Introduction
Myanmar lies between longitudes 92° and 102°E, and 10° and 30°N latitudes. Myanmar has total land area of 676 577 km2, and 50% is covered with forest. There are more than 20 000 species of flowering plants in many forest types depending on localities. These types are: mangrooves, estuarine forests in the delta regions, deciduous forests along the middle mountain ranges (Bago Yoma), dipterocarp forests where there is pronounced dry season, evergreen forests prevail where there is good rainfall and moisture regime, hill evergreen and subalpine forests at high attitude and subtropical regions, dry thorny forests in places with very low rainfall. In Myanmar, there are six national parks, one near Yangon and others spread all over. In these parks there are bamboos growing naturally or some planted for aesthetic reasons.
Myanmar used to have a big Bambusetum with more than 20 species in Yangon on the then Rangoon University Campus and it was destroyed due to a new housing project. There is a small bambusetum with 11 species in the FRI Campus, Yezin. In Pyinmana there is a Botanical Garden with 5 bamboo species.
Distribution and other aspects
Bamboos usually grow mixed with other species and they form the understorey in high forests. An almost pure bamboo forest of Melocanna baccifera, is found in the Arakan Yoma crossing from Pathein and Pye into Rakhine State, mixed with other species like Dendrocalamus strictus, Bambusa longispiculata and Thyrsostachys oliveri scattered over the range. A pure bamboo break of Dendrocalamus giganteus used to exist in Myanaung area as reported by Gamble in his book A Manual of Indian Timber. Other Bamboo breaks of Bambusa bambos and B. tulda are found along stream banks and lower hill slopes.
Myanmar has 17 genera, about 100 species and 4 varieties of bamboo (See Appendix I and II). They range from small species, Arundinaria armata and A. racemosa, found on high mountains, to very large species like Dendrocalamus giganteus, D. brandisii and D. hamiltonii with culm length reaching over 35 m (105 ft) with diameter 25 cm (8-10 inches). Both monopodial and sympodial species are found in Myanmar. And many species are indigenous and a few are introduced from neighbouring countries.
The following species are commercially important.

Some species of the following genera are found on very high mountains: Arundinaria (4000 m), Bambusa (1600 m), Celphalostachyum (1600 m), Chimonobambusa (2000 m), Dendrocalamus (2000 m), Dinochloa (1600 m), and Klemachloa (2200 m). Distribution of Bamboos in various States and Divisions in Myanmar is given in Appendix III.
For aesthetic reasons many bamboos are cultivated, examples, Bambusa bambos (hedge plants with thorns), B. vulgaris (the yellow bamboo) (with longitudinal green stripes) and B. wamin (with its swollen internodes), also used for landscaping, house gardens, parks, zoological gardens, in and around big cities in Myanmar. Some bamboos such as Bambusa longispiculata, B. wamin and Thrysostachys regia are planted in many Buddhist Monastries, in the villages and gardens in urban areas for local sales.
Structure of bamboo forests: Some studies were made in 3 areas where a great quantity of bamboo was found growing. The areas are:
(1) Bago Yoma AreaThe species studied are Bambusa polymorpha and Cephalostachyum pergracile for areas (1) and (3) where they are abundant and Melocanna baccifera for area (2). The main objective of studies was for extraction of bamboo for paper mill. The species selected are abundantly growing in those areas and also because of their usefulnesss in making paper pulp. The studies included counting of number of culms per clump, number of clumps per area and the ages of clump. For M. baccifera the counting was done per unit area.a. Eastern part with bamboo area - 5969.95 km2(2) Rakhine Yoma Area
b. Western part with bamboo area - 2224.8 km2with bamboo area - 5059.27 km2(3) Tanintharyee Divisionwith bamboo area - 1872.57 km2
Average no. of culm/clump
(i) B. polymorpha = 10 to 13 culmsAverage no. of clump/acre
(ii) C. pergracile = 9 to 14 culms
(i) B. polymorpha = 30Ages of clump (average)
(ii) C. pergracile = 25 + others = 60 clumps
(i) B. polymorpha (1 yr = 3), (2 yr = 3) (3 yr & above = 7)Number of culms/acre
(ii) C. pergracile (1 yr = 3), (2 yr = 4) (3 yr & above 7)
Average ratio of the above spp is 1:1:3 or 1:1:2.
