World's largest walnut forest - Arslanbob Forest - is located in the mountains of Kyrgyzstan. Each year there are collected some 1,500 tons of walnuts thus making this forest the largest single source of these nuts in the world.


Walnuts (Juglans regia) grow in enormous area from Balkans to southwest China. Since the 17th century it has been introduced in America as well.

Walnut is valuable tree, well known thanks to its beautiful wood and exquisite nuts. This large tree is light demanding and needs full sun and rich soil.

There is not much undergrowth under the tree - its leaves contain juglone, a natural herbicide. As a result groves of walnut are similar to shaded parks.

Walnut is considered to be one of the most valuable temperate hardwoods but even more valuable are nuts. Nuts of this tree have very high quality, oil is richly flavored. Different parts of plant are used in medicine.

History of Arslanbob Forest

According to research data, world's largest walnut forest is not too old. Some 2,000 years ago here were growing other trees - junipers, birch trees, ashes. Enormous forest of walnuts appeared approximately 1,000 years ago.

According to local legends the origin of this forest is linked to Prophet Muhamed. His envoy was searching for paradise on Earth and found one at present-day Arslanbob. This was beautiful valley with crystal-clear stream. Only trees were missing. Thus prophet sent to him a bag of seeds of fruit trees including walnuts. Envoy planted the seeds and tended the garden for many years.

Another story goes further into the past: according to this story the walnut forest was here already in the times of Alexander the Great (the 4th century BC) and Alexander brought a sack of walnuts back, to Greece, thus introducing this tree in Europe.

Research shows that the area of groves in the past was 630,900 ha (now - some 11,000 ha). Overexploitation, especially grazing has led to decrease of forest area.

In 1945 here was organized forest research station with an aim to establish commercial plantations and to increase yields.

Arslanbob Forest today

This unique forest - orchard grows on the south-facing slopes of Fergana range's, at the height of some 1,500 - 2,000 m. Down in the valley is located the small town of Arslanbob which in many ways depends on this forest. Not too far is located another large walnut forest - Dashman Forest Reserve.

Trees in Arslanbob forest grow up to 150 - 200 years old creating an impressive fairy-tale landscape of an endless, shady orchard. This forest is divided among the families of local people. In every time of the year this is an impressive, interesting place to visit. Here are found natural and man-made landmarks, such as several impressive waterfalls (two best known falls are 80 m and 23 m tall), sacred caves.

Of course, most interesting time is autumn when trees bring fruits. Every year at the mid-September - mid-October all locals get involved in nut collection. Many people stay to live in the forest during this month. Locals recognize that this is the best time of the year when family spends time together, meets with relatives and makes new friends. This is time of festivity and there are many lights in the forest with merry people who spend the long evenings in common feasts.

Walnuts are not the only value in this forest. Here grow many species of valuable fruit-bearing trees, such as specific species of apple (Malus siversiana), pear (Pyrus korshinsky), plum (Prunus sogdiana). Locals eat and collect thousands of tons of apples, pistachios, cherry plums and other fruits.
