THE UNEP WORLD CONSERVATION MONITORING CENTRE is the
biodiversity assessment and policy implementation arm of
the United Nations Environment Programme (UNEP), the
world’s foremost intergovernmental environmental
organization. UNEP-WCMC aims to help decision-makers
recognize the value of biodiversity to people everywhere, and
to apply this knowledge to all that they do. The Centre’s
challenge is to transform complex data into policy-relevant
information, to build tools and systems for analysis and
integration, and to support the needs of nations and the
international community as they engage in joint
programmes of action.
THE INTERNATIONAL NETWORK FOR BAMBOO AND RATTAN (INBAR)
is an international organization established by treaty in
November 1997, dedicated to improving the social,
economic, and environmental benefits of bamboo and
rattan. INBAR connects a global network of partners from
the government, private and not-for-profit sectors in over 50
countries to define and implement a global agenda for
sustainable development through bamboo and rattan.
UNEP-WCMC provides objective, scientifically rigorous
products and services that include ecosystem assessments,
support for implementation of environmental agreements,
regional and global biodiversity information, research on

Foreword
T
he bamboo plant supports an international trade,
which (even according to our currently imperfect
trade statistics) amounts to well over US$2 billion
per year. International trade, however, forms only a part of
bamboo usage, with domestic use estimated to account for
at least 80 per cent of the total. Bamboo is thus a major
world commodity.
Despite this, very little is known about the
distribution and resources of bamboo. Certain bamboo
species (e.g. Chinese Moso bamboo, Phyllostachys edulis)
have formed the basis of major industrial development and
have been domesticated into plantations. Perhaps 50 or 100
bamboo species are preferred for use and are undergoing
some degree of domestication. However there are
estimated to be nearly 1 500 species in total and the vast
majority of these occur only in their native ranges, and many
may have uses of local or wider significance that have yet to
be documented. Unfortunately, as obligate components of
forested ecosystems, their futures are bound up with the
survival of their forest habitats. This work indicates that as
forest ecosystems shrink under human pressure the
4
survival of many potentially important bamboo species may
be threatened.
This work is a first step towards quantifying existing
resources of bamboo. Knowledge of the magnitude and
distribution of these resources is a necessary precursor to
planning and implementing conservation and sustainable
management of bamboos in the wild.
The innovative approach used here can be applied to
the study of other species associated with mapped
ecosystems.
This study would not have been possible without
collaboration between INBAR and UNEP-WCMC. It was the
detailed map-based databases of UNEP-WCMC that made
the development of the methodology possible. This study
thus represents an excellent example of two organizations
working together to combine their strengths.

Preface
W
herever they occur, woody bamboos are of direct
importance to people. They are used for everything from construction to irrigation systems,
from musical instruments to food and fuel. Their greatest
economic importance is in the Asia-Pacific region, but they
are also fundamental to local economies in other regions of
the world. Despite their value to humanity, we still know
relatively little about most bamboos in the wild.
Bamboos are an ancient group of plants that play
a distinctive role in the forest ecosystems of which they
are a part. For example, they support a range of specialized and rare species, such as the greater bamboo lemur
of Madagascar. This report (like its companion volume for
the bamboos of the Asia-Pacific region) applies innovative
approaches and analytical tools to expand our understanding of the ecological role of bamboos substantially.
The authors have generated a revealing overview of the
distribution of bamboos in Africa, Madagascar and the
Americas, which provides the first sound basis for a
description of their importance and an analysis of their
conservation needs.
This work directly supports the Global Strategy for
Plant Conservation, adopted under the Convention on
Biological Diversity, which expressly recognizes the need
for more knowledge on distribution and threats as a basic
requirement for effective conservation measures. A
Global Partnership for Plant Conservation has recently
been formed to help implement the Global Strategy, and
UNEP-WCMC is pleased to be one of its founding
members. By assessing conservation status, identifying
areas important for bamboo diversity and in situ
conservation of threatened species, and providing information on the use of wild species, this report contributes
directly to implementation of the Global Strategy and
achievement of its targets.
Conserving such genetic resources as wild
bamboos is an essential step towards solving the problems of poverty alleviation and sustainable development.
Because of their many uses, bamboos exemplify the
connection between biodiversity and livelihoods very
clearly. This report will help range states to recognize,
and value, the bamboo genetic resources on their own
doorsteps, and to conserve them for future generations.
I welcome this opportunity to collaborate with
INBAR, the world’s bamboo and rattan trade network. I
hope that our first analyses will form the basis for future
in-depth assessments of bamboo resources and their
conservation status. Bamboos are a fascinating group
of plants that bring benefits to people everywhere;
they should be conserved as an important resource for
all our futures.

