Thus, alternative corridors with similar probability of use by fauna and without bottlenecks can be obtained by iteratively running GAC and NCE models. Effects of habitat fragmentation on biodiversity. First, the analysis of 22 Informative Studies on road planning revealed that the methods applied by practitioners for assessing the TCC were not sufficiently standardized due to the lack of uniformity in the cartographic information sources and the TCC valuation methodologies, especially in the analysis of the aesthetic and ecological quality of the landscape.

Estimating landscape resistance to movement: A case study in central Spain 4. A review of case studies. Intermountain Journal of Sciences, 5 Gontier M, Balfors B. The consistency ratio was also calculated to verify the values had been assigned consistently in the pairwise comparison.

This distortion is known as the stair step effect. A terrain ruggedness index that quantifies topographic heterogeneity. A proposal to improve ecological compensation paxcual in ocnstruccion and railway projects in Spain.

In athe fuzzy values refer to distances x from boundary of conditioning element outward. An equilibrium theory of insular zoogeography. Libro Verde de la Dehesa, 1— This analysis is known as model-impact aptitude.

Get to Know Us. This process reclassifies the range of values of the Coij raster into different intervals. Integration of GIS-based suitability analysis and multicriteria evaluation in a spatial decision support system for route selection.


Fuzzy land element classification from DTMs based on geometry and terrain position.

The environmental urbam were measured mainly through quality of biotope and landscape using different quality variables and indicators. La Espina – Canero 30 Company 12 Asturias 10Using this research as a base, iii each factor selected to build the matrix was assigned a resistance value and weighted and combined with the rest of the factors using the analytic hierarchy process AHP and fuzzy logic operators as multicriteria assessment MCA methods.

Ecological Indicators, 9 5— The inclusion of these variables in the partial synthesis of physical constraints is useful in the case of roads located in mountain ranges in certain regions. Conditional element to Roe deer behaviour Direction of effect relate to friction Habitat patches 1 Reduce Water sources Reduce Distance threshold values according to bibliographic sources meters Max Min Saura et al.

Tramo Burgos-Miranda de Ebro; Treatment of biodiversity issues in impact assessment of electricity power transmission lines: In Spain, feasibility studies for new roads and motorways are associated to a phase of the decision procedure which corresponds with the one known as the Informative Study, which establishes the physical, environmental, land-use and cultural constraints to be considered in the early stages of defining road cojstruccion layouts.

Landscape Research, 33 189— Ecological Indicators, 7 2— Landscape and Urban Planning, 155— Pero no siempre es posible definir el trazado de forma paralela a las curvas de nivel.


Although other authors have used similar categories see Acevedo et al. Is landscape quality inherent in the landscape or in the eye of the beholder?

In response to the first challenge ch1several authors have proposed methods to define the reclassifying threshold value Beier et al. Geographical Information and Planning. A case study eztructuras minimize environmental damage, building costs and travel time. These variables were grouped into physical, environmental, land-use and cultural constraints for the purpose of comparing the TCC values assigned to each dd in the various studies reviewed. Landsc Ecol 25 4: An Interdisciplinary approach to methods.


This doctoral thesis proposes new methodologies that improve the assessment of the visual and ecological landscape character using indicators and GIS models to obtain road layout alternatives with a lower impact on the landscape. This planning process follows a very precise procedure, with specific management tasks and technical instructions to be considered throughout its course, as indicated in the brotona for drafting Road Studies.

Moreover, this factor was not included in the EIA assessment when the study area was defined as critical for the survival of the species Astragalus oxyglottis M. Landscape Ecology, 27 6 consfruccion, — An important shortcoming was located in the assessment of ID. A second issue is the selection of a proper gamma parameter value to aggregate fuzzy sets for each factor with a gamma operator. This modification was included as it was considered to be better adapted when the number of intervals associated to the shrub layer was increased and the shrub layer FCC intervals were adapted to Mediterranean forests see Table 4.