Melocanna baccifera = About 25 000 culmsFelling cycle for bamboos: Because of the different ages of culms contained within clump for B. polymorpha and C. pergracile and number of bamboo per unit area for M. baccifera, the following cycles are suggested by forest department.
25 000 culms/area means the distance between them approximately 1 ft 4 inches (45 cm).
(1) 7 to 15 year cycle - B. polymorpha and C. pergracileThe suggested felling cycles were calculated depending on amount of output of bamboo/ ton in certain areas.
(2) 3 to 5 year cycle - M. baccifera.
e.g.Flowering of bamboos: Flowering of bamboos of different species was observed but details very seldom recorded. The following are some records on bamboo flowering in Myanmar:Rakhine area - 112 000 tons (with 15 year cycle)
Tanintharyee - 42 998 tons (with 7 year cycle)
Taungoo - 13 392 tons (with 7 year cycle)

1. Offsets and Clump-divisionThe last method was developed in Forest Research Institute, Myanmar. The whole or part of the rhizomes dug up, separated into units and then each planted in plastic bag in the nursery for 2-3 months before the planting season. With the onset of rain they were planted out in the field. They were esay to transport as they were small and the cost was less.
2. Rhizome cuttings
3. Culm cuttings
4. Layering
5. Rhizome cutting of wild seedlings.
Propagation by seeds was practised whenever seeds were available. Seeds were collected, cleaned and sown in germination boxes and after germination they were transferred to plastic bags before outplanting in the field.
Tissue culture method is not yet used as trained persons are lacking and the method is very costly.
Plantations: There are abundant bamboos everywhere in Myanmar, therefore it is sometimes thought not necessary to have plantations. In villages when one is in need of bamboo, one goes into the forest nearby and gets it. Villagers know how to grow bamboo but never planned to have plantation. They grow in the house garden mostly for ornamental reasons or as a fence around the compound.
The villagers also know that once the bamboo flowers, it dies. They also know not to cut all the culms from a clump. They differentiate the bamboos as Wanu (young, one-year-old) Tanyin (middle, two-year old) and Wayint (mature, more than three-year old). Actually depletion of bamboos in nearby forest is mainly due to cutting for industrial purpose or taungyar (shifting cultivations) and not due to local use. Maybe in the near future, with the knowledge we gain through research, there will be plantations established.
Bamboo research: Research on bamboos before the last 2 decades was mainly concerned with utilization. Studies on low-cost roofing methods, different patterns of weaving, use of bamboos as walling materials, fence building, and their preservation methods were described (See Appendix IV). Raw material availability for paper mills was also studied. Many bamboo forest areas were aerial-photographed. Inventory of bamboos species in some localities was carried out.
As stated earlier, many people think that cultivation of bamboos is not necessary as there are abundant resources of bamboos. Only when Forest Research Institute (FRI) in Yezin was established, scientific study concerning bamboos was started. Before the founding of FRI Yezin many foresters studied bamboos mostly for utilization aspect. Some important references are mentioned (1-17). The following aspects were studied.
1. Use of bamboo shingles as low cost roofing materials.Future research work will concentrate on conservation and improvement and utilization research. A general survey on bamboos concerning species diversity also needs to be carried out.2. Studies on bamboo propagation.
