Bamboo for construction...a timber resource

In many developing countries, bamboo is traditionally considered as the poor man's material. This is obviously due to the abundance of bamboo forests and the relative low level machinery and expertise required to obtain a useable building material in its natural form (ie. round poles). It is used for everything from house framing, flooring, thatch cladding for walls and ceiling, and even as shingles for the roof.

Harvested bamboo timber (stacked for drying)

However, in many other countries where bamboo has not traditionally been used in the past, bamboo timber is starting to establish itself as a more exclusive building material into a niche upperclass market. The superior strength and durability of bamboo has earned its successful use as a timber for flooring and bench tops. These applications are utilising the more processed bamboo timber (ie. laminated strips of bamboo) but bamboo timber even in its natural form (round poles) are in high demand as people are wanting to use it more and more for construction of gazebos, fences, screens, etc.

The strengh and hardness of bamboo timber is equivalant to hardwood timber whilst the cost is also comparable to hardwood timber. So why then should people be considering growing bamboo on a commercial level? The simple answer is that it has the potential to be a direct substitute for hardwood timber and thus reducing the pressure on natural hardwood forests (our rainforests!).

Bamboo shoots for eating

Bamboo shoot production does not need to be on commercial scale, in fact it is also a great small crop for the common gardener - even on small suburban blocks. By choosing species which suit your garden (ie. ornamental or screening varieties) that also produce good shoots (or timber), you can combine a multitude of uses in the one clump of bamboo. A very versatile plant to have at your disposal.

Most bamboo species produce edible shoots - though some species produce naturally sweet shoots whilst others tend to be fairly bitter tasting. For clumping species which produce good edible shoots, please refer to the species descriptions in the Catalogue.

Enviromental Restoration

Bamboo is a pioneering plant in that it can be grown in full sun and tolerates high winds. This enables its use as a starting point in restoring cleared land which may have been damaged by overgrazing or poor farming. Because of the bamboos fast growth and dense foliage, it will quickly deposit a thick layer of leaf litter covering the ground, which will then start restoring degraded soils and re-establishing a cooler microclimate.

Bamboo for erosion control, windbreaks and noise barriers

Bambusa Oldhamii windbreak (15m tall)

A bamboos root system grows into a dense 'mat' of fine roots which is shallow but wide spread. This means that its ability to hold soil together is excellent, even in areas where erosion caused by flowing water is a problem. It will hold soil together along fragile river banks, deforested areas, dam walls and spillways. There are no tap roots on bamboo plants, thus they are not going to cause any problems if planted on dam walls (like so many other trees will).

Many clumping bamboo species have very erect (straight) growth whilst still tight clumping and bushy. These species are ideal for use as windbreaks around orchards, sugar cane fields, etc. There are bamboos that will grow very uniformly to whatever height is desired. So whether it be a short hedge (so that crops aren't shaded) or a tall barrier (to prevent storm damage from high winds), there is a bamboo to suit.

Waste water treatment

Bamboo has the capacity for very high nitrogen uptake. This makes it ideal for mitigation of waste water pollution and disposal of effluents. Waste water from manufacturing, livestock farming and sewerage treatment plants can be used to irrigate bamboo crops, thus converting the waste water into useful biomass.

It can also be used to treat water run-off from agricultural land. Most farming adds soil nutrients to waterways from pastures and cultivated fields. This water clouds and poisons clean water. Planted alongside rivers, creeks and ditches and holding dams, bamboo can catch these excess nutrients in the runoff water thus preventing harmful runoff from entering nearby streams.
