Although other authors have used cojstruccion categories see Acevedo et al. Once cost resistance values are assigned, rescaled and weighted to selected factors, these must be grouped.

Ejemplo de desdoblamiento de calzadas para reducir el movimiento de tierras. Nederlandse Geografische Studies pp.

In this sense, our application of Atkinson et al proposed methodology has resolved the general lack of justification for choice of environmental variables and their thematic and spatial representation which it is one the most common knowledge gaps estimating landscape resistance to wildlife movements Zeller et al, Identification of landscapes for drafting Natura network Management Plans: There are also patches of scrublands as a result of the degradation of the forest, and some small towns and villages Acevedo et al.

In non-compensatory MCA techniques, the TCC level is established as being inversely proportional to the constraints defined, and the most restrictive scores are added to the global study map see Fig.


ABSTRACT The assessment of different alternatives in road-corridor planning must be based on a number of welldefined territorial variables that serve as decision making criteria, and this requires a high-quality preliminary environmental assessment study.

In addition, roe deer prefers areas that are farther away from urban areas and linear transport infrastructures Acevedo et al.

The main limitation of this tool is that it only enables the analysis of one path in a corridor composed by multiple paths. Hemos tenido tantas conversaciones y buenos ratos. Recent literature reviews on network analysis of landscape connectivity and measures include Baranyi et al.

In our case study, we selected 5 factors.


The impact of roads on landscape and corrective measures. GIS based multi-criteria mrtalicas to identify potential sites for new highway tracing layout according to landscape constraints. Landsc Eco 27 6: Introduction to Landscape Ecology.

Journal for Nature Conservation, 16 2— Three factors were selected: Buffer effect of proximity to transitional zones among patches.

Pulling effect of water resources and fresh pastures. En el caso de la curvatura PLANC, es posible conocer la curvatura predominante en la ladera de un trazado de una carretera que constrhccion siguiendo las curvas de nivel.

La longitud de corredor cortado y su importancia define el impacto causado. In order to make them comparable, TCC was re-scaled from 0 to see Table brotpnswhere 0 is the lowest level of restriction highest TCC for road construction and the highest level of restriction lowest TCC.


We compare the connectivity estimated with the brootons path with our proposed methodology, observing even absence of significant differences at global scale, but not to local scale in our study area.

Acceptable 2, Scoring variables for TCC assessment were detailed, but important variables were overlooked. The aim was to evaluate the quality of the methods applied and the homogeneity and suitability of the variables used for defining the TCC.

Public preferences for landscape features: The limitation of this approach is that the value of the resistance coefficients must be known for each ecological feature studied in order to reliably define the cost or resistance surface Folkeson et al.

Soil loss and displacement by heavy equipment in forest road subgrading projects.


Fragmented patches were considered connected and suitable for home ranges if forest patches were separated by less than meters criterion c4. Estado del Arte Otero, I.
