CONSERVATION OF RAPTORS IN THE HULA VALLEY
The Hula Nature Reserve in the north of Israel has been designated as a
"Wetland of International Importance" by the Ramsar Convention. In the
1950s the Hula Valley, was drained for agricultural purposes and only a
small area was preserved as the Hula Nature Reserve. In 1992, in the wake
of surveys and reports which pinpointed the negative impacts of the
drainage project, part of the area was reflooded as part of a
rehabilitation effort. The Hula Valley, including the nature reserve and
the recently reflooded area, is one of the most important migrating and
wintering sites in the region for more than 200 species of birds including
five endangered species according to BirdLife International and the IUCN
List.
Recently, the Ramsar Small Grants Fund for Wetland Conservation and Wise
Use approved a financial grant to the Israel Ornithological Center of the
Society for the Protection of Nature for a research project on two of the
endangered raptor species that winter in the Hula Valley: the Imperial
Eagle (Aquila heliaca) and the Spotted Eagle (Aquila clanga). The two
species are dependent on the agricultural areas in the Hula Valley which
suffer from a proliferation of rodents due to the peat soils created by
the drying of the wetlands in the mid-1950s. On the other hand, pesticides
are widely used in the area in order to control the agricultural damage
caused by the rodents. Therefore, the project aims to study, on the one
hand, the effects of pesticides and intensive agriculture on these two
species, and on the other hand, their contribution to preserving the
natural equilibrium of the Hula wetlands and surrounding agricultural
fields.
The main objective of the project is to promote the conservation of these
two target species and to preserve the wetlands themselves by:
* Studying the impact of intensive agriculture and tourism on the two
target species;
* Studying the ecological requirements of these two species in order to
develop a proper management plan for the entire area;
* Encouraging the cooperation of local farmers in protecting these
species and educating them as to the importance and advantage of these
raptors to the agricultural areas;
* Establishing an interactive education and conservation program for
local youth.
In order to fulfill these objectives, several methods will be undertaken.
Land surveys will be conducted to define the habitats used by the two
eagle species. Radio telemetry transmitters will be used to track the
movements of the species within the Hula wetlands and the surrounding
areas. Pellet contents will be studies in order to define the food
requirements of the species. Blood samples of six birds of each species
will be taken and analyzed in order to monitor the presence of pesticides
in the eagles' bodies.
An educational program will constitute an integral part of the project. As
part of the program, students will track the eagles marked with
transmitters as part of personal projects and will identify pellet content
and correlate the data with surveys conducted on local fauna. The students
will present the projects to the local community, thereby increasing
public awareness of conservation efforts in the Hula Valley. All relevant
stakeholders-including local farmers and decision makers-will thus be
involved in the project. In the future, a management plan will be
developed in cooperation with local authorities, landowners and developers
to improve the conservation of the two species and to help preserve this
unique wetland habitat.
