The Red List of Trees of Central Asia
FOREWORD
T
rees are important to the well-being
of people in every country of the
world,
providing
essential
ecological, economic and cultural
services. In Central Asia, a vast and varied
region with generally relatively low forest
cover, tree species are of great value in
defining forest ecosystems and providing
resources such as fuelwood, timber, fruits
and nuts. In fact the genetic diversity of
fruit and nut trees within the region is of
outstanding global significance. As
elsewhere in the world, the trees of
Central Asia face an onslaught of threats
from habitat destruction, over-grazing,
over-harvesting and the increasing impact
of global climate change. This report
presents a review of the conservation
status in the wild of the trees of Central
Asia, facilitated by FFI and the IUCN/SSC
Global Tree Specialist Group.
Since its establishment in 2003 the
primary role of the IUCN/SSC Global Tree
Specialist Group has been to assess the
global conservation status of tree species
in selected geographical areas and
taxonomic groups. This report is the fifth
publication in the series.
The collection of information on tree
species of conservation concern is vital for
planning conservation action. The
secondary role of the IUCN/SSC Global
Tree Specialist Group is to act as an
advisory body for the Global Trees
Campaign, which aims to save the world’s
most threatened tree species and the
habitats where they grow. The Global
Trees Campaign provides an important
practical mechanism for implementation
of the Global Strategy for Plant
Conservation of the Convention on
Biological Diversity. Global tree red listing
contributes directly to Target 2 of the
Strategy, which calls for a provisional list of
threatened plant species by 2010.
4
In many ways Target 2 underpins the
other ambitious targets that relate to in
situ and ex situ conservation and
sustainable use and trade in plants.
Projects of the Global Trees Campaign
carried out in partnership with
organizations and individuals around the
world help to deliver these various targets.
The projects contribute to halting the loss
of forest biodiversity and the provision of
support to rural livelihoods.
The Global Tree Specialist Group is
committed to undertaking a global
assessment of the conservation status of
tree species. Results of the global
assessment will be published as
components of the work are completed.
This will ensure that regular indicators of
progress are produced, updated tree
conservation data are made widely
available and that tree conservation
initiatives around the world can be
supported.
This report highlights 67 tree species that
are globally threatened, near threatened
or of concern because of insufficient
information on their status in the wild. It
highlights the actions that urgently need
to be undertaken to prevent the extinction
of these species. Fortunately we have the
ability to act, working with nature
conservation and forestry agencies,
botanic gardens and germplasm banks of
the region. Fauna & Flora International and
Botanic
Gardens
Conservation
International, the international partners in
the Global Trees Campaign, are
committed to helping save these tree
species from extinction.

The Red List of Trees of Central Asia
INTRODUCTION
Central Asia forms a vast region that
stretches from the Caspian Sea in the
west to the great Tien Shan mountain
range in the east. The region is
composed of five independent republics:
Kazakhstan, Kyrgyzstan, Tajikistan,
Turkmenistan and Uzbekistan. All five
countries were once part of the Soviet
Union until their independence in 1991.
The largest of the Central Asian countries
is Kazakhstan, with a total land area
of just over 2,700,000 km2. Tajikistan
is the smallest country, occupying
143,100 km2.
Central Asia is a region of contrasting
landscapes. In the west it is dominated
by the barren, rocky Ustyrt Plateau and
the vast Turan Plain, with the Kara-Kum
Desert in the south and the Kyzyl-Kum
Desert in the centre. The Kopetdag
Mountains in the south-west form a
natural border between Turkmenistan
and Iran. The extensive lowland plains in
the west and centre of the region,
comprising largely desert and arid
steppe, eventually give rise to the uplands
and then the great mountain ranges of
the Tien Shan, the Altai and the Pamir.
