Recycling a Dump for Half-a-Billion Birds

Swooping down from the granite Eilat Mountains, the tightly packed swarm
glided over the neon lights of the city, headed east towards the palmeries
along the Israeli-Jordanian border. From a distance, the horde looked
like a pack of angry hornets casting about for prey. But this throng—several
thousand strong—was comprised of one of the few species of Accipitridae
known to migrate gregariously. Levant sparrowhawks were arriving at their
traditional spring roost at Eilat, Israel.
Israel is the only land bridge for birds making their autumnal and spring
migrations between Europe and Asia and Africa. The Eilat region is especially
important because it is located on the northern edge of the Saharan-Arabian
desert belt and is reached after a continuous flight of almost 2,000
kilometers over the Sahel, Sahara, and Sinai Deserts. It is estimated
that over 500 million birds, representing 230 species, pass through this
area annually. In many cases, the majority of the world’s population
for a given species, such as steppe eagle or Levant sparrowhawk, concentrate
at this regional bottleneck. Soaring migrants especially avail themselves
of the Eilat staging area—an estimated 5 million birds.
Eilat was once an extensive salt marsh of 12 square kilometers located
at the terminus of the surrounding valleys, which flooded during the
winter. Its soil was high in salt content, and its surface covered by
clay, dictating a unique plant community dominated by Suaeda monoica.
This species flowers and develops fruit in spring and autumn, a perfect
food plant for migratory birds. Today, the marsh is gone. . .completely.
. .lost to human occupation.
In 1948, the City of Eilat was established on the western side of the
Gulf of Aqaba. The human population has risen steadily through the years,
reaching 53,000. Hotel construction brought economic growth to the city,
with some 13,000 rooms available to vacationers. Most of the hotels’ footprints
and artificial lagoons were carved out of the salt marsh. Other large
areas were converted to agricultural fields, while still other areas
were transformed into salt or algae pans for commercial harvest of these
resources.
The disappearance of indigenous birds from the region—rufous bush
robin, Dead Sea sparrow, and northern shrike—reflect the state
of the habitat’s deterioration. However, the implications of the
marsh’s demise go far beyond its effect on local populations. Small-bodied
migratory birds are especially vulnerable, because they can only load
on enough fat in Africa to sustain them through their crossing of the
hostile deserts. They have always depended upon the salt marsh to provide
the sustenance needed to continue their journey north to the breeding
grounds.
Migrants usually reach the Eilat area after having flown for 20 to 40
hours without “refueling.”
The conservation of staging areas is of the utmost importance for migratory
birds. This is especially true for Arctic breeding or trans-Saharan migrant
species for which the breeding period is very short and the nesting period
is critically timed. Failure to arrive on the breeding grounds in optimal
condition, or at the right time, may mean that nesting will not occur
or that death will result.
In 1993, foreseeing the imminent need, International Birding & Research
Center-Eilat acquired a garbage-dump site used from the 1950s to the
1970s. We have recycled the 64 hectares of “human-abused” landscape,
converting it into the environmentally friendly Eilat Bird Sanctuary.
Early in the project, all funds raised were applied to burying the garbage
in situ. We convinced local building contractors to pour clean earth
that had been excavated for new construction onto the dump. When soil
depth reached 3 meters, we planted the area with indigenous vegetation,
which is irrigated with partially treated sewage water. Owing to the
water’s high organic content, the plants have flourished.
We also constructed a freshwater lake. A Palo Alto, California, couple
donated the money used for the lake’s construction: the husband
presented his wife, an ardent birdwatcher, with a lake in her name for
her 60th birthday. Mekorot, the national company that desalinizes the
city’s water, donates excess salt-free water it generates to fill
Lake Anita. The lake serves millions of birds, and its outflow travels
an open canal to the Red Sea, providing 3 kilometers more of habitat.
While the area is less than 5 percent of the original marsh, the birds
now, at least, have a place to stage and feed. When the sanctuary is
completed, we will have substantially replaced the habitats lost, and
Eurasian migratory bird populations will be able to continue to swarm
here.
