Effective river ecosystem management requires that the existing hydrologic regime be characterized in terms of the natural hydrologic regime and the degree to which the human-altered regime differs from natural conditions. This is known as Range of Variation Approach (RVA) and can be used for variation of stream flow, range of variation and appraisal of dam impacts on riparian zones. In this pa...

Exotic plant invasions have triggered environmental and economic problems throughout the world. Our ability to manage these invasions is hindered by the difficulty of predicting spread in fragmented landscapes. Because the spatial pattern of invasions depends on the dispersal characteristics of the invasive species and the configuration of suitable habitat within the landscape, a universal mana...

The lack of management experience at the landscape scale and the limited feasibility of experiments at this scale have increased the use of scenario modeling to analyze the effects of different management actions on focal species. However, current modeling approaches are poorly suited for the analysis of viability in dynamic landscapes. Demographic (e.g., metapopulation) models of species livin...

Quality of urban areas and improvement of it have always been considered as one of the main issues in the process of urbanization. It might be possible to consider this importance as the result of fundamental changes in intellectual patterns during the past two decades in one side and its proposal in all aspects of human life on the other side though this is one of the main influential concepts...

Landscape visualizations are pictures of real places seen in perspective that show visible or non-visible features or recognizable landscapes in the future, the present, or the past. This paper is intended to provide an introduction to landscape visualization technology for rural communities, planning professionals, and educators who are interested in, but are generally unfamiliar with, the use...

The report presents metrics as an approach for supporting the management of an application landscape by quantifying specific structural aspects. It derives basic guidelines for the construction of such metrics from a comparison of current application landscape metrics to metrics in software engineering and business administration. Thereby, it puts a special emphasis on integrating the metrics i...

Stress management is considered as an important factor in nowadays landscape. Therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (Lolium...

Planning for land use development, protection of good quality agricultural land, land degradation management and many other resource management issues requires reliable land resource information. Enhanced Resource Assessment (ERA) techniques were employed to rapidly assess and predict soil and landscape attributes throughout Cooloola Shire in South East Queensland. ERA uses landscape modelling ...

Adaptive management is a form of structured decision making designed to guide management of natural resource systems when their behaviors are uncertain. Where decision making can be replicated across units of a landscape, learning can be accelerated, and biological processes can be understood in a larger spatial context. Broad-based partnerships among land management agencies, exemplified by La...