amboos are distinct and fascinating plants, with a
wide range of values and uses. Although their
diversity and their importance are highest in, and
have been best documented for, the Asia-Pacific region,
they are also important in continental Africa, Madagascar
and the Americas. Worldwide they are associated with
unique elements of biodiversity, many with great
conservation significance. They are important in local cultures and economies, and contribute to soil and water
management. The purpose of the present study is to
synthesize existing knowledge to provide an overview of
the richness and distribution of woody bamboos in Africa,
Madagascar and the Americas. It shows that a number of
bamboo species in these regions are potentially threatened
by the destruction of natural forest cover. Conservation and
sustainable management of wild populations of bamboo
should be a priority, especially where diversity is high or
deforestation is a significant threat.
Bamboos are plants of global interest because of
their distinctive life form, their ecological importance and
the wide range of uses and values they have for humans.
Woody bamboos are an ancient group of forest plants,
which evolved in the lowland tropics of Gondwanaland
during the Tertiary (Clark 1997).
Bamboos are a significant structural component of
many forest ecosystems and play a major role in
ecosystem dynamics through their distinctive cycles of
mass flowering and subsequent die-off, which may
increase the importance of fire (Keeley and Bond 1999).
Inhabiting moister, more benign habitats in old-growth
forests, bamboos are often associated with threatened
plants, and there are many specialized animal species that
depend upon them. There are also many little-known
invertebrates specially adapted to the environment within
hollow bamboo culms. These specialized relationships,
which reflect a long history of co-evolution between
bamboos and other species, can shed light on evolutionary
and ecological processes.
Bamboos are multipurpose crops, with over 1 500
documented uses. Their most important traditional uses
include housing, food and material for handicrafts.
Worldwide, over 2.5 billion people trade in or use bamboo
(INBAR 1999). Globally, domestic trade and subsistence
use of bamboo are estimated to be worth US$4.5 billion
per year, and export of bamboo generates another US$2.7
billion (INBAR 1999). The many uses and the economic
importance of bamboo mean that it plays a considerable
role in improving the livelihoods of rural poor people. The