The highest peaks in Central Asia are
Ismoil Somoni Peak (7,495 m), Pobedy
Peak (7,439 m) and Lenin’s Peak
(7,134 m). At altitudes above 3,500 m
permanent snow, rock and glaciers
dominate the landscape. Although the
region is largely arid, a number of large
rivers such as the Amu-Darya and the
Syr-Darya flow down from the mountains
to form lakes such as Issyk-Kul in
Kyrgyzstan and the Aral Sea, which lies
on the border of Kazakhstan and
Uzbekistan. These large rivers are
responsible for the verdant, fertile valleys,
such as the Fergana Valley, which today
are intensively irrigated for crops.
The vastness of the region (almost
4,000,000 km2), its landscapes and
altitudinal zonation have led to a wide
range of ecosystem types that include
steppe, riparian tugai, taiga, wetlands,
snowfields and deserts. These in turn are
home to threatened species such as
snow leopard Uncia uncia, saiga antelope
Saiga tatarica tatarica and beluga
sturgeon Huso huso.
The region supports some 8,300 species
of vascular plants (Kamelin, 2002) of
which approximately 10% are thought to
be endemic. The mountains of Central
Asia are a recognized global biodiversity
hotspot (Davis et al., 1995), supporting
over 300 wild fruit and nut species. These
include wild species of apple (four
species), almond (8–10 species), cherry
(8–10 species), plum (4–5 species), and
walnut (one species) as well as many
domesticated varieties. The rich diversity
of fruit and nut species in the region led
the Russian geneticist and plant breeder
N.I. Vavilov to propose it as one of the
world’s eight centres of crop origin and
domestication (Hawkes, 1998). In fact,
recent molecular genetic studies strongly
support the hypothesis that the domestic
apple originated from Kazakhstan (Harris
et al., 2002).
There are 500–600 arborescent species
in Central Asia, of which 100–150 can be
classified as trees, the remainder being
shrubs (Lazkov, pers. comm., 2008). This
includes taiga species such as Abies
sibirica and Picea schrenkiana as well as
desert shrubs such as Haloxylon
persicum and H. aphyllum. High species
diversity and endemism is particularly
notable in the shrubby genera
Calligonum,
Tamarix,
Astragalus,
Cotoneaster, Rosa and Crataegus.
FORESTS AND WOODLANDS OF
CENTRAL ASIA
The aridity of the region means that the
proportion of land under forest or
woodland is relatively low when compared
to more humid regions such as South
America. Tajikistan has the least, with
around 3.9% of its total land area covered
by forest or woodland, whilst Uzbekistan
has the most, with 10.1% of its land
wooded (FAO, 2006a). Kyrgyzstan,
Kazakhstan and Turkmenistan have 6.2%,
7% and 8.8% forest and woodland cover
respectively. A large proportion of the
woodland
in
Kazakhstan
and
Turkmenistan is composed of desert
saxaul Haloxylon spp. shrublands (FAO,
2006a). Located primarily in the
mountains, the forests of Central Asia play
a pivotal role in environmental protection,
preventing soil erosion and desertification,
and regulating watersheds.
Despite the relatively low forest/woodland
cover, Central Asia supports a diverse
range of forest and woodland types,
some of them unique to the region. The
main and most notable forest and
woodland types of the region are:
Saxaul Haloxylon spp. shrublands can
be found in the desert and arid steppe
regions, mostly in Turkmenistan and
Kazakhstan. These shrublands, which
typically include drought resistant species
such as Salsola, Calligonum and
Elaeagnus, play an essential role in
preventing soil erosion.
Riparian tugai is restricted to the
floodplains of the region and is found
alongside river courses and streams.
Tugai is typically composed of a mixture
of willow Salix spp., poplar Populus spp.
and birch Betula spp..

The Red List of Trees of Central Asia
Broadleaved fruit and nut forests are
found in the foothills and slopes of the
Tien Shan, Pamir-Alai and the Kopetdag
mountains between 800–2,000 m. These
fragmented forests are incredibly rich in
wild fruit- and nut-bearing species such
as walnuts Juglans regia, apples Malus
spp., pears Pyrus spp., plums Prunus
spp. and almonds Amygdalus spp..
environmental protection, recreation and
wildlife management (FAO, 2006a).