3. Testing methods for propagation on a large scale.
4. Effects of tending operations on some plots of naturally regenerated bamboos.
5. Vegetative propagation of bamboo as raw material for paper mill.
6. A preliminary investigation on the production of bamboo boards.*(10)
7. Thinning of trial-planted bamboo clumps.*
8. Silica content of some important bamboos.*
9. Pulping on bleaching properties of Kayin-wa (Melocanna bambusoides)
10. Relationship between fiber morphology and pulp sheet properties of burmese bamboos. (14, 15)
* Note: They are ongoing research works.
Conservation and improvement: Commercially important species will be selected in the first place to determine their quality. Ex situ conservation will be carried out. The following bamboo species are selected for conservation and improvement work.
1. Bambusa polymorphaThe following criteria are followed:
2. Cephalostachyum pergracile
3. Dendrocalamus brandisii
4. D. giganteus
5. D. hamiltonii
6. D. strictus
7. Melocanna baccifera
1. The culms should be healthy and superior.Selection of each species for propagation will be made from at least 6 places along the latitudes and longitudes and also from different altitudes (or from different forest types). Matured culms or clumps of more than 3 years old will be selected.2. In sympodial type a clump must have more than 7 mature culms with at least 5 strong new shoots developing.
3. In monopodial type, a group of more than 6-7 single culms should be selected.
4. Free from diseases and insect attack.
The selected materials will be propagated vegetatively using the methods already known. If seeds are available they will be collected and used.
The propagated materials will be planted in a special plantation.
For utilization research, the industrial processes for timber and wood chemistry section of the FRI is testing bamboos as raw material for producing hard boards, etc.
General survey of bamboos will be carried out in all the states or divisions one at a time basis. Records on bamboos should be compared and updated with on-site checking. Survey in general and selection of superior species of bamboo will lead to establishment of Bambusetum and Bamboo Herbarium.
A bambusetum has been established on 10 ha land in the bamboo growing forest area about 65 km west of FRI, Yezin At least 5 clumps of each species, starting with commercially important species planted.
Bamboo Herbarium is located at the Botany and Tree Improvement Division at FRI, Yezin. Floral specimens will be collected whenever possible and preserved in the herbarium. The collecting of bamboo culms, rhizomes and leaf-sheaths will be made. Many species which are growing in accessible areas will be collected first and the remote areas later.
Uses of bamboos: Bamboo is aptly termed as poor man's timber throughout the tropics. Because of its strength, straightness, lightness, variation in sizes and elasticity etc; bamboo is of immense use. Almost every house has bamboo made utensils. A house can be built using only bamboo materials which would last for at least 10 years. It can be used for scaffolding, ladders, mats, baskets, fencing, containers, pipes, umbrellas, tool handles, spears, bow and arrows, fans, toys, musical instruments, spoons, chopsticks, tooth picks, cooking pots, rafts, binders in place of ropes, fishing rods, furniture, handicrafts and many other articles of daily use (Appendix IV). People eat young bamboo shoots by boiling them in water until they are soft and palatable or cook them mixed with meat and other vegetables, or preserve them for some time wrapped with banana leaves in earth-pits until they become soft and tasty. Bamboos are eaten not only by human beings but also by elephants and other herbivores.
Management of bamboo forests
Felling system: It is suggested to use selection-felling system and clear felling should be avoided. Young and middle age (Wa nu and Tanyin) bamboos should be used for paper pulp and other purposes like making mats and walling materials. Even from the mature bamboos only suitable culms should be cut. It is better to cut culms for thinning clumps. At the same time diseased or injured culms should be removed.
Felling cycle should be 3-6 years. If the ratio of ages of bamboos in a clump is 1:1:3 it means the age of the bamboo forest is about 5 years old. So the felling cycle should be less than 5 years. 1. Felling areas should be demarcated and declared open for felling. If not, felling should not be allowed. 2. Only mature bamboo culms should be harvested. 3. Clear felling should be prohibited. 4. Harvesting of bamboo shoots be only in the open areas, and allow some of them so that young shoots will reach maturity. 5. Undesirable culms should be cleared at the same time.