potentially threatened bamboos outside the Asia-Pacific
region. In this work, we extend the approach used by
Bystriakova et al. (2003a,b) to Africa, Madagascar and the
Americas, to synthesize existing knowledge on bamboo
distribution and identify bamboo species in the three focal
regions that may be of conservation concern.
In East Africa the ‘Endangered’ mountain bongo
(Tragelaphus euryceros ssp. isaaci) relies on montane
bamboo thickets for food and shelter during the dry
season.
rural poor, especially women and children, harvest much
of the bamboo used.
The extensive rhizome system of bamboos lies
primarily in the top layers of soil, so bamboos often play a
major role in stabilizing soils on slopes and river banks,
preventing erosion and land slips. This also makes them
important in securing the hydrological function of
catchments and rivers. Many forest bamboos are
characteristic of high-altitude ecosystems on steep slopes
in zones of high seismic activity, so their role in soil
stabilization may be critical.
The scientific, environmental, economic and
social importance of bamboos means that it is essential
that strategies be developed for their sustainable management. However, knowledge to support such planning
is limited.
Bamboos are of conservation significance in their
own right and may also serve as indicators of high
biodiversity in other groups. As most bamboo species are
forest plants, they are intrinsically vulnerable to
deforestation. The vulnerability of some species is
increased by the simultaneous flowering and subsequent
death of entire populations in cycles of 20-120 years. A
recent study (Bystriakova et al. 2003a,b) showed that
around 40 per cent of bamboos in the Asia-Pacific region
are potentially threatened due to the small amount of
forest cover remaining within their natural ranges. Other
authors have suggested that many bamboos in the
Americas may be of conservation concern (Judziewicz et
al. 1999), and the 1997 IUCN Red List of Threatened Plants
contained 12 species of woody bamboo from the Americas
and one from Africa (Gillet and Walter 1998). However,
there has as yet been little systematic evaluation of
8
STATE OF KNOWLEDGE OF BAMBOOS, BAMBOO
RESOURCES AND THEIR MANAGEMENT
Despite their importance, very little is known about
bamboo distribution and resources, especially in natural
forests. As a non-timber forest product, bamboo is not
routinely included in forest inventories. According to the
FAO (2001), statistical data on bamboo are available for the
period 1954 to 1971 only. Today, very few countries monitor
non-timber forest product (NTFP) supply and utilization at
the national level. The difficulty of assessing bamboo (and
other NTFP) resources and their use arises from:
• uncertainty associated with their taxonomy
(see below);
• the large number of, and wide variation in, their
uses at local, national and international levels;
• the fact that many bamboo products are used
or marketed outside traditional economic
structures;
• the lack of common terminology and units of
measurement (FAO 2001).
The description of bamboos is an ongoing process; not
only do new species remain to be discovered and
described, many earlier descriptions and classifications of
species are being revised. According to Ohrnberger (1999),
the subfamily Bambusoideae (of the family Poaceae, or
Gramineae) comprises both woody and herbaceous
bamboos with 1 575 species altogether. In the most recent
(and narrower) classification (Grass Phylogeny Working
Group 2001) the subfamily Bambusoideae includes two
tribes and approximately 1 200 species.
Although some bamboos have been the subject of
a great deal of research, the majority of species are poorly
known and much of their biology is incompletely
understood. Resources to study bamboos scientifically
have been and remain severely limited. Most international
research funding and effort has focused on a relatively
small set (38) of ‘priority species’ of bamboo that are
commercially important and widely distributed (Williams
and Rao 1994; Rao et al. 1998). Of these, most are native to
the Asia-Pacific region, one (Oxytenanthera abyssinica) is
an African species, none occurs in Madagascar and one
(Guadua angustifolia) comes from South America.
Consequently, research on biodiversity and conservation
of forest bamboos has been especially limited in the three
regions considered here.
Bamboo biodiversity
Perhaps because of their great regional economic
importance, the bamboos of the Asia-Pacific region have
been more thoroughly investigated than those of other
regions. The current understanding of their distribution
and conservation status was summarized by Bystriakova
et al. (2003a,b). Although those publications cover the
majority of the world’s 1 200 bamboo species, around 400
bamboo species and subspecies occur in other regions of
the world and are less well known.
The purpose of the present study is to synthesize
existing knowledge to provide an overview of the richness
and distribution of woody bamboos in Africa, Madagascar
and the Americas. In these three regions the economic
potential of bamboo has not yet been explored and the role
of bamboo resources in national economies is negligible.
The uses of bamboo are mostly in the domestic field and
small-scale construction. As a result, in the majority of
African and American countries, information about
bamboo resources, and their current and potential uses, is
incomplete.
Against a background of poor knowledge of
bamboo identification and distribution it is inevitable that
the vast majority of bamboos have not been evaluated at
all in terms of conservation status, and data deficiencies
may limit the value of any ad-hoc assessments that have
been made. Despite the growing importance of bamboos,
few studies of the conservation status of individual
species have been undertaken. The data compiled in this
study are used to provide a preliminary assessment of
their possible conservation status and are discussed in
the light of the importance of bamboos for both
conservation and human use.
SCOPE AND METHODS
To determine likely present distributions of bamboo
species and to estimate the total area of remaining forest
potentially containing bamboo, we compiled information
on the distribution of bamboo species in each of the three
study regions (Africa, Madagascar and the Americas) from
the relevant taxonomic and floristic literature. This
information was combined with regional data on
remaining forest cover in the same process as used by
Bystriakova et al. (2003a,b) for the bamboos of the AsiaPacific region. The resulting maps for individual species
were combined to show regional patterns of potential
bamboo species richness.
This study was confined to woody bamboos, as
these are most significant from the socio-economic point
of view. We gathered data on nearly 400 species, belonging
to 37 genera, which occur naturally in the three study
regions. For each species bibliographic sources were
searched to acquire data about its distribution. These data
Bamboo has many domestic and agricultural uses,
ranging from musical instruments to construction of
homes and of agricultural structures like this irrigation
system in Madagascar.
were principally political units (country, province, locale),
altitudinal range and forest type. They were entered into
an Access database containing 13 fields and multiple
records for each species (a total of 1 180 records). Although
the information available in the bibliographic sources was
variable, 966 records (82 per cent) contain information
about altitudinal range (minimum and maximum altitude),
and 952 records (81 per cent) have data about species
distribution at the provincial level.
For each species in the database a single potential
distribution map was generated using ArcView Geographic
Information System (GIS) software to combine data on
political units, altitude and forest type according to the
information about natural distribution of the species. The
information about the distribution of existing forest cover
provided by UNEP-WCMC (Iremonger et al. 1997; UNEPWCMC 2000) was used as a mask to eliminate areas not
forested. When multiple data on altitudinal range existed
for the same species, the broadest range was applied. The
individual species maps were combined to generate maps
of potential species richness and potential generic
richness for each of the three study regions.
In an effort to validate the distributions obtained in
this way, a limited number were compared visually with the
point-distributions generated from herbarium specimen
data held in the VAScular Tropicos (VAST) nomenclatural
database of Missouri Botanical Garden (VAST 2003).
In most cases, e.g. Chusquea pohlii (Map 3.23),
Arthrostylidium venezuelae (Map 3.11) and Chusquea
scandens (Map 3.24), the potential species distribution
ranges generated by this study matched the maps of point
locations very well. This suggests that this approach to
modelling based on political units, altitude and forest is an
9
Bamboo biodiversity
appropriate way to generate potential species distribution
maps where data are limited. However, for a minority of
species, e.g. Guadua amplexifolia (Map 3.28) and Otatea
acuminata (Map 3.41), the range of point locations was
larger than predicted by potential species distribution
maps, suggesting that the source data on political units
need verification. It is important to recognize that this study
does not address the persistence of many bamboo species
outside forests and in cultivation, or the potential beneficial
effects of forest disturbance for some woody bamboo
species (Judziewicz et al. 1999).
We gathered data on 388 species and subspecies
that occur in Africa, Madagascar and the Americas, and
mapped the potential current distributions of 379
individual bamboo species within natural forest. Thirtyseven genera occurring naturally in these regions were
included in this study (Annex I).
BAMBOOS IN AFRICA
The lowest diversity of woody bamboos is found in Africa,
where five species representing five genera occur (Table
1). Tanzania has the largest number of species followed
by Malawi, Uganda and Zambia (Table 2). The greatest
potential bamboo richness (two co-occurring species) is
in East Africa, especially around Lake Victoria, and in
southern Africa in Zambia and Zimbabwe (Figure 1), while
the countries of West Africa have only a single species of
woody bamboo (principally Oxytenanthera abyssinica).

The low diversity of bamboo species in mainland
Africa, compared with Asia, Madagascar and the
Americas, may relate to past climatic variation on the
continent. The ancestral woody bamboos are thought to
have arisen in the wet forests of Gondwanaland (Clark
1997). It is possible that after the break-up of
Gondwanaland isolated the African genera (Clayton and
Renvoize 1999), climate and vegetation patterns in Africa
have provided limited opportunities for their expansion
and radiation within forest habitats, in contrast to genera
on other continents.

