model language ambiguities, its ability to quantify ambiguity (e.g., sparse datasets, non-linear and continuous assessment thresholds) in a numerical sense has been supported in industrial and ecological applications (e.g., Chang and Chen 2001 ; Bojorquez-Tapia et al 2002 ). DSS models are useful for ecological assessments because data from different domains, formats, and sources can be integrated to assist in management decisions and understanding (Rausher and Potter 2001 ; Recknagel 2011 ). To develop our DSS models for natural resource condition assessments at UPDE and DEWA, we used NetWeaver™, an object-oriented software application developed at Penn State University (Paterson et al 2008 ; Porter et al 2006 ; Saunders et al 2005 ).…”

We implemented an integrated ecological assessment using a GIS-based decision support system model for Upper Delaware Scenic and Recreational River (UPDE) and Delaware Water Gap National Recreation Area (DEWA)—national park units with the mid-Atlantic region of the United States. Our assessment examined a variety of aquatic and terrestrial indicators of ecosystem components that reflect the parks’ conservation purpose and reference condition. Our assessment compared these indicators to ecological thresholds to determine the condition of park watersheds. Selected indicators included chemical and physical measures of water quality, biologic indicators of water quality, and landscape condition measures. For the chemical and physical measures of water quality, we used a water quality index and each of its nine components to assess the condition of water quality in each watershed. For biologic measures of water quality, we used the Ephemeroptera, Plecoptera, Trichoptera aquatic macroinvertebrate index and, secondarily, the Hilsenhoff aquatic macroinvertebrate index. Finally, for the landscape condition measures of our model, we used percent forest and percent impervious surface. Based on our overall assessment, UPDE and DEWA watersheds had an ecological assessment score of 0.433 on a −1 to 1 fuzzy logic scale. This score indicates that, in general, the natural resource condition within watersheds at these parks is healthy or ecologically unimpaired; however, we had only partial data for many of our indicators. Our model is iterative and new data may be incorporated as they become available. These natural parks are located within a rapidly urbanizing landscape—we recommend that natural resource managers remain vigilant to surrounding land uses that may adversely affect natural resources within the parks.

Abstract.A decision support system model is described to advise nature park managers. It applies dynamic modelling techniques to relate abiotic characteristics of a site over time to species that can be found. For a desired vegetation type it determines how such abiotic factors are to be changed in order to obtain the desired change in the vegetation after some time. The system takes into account an ecological model of the temporal dynamics of species, interspecies interactions, and abiotic factors. Applying model-based reasoning and dynamical systems methods to this ecological model, decision options on abiotic conditions are determined in order to obtain desired vegetation types.
