Monitoring flora and fauna

Iberdrola takes various actions to prevent or restore areas that may be affected by its facilities in the principal countries in which it operates.

In order to protect species and habitats or mitigate damage over themselves, and based on the needs of each project, Iberdrola performs monitoring of flora and fauna (especially protected or vulnerable species), forest treatments, forestry restoration with indigenous plants, landscape integration and accommodation, etc.

These activities are carried out over the entire life cycle of the project, adapting the actions to be taken during the construction, operation, and decommissioning phases.



Prior to the construction of new facilities, environmental studies are conducted to collect environment characteristics and possible impacts thereon, with the subsequent implementation of the required corrective measures identified in the various environmental studies. Offset areas are intended to improve conservation status and the biodiversity of species and habitats with respect to the areas affected by the presence of the Group's facilities. In addition, various activities are performed to improve biodiversity, as described in the Biodiversity Reports and in indicator G4-EU13 of the Sustainability Report.

Below are some of the habitats that are being offset, the majority of the projects already commenced and being continued during 2016:

  • United Kingdom

Iberdrola carries out different actions, with the purpose of protecting or restoring the different habitats in its environment or those affected by the installations and facilities of the group. These are generic actions, which are still active in 2016 are also included in the action plans. Some of the most important actions are described below:

  • Spain

    • During the construction in recent years of two significant hydroelectric projects, La Muela II and the expansion of San Esteban, an Environmental Monitoring Plan has been implemented at each facility. This includes various actions, such as, for example, at la Muela II, a vegetation and forestry restoration of affected areas with indigenous plants; restoration and recovery of an old quarry and rubbish dump, etc monitoring of the loss of habitat and fauna, etc. There has been continued implementation of the Improvement Plan (Plan Mejora) biodiversity project, which includes the dismantling of abandoned structures and buildings and the subsequent restoration of the environment.
    • In 2016, 44 environmental actions were implemented in Spain before and during the construction of electrical substations and lines. Advance studies performed deal with the affect on the Nature 2000 Network, flora and vegetation, nesting by birds of prey, landscape integration and accommodation, etc. During construction, land was restored and prepared, vegetation and birds were protected, invasive species were controlled, etc.


  • United Kingdom

    • ScottishPower continues with Biodiversity Action Plans at each facility to recover and promote the regeneration of the natural habitats, fauna, and flora characteristic of the environment of the facilities. More information is available at www.spenergywholesale.com.
    • ScottishPower Renewables continues restoring habitats included in the Habitat management plans implemented in wind farms.


  • United States

    • Avangrid Renewables continued in 2016 developing plans for managing and monitoring habitat at the wind farms Manzana, Big Horn, Barton Chapel, Barton, Blue Creek, Buffalo Ridge I MinnDakota, Dry Lakes I/II, Groton, Hardscrabble, Juniper Canyon, Klondike III/IIIa ,Leaning Juniper II, South Chestnut among others with good results. In addition, there is work underway to eliminate an invasive herbaceous species at Klondike II and work is continuing on the restoration of wetlands near the Hoosack wind farm. In Blue Creek wind farm, additional plantings have been made in those areas where restoration wasn't satisfactory.


  • Brazil

    • At the affiliated Brazilian hydroelectric plants, there has been a continuation of programmes for the recovery and offset of Permanent Conservation Areas (APPs) and degraded areas (quarries, dumps), mainly through reforestation. Various environmental programmes for conserving biodiversity are also performed annually based on the impacts caused by their operation: monitoring fauna (icthyofauna, herpetofauna, mastofauna, avifauna, entomofauna, etc.), monitoring flora in reforested areas, monitoring water quality, monitoring erosive processes, etc.
  • Mexico

    • Iberdrola Mexico participates in an ambitious project for the recovery of the Estero Garrapatas swamp, with the collaboration of the Autonomous University of Tamaulipas and the port authorities of Altamira. The swamp was affected by the reduction in the water supply after the construction of a gas pipeline and the Company has been actively participating in the restoration and recovery of the ecosystem since 2002. See the awarded video.

    • In Mexico, are important activities in the La Ventosa wind farm, which has tracked the reforestation carried out during construction and wind farm La Venta III that have taken steps to implement the reforestation of an area of 19 has. In addition, the line La Venta III is in process to run reforest an area of 25.56 ha.
  • Other countries

    • In the wind farms of the Group, where has been necessary recover land affected by construction activities, performing revegetation and silvicultural treatments among other actions have been developed.