Conservation and biodiversity importance
Of the African bamboos mapped, only Thamnocalamus
tessellatus has been listed by IUCN as of conservation
concern (Annex II) (Gillet and Walter 1998; Hilton-Taylor
2000). According to our analysis, it currently has 89 260
km2 of potential forest habitat remaining. Potentially of
great concern but not presently red-listed, is Hickelia
africana, which is especially limited in its current extent
(Table 1), having little more than 1 000 km2 of forest
remaining within its range.
Despite their lack of diversity in Africa, bamboos
play an important role in ecology and biodiversity
conservation. In many places, especially at high altitude,
African bamboo species form vast pure stands (Chihongo
et al. 2000; Kigomo 1988), which provide important shelter
and resources for some key species of conservation
interest. For example, the eastern or mountain bongo
(Tragelaphus euryceros ssp. isaaci) of the Aberdare
Mountains in Kenya is considered by IUCN to be
‘Endangered’ (Antelope Taxon Advisory Group 2003). This
large forest antelope spends the wet season in cloud
forests lower down the mountains, but migrates to spend
the dry season in the dense Yushania alpina thickets and
open moorland 1 000 m further up the slopes. Effective
protection of the surviving remnant populations of the
mountain bongo in Kenya is critical to its survival in the
wild. The conservation of bamboo forests is a vital part of
such protection given their key role in sheltering the
mountain bongo during the dry season.
Another close dependence between an endangered mammal and bamboo occurs with the eastern
mountain gorilla (Gorilla beringei beringei). Mountain
gorillas, which are classed as ‘Endangered’ (IUCN 2002),
inhabit montane and bamboo forests in the eastern
Democratic Republic of the Congo, Rwanda and
southwestern Uganda (IGCP 2003). They eat large
amounts of vegetation from more than 70 different plant
species, including bamboo (Fossey and Harcourt 1977).
When the bamboo plant sprouts in June and November,
bamboo shoots can make up to 90 per cent of a gorilla’s
diet. An adult male can eat up to 35 kg of bamboo each day,
and females about 18 kg (WWF 2003a).
Uses of bamboo
In terms of utilization, the most important African species
are Oreobambus buchwaldii, Oxytenanthera abyssinica
and Yushania alpina (Annex III and Annex V: Maps 1.1, 1.2
and 1.4). These are mostly harvested from the wild. For
example, in Kenya only 0.6 per cent of total bamboo
harvested is produced on farms (Ongugo et al. 2000).
African bamboos have not been exploited in pulp
and paper production, or in any other large-scale bamboo
11
Bamboo biodiversity
industry. The economic value of trade in bamboo products
in Africa is negligible. Since the products are traded
locally, statistics do not enter the national accounting
systems (Chihongo et al. 2000).
Although there is little cultivation of bamboo and
little or no international trade in bamboo from Africa,
many bamboo products are used domestically and can be
very significant in both household and local economies.
Key bamboo uses include small-scale construction,
handicrafts, residential fencing, horticultural flower
farming, water pipes, farm props for banana plantations,
furniture, and other minor cottage industry products like
basketry and toothpicks (Chihongo et al. 2000). According
to the results of a survey carried out in several Ethiopian
states (Kelbessa et al. 2000), the majority of rural families
were entirely dependent on raw bamboo for construction,
household furniture and as a source of domestic energy.
Where collecting and processing bamboo provides income,
as for example in the production of toothpicks and incense
sticks in Kenya, women are mainly involved in processing
whereas men are involved in harvesting, transportation
and processing (Ongugo et al. 2000).
In some parts of Africa, bamboo is also a source of
food and drink. In Tanzania and Uganda, young shoots and
seeds of Oxytenanthera abyssinica, a medium-size
bamboo reaching 8-16 m in height, are consumed as food.
The principal use of this species in Tanzania, however, is in
the production of bamboo wine, also known as ulanzi
(Chihongo et al. 2000; Kigomo 1988). Tips of young shoots
are cut off and the stem portion bruised every morning and
evening for about a week. The exudate from the bruises is
collected and allowed to stand for two days to ferment. The
resulting ulanzi, which is 5-5.5 per cent alcohol, is one of
the principal forms of alcohol consumed in some areas
(Willis 2003).
.
Other roles of bamboo
The role of bamboo in conserving soil and protecting
watersheds is also substantial in Africa. For example, in
Kenya, Yushania (formerly Arundinaria) alpina is receiving
attention from the government especially for catchment
rehabilitation, regulation of water-flow and erosion control
(Ongugo et al. 2000).
Conservation and management
The importance of bamboos and their products in local
economies has led to overexploitation and a decline in the
supply of bamboo from natural stands in some parts of
Ethiopia and Tanzania (Chihongo et al. 2000). Approaches
to reverse these trends have included efforts to establish
introduced species. The Kenya Forestry Research Institute
has introduced several bamboo species from Asian
12
countries both to forest areas and on farmlands on an
experimental basis (Ongugo et al. 2000; Kigomo 1999). A
number of species, among them Bambusa bambos, B.
tulda, B. vulgaris, Dendrocalamus asper, D. brandisii, D.
membranaceus, D. strictus, Phyllostachys pubescens and
Thyrsostachys siamensis, have been established
successfully in several ecological zones.
Regulation has also been used as a means to
ensure continued supply of bamboo in parts of Africa. In
Uganda bamboo harvesting is allowed in some areas, but
collectors have to obtain permits from the Forestry
Department. In Kenya bamboo in state forests is
protected, although controlled harvesting is allowed in
places (Ongugo et al. 2000). A government ban on cutting
bamboo was proclaimed in 1982 to control further
indiscriminate cutting and to allow the overcut areas to
regenerate to their full potential. Bamboo harvesting from
state forests was allowed only with a special licence.
However, regulation is not always a successful
approach. Even in Ugandan forest reserves with no legal
public access, illegal harvesting of bamboo occurs (Esegu
et al. 2000). Implementation of the government ban in
Kenya has resulted in conditions that have encouraged
corruption and made the bamboo resource unavailable to
poor entrepreneurs. A rough comparison of the figures for
the bamboo actually used and the official figures for
harvested bamboo shows a difference of 88 per cent,
which means that a large part of the bamboo used in
Kenya is harvested illegally (Ongugo et al. 2000).
Further work is needed to identify appropriate
mechanisms and regimes for managing bamboo
resources, ensuring conservation of native bamboo populations and maintaining their roles in forest ecosystems.
BAMBOOS IN MADAGASCAR
Information about bamboos in Madagascar is far from
complete. Although bamboos began to be described in
Madagascar in 1828, there was a long hiatus during the
latter half of the 19th century. Limited collection during the
early 20th century permitted the description of a total of 27
species up to 1960. New collections between 1987 and 1996
permitted recent revisions of Hickelia and Decaryochloa
and descriptions of three new genera, Valiha,
Cathariostachys and Sirochloa (Dransfield 2000; Dransfield
2002). It is likely that additional revisions and some new
species descriptions may be produced in the future.
At present, Madagascar is considered to have 33
species of woody bamboo and is therefore strikingly more
rich in species than continental Africa. Thirty-two of those
species are endemic and a single species, Bambusa
vulgaris, is pantropical in distribution. As this last species
is found principally near villages and along rivers, it is