Central Asian forests are regionally
recognized as being essential in
protecting common watersheds and
arresting
land
degradation
and
desertification.
Pistachio Pistacia vera woodlands are
found on the lower, drier foothills and
mountain slopes of western Tien Shan,
Pamir-Alai and Kopetdag. One of the
most notable areas of pistachio is in the
Badghyz
Strict
Nature
Reserve
(Turkmenistan), where the trees form
extensive open groves covering around
76,000 ha (MNPT, 2002).
State forestry enterprises are also
responsible for the management of some
forested protected areas, such as the
Badai-Tugai Strict Nature Reserve in
Uzbekistan. The rest of the protected
areas tend to be managed by nature
protection agencies. All five Central Asian
countries largely inherited the former
Soviet system of protected areas, which
includes Strict Nature Reserves
(zapovedniks), National Parks, Nature
Monuments and Special Purpose
Reserves (zakazniks). The highest
protection is provided by zapovedniks
(IUCN Category I), whilst zakazniks have
the least protection (IUCN Category IV).
To date, there are 39 zapovedniks, 14
National Parks, some 67 Nature
Monuments and around 150 zakazniks in
Central Asia. These numbers are likely to
increase in the near future as more
protected areas are designated. A
number of zapovedniks were established
to conserve distinct forest types such as
the Zaaminsky State Reserve (unique
juniper forest) in Uzbekistan and Sary
Chelek Biosphere Reserve (fruit and nut
forest) in Kyrgyzstan.
FOREST MANAGEMENT AND
NATURE CONSERVATION
The majority of the forests and
woodlands in Central Asia are still owned
by the state, and management is still
largely based on the Soviet system of
state forestry enterprises or leskhozes
(FAO, 2006a). The main objectives of
forest management in all the Central
Asian countries are focused on
The political and economic collapse of the
Soviet Union between 1989 and 1991 has
had a profound effect on all the Central
Asian countries, with consequences
including war and civil unrest (UNDP,
2005). The ensuing sharp economic
decline has had a huge impact on
people’s lives in the region, with nature
conservation
and
environmental
protection subsequently receiving low
Juniper (archa) woodlands/shrublands
are found typically in the dry foothill
regions or at mid to high altitude (up to
3,500 m above sea level), where they
take on prostrate forms. Species include
Juniperus seravschanica, J. semiglobosa
and J. turkestanica.
Taiga forests comprising predominantly
spruce and fir species are restricted to
the northern slopes of the Tien Shan
between 1,700 m and 2,700 m. Typical
species include Picea schrenkiana and
Abies sibirica. The endemic Semenov fir
Abies semenovii is restricted to small
areas in western Kyrgyzstan.

priority. The majority of protected areas
and leskhozes are severely underresourced and lack the necessary
institutional capacity, financial support and
expertize for the effective management of
biodiversity and law enforcement (MEP,
1998; MNPT, 2002; Cornet and
Rajapbaev, 2004; Jashenko, 2006).
FOREST USE
Despite the low forest cover in Central
Asia, the people of the region have
always had a strong association and
dependency on forests to provide
firewood, timber and food (nuts, fruit,
mushrooms and honey). In fact, the name
of Kazakhstan’s former capital, Almaty,
literally means ‘the Father of Apples’. The
long association of humans with apples
in the region is demonstrated by the lack
of distinction between some wild species
and their cultivated varieties (Juniper and
Mabberley, 2006).
Wood fuel is still important in Kyrgyzstan
and Tajikistan where a high proportion of
the population live in rural areas and do
not have access to fossil fuels. In
Tajikistan more than 80% of rural
households rely on wood fuel as a main
source of cooking energy (FAO, 2006a).
