The
electrocution is the cause of 60 % of the deaths of Bonelli's Eagles
in Catalonia (adults and non-adults). For this reason studies
have been realized to detect the principal points of electrocution in
breeding and dispersal areas of Bonelli's Eagle in Catalonia.
Studies
in the nesting areas of Bonelli´s Eagle
More
than 20,000 electrical supports located in the sectors precoastal and
coastal of the province of Barcelona are cartografhied; they are
included in the natural parks of Sant Llorenç of the Munt - Serra de
l'Obac, Montseny and Garraf, in the Spaces of Natural Interest
(EIN) of Cingles de Bertí, Gallifa, l'Ordal and in the areas located
around all these protected natural spaces.
It
is determined that the correction of all the supports catalogued like
more dangerous, approximately a 5% of the total, would avoid 70% of the
electrocutions of birds that take place in this zone.
Study
financed by the Area of Natural Spaces of the Diputació de Barcelona.
Studies
in the dispersal areas of juveniles of Bonelli's Eagle
Collaboration
in a study to detect the principal points of electrocution existing in
the dispersal areas of the
juveniles of Bonelli's Eagle placed in the province of Lerida (IBA 142
and 144).
It
is determined the electrocution risk of more than 3,000 pylons placed in
a total area of 800 km2.
It
is stated that these natural areas of the province of Lerida are one of
the principal zones of Catalonia where the electrocution affects more
seriously a great number of birds, principally juveniles of several
species of birds of prey.
Work
financed by the Servei de Protecció de la Natura of the Departament de Medi Ambient of
the Generalitat de Catalunya and
the Fundació Miquel Torres.
Application
of anti-electrocution measures
1.
Signature of a pioneering agreement of collaboration in Catalonia
involving the company FECSA-ENDESA, the Diputació de Barcelona
and the Universitat de Barcelona, for the detection and later
correction of the electric pylons that bear a major risk of
electrocution for the birds present in the province of Barcelona.
The
Departament de Biologia Animal of the Universitat de
Barcelona advises the technicians of FECSA-ENDESA in the tasks of
correction of the dangerous electricity pylons, and develops the new
studies for the location of power lines dangerous for the birds.
The
company FECSA-ENDESA realizes the corrections agreed with the
researchers of the University of Barcelona, and assumes the economic
expenses derived from the application of these measures. The
Àrea d'Espais Naturals of the Diputació de Barcelona watches
over the correct application of the work plan and finances new studies
for the location
of electrocution points for
birds within the territorial limits of the open spaces that it manages.
In
the framework of this agreement there have been corrected 450 dangerous
pylons placed in the Nature Reserve of Sant Llorenç del Munt – l´Obac
and outskirts (province of Barcelona), in an area where three adult
specimen of Bonelli´s Eagle had been found electrocuted.
In
the later monitorings of the corrected supports any bird species has
been found electrocuted.
2.
Signature of an agreement of collaboration with the company ELECTRA
CALDENSE S.A. from Caldes de Montbui (province of Barcelona) and the
Diputació de Barcelona, to locate
and to correct the dangerous pylons present in the power lines of
distribution of its property, which are included in two territories of Bonelli's Eagle.
3.
Signature of an agreement of collaboration with the company
ESTABANELL Y PAHISA ENERGIA SA of Granollers (province of Barcelona) and
the Diputació de Barcelona, to locate and to correct the present
dangerous pylons in the power lines of distribution of its property in a
territory of Bonelli's eagle.