possible that it is introduced. The richness and endemism
of the woody bamboo flora of Madagascar reflects the
island’s long (c. 140 million years) isolation from other
land masses and the resulting unique evolutionary
pathways that have led to extremely high levels of
endemism in both flora and fauna.
The majority of the native woody bamboos of
Madagascar are found on the eastern escarpment where
remnants of rainforest still exist (Figure 2). Some species
also occur in the drier vegetation of the west. The
maximum potential species richness in Madagascar
identified by the present study was seven co-occurring
species.
Conservation and biodiversity importance
In addition to being endemic, a number of Madagascar’s
woody bamboos have limited amounts of forest remaining

within their quite localized ranges. Twenty-five of the
Madagascan species have less than 20 000 km2 of forest
remaining within their ranges and as many as ten species
have less than 2 000 km2 of forest available to them (Figure
3 and Annex IV). Although the former criterion might be
considered analogous to the threshold extent of
occurrence used by IUCN as a basis for inclusion in the
Red List, none of Madagascar’s woody bamboos is
currently listed by IUCN as a plant species of global
conservation concern (Gillet and Walter 1998; HiltonTaylor 2000).
Besides their endemism and potentially
threatened status, a number of Madagascar’s woody
bamboos are fundamental to the survival of other species.
The most extreme case may be that of the bamboo lemurs.
There are three recognized species of bamboo lemur, each
occupying a different habitat in Madagascar: the grey
bamboo lemur (Hapalemur griseus), the greater bamboo
lemur (Hapalemur simus) and the golden bamboo lemur
(Hapalemur aureus). All these species are characteristic
of forest with a high proportion of bamboo, and various
parts of bamboo plants make up a large part of their diets.
The grey bamboo lemur lives on the new shoots, leaf
bases, and sometimes pith of several bamboo species
(Garbutt 1999; Mittermeier et al. 1994). The rare greater
bamboo lemur primarily consumes the pith of the giant
bamboo, Cathariostachys madagascariensis, which contains high levels of cyanide (Garbutt 1999; Dransfield
2000). The golden bamboo lemur eats leaf bases and new
shoots of the same bamboo species, as well as other nonwoody bamboos (Garbutt 1999).