Since independence all the Central Asian
countries apart from Turkmenistan have
seen an increase in the demand for wood
fuel (FAO, 2006a). Primarily due to low
productivity, forest plantations make up
only a small proportion of the total forest
cover in Central Asia. These are mainly
set aside for protective measures rather
than for wood production. Most of the
Central Asian countries depend on
imported wood, although imports have
drastically reduced since the break-up of
the Soviet Union (FAO, 2006a). Although
logging is officially illegal in the majority of
the indigenous forests in Central Asia,
substantial quantities are still removed
The Red List of Trees of Central Asia
(FAO, 2006a). Trees are felled for timber
and, in the case of walnut, to produce
veneer for furniture. The amount of illegal
felling that is currently taking place is not
known.
Non-timber forest products (NTFPs) such
as walnuts, apples and pistachios are an
important source of livelihoods for rural
communities in Central Asia. Collection of
NTFPs ranges from subsistence
harvesting to collection for international
trade with, for example, China or Turkey.
In southern Kyrgyzstan, walnut is the
most important NTFP and can be a major
source of income for the local population,
especially during years of good harvest
(Fisher et al., 2004).
For rural communities the forests also
provide grazing for livestock and the
under-storey of wood pastures is cut for
hay to provide fodder during the winter
months. Although grazing is illegal in the
majority of leskhozes in Kyrgyzstan,
livestock grazing in woodland is very
much the norm (Fisher et al., 2004).
Safarov, 2003; Cornet and Rajapbaev,
2004; IRIN, 2003) all indicate that Central
Asian forests and woodlands are under
severe threat from over-exploitation,
desertification, pests and diseases, overgrazing and fires. A combination of
factors including the cessation of
subsidized timber from the former Soviet
Union, rural poverty, a lack of alternative
energy sources and the lack of
institutional capacity to protect and
regulate forests have all added to the
pressure on vulnerable forests of the
region. The forests and woodlands
growing on the foothills of the Tien Shan,
Palmir-Alai and Kopetdag mountains,
especially those near rural settlements,
are most threatened. This includes the
slow-growing juniper forests of Tajikistan
and Kyrgyzstan, which are threatened by
firewood collection and over-grazing.
Kyrgyzstan, for example, lost some 35%
of its montane juniper in just a few
decades (MEP, 1998). As firewood
becomes increasingly scarce around
settlements, villagers have to go deeper
and deeper into the forest to satisfy their
daily fuel needs.
THREATS TO FORESTS AND
WOODLANDS
The
Global
Forest
Resources
Assessment 2005 (FAO, 2006b) indicates
that the extent of forests and woodlands
in Central Asia has remained relatively
unchanged since 1995. However, the
reliability of the data provided for the
assessment is uncertain owing to the
region’s lack of capacity to monitor and
conduct forest inventories since the
break-up of the Soviet Union. There is
also very little official information on the
actual status of forests, their associated
species and levels of degradation.
A number of reports, national biodiversity
strategies and the experience of regional
experts (MEP, 1998; MNPT, 2002;
Although an important source of income
for rural communities, unsustainable rates
of harvesting of NTFPs such as walnuts
continue to pose a huge threat to the
region’s unique fruit and nut forests. The
threat is further compounded by
unregulated logging, grazing, hay-making
and, more recently, pests such as the
gypsy moth Lymantria dispar. In the JalalAbad province of Kyrgyzstan local
foresters and residents have noticed
marked reductions in the walnut and
apple harvest in recent years (IRIN, 2003).
A biodiversity hotspot report by
Conservation International (CI, 2008)
states that some 90% of fruit and nut
forest habitats have been lost in the last
50 years.
The forests of the Tien Shan and PamirAlai mountains and the floodplain tugai
forests provide crucial environmental
protection and ecosystems services to
the predominately arid Central Asian
region. Their loss and degradation not
only threatens globally unique biodiversity
and rural livelihoods but also endangers
water supply and regulation, essential to
fertile agricultural areas such as the
Fergana Valley and major metropolises in
the region.
