Bamboo Propagation Methods-KEFRI Case
Study
Introduction.
Most of the bamboo resources in Kenya comprise one indigenous
species, Yushania
alpina, which was formerly known as Arundinaria
alpina.
According to a KEFRI senior scientist and bamboo expert
Mr. Gordon
Sigu, this species, which is commonly known as alpine
bamboo, occurs naturally on the main mountains and highland ranges
of Kenya and Eastern Africa.

The species is currently estimated to cover about 150,000 ha, located mainly at altitudes ranging from 2400 to 3400 meters above sea level. It
thrives in the Aberdares ranges, Mt Elgon, Mt Kenya, Mau escarpment and Cheranganyi Hills. With the exception of a few clumps of the species
left on farms by farmers living around forest areas in the highlands, very little cultivation of this species on farm has been done
Among the most important minor forest products, bamboo has continued to gain recognition. Today it is considered as a multipurpose plant and
as a valuable timber substitute. In Kenya, bamboo is much sought after for use in horticultural flower farming, handicraft, residential fencing and
other minor cottage industry products like toothpicks, basket making and incense sticks.
From 1940 onward, hundreds of thousands of forest lands were cleared for conversion into agriculture. Unsustainable felling of forests also
resulted in the disappearance of vast areas of alpine bamboo. By 1980 over-harvesting of indigenous timber and bamboo forests was having a
detrimental environmental impact. Environmental strategies and conservation measures were urgently needed to deal with the situation.
In 1986, as an effort to curtail further destruction, the President issued a directive banning all cutting of indigenous bamboo. This was not followed
by the setting of clear and definite or specific guidelines that would have formed the procedural follow-up for the implementation of such
pronouncements. The ban on bamboo harvesting to date remains in place.
During the last twenty years, some research on species selection and investigations on their growth was done mainly by the Kenya Forestry
Research Institute (KEFRI) in collaboration with several Asian research and development institutions. This research work has introduced over
twenty Asian bamboo species into the country. Half of these are successfully growing in the field under various ecological conditions.
The introduced species are more versatile and can be cultivated in areas where the local bamboo does not thrive. Farmers, horticultural
flower farming companies, and Kenya Forest Service have expressed great interest in growing these bamboo species on their land, and
harmonized methods are being introduced to ensure that projected outputs are successfully realized.
Past Research and Development Activities.
Research and development (R&D) activities on bamboo have been ongoing at KEFRI since 1980s. Following the ban on bamboo harvesting
in 1986, KEFRI initiated a program to investigate the potential of bamboo and to develop strategies for its cultivation and utilization in Kenya.
Raising Bamboo Planting Materials.
Growing bamboo starts with obtaining the materials that may come in the form of seeds, wildings, offsets or cuttings gathered from forests.
Tissue-cultured plantlets provide other forms of planting materials. Such planting materials can be obtained and raised in a nursery.