Bamboo biodiversity
Although the bamboo lemurs are threatened by
rainforest destruction, at least one group, the western grey
bamboo lemur, may actually benefit from low levels of
forest disturbance, which increase the density of bamboo.
The grey bamboo lemurs are at relatively low risk (the
eastern subspecies is classified as ‘Lower Risk’, and the
western as ‘Vulnerable’), but both the other two species
are ‘Critically Endangered’ (Hilton-Taylor 2000).
Other animals besides lemurs are dependent on
bamboo. There is a community of rainforest organisms
that rely on so-called bamboo wells, cavities in fallen
bamboo culms that fill with rainwater. Some use them for
reproduction, others for shelter and to escape from
potential predators. Mantella laevigata, a species of
poison frog endemic to northeastern Madagascar, breeds
in water-filled tree holes or broken bamboo. The frogs are
found in association with Bambusa vulgaris, Valiha diffusa
and other native bamboo species. The frogs’ eggs often
become food for other animals. For instance, crane flies
(Limonia renaudi) lay eggs in the water of the same
bamboo wells, and their larvae feed on the eggs of
Mantella (Heying 2001).
The bamboo forests in the drier western part of
Madagascar are the habitat of one of the most endangered
reptiles in the world, which is also the rarest tortoise, the
angonoka or ploughshare tortoise (Geochelone yniphora)
(WWF 2003b).
Conservation and management
The destruction of native vegetation in Madagascar is a
major problem, which has been recognized for a number of
years. According to IUCN (1992), at least 80 per cent of the
land surface of the island no longer has significant native
woody plant cover. Green and Sussman (1990) calculated
that all but 34 per cent of the eastern rainforests had been
lost by 1985, and high rates of deforestation have
continued. Conservation International estimates that less
than 10 per cent of the original vegetation of Madagascar
remains (Myers et al. 2000). The expansion of small-scale
agriculture and the harvesting of wood for charcoal
production and forest fires continue to threaten the
remaining forests.
These alarming figures help to explain why so
many of Madagascar’s endemic woody bamboo species
have little forest habitat remaining within their ranges.
While some bamboos persist and may even proliferate in
disturbed landscapes, others are less resilient and many
of the species that depend on bamboos require a forest
environment. Improving management of the 3 per cent of
Madagascar currently officially protected (Conservation
International 2003) should help to conserve many of the
endemic bamboos. However more direct attention is
needed to determine the conservation status of bamboo
species and identify the priority actions for ensuring their
conservation in situ.
Uses of bamboo
Bamboos are also extremely important to local
communities in Madagascar. Nearly half of all households
use bamboo domestically (Ferraro 2001): for construction
and for items ranging from handicrafts to musical
instruments. For example, the culms of Valiha diffusa are
used for the construction of walls and roofs; they are split
on one side and flattened, then woven into large panels.
Bamboo is also used for flooring and fencing, and in
irrigation systems. Water containers, fishing traps and
poles, darts, baskets and storage containers are all made
from a number of bamboo species. Culms of Valiha are
used to make the traditional musical instrument, the tube
zither or valiha, and those of another endemic genus,
Cathariostachys, are used for making flutes (Dransfield
2000).
Much of the bamboo used domestically comes
from secondary forests, and there are some plantations in
and around villages. However, in some areas villages have
depleted the available supply of bamboo nearby and
residents must travel greater distances to obtain
resources (Ferraro 2001).
Bamboo is traded domestically in Madagascar on a
small scale, but not internationally.
BAMBOOS IN THE AMERICAS
The Americas are collectively much richer in bamboo
species than either continental Africa or Madagascar, but
have lower diversity than the Asia-Pacific region
(Bystriakova et al. 2003a). There are currently 20
recognized genera of woody bamboos that are confined to
the New World. Only Arundinaria occurs in both the Old
and New Worlds. There are approximately 430 species of
New World woody bamboos, of which more than 40 per
cent belong to a single genus, Chusquea (Judziewicz et al.
1999).
The greatest diversity of bamboos in the New
World is in South America. Brazil has nearly twice as many
bamboo species as Venezuela and Colombia, which are in
turn nearly twice as rich as the richest Mesoamerican
countries (Costa Rica and Mexico; Table 3). The United
States has only a single woody bamboo species, as do
many Caribbean island nations.
Previous studies have identified the areas of
highest bamboo diversity and endemism in the New World
as Brazil, the northern and central Andes and Mexico,
along with the still poorly known Guyana Highlands
(Judziewicz et al. 1999). The results of our study confirm
this and identify São Paulo state as the area with the

Bamboo biodiversity
Conservation and biodiversity importance
Currently, the IUCN Red List of ‘Endangered’ bamboos in
the Americas comprises 20 species, among them 12
woody bamboos (see Annex II) (Gillet and Walter 1998;
Hilton-Taylor 2000). The present study has identified
nearly 200 New World woody bamboo species with less
than 20 000 km2 of forest remaining within their potential
ranges (Annex IV). Ninety-five of these species occur
where there are less than 2 000 km2 of forest (Figure 5).
Throughout the Americas, woody bamboos are an
important part of forested ecosystems and occur in
almost homogeneous stands in some places. Bamboodominated areas in the Amazon region occupy between
121 000 and 180 000 km2 (Nelson 1994; Judziewicz et al.
1999). This vegetation, which is dominated by bamboos of
the genera Guadua, Elytrostachys and Arthrostylidium, is
dense and often impenetrable because of the thorns of
the bamboo. In northern South America, especially
Colombia and Ecuador, the ‘guadual’ – dense bamboo
forest dominated by Guadua angustifolia – is an important
vegetation type at low to mid-altitude. This is often an
important refuge for wildlife species from surrounding
native hardwood forests that are being destroyed
(Judziewicz et al. 1999).
The mechanism by which bamboos become
dominant in these areas is unclear, though it is likely that
clonal growth following disturbance by wind, fire and

largest number of potentially co-occurring woody bamboo
species (35) (Figure 4).
At generic level, woody bamboo diversity appears
to be concentrated in the Brazilian state of Minas Gerais
(nine co-occurring genera), whereas other authors have
reported higher generic diversity of all bamboos (woody
and herbaceous combined) in the coastal state of Espírito
Santo (Burman and Filgueiras 1993). Of the five monotypic
genera in the Americas (Arundinaria, Actinocladum,
Athroostachys, Criciuma, Eremocaulon), four coincide in
an area covering the states of Mato Grosso, Bahia and
Minas Gerais, Brazil (Arundinaria is distributed solely in
the United States). This confirms the importance of the
Atlantic Forest region for the diversity of woody bamboos
in South America.
To a large degree, these patterns may reflect the
state of knowledge as a result of the distribution of
collecting effort (Burman and Filgueiras 1993), and the
true pattern may yet prove to be somewhat different.
However, they are consistent with suggestions that the
Atlantic coastal zone may have provided diverse habitats
that fostered bamboo evolution and/or facilitated bamboo
survival during cold glacial maxima (Judziewicz et al.
1999).

