contour terraces, is a renewable and sustainable resource, which
can be provided to the planted sites even during droughts. Terraces
are up to 0.7 metres high and the distance between terraces ranges
from 8 to 25 metres. Excess runoff water flows through a spillway
system, avoiding erosion damage during extreme rain and flood
events. Trees and pasture are developed along the terrace.
In areas with rainfall below 100 mm, trees are planted in limans
(ponds) constructed in wadis and valleys. Limans are dammed sites,
into which floodwater flows to the planted trees. The area of limans
usually ranges from 0.2 to 0.6 ha and is supplied by watersheds
10-100 times as large. They can be used for recreation, fuel or shade.
Implementing water harvesting methods and afforestation on a
watershed scale provides a means for flood and erosion control.
Controlled grazing reduces fire hazard and provides additional
runoff for planted trees. Soil-conservation measures, such as gully
head and bank control and proper drainage of cultivated areas, are
major components in the rehabilitation effort.
Natural forests in Israel
Nearly one third of the forests in Israel are unplanted ‘natural forests’.
They are mostly composed of Mediterranean vegetation, similar to the
Californian maquis or chaparral. In protected sites, there are large trees
of the same species that grow in the maquis areas. This indicates that
maquis formation is the outcome of centuries of overcutting, overgraz-
ing and fires. Natural forests are mainly located in the mountain regions
in the central and northern regions of Israel and cover about 40,000 ha.
The main tree species in the maquis areas are oaks (
Quercus calliprinus
,
Quercus boissieri
and
Quercus ithaburensis
),
Pinus halepensis
,
Ceratonia
siliqua
,
Pistacia palestina
and
Cercis siliquestru

Ecosystem goods and services from planted forests
Israeli forests, both planted and natural, are multifunctional, ecological
landscape systems, which are managed for multiple services to the public
and ecology of their surrounding regions. The primary goal
of KKL is to protect the planted and natural forest resources
and maintain quality forested environments.
Timber production
In Israel, forests are not planted for timber production,
but there has been some wood production as a result
of forest management (thinning, sanitation operations
and clear cutting after fires). The timber serves mostly
for firewood and some industrial uses. As a result of
the rising cost of fuel and other energy resources, the
demand for firewood has increased significantly. In the
last five years, a programme has been run in rural areas
to provide families with free firewood from the forests.
Non-wood/timber products such as mushrooms, fruits
and herbs are also collected on a small scale.
Grazing pasture
Most of the forests in rural areas are used for grazing,
mainly for cattle, but sometimes for sheep and goats. In
open spaces, special groves are being planted to provide
shade for animals as well as for honey production.
Recreation and tourism
KKL provides recreation and tourist services, park infra-
structure and sustainable development for the more
than 12 million people who visit the forests every year.
Thousands of picnic sites, scenic roads, observation
points, hiking and biking trails, playgrounds, natural parks
and historic sites have been developed or reconstructed,
all open to the public free of charge. KKL has initiated
‘e-yarok’, a green newsletter that offers information on
activities, field trips and cultural activities in the forests.
The oases and wadis are home to groves of trees that provide welcome shade to people and animals