METHODOLOGY USED FOR
CONSERVATION STATUS
ASSESSMENT
The IUCN/SSC Global Tree Specialist
Group, in association with the Global
Trees Campaign, uses a number of
approaches to undertake global
assessments of the conservation status
of tree species (Newton and Oldfield,
2008). These include, most importantly,
close collaboration with regional and
international experts in botany and
forestry, as well as extensive literature
reviews and searches on online
taxonomic and herbarium databases,
supported by GIS mapping.
To undertake an assessment of the
conservation status of Central Asian trees
the Global Trees Campaign organized a
workshop in July 2006 to bring together
a range of regional experts from the
Central Asian countries. A total of 25
participants
from
Kyrgyzstan,
Kazakhstan, Tajikistan, Uzbekistan and
the UK attended the workshop in
Bishkek, Kyrgyzstan. Regrettably, the
workshop organizers were unable to
arrange for an expert from Turkmenistan
to attend. Over the 3-day workshop the
participants, through much discussion
and debate, produced a list of nationally
threatened tree species, a candidate list
of globally threatened Central Asian tree
7
The Red List of Trees of Central Asia
species, and a preliminary Red List of
globally threatened trees from Central
Asia using the IUCN Red List categories
and criteria (IUCN, 2001). During the
workshop a map of regional forest cover,
derived from satellite remote sensing
imagery, was used to define the potential
distributional range of selected species.
For this purpose the Moderate Resolution
Imaging Spectroradiometer (MODIS)
Vegetation Continuous Fields (VCF)
product was used (Hansen et al., 2003).
This product depicts the percentage tree
cover at a resolution of 500 m using a
supervised regression tree algorithm. For
each species considered distributional
ranges were derived by exploring the
expert data elicited during the workshop
using ArcView v. 9.1 (ESRI, Redlands,
USA; www.esri.com). Following the
workshop the preliminary Red List was
reviewed and revised with the assistance
of the Red List Unit, IUCN Species
Programme and additional research in
the literature and online databases.
RESULTS OF EVALUATION
Over the course of the 3-day workshop
25 experts from Kyrgyzstan, Kazakhstan,
Tajikistan, Uzbekistan and the UK
evaluated 96 Central Asian tree and
shrub species according to the IUCN Red
List categories and criteria (IUCN, 2001).
Twelve tree and shrub taxa listed in the
Red Data Book of Turkmenistan
(Atamuradov et al., 1999) were not
evaluated as no national experts from
Turkmenistan attended the workshop.
The full Red List of globally threatened
trees from Central Asia with associated
categories and criteria can be found on
page 13. A summary of the results of the
evaluation are in the table below.

Of the 96 taxa evaluated, 44 are
categorized as Critically Endangered,
Endangered or Vulnerable, meaning that
they are threatened with extinction in the
wild according to the IUCN Red List
categories and criteria. A further five taxa
are Near Threatened and 17 are Data
Deficient. Data Deficient taxa are those
taxa that are deemed not to have sufficient
information available to assign a Red List
category. In the current evaluation this is
primarily because of the lack of knowledge
of the conservation status of species
whose distributions extend outside Central
Asia, for example, into Afghanistan or Iran.
In addition, the lack of capacity of scientific
institutions to undertake fieldwork,
particularly since the break-up of the
Soviet Union, has reduced the availability
of up-to-date information. This is especially
pertinent for Kazakhstan, the ninth largest
country in the world.
A high proportion of the threatened taxa
are Critically Endangered, that is, they
face an extremely high risk of extinction
in the wild. Many of these are narrow
endemics, such as Abies semenovii and
Crataegus
knorringiana,
whose
fragmented populations are threatened
by cutting and/or over-grazing. Others,
relatives of domesticated fruit trees and
shrubs such as Pyrus korshinskyi and
Ribes malvifolium, are threatened by
over-harvesting of fruits and collection of
saplings as rootstock for grafting. More
specifically, Calligonum triste is directly
threatened by desertification and soil
salination resulting from the drainage of
the Aral Sea.
