the year 2008, the Conservation Biology Team of the University of
Barcelona (EBCAP) has carried out a global valuation of the corrections
made in the last 7 years in a trial area of about 2,000 km2 located in
the pre-coastal sector of the province of Barcelona, that includes 3
territories of Bonelli’s eagle where several cases of electrocution of
adult individuals are known. In the previous studies made by the EBCAP
in this zone, they had been catalogued and calculated the electrocution
risk of 17,804 electrical pylons. This information allowed to
prioritize the correction works in those pylons with greater
electrocution risk for birds.
From November 2001, a total of 1,157 pylons that are property of 3
powerline companies that operate in the province (FECSA-ENDESA, Electra
Caldense S.A. y Estabanell y Pahisa Energia S.A.) were corrected. The
evaluation of all the corrections has allowed to establish which
measures are more effectives in the field. The results have stated that
the number of corrections made at the moment already has significally
reduced the cases of mortality by electrocution detected in the zone.
In addition, in the last 5 years any new case of electrocution of the
individuals of Bonelli’s eagle that breed in the territories included
in the work area has been registered. The positive results show the
necessity to finalize the correction works in the present area and also
to extend them to other zones of Catalonia important for the Bonelli’s
The accomplishment of this project has been possible thanks to the
collaboration agreements between the Diputació de Barcelona, the
University of Barcelona, the Fundación
Miguel Torres and the 3 electrical companies previously mentioned.
The preliminary results of the project were presented the day 3rd of
December in the II Course on electrical lines and protection of the
birds, organized by the Life project of Conservation and Managing of
the Bonelli’s eagle of the Dirección General de Patrimonio Natural y
Biodiversidad of the Community of Murcia.
