Remote sensing and GIS (geographical information systems) are very important methods for assessment of changes and development of ecosystems in the landscape level. This article deals with applying of remote sensing and GIS methods to assessment of ecosystems in agricultural landscape in the Horňácko region, extending to the White Carpathians Mountains Protected Landscape Area (Czech Republic)....

ii Executive Summary The absence of a hierarchical approach to classification that integrates landscape and riverine ecological theory hampers scientific and regulatory endeavors to define natural resource management strategies protective of watershed dynamics. It is my intent to review existing aquatic and landscape classification methodologies and measures of ecosystem condition and to develo...

Landscape approaches have been identified as a way to address conservation and development issues in biodiversityrich tropical areas. The author conducted a literature review of 51 case studies selected by an independent analyst to evaluate how these approaches have been applied. The case studies are categorized and assessed against their objectives, scales and methods. The review highlights im...

The paper presents an example of the application of the landscape functions and natural potentials methodology to the environmental assessment in the upland area of Pradnik and Dlubnia rivers catchments, south Poland. The aim of the research was to propose evaluation methodology applied in GIS environment and based on available digital (or easy for digitalization) spatial data. The study proved...

Carbon stock estimates based on land cover type are critical for informing climate change assessment and landscape management, but field and theoretical evidence indicates that forest fragmentation reduces the amount of carbon stored at forest edges. Here, using remotely sensed pantropical biomass and land cover data sets, we estimate that biomass within the first 500 m of the forest edge is on...

The combination of remote imagery data, geographic information systems software, and landscape ecology theory provides a unique basis for monitoring and assessing large-scale ecological systems. The unique feature of the work has been the need to develop and interpret quantitative measures of spatial pattern—the landscape indices. This article reviews what is known about the statistical propert...
