IBERDROLA AND BIODIVERSITY
We protect ecosystem biodiversity as a source of sustainable development
Iberdrola group is committed to encouraging ecosystem biodiversity by establishing new and sustainable projects in a way that fosters harmonious coexistence and conserves, protects and promotes the development and growth of natural heritage.
Fostering economic and social development, respect for the environment and promoting biodiversity are Iberdrola's priority corporate values, and the company fully complies with Sustainable Development Goals thirteen and fifteen. Iberdrola Group manifests its commitment to safeguarding and promoting the biodiversity of ecosystems through concrete actions. The following are some examples:
- Integrating biodiversity conservation into the Group's strategy and in decisions on infrastructure projects.
- Integrating biodiversity into the Group's environmental management systems (EMS).
- Participating in research, conservation, education and awareness projects.
- Protecting species and habitats, avoiding placing new infrastructures in protected areas or those rich in biodiversity.
INITIATIVES, PROJECTS AND ACTIONS
By signing this Pact, Iberdrola underlines its commitment to biodiversity conservation and sustainable use. The Pact is sponsored by the Spanish Business and Biodiversity Initiative, created by the Ministry of Agriculture, Food and Environment (Magrama) and the Biodiversity Foundation, of which Iberdrola is also a member.
This ambitious project, developed since 2011 by Fundación Iberdrola España in conjunction with SEO/BirdLife, is a result of Iberdrola's commitment to achieving bird-friendly energy.
The program aims to preserve Spanish birdlife by expanding knowledge of migratory and bird breeding habits through the latest geolocation and remote-monitoring technologies. Different species have been equipped with GPS devices to gather the details about its migratory trips, the duration, what route they follow, at what speed and altitude they fly, where they rest and feed or if the routes are the same year after year, which make it possible for us to record all of their movements and show them in www.migraciondeaves.org. In addition, they help us anticipate any possible threats that could endanger them, while providing fundamental information to prepare relevant scientific studies.
SEO/BirdLife and the group for the Rehabilitation of Autochthonous Fauna and its Habitat (GREFA) have marked more than 80 lesser kestrels across Spain, enabling Spanish specialists to track their every move, their migratory paths, their African wintering areas and their location in real time in full detail for the first time.
Nano-GPS systems have been used to track the birds. These state-of-the-art devices weighing less than five grams are attached to the kestrel's back like a sort of backpack to reveal their movements day and night and monitor their migratory habits. This system has been used to mark 13 lesser kestrels in Cordoba, nine in Cuenca, 12 in Gerona, nine in Huesca, five in Jaen, 29 in Madrid and nine in Zamora.

In the same way, on the occasion of the 2018 World Migratory Bird Day, the Spanish Ornithological Society (SEO/BirdLife) has tagged four peregrine falcon (Falco peregrinus) chicks, a species listed as Vulnerable in the Community of Madrid Catalogue of Threatened Species. The tagging, which was made possible through cooperation with Iberdrola, will provide greater knowledge of this species, which is recorded as having at least 38 pairs in the region, of which 23 are in the mountains, three on the plain and 12 in the centre of Madrid.
This organisation has been monitoring the peregrine falcon population of Madrid for many years. In 2007 a pair was spotted at the General Gómez Ulla Hospital and after a nesting box was placed there to encourage them to reproduce it was occupied by a pair of birds. Since then peregrine falcons have been breeding here.

SEO/BirdLife has also presented the publication titled Migración y Ecología Espacial de las Poblaciones Españolas de Pardela Cenicienta (Migration and spatial ecology of the Spanish populations of the Cory's Shearwater), the third monograph in the Migra program edited by SEO/BirdLife in partnership with Iberdrola. The work was possible thanks to the banding of 460 examples across 13 breeding colonies throughout different Spanish regions, namely the Balearic Islands, Castellón, Murcia, Almería, Chafarinas Islands, the Atlantic Islands of Galicia and several of the Canary Islands. Given the magnitude of the registered positioning database, with its 1,017,029 tracked locations, considering not only the number of individuals but also the number and distribution of included colonies, in addition to the number of years of the study, this work is by far the most ambitious to date in addressing the movement ecology of Spanish species using next-generation remote tracking devices.

