Comparing Conservation Value Maps and Mapping Methods in a Rural Landscape in Southern Finland

We tested to what extent conservation value maps are different if the valuation and mapping method is changed. We compared 66 different conservation value and 4 different ecosystem service maps. Using remote sensing and other georeferenced data, we produced 2 different habitat type maps, which were 50 % similar. We valued each mapped habitat type based on rarity corrected potential number of vascular …

The Landscape of the Dehesa in the Sierra Morena of Jaén (Spain) – the Transition from Traditional to New Land Uses

This paper tracks the evolution of the area covered by the dehesa in Sierra Morena from the mid 20th century to the present day, in an attempt to identify those areas in which traditional land uses still hold sway and others in which new land uses are appearing in relation to emerging business activities. These new uses have brought about an important transformation …

Swiss Tree Lines – a GIS-Based Approximation

Mountain timber lines are relevant in the context of land abandonment and climate change. For Switzerland, GIS-compliant delimitations of the tree line and the forest line are still lacking. Recent high-resolution landcover information offers new possibilities for GIS-based approaches. In a Swiss-wide study, an analysis based on slope zones was combined with a moving-window analysis to assess tree and forest …

Evaluating Anthropogenic Risk of Grassland and Forest Habitat Degradation using Land-Cover Data

The effects of landscape context on habitat quality are receiving increased attention in conservation biology. The objective of this research is to demonstrate a landscape-level approach to mapping and evaluating the anthropogenic risks of grassland and forest habitat degradation by examining habitat context as defined by intensive anthropogenic land uses at multiple spatial scales. A landscape mosaic model classifies a …

Effects of topography and surface roughness in analyses of landscape structure – A proposal to modify the existing set of landscape metrics

Topography and relief variability play a key role in ecosystem functioning and structuring. However, the most commonly used concept to relate pattern to process in landscape ecology, the so-called patch-corridor-matrix model, perceives the landscape as a planimetric surface. As a consequence, landscape metrics, used as numerical descriptors of the spatial arrangement of landscape mosaics, generally do not allow for the …

Statistical Classification of Terrestrial and Marine Ecosystems for Environmental Planning

Environmental planning is an instrument for the operationalisation of the precautionary principle in environmental law and, to this end, must rely on maps depicting the spatial patterns of ecological attributes ofaquatic and terrestrial ecosystems and of environmental change effects, respectively. In this context, different mapping techniques are presented by example of three case studies covering terrestrial, coastal and marine environments. …
