Client: Insular Council of Tenerife (Spain)

Date: March – December 2017


The objective of this project is the identification and characterization of the Ecological Corridors Network of Tenerife Island. This network, formed by areas of high ecological connectivity, aims to improving the coherence of the Natura 2000 protected areas and the conservation of the island biodiversity.

In order to ensure the permeability of a heterogeneous and complex territory such as Tenerife island, a holistic and functional approach was applied to the connectivity analysis. This kind of analysis is based, not only on the structure, but also on the dynamics of landscape functioning at different scales.

The analysis was based on the territorial adequacy modeling for a series of flora and fauna target species, using GIS tools such as CorridorDesigner and Spatial Analyst by ArcSIG. These analyzes were complemented with an intense bibliographic review and field sampling to verify the actual adequacy of the identified corridors.

Corredores Ecológicos de Tenerife

The actions that we carried out, for the achievement of the mentioned objectives, were the following:

  1. Summary of the legal scope applicable to the project.
  2. Characterization of natural habitats and protected areas present in the island (fragmentation diagnosis).
  3. Development of a Habitat Adaptation Model based on a permeability analysis using a set of selected species with the support of a scientific council.
  4. Modeling of «patches» or connectivity nodes based on the previous model.
  5. Cost-distance analysis for the determination of ecological corridors (more than 300 analyzes carried out to detect corridors in 7 types of ecosystems).
  6. Analysis of the ecological connectivity of the wet ravines.
  7. Analysis of the points of tension of ecological corridors with communication and transport routes.
  8. Presentation of results in various conferences and seminars.
