1 Introduction
Agarwood is an aromatic resin produced in the stems of tropical trees within the genera Aquilaria and Gyrinops (Thymelaeaceae). Agarwood is traded under various names (gaharu, agarwood, aloeswood, eaglewood) and is used for incense, (Qi and He 2005, Gianno and Kochumman 1981), perfumes (Chaudhari 1993), medicines, aromatherapy (Barden et al. 2000, LaFrankie 1994), and religious ceremonies (Qi and He 2005, LaFrankie 1994). Agarwood is highly valued by consumers in Asia and the Middle-East, including countries such as Saudi Arabia, the United Arab Emirates, Hong Kong, Japan and Taiwan for its distinctive fragrance. Indonesia and Malaysia were the leading exporter of agarwood from 1995 to 1997 with Singapore the main reexporter in the same year (Barden et al. 2000). However, these authors also reported that little or no information was available from other agarwood producing or consuming countries. Although agarwood species (Aquilaria and Gyrinops) are the focus of increasing conservation concern, information on their status and distribution is lacking in most countries in Southeast Asia including Papua New Guinea. Awareness and training programmes are required in many countries to assist local communities in harvesting agarwood on a sustainable manner and participate in its cultivation. The promotion and development of agarwood plantations would be an initiative to preserve natural Aquilaria and Gyrinops trees, as well as satisfy the high demand for agarwood in world market. To achieve this goal, greater research into propagation and silviculture is needed to safeguard the genetic resources from excessive exploitation. Agarwood is classified as a non-wood forest product primarily from species in the genus Aquilaria (Thymelaeaceae). However, other genera such as Gyrinops and Gonystylus also contribute to the international agarwood supply. Agarwood is defined in this review as the fragrant resin produced in all species from the genera Aquilaria and Gyrinops. Agarwood provides distinctive ingredients in medicinal, aromatic and religious ceremonies and rituals in many east Asian and Arab countries (Chaudhari 1993, Barden et al. 2000, Than 2007). It is sold in the form of woodchips, wood pieces, powder, dust, oil, incense ingredients and perfume for several thousand US dollars per kilogram (LaFrankie 1994, Barden et al. 2000, Gunn et al. 2004a, Compton 2007). With such a high economic value, the rate of agarwood exploitation from natural populations has increased to meet the demand. This has resulted in the degradation of wild sources of Aquilaria in south-east Asian countries (Barden et al. 2000) including West Papua and Papua New Guinea (PNG) (Jensen 2007). Consequently, all Aquilaria and other agarwood producing species are now listed under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II (refer to Annex 2). CITES emerged in 1973 to address the threat posed by unsustainable international trade in wildlife and the current Appendix II regulates international trade through permits (Mandang and Wiyono 2002, CITES 2003, Compton 2007). The main purpose of listing agarwood species in Appendix II of the Convention (CITES) was to control and verify agarwood international trade for both trade and consumer countries on a legal and sustainable manner (Compton 2004). While Compton (2007) recognises that CITES is one of the worlds most influential agreements on species conservation, he indicates that implementing trade permits for agarwood is challenging and more awareness and
training by CITES Management Authority is required in each agarwood producing country. The degradation of natural agarwood sources has led to an irregular product supply and quality. The cultivation of agarwood can potentially (i) increase the market supply for agarwood, (ii) provide a sustainable income source for local producers and (iii) reduce the harvest pressures on natural stands. Despite records of successful cultivation reported in Malaysia (Lok and Ahmed Zahaidi 1996) and Vietnam (Nakashima and Mai Thanh Thi 2005) no documented domestication activities for any agarwood species has been found for this review. All documented plantings were based on seeds or wildings collected randomly from natural populations. Initiating domestication through the assessment of natural variation in characters important for cultivation can help to optimise the quality and production of agarwood from planted sources. Domestication activities are also dependant upon fundamental understanding of reproductive and seed biology, vegetative propagation (cuttings, grafting, tissue culture) and silvicultural management.