A number of the species that are
Endangered or Vulnerable are wild
relatives of domesticated fruit and nut
varieties. This includes wild apricot
Armenica vulgaris (EN), which is
threatened by unsustainable harvesting
and over-collection by national and
international plant-breeding companies.
Two wild apple species, Malus
niedzwetzkyana (EN) and Malus sieversii
(VU), are still found in the fragmented fruit
and nut forests of Central Asia and are
threatened by habitat degradation, mainly
from agricultural development and overgrazing.
A number of species are directly
threatened by over-collection for
firewood. This includes Juniperus
schugnanica (VU), Calligonum calcareum
(CR) and Calligonum paletzkianum (VU).
Populations of these species have all
seen dramatic declines in recent years,
particularly those in the vicinity of rural
settlements.
The experts evaluated both walnut
Juglans regia and pistachio Pistacia vera
as Near Threatened even though recent
paleontological evidence for walnut in the
Fergana Valley (Kyrgyzstan) suggests it
may have an anthropogenic origin, rather
than native (Beer et al., 2007). For walnut,
the experts have taken a precautionary
approach until further evidence becomes
available because of the global
significance of the walnut forests in
Central Asia and their importance as an
international genetic resource.

CURRENT CONSERVATION
MEASURES FOR THREATENED
TREES OF CENTRAL ASIA
As described in the introduction, all five
countries of Central Asia have a longestablished tradition of nature protection
and forest management. This is also true
for scientific research in the biological
sciences and is evident in the extensive
network of botanic gardens, arboretums,
universities and academic research
institutions throughout the region.
However, as previously discussed, the
region has undergone dramatic economic,
social and political transition following
independence from the former Soviet
Union in 1991. This has had a profound
impact on the capacity of forestry, nature
protection and scientific institutions to
survey, manage and monitor forests,
woodlands and threatened species. The
majority of state conservation agencies and
research institutions are severely underresourced and are unable to conduct
baseline surveys, let alone regulate and
manage forest resource use. In turn,
botanic gardens and germplasm banks
lack the staff and basic equipment to
maintain globally important ex situ
collections of threatened trees.
There is immense pressure on Central
Asian forests and woodlands to provide
firewood, timber and NTFPs. State forestry
agencies and protected areas therefore
face huge challenges in the conservation
of threatened trees and the sustainable use
of forest products. These challenges are
exemplified by the 44 globally threatened
tree species, a significant proportion of
which are wild relatives of globally
important fruit crops.
The global importance and plight of the
unique forests and fruit and nut diversity of
Central Asia has recently begun to be
• Archa JUMP Project on the Sustainable Management of Juniper Forests in
Southern Kyrgyzstan (CEC)
• Central Asia Transboundary Biodiversity Project in West Tien Shan (GEF)
• Conservation of Tugai Forests and Strengthening Protected Areas System in the
Amu-Darya Delta of Karakalpakstan (UNDP and GEF)
• Impact of the Transformation Process on Human-environmental Interactions in
Southern Kyrgyzstan (Volkswagen Foundation)
• In-situ Conservation of Kazakhstan’s Mountain Agrobiodiversity (UNDP/GEF)
• Kyrgyz-Swiss Forestry Support Programme (Intercooperation)
• Community Conservation of Globally Important Fruit and Nut Forests in
Kyrgyzstan (FFI)
recognized with a number of internationally
funded projects. Some of these projects
are listed in Box 1.
Although the above projects vary greatly
in scope it is essential that any lessons
learnt, best practice and possible
solutions are disseminated effectively
throughout the region. Not only do the
Central Asian countries share a recent
political legacy, watersheds and mountain
ranges, but they also share many similar
issues and problems regarding nature
conservation, environmental protection,
rural development and the sustainable
use of natural resources.
Case Study: Community Conservation of the Walnut-fruit Forests in Kyrgyzstan
FFI is working with local partners in Kyrgyzstan to improve the conservation of walnutfruit forests by promoting the involvement of local communities in forest management.