landslips plays an important role. It has been suggested
that bamboos may also significantly increase the potential
for some types of natural disturbances (Keeley and Bond
1999). According to this hypothesis, mass mortality in
bamboos after fruiting generates a widespread and
synchronous fuel load that significantly increases the
potential for wildfire. The resulting canopy disturbance
both increases resources for seedling recruitment and
resets the successional cycle to favour persistence of the
new clones. The dense and rapid growth of woody
bamboos may suppress the regeneration of other woody
species (Clark 1995). The aggressive growth strategy of
such species as Guadua weberbaueri and G. sarcocarpa
can alter the normal forest succession process following
small or large-scale forest disturbance. This may contribute to the high levels of endemism and species
diversity evident in some regions where these species are
prominent (Kirkby 2003). In some areas, woody bamboos
have become invasive and dominate forest succession in
abandoned cultivation, excluding regeneration of native
tree species (WWF 2003c). Bamboos therefore play an
important role in determining forest structure and
dynamics.
Throughout the Americas, bamboo stands provide
habitat and food for a wide range of mammals, birds,
amphibians and invertebrates, many of which are of
conservation concern. In South America, especially at
higher altitudes and in the Atlantic Forest zone, several
important mammals feed on bamboo. The spectacled bear
(Tremarctos ornatus), which is classified as ‘Vulnerable’
by IUCN (Hilton-Taylor 2000), feeds opportunistically on
Bamboo biodiversity
young shoots of bamboo (Judziewicz et al. 1999).
‘Endangered’ mountain tapirs (Tapirus pinchaque) eat
considerable amounts of grasses, bamboo, sedges and
bromeliads in their high-altitude habitats (Downer 1996).
The ‘Vulnerable’ lowland tapir (Tapirus terrestris), which
feeds on grasses and aquatic plants in the Amazon,
consumes substantial amounts of bamboo leaves and
twigs in the Atlantic Forest (Rodrigues et al. 1993).
At least four South American rodent species known
as bamboo rats (Dactylomys dactylinus, D. peruanus and
D. boliviensis in Amazonia and Kannabateomys amblyonyx
in the Atlantic Forest) use bamboo patches as their
principal habitat and also eat bamboo (Nowak 1995;
Haemig 2003a,b).
At least 4-5 per cent of all the bird species that
occur in Amazonia are dependent on bamboo, and 34 bird
species are reported to be confined to bamboo thickets in
at least one of the regions of Amazonia (Haemig 2003a). In
the Atlantic Forest, which extends along the coast of
eastern Brazil into neighbouring parts of Argentina and
southeastern Paraguay, at least 27 bird species were
reported to be confined almost entirely to large stands of
bamboo, or most abundant where bamboo is common, or
to forage most extensively on bamboo (Haemig 2003b). In
at least one case, that of the uniform finch (Haplospiza
unicolor), the life cycle of a bird species is synchronized
with that of mast-seeding bamboos (Chusquea spp.), so
that this finch breeds in the austral autumn rather than
the austral spring (Haemig 2003b). Of the Atlantic Forest
bird species associated with bamboo, 11 are of
conservation concern (Table 4).
The water that accumulates in bamboo internodes
provides important habitat for numerous invertebrates
(Judziewicz et al. 1999) and some amphibians. Furthermore, evidence is emerging of complex ecological
relationships between forest bamboos and ant species
that inhabit their internodes and defend them from attack
by herbivores (Davidson et al. 2003).
Canebrakes, dense stands of Arundinaria gigantea,
were once widespread throughout the southeastern
portion of the United States, where they provided shelter
and resources for rare species such as the ‘Critically
Endangered’ Bachmann’s warbler (Vermivora bachmani)
and the now ‘Extinct’ Carolina Parakeet (Conuropsis
carolinensis) (Judziewicz et al. 1999). Other species that
rely on canebrakes include at least five species of
butterfly, which require the cane as food during the
caterpillar stage (Hendershott 2002). These important
habitats have been much reduced by development,
drainage and suppression of the fire regime that was
important to their maintenance, with resulting adverse
effects on the species that depend on them.

Uses of bamboo
The Americas have never had a ‘bamboo culture’ in the
way that Japan and China may be said to have had. The
exploitation of native bamboo in Latin America is limited to
the local use of species found close by. It is only in
Colombia, Ecuador and Brazil that bamboo plays a more
conspicuous role in the local economy (Londoño 2001).
Nonetheless, bamboo is of local importance throughout
the region, and many species are used.
The most useful species in Latin America are found
in the genus Guadua, and there are several others in the
native genera of Apoclada, Aulonemia, Chusquea,
Elytrostachys, Otatea and Rhipidocladum. Bambusa,
which has been introduced from Asia, is also extensively
used. Cultivation of bamboos on a commercial scale is
limited to only a few native (Guadua angustifolia, G.

