EIA and Special Ecological Evaluation Study  for  wind-farm project  at southern Evia

Environmental impact assessment and Special Ecological Evaluation Study  for  wind-farm project  at southern Evia

Country: Greece

Region: Southern Evia Island
Client: R.F. Energy
Start date : 03/2011
Completion date : 08/2012
Duration of assignment : 17 months

Detailed Project Description:

  • Detailed data collection of the existing conditions in the region of Evia.
  • Investigation of environmental impacts on the project area and the wider region, both during the project’s construction, as well as during the operation of wind parks
  • A choice of the project’s site is proposed, aiming at the satisfaction of environmental criteria and at the minimization of potential environmental impacts
  • Evaluation of corrective measures for the abatement of potential environmental impacts and presentation of the suggested Environmental Terms
  • Habitat identification and classification according to the 92/43/EEC Directive within the study area.
  • Assessment of impacts on habitats and important flora species due to construction and maintenance of wind farm facilities.
  • Ornithological research in the area where wind farms are to be installed, within Special Protection Area (SPA) on the island of Evia.
  • Brief description of avifauna habitats in the study area.
  • Presentation of legislative framework pertaining to the ecological study and the methodology applied during field work for flora and fauna.
  • Data collection of nesting, resting and feeding sites of important bird species,  migrating corridors and habitat attributes attractive to birds, such as a cluster of trees, cliffs etc.
  • Clarification of habitat use patterns pertaining to migrating avifauna species and raptor species found in the study area.
  • Assessment of impacts on avifauna caused by the construction and operation of wind farms due to disturbance, displacement, habitat occupation, barrier effect and collision risks and on flora caused by vegetation clearing.
  • Highlighting wind turbines, which seem to be presenting high risks in regards to avifauna and providing a mitigating plan towards impacts on avifauna, such as Radar accoutrement installation, which will serve the detection of avifauna species in preselected group of wind turbines, as well as an avifauna monitoring program.
  • Highlighting locations where important flora species are present and proposed mitigation measures for their protection.

Description of actual services provided by Enveco within the assignment:


Our staff covered the issues related to all phases of the preparation of the project. In particular, the following tasks have been covered:


Task 1: Coordination of field work, aiming towards habitat and flora data collection in the study area.
Task 2: Primary data collection of avifauna during hibernation period, spring and autumn migration periods, as well as during reproduction period. Mapping of avifauna records and corridors of important avifauna species  within the study area and highlighting of nesting sites, in order to attain optimal project design
Task 3: Data elaboration and assessment of the study area’s ecological value.
Task 4: Highlighting and assessing important avifauna and flora species in the study area and assessment of project’s impacts on them
Task 5: Analysis of wind energy parks’ site choice and final decision, based on the target of minimizing negative environmental impacts on both the natural, as well as man-made environment.
Task 6: Evaluation of corrective measures for the abatement of potential environmental impacts and presentation of the suggested Environmental Terms
Task 7: Composition of a complete ESIA 
Task 8: Presentation of the Project’s Environmental and Social Impact Assessment at public consultation meetings during the phase of permit evaluation