Threats to forest integrity include: limited natural regeneration because of grazing
pressure and hay-making within the forest; illegal cutting of trees and collection of
firewood; over-harvesting of fruits and nuts; pests (such as gypsy moth) and disease.
In recent times, local people have had little opportunity to engage in forest
management and planning, although they do have access to forest resources
through the leasing of forest plots. These fruit and nut forests are a vital resource for
local people, providing fuelwood, food, fodder and grazing for livestock, as well as
an important income from the walnut harvest.
The project is initially working in Kara Alma, bringing together community
representatives, the local forest service and other stakeholders for open discussions
on key issues, resulting in a collaborative conservation management plan for the
sustainable use of the forest. In addition, following a participatory needs assessment,
training and essential equipment are being provided to the local forest service to
increase their capacity to work with local communities to protect and manage the
forest. Through the provision of small grants and associated training, local people
are being supported to adopt environmentally sustainable livelihood options to reduce
socio-economic pressures on the forest. These small-scale income generation
initiatives have included bee keeping, fruit preservation, and various small workshops.
Liesje Birchenough, Eurasia Programme Manager, Fauna & Flora International

PRIORITY NEEDS FOR ACTION
The forests of Central Asia, with their
incredibly rich diversity of fruit and nut trees,
are of global significance. The conservation
of this unique inheritance is paramount, not
only for the region but for the whole
international community. It is therefore
imperative that the international community
provides the necessary financial resources,
investment and training to build the
capacity of scientific institutions, nature
conservation and forestry agencies,
botanic gardens and germplasm banks to
manage and conserve this unique heritage
effectively.
The region’s state forestry agencies and
protected areas network require substantial
investment and capacity building. With so
many challenges faced by these agencies,
training in the development of participatory
forest management plans, local community
engagement, rural development and
natural resource management is urgently
needed. Many of the state agencies lack
basic equipment and infrastructure such as
uniforms,
horses
or
vehicles,
communication equipment and ranger
posts. In order to alleviate the immediate
pressures on forests from firewood
collection and illegal logging, pilot projects
that provide alternative sources of energy
to villagers should be trialled, assessed and
rolled out.
A review of the status of the region’s
botanic gardens, gene bank facilities and
ex situ tree collections needs to be
undertaken. This should be coupled with a
review of the ex situ collections held
outside the region. Once the state of these
institutions is known a programme of
institutional capacity building, possibly with
the formation of a regional network of
ex situ conservation facilities, should be
initiated. Representatives of the 44
threatened tree species not yet conserved
10
in ex situ collections should be established
as soon as possible to act as an insurance
policy against extinctions in the wild.
National plant genetic resource authorities
should be provided with the necessary
legal and policy training to establish multilateral agreements for the exchange and
utilisation of plant genetic resources. Once
established, these agreements could be a
mechanism to ensure long-term funding for
the conservation of globally important
genetic resources. It is a sad irony that the
progenitor of the domesticated apple,
Malus sieversii, is threatened by extinction
in its natural environment, whilst the export
value of apples from the top ten appleproducing countries is over US$3 billion a
year (FAO, 2008). More poignantly, Malus
sieversii germplasm collected in the 1990s
from Kazakhstan is currently being used by
the USDA Agricultural Research Service to
improve disease resistance in current apple
cultivars (Forsline et al., 2003). So far,
researchers have discovered Malus
sieversii samples that show resistance to
apple scab, fire blight, drought and
numerous soil pathogens (Pons, 2006).
These research findings once again
highlight the global importance of
conserving the wild relatives of
domesticated fruit and nut trees.
Twenty-three of the trees and shrubs
evaluated are Critically Endangered.
Species recovery plans using both in situ
and ex situ methods need to be developed
and implemented urgently. Close
collaboration between different agencies in
neighbouring countries may be required for
transboundary species.