directly from the tree, each containing two seeds (PROSEA 2005). The matured seed of A. crassna is also blackish with an oval shape and a diameter of 0.5-0.8 cm. (Fig. 1) (Hoang and Nguyen 2002). Based on the similarities in morphological appearance between Aquilaria species (Thawatchai 2007), there is need for further investigation of floral structure to help distinguish species among the two genera (Aquilaria and Gyrinops). The taxonomy of Gyrinops species in PNG and West Papua is poorly known (Bangai 2007, Braden et al. 2000). Differentiating Gyrinops from Aquilaria in PNG is based on the number of stamens, with Aquilaria possessing 10 and Gyrinops 5 (Gunn et al. 2004a, Bangai 2007). The first Gyrinops species was confirmed in PNG in 1997. There are two main species of Gyrinops in PNG. G. ledermanii is found in the northern region and G. caudata is found in the southern region of PNG. (Gunn et al. 2004a, Bangai 2007). There is however, very little morphological difference between these species. At maturity G. ledermanii is a medium size tree of 20-30 m in height and diameter at breast height of 19-27 cm. G.caudata is a large tree of 35 cm in height and 20-65 cm in diameter (Gunn et al. 2004a, Bangai 2007). Leaves of both species have an alternate arrangement and the underside is pubescent while the upper side is glabrous. The inflorences are elliptic and axillary umbel containing flowers of 1-2 cm long, yellowish green or white. The hairy juvenile fruit is green, oval shaped with a pointed end, containing two seeds per fruit. Matured seeds are blackish in colour with a pointed end (Kipiro pers. comm. 2008).

2.1 Biogeography
The various species of Aquilaria and Gyrinops are well distributed in the tropics and subtropics in south-east Asia, mainly in India, Bhutan, Peninsular Malaysia, Indonesia, Myanma, Cambodia, Vietnam, China, Thailand, Lao Peoples Democratic Republic, and New Guinea (Fig. 2) (Barden et al. 2000). The genera is well adapted to various natural habitats from lowland rainforest to montane forests at an altitude of 800-1500 m.a.s.l (CITES 2004, Thawatachai 2007).
Figure 2. Distribution map of agarwood and importing/re-exporting countries (information source: Barden et al. (2000). The genus Aquilaria consists of species that are adapted to rocky, sandy or calcareous, well-drained slopes and ridges and near swamps (Barden et al. 2000). In PNG, A. falaria and G.caudata occurs on ridges and lowland rainforest including areas adjacent to swamps in the southern region (Kipiro pers. comm. 2008). Soehartono and Newton (2000) reported that reliable distribution information is lacking in many countries like Indonesia, Malaysia and Thailand due to difficult access to National Herbarium databases in south-east Asia, and rudimentary inventory and trading pattern surveys. Approximately 15-20 agarwood producing species are well distributed in south and south-east Asia to the Pacific (Barden et al. 2000, Donovan and Puri 2004, Thawatachai 2007). The number of agarwood producing species may be expected to increase if more inventories are conducted in countries like PNG (Gunn et al. 2004a, Bangai 2007). Like other tropical tree species, they can be found in single dominant stands, but are predominantly scattered throughout the habitat (Barden et al. 2000). Nevertheless, there is a need for more research regarding the distribution pattern in most countries to understand the magnitude of its limits and occurrences. 3 Overexploitation of agarwood
Excessive exploitation of natural sources of agarwood has been reported in Laos People Democratic Republic (Jensen 2007) China (Wang 2007), Myanmar (Than 2007) and Indonesia (Newton and Soehartono 2001). In Malaysia, A. malacensis, the main agarwood producing species is classified as endangered resulting from overexploitation of its natural populations for the international trade (Ibrahim et al. 2007). The depletion of agarwood populations in India was reported as early as 1907 with no significant amount of agarwood available. In response to this, agarwood
plantations were established in India in 1930s and 1940s, primarily by private growers across Assam (Quavi 2007). Indonesia was a major exporter of high quality agarwood (A. malacensis) but there is little knowledge on the extent and status of remnant wild stands (Soehartono 2003). Most remaining Aquilaria stands are decreasing rapidly particularly in the forests of Sumatra, Kalimantan and Borneo due to excessive exploitation and illegal logging operations, gold mining operations and clearing of huge forest areas for agricultural purposes (Barden et al. 2000, Soehartono 2003, CITES 2004, Donovan and Puri, 2004). PNG has been regarded as one of the last significant sources of natural agarwood. It is likely that illegal harvesting and trading of agarwood occurred well before Gyrinops ledermanii was confirmed in 1997 as an agarwood producing species (Gunn et al. 2004a; Bangai 2007). Illegal harvesting is still increasing, mostly in the northern region of PNG (Gunn et al. 2004a; Bangai 2007). Barden et al. (2000) reported that the illegal trade of agarwood from PNG occurred primarily through the township of Vanimo to the Irian Jaya Province of Indonesia. Unsustainable exploitation of agarwood across all producing countries has prompted CITES to list Aquilaria and Gyrinops species (or other agarwood-producing species yet to be described in many countries) on the CITES Appendix II. This listing requires regulation of international trade of agarwood specimens under legal instruments. However, the effective implementation of these regulatory guidelines can be problematic (Compton 2007). Therefore initiatives such as establishing cultivated agarwood resources can help to satisfy international demand and relieve pressure on natural sources.