Another publication in SEO/BirdLife's MIGRA Program was the Migration and spatial ecology of the Spanish population of booted eagle. To carry out the study, 21 eagles have been tagged with GPS and more than 83,000 locations have been obtained that have guided us through the more than 194,000 km covered by the birds in their journeys. The study data reveals that international cooperation is essential to create safe areas for booted eagles on their migratory journeys to sub-Saharan Africa: during their autumnal migration, the booted eagles travel between 2,400 and 3,400 km, arriving in Savannah areas of the African Sahel. This trip lasts about three weeks and there are days that they fly up to 400 km at a maximum speed of 72 km/h.

During the six years of the program, a total of 856 birds from 32 different species have been marked and in 2018 a total of 17 markings are planned. Another relevant initiative of the Iberdrola Spain Foundation is the signing of a partnership agreement with the Bearded Vulture Conservation Foundation for a new project to study the influence of climate change on this and other Alpine birds.
Some of the latest findings of the program include the case of the swift, the summer migratory bird par excellence, which can travel 20,000 kilometres on its migratory flight to Africa. The common swift is one of the birds that best represents our towns and cities during spring. During the month of March, thousands of birds flood the sky every year with their characteristic screeching sounds and they abandon their nests during the end of July to migrate to Africa. 41 swifts of Nuevo Baztán (municipality of Madrid) were banded for this study.

Another example is the Spanish pallid swift. Through the use of GPS devices, now we can learn about its migratory habits and overwintering areas. In particular, we attached an emitter weighing 0.6 grams to a bird of this species in 2015, which revealed the secrets of its journey: 3,600 km, from Zaragoza to Benin and Nigeria, where it would spend the winter.

Another case is the white stork; after several years studying its migration (more than 50 specimens have been tagged with a GPS device), SEO/BirdLife experts have observed a change in the behaviour of this protected species: the growth of peri-urban dumps has changed their migration patterns and there are more and more storks that remain on the peninsula all year round due to the easy access to food from the dumps.

Furthermore, the MIGRA program by SEO/Birdlife has published a monograph on the Audouin's gull, a species native to the Mediterranean with a relatively small population, 90% of which nest in Spain during their reproductive season.
For the study on Migración y ecología espacial de la gaviota de Audouin en el Mediterráneo occidental y noroeste africano, 221,931 spatial locations of more than 15,500 different specimens were analysed. Its 100 pages contain the movements, phenology and spatial ecology of the Audouin's gull at breeding grounds, on migratory routes and in wintering areas. The study likewise reveals 15 areas of great value for the species on the African coasts that deserve to be identified as Important Bird Areas (IBA).
The programme for the conservation of this autochthonous and emblematic species in danger of extinction in the Cantabrian Mountain Range has involved active work between 2010 and 2016 with the two-fold objective of halting its decline and fostering its recovery.
At the start of the project, it was estimated that there were only some 400 specimens between Asturias, León and Cantabria. To contribute to the recovery of this species, the European LIFE+ Cantabrian Capercaillie Project, coordinated by the Biodiversity Foundation of the Ministry of Agriculture and Fishing, Food and the Environment, with the support of Fundación Iberdrola España and the Autonomous National Parks Organisation, a series of urgent conservation, social participation, awareness raising and dissemination actions have been carried out.
Some of the main actions carried out since 2010 include:
- Forestry treatments in over 500 hectares to improve the Capercaillie's habitat.
- Removal or signage of 60 km of dangerous fences to eliminate the risk of electric shock.
- Control and monitoring of the deer population, as a result of its direct effect on the availability of food to the Capercaillie.
- Breeding in captivity programme as a complementary measure to the management of the habitat and re-introduction of Capercaillies in wildlife environments.
- 19 land custody projects thanks to 29 voluntary agreements between owners, non-profit organisations and other public and private agents.
- Environmental awareness raising and education actions, with workshops at schools, in which 2,000 students have participated.
This project has laid the foundations for the future conservation of the species, according to the experience and technical expertise acquired during the execution of the different actions.
Iberdrola has been implementing biodiversity programs and plans for years, the management of which is ongoing. As well as assessing environmental impact, these initiatives also aim to prevent and/or mitigate it, restore natural capital, develop relations with stakeholders and raise awareness amongst society. The Group's work in Spain, the UK, U.S., Brazil and Mexico can be viewed in the Action plans section.