Eighteen of the species are Data Deficient
(DD). For a number of species this is
because of scientific institutions’ lack of
capacity to conduct basic surveys. A
number of potentially threatened species
have not been surveyed since before
Soviet times and their current conservation
status is not known. Other DD species
require collaboration with experts in China,
Afghanistan, Iran and Pakistan in order to
establish their conservation status.

ANNEX 1
IUCN RED LIST CATEGORIES AND CRITERIA
EXTINCT (EX)
A taxon is Extinct when there is no reasonable doubt that the last
individual has died. A taxon is presumed Extinct when exhaustive
surveys in known and/or expected habitat, at appropriate times
(diurnal, seasonal, annual), throughout its historic range have failed
to record an individual. Surveys should be over a time-frame
appropriate to the taxon’s life cycle and life form.
EXTINCT IN THE WILD (EW)
A taxon is Extinct in the Wild when it is known only to survive in
cultivation, in captivity or as a naturalized population (or populations)
well outside the past range. A taxon is presumed Extinct in the Wild
when exhaustive surveys in known and/or expected habitat, at
appropriate times (diurnal, seasonal, annual), throughout its historic
range have failed to record an individual. Surveys should be over a
time-frame appropriate to the taxon’s life cycle and life form.
DATA DEFICIENT (DD)
A taxon is Data Deficient when there is inadequate information to
make a direct, or indirect, assessment of its risk of extinction based
on its distribution and/or population status. A taxon in this category
may be well studied, and its biology well known, but appropriate
data on abundance and/or distribution are lacking. Data Deficient is
therefore not a category of threat. Listing of taxa in this category
indicates that more information is required and acknowledges the
possibility that future research will show that threatened classification
is appropriate. It is important to make positive use of whatever data
are available. In many cases great care should be exercised in
choosing between DD and a threatened status. If the range of a
taxon is suspected to be relatively circumscribed, and a considerable
period of time has elapsed since the last record of the taxon,
threatened status may well be justified.
NOT EVALUATED (NE)
A taxon is Not Evaluated when it is has not yet been evaluated
against the criteria.
CRITICALLY ENDANGERED (CR)
A taxon is Critically Endangered when the best available evidence
indicates that it meets any of the criteria A to E for Critically
Endangered (see Section V), and it is therefore considered to be
facing an extremely high risk of extinction in the wild.
THE CRITERIA FOR CRITICALLY ENDANGERED,
ENDANGERED AND VULNERABLE
ENDANGERED (EN)
A taxon is Endangered when the best available evidence indicates
that it meets any of the criteria A to E for Endangered (see Section
V), and it is therefore considered to be facing a very high risk of
extinction in the wild.
CRITICALLY ENDANGERED (CR)
A taxon is Critically Endangered when the best available evidence
indicates that it meets any of the following criteria (A to E), and it is
therefore considered to be facing an extremely high risk of extinction
in the wild:
VULNERABLE (VU)
A taxon is Vulnerable when the best available evidence indicates that
it meets any of the criteria A to E for Vulnerable (see Section V), and
it is therefore considered to be facing a high risk of extinction in
the wild.
A. Reduction in population size based on any of the following:
1. An observed, estimated, inferred or suspected population size
reduction of ≥90% over the last 10 years or three generations,

(c) a decline in area of occupancy, extent of occurrence
and/or quality of habitat
(d) actual or potential levels of exploitation
(e) the effects of introduced taxa, hybridization, pathogens,
pollutants, competitors or parasites.
NEAR THREATENED (NT)
A taxon is Near Threatened when it has been evaluated against the
criteria but does not qualify for Critically Endangered, Endangered or
Vulnerable now, but is close to qualifying for or is likely to qualify for
a threatened category in the near future.
LEAST CONCERN (LC)
A taxon is Least Concern when it has been evaluated against the
criteria and does not qualify for Critically Endangered, Endangered,
Vulnerable or Near Threatened. Widespread and abundant taxa are
included in this category.