implemented several construction projects in Colombia.
Among them is a bamboo bridge with a span of 52 m.
amplexifolia) and introduced (Bambusa vulgaris, B.
tuldoides, Phyllostachys aurea) species (Londoño 2001).
Bamboo has a long history of use in construction in
Central and South America, where it is a common part of
the vernacular architecture. This is particularly widespread in southern Colombia and northern Ecuador,
where bamboo (mostly Guadua angustifolia) has been
extensively used in houses that have stood for 50-100
years on unstable sites such as steep slopes, earthquakeprone regions or swampy coastal areas that are frequently
inundated (Gutierrez 2000).
Contemporary architects are also increasingly
using bamboo. Through new techniques, bamboo has
been combined with modern materials like reinforced
concrete or steel to create some extraordinary structures
including luxury housing, bridges and observation towers.
These architects have made a deliberate attempt to
increase social acceptance of bamboo and promote its
adoption as an inexpensive and environmentally friendly
building material among both rich and poor (Gutierrez
2000). Prefabricated panels made of flattened Guadua
culms are distributed in Ecuador as part of low-cost
housing programmes (Judziewicz et al. 1999).
Studies have been undertaken to explore the use of
native South American bamboos for making paper, but the
two Guadua species (G. angustifolia and G. amplexifolia)
examined proved to have fibre lengths much inferior to
Bambusa vulgaris. More than 100 000 ha of this introduced
species are cultivated for paper production in Brazil, which
is the only New World country to use bamboo for making
paper (Judziewicz et al. 1999; Itapagé 2003).
Throughout the Americas indigenous people use
woody bamboos to make handicrafts and musical
instruments. Baskets, fans, utensils, toys, furniture and
18
agricultural supports are all made from bamboos of
different types. Musical instruments ranging from flutes to
drums are also produced from bamboo. In particular, the
pan pipes and quena flutes so characteristic of Andean
music are made from cloud-forest bamboos, either
Aulonemia queko or Rhipidocladum harmonicum
(Judziewicz et al. 1999).
Though to a much lesser extent than in Asia,
bamboos are a source of food both for humans and for
livestock in the Americas. Indigenous groups eat the fruits
and seeds of several species, and some use of bamboo
shoots as food has been reported (Judziewicz et al. 1999).
The bamboo of North American canebrakes has long been
recognized as an especially rich forage and was much
prized for this purpose by both aboriginal and colonial
pastoralists (Hendershott 2002).
Annex III provides a summary based on published
literature of the most used woody bamboos of the
Americas and the purposes to which they are put in
different parts of the region.
Conservation and management
In many parts of the New World, forest ecosystems were
destroyed long ago or are currently under threat. The
forests of the southeast United States were severely
depleted during colonial times and reached their
minimum extent around 1860. The rapid rate of forest loss
in the Amazon has been well publicized in recent years.
While vast tracts of forest still remain, the rate of
deforestation has recently increased again (INPE 2002).
The Atlantic Forest has been reduced to less than 8 per
cent of its original area and is under continuing threat
(Burman and Filgueiras 1993; Myers et al. 2000). These
trends help to explain the high proportion of American
bamboos that now have very limited areas of forest within
their ranges.
These results suggest that many woody bamboos
in the Americas are potentially threatened if they depend
on forest habitat for their survival, and that carefully
planned and implemented conservation measures are
needed to ensure the continued survival of many bamboo
species. Bamboo-dominated ecosystems need to be
carefully assessed and monitored to ensure that their
status is thoroughly understood and that measures are
taken to protect them where needed. For example,
forested canebrake communities in the United States are
now listed as ‘Critically Rare’ by the National Biological
Survey and as ‘Globally Rare’ by the Nature Conservancy
(Hendershott 2002), prompting increased efforts for their
protection and restoration. In other cases, the ecology of
native bamboos as invasives in disturbed landscapes
needs further investigation as does their role in

CONCLUSIONS AND SUGGESTIONS FOR FURTHER WORK
This study has shown that many woody bamboos in
Africa, Madagascar and the Americas may be of
conservation concern, despite the fact that they are not
presently included in global Red Lists. It has highlighted
the richness and distinctiveness of the bamboos of
Madagascar and the even greater richness of the
Americas at both generic and species levels (Figures 6
and 7). The study has also made it clear that significant
further effort will be required to assemble an accurate
overview of the magnitude and distribution of woody
bamboo resources in these regions. Such information is
needed to support wise policy-making and management
decisions, and to facilitate progress towards the

species (cf. Rao et al. 1998) to take account of
the utility and/or economic importance of
bamboos from Africa, Madagascar and the

inconsistencies and inadequate knowledge
of the distribution of woody bamboo
species, and clarifying the ecological roles of
woody bamboos, through research-based,
national capacity-building and international
collaboration.
5. Developing appropriate methods for assessing
bamboo resources and the pressures on them,
and incorporating these methods into NTFP
elements of national forest inventories.
6. Assessing the value of existing reserves and
reserve networks for conserving the biological
diversity of bamboos.

Africa, Madagascar and the Americas
Bamboos are distinct and fascinating plants, with a wide range of values and
uses. They play a significant role in biodiversity conservation, are important to
ecosystem dynamics, and contribute to soil and water management. They play
an increasing role in local and world economies.
This study used an innovative approach to map potential current
distributions of nearly 400 individual bamboo species that occur naturally
within the remaining forests of Africa, Madagascar and the Americas. The
maps were also combined to generate regional maps showing potential
species and generic richness.
By quantifying the area of forest cover remaining within each species’
range, this analysis shows that over half the species studied are potentially
threatened by the destruction of natural forest cover. The situation is particularly alarming in Madagascar, where the woody bamboos are all endemic
and 75 per cent of them have only very small amounts of forest remaining
within their ranges. Conservation and sustainable management of wild populations of bamboo should be a priority in all three regions, especially where
diversity is high or deforestation is a significant threat.
This report contributes to implementation of the Global Strategy for
Plant Conservation, which aims to halt the current and continuing loss of
plant diversity.
