Secil: Learning to value biodiversity


29 July, 2009


Case Study


  • Characterize the fauna community
  • Characterize and evaluate the occupation level of fauna in the recovered habitats and compare with natural habitats
  • Define measures to encourage colonization by fauna based on results.

Restoration activities

  • Description of the study area and selection of the sampling locations
  • Characterization and assessment of species distribution in the different sampling locations
  • Determination of the conservation value of each species and habitat
  • Ecological modeling.


Biology Department, University of Évora


The main results achieved in this study were: (i) number of species; (ii) definition of the priority species for conservation; (iii) comparison between number and priority of species in the different habitats; (iv) definition of the value for conservation for each habitat; (v) identification of the limiting factors that influence the abundance and diversity of species; (vi) definitions of measures to encourage the colonization of fauna.


This study is remarkable since it is located in a natural park involving five animal groups (bio-indicators, prey, important predators) and the assessment of their relation to management options for vegetation (age ofrevegetation, revegetation in terraces and in slopes) using ten sampling locations.

Lessons learned

The study demonstrated the real natural values and the different biophysical components of the territory to sustainably manage the recovered areas. The involvement of all stakeholders and specialized technicians (biologists and engineers) is a crucial step to promote sustainable management.
