Habitats and species

Monitoring flora and fauna

Climate action Nature Biodiversity

Iberdrola group applies several measures to protect and restore areas that might be affected by its facilities in the main countries it operates in.

Iberdrola carries out monitoring of flora and fauna, depending on the needs of each project, especially of protected or vulnerable species, silvicultural treatments, forest restoration with native species, integration and landscaping, etc. depending on the needs of each project with the objective of protecting species and habitats or mitigating the damage caused to them.

These activities are performed throughout the life of the project, tailoring the actions according to the construction, operation and dismantling phases.


Biodiversity in compensated areas 

Iberdrola applies the mitigation hierarchy (avoid, minimize, correct and, as a last resort, offset) in its projects' environmental impact assessments. It avoids sites which are protected or which are valuable because of their biodiversity and minimizes any impact on the environment.

By means of its offsetting activities, it sets out to improve the state of conservation of the biodiversity of species and habitats in areas affected by the presence of group facilities. Actions to improve biodiversity are also carried out, as described in the biodiversity reports and in the environmental dimension in the Sustainability Report [PDF] External link, opens in new window..

Some of the habitats being offset are listed below, most of which are from projects that have been under way for several years and that have continued actively in 2020:

    General Services Reforestation of 3.3 hectares to offset the construction of the ground-level car park adjacent to the Iberdrola campus in San Agustín de Guadalix (Madrid) with tree and shrub species. A total of about 3,600 plants. Compensation ratio 2:1. Monitoring will be performed for 3 years. Forest Restoration.
    Hydroelectric power plants Release of almost 5,600 eels into the Júcar, Cabriel and Mijares rivers under the plan to restore the eel population in the rivers of the Valencian Community, this being the sixth of 10 years. Eel repopulation initiative.

Relocation and habitat of the species of Pimelia Canariensis.
    Photovoltaic projects As part of the Núñez de Balboa project, in coordination with the Directorate General for the Environment of the Regional Government of Extremadura, two Agro-Environmental Management Areas of 45 ha each and two reserve areas will be created for steppe birds in the vicinity of the project, each with 5 ha. Lease agreements were established with landowners in 2020. Recovery of farmland and creation of steppe bird reserves.

    Onshore wind farms Continuation of the Habitat Management and Monitoring Plan for 25 wind farms with a surface area of 9,049 ha, on which approximately 303,400 plants were planted and the maintenance work was performed for the preservation of the habitats that were created. As part of the habitat monitoring programme, plantings, plant growth and livestock damage are assessed and hydrological monitoring is performed, etc. Compensation of habitats.
    Offshore wind farms Restoration and landscaping of the project's onshore substation includes the planting of 30,000 trees. Sowing and tree and hedge planting began in 2020. The compensation ratio is 2:1. Habitat restoration and compensation.

    Onshore wind farms Continuation with the monitoring and maintenance of Habitat Mitigation Areas (HMAs) associated with the wind farms. The HMAs have 44, 92 and 18 acres, preserved through activities such as controlling invasive species, excluding grazing and annual monitoring to document the progress of the recovery. Improvement of adjacent habitats and protection of associated fauna.
    Mitigation bank paid to ensure 250 acres of forest habitat for the Indiana bat (Myotis sodalis). Creation of bat habitats.
    Restoration and monitoring of pastures of a 6.6 a construction area of the Trimont repowering project. The rest of the site will be stabilised in late 2020. Ground restoration.
    Baixo Iguazú Hydroelectric Power Station Restoration of 117 hectares occupied during the construction. 37 hectares were restored in 2020.

    Reciprocity Agreement to provide infrastructure, materials and equipment to inspect natural resources in the Iguazú National Park and its surrounding areas. The construction of the base for inspecting the park in the municipality of Capanema and the acquisition of vehicles concluded in 2020.
    Compensation to protect the Iguazú National Park.
    Baguari (hydroelectric) Reforestation of 1.77 km2 of Permanent Preservation Areas (PPP). In 2020, work was done to recover slopes, enrich 48.11 and plant 64.01 ha. All areas were fenced and monitored except for islands, creating corridors for use by animals. Improving adjacent habitats, enhancing the absorption capacity of the soil and reducing the risk of losses due to erosion.
    Corumbá (hydroelectric) Reforestation for the creation of the Permanent Preservation Areas (APPs). In 2020, there was soil preparation and planting on 148 hectares (approx. 246,000 plants). A total of 1,690 hectares have been reforested with 1,694,000 trees since 2018. Improvement in soil quality and a reduction in the erosion.

Protected or restored habitats

Iberdrola carries out a variety of actions to protect or restore the different habitats that surround or are affected by the group's facilities. These are actions that have continued actively in 2020 which are also included in the action plans.

  • Knowledge of the species living in the vicinity of the facilities is essential for preventing harming them, even more so if they are protected.

    Iberdrola identifies the threatened species included in the IUCN Red List(1) and in national and regional lists with habitats in the areas where it operates to prevent any impact. The company implements species monitoring programs and research projects at many of its facilities to learn more about their behavioral patterns and integrate this knowledge into its operations.

    The following table shows the number of IUCN Red List threatened species identified by Iberdrola's facilities, without suggesting any impact or threat from its activity.

    IUCN Red List Classification  No. species
    Critically endangered (CR) 15
    Endangered (EN) 46
    Vulnerable (VU) 75
    Near threatened (NT) 71
    Least concern (LC) 723