Figure 3: Grades of agarwood harvested from Sarawak (Malaysia). Grade A has the darkest colour, highest concentration of resin and highest price. (Photo: J. Dawend 2007) Masataka (2007) and Compton (2004) indicate that a rise in fake agarwood products such as wood impregnated with artificial oil (Black Magic Wood or BMW) might be expected as the global demand increases and supply decreases. Such products are also traded under CITES regulation (Masataka 2007) because the base wood originated from Aquilaria or Gyrinops species. Masataka (2007) asserts that CITES needs to ensure Aquilaria-based fake products are certified under permits distinct from the traditional agarwood products to maintain consumer confidence in product quality.
(Donovan and Puri 2004). However, these visual indicators can be subtle and difficult to detect in very large trees and unskilled harvesters of agarwood may indiscriminately fell trees in search of the valuable resinous wood.
4 Cultivation
The preservation of natural Aquilaria populations to increase the supply of agarwood in the world market can be assisted through cultivation of Aquilaria species. In recognition of this, agarwood plantations have been established in Indonesia, Cambodia, Thailand, Vietnam and other countries (Fig. 4) (Barden et al. 2000). Cultivation of agarwood was also reported in Malaysia (Lok and Ahmed Zahaidi 1996, Lok and Chang 1999). Given the low level of documentation the present status of the plantation resource in these countries is unknown. Agarwood cultivation in Vietnam is based on seedlings collected from the wild with many plantings now being used as seed stands to support the establishment of further plantations (Nakashima and Mai Thanh Thi 2005). In Bangladesh the earliest record of agarwood cultivation was in 1925 with artificial inoculations on remaining trees conducted 55 years later (Rahman and Basak 1980, Rahman and Khisa 1984). The findings from these early inoculations studies were not published. Even though plantations were reported to exist in these countries no written reports on propagation, silviculture, production or sales of agarwood from these plantations could be located.

Vegetative propagation
Vegetative propagation and clonal selection offers a means to enhance yield and quality of forest products from commercial planting in the tropics (Leakey, 1987). The domestication of forest trees through breeding commenced in the 1950s with Pinus specie (Barnes and Simons 1994). Ever since there was an ultimate interest for higher yields and better products has come to the domestication of forest trees. A number of approaches were applied including grafting, stem cuttings, hardwood cuttings marcotting (air-layering), suckering and in vitro techniques (meristem proliferation, organogenesis and somatic embryogenesis) (Macdonald 1986, Leakey 1985, Hartmann and Kester 1983). Apart from these propagation techniques stem cuttings is becoming a common propagation method in forestry and agroforestry (Leakey et al. 1990). However, this can be costly in developing countries with the use of electricity and a piped water supply. This relates to mist propagation systems for research and largescale commercial projects. The stem cuttings require an appropriate environment for root initiation that would minimize physiological stress in the cuttings (Leakey et al. 1987). In a broader term, providing shade to lower the air temperature, providing high humidity, and reduce transpiration losses. Importantly, ensuring the vapour pressure of the atmosphere surrounding the cutting is maintained close to that in the intercellular space of its leaf (Leakey et al. 1990). Many propagation systems were used in commercial horticulture. These are either based on spraying mist, fogging or enclosing the cutting in polythene. However, recent improvement on the design of non-mist propagators for use with wide range of timber and multi-purpose tree species in both tropical moist forest and semi-arid area being so success (Leaky and Longman 1988).

In forestry, vegetative propagation is used for the production of fast growing trees that produce high quality timber. Clonal approach to plantation improvement through cutting propagation of plus trees plays an important role in increasing productivity, uniformity and quality in forest plantations. This propagation methods (stem cuttings) plays a vital role in capturing existing genetic traits that can be used a basis of a genetic variety or cultivar alternative for tree improvement programmes.
Stock plant physiology will be important to the successful propagation of cuttings and this can be controlled, to some degree, by stock plant management (Hoad and Leakey 1994). The physiology of the stock plant will be influenced by the plant genotype and environmental conditions such as water, temperature, light, carbon dioxide and nutrition (Hartmann et al. 2002). Therefore a basic understanding of stock plant physiology and its management to maintain its health, vigour and longevity will help to maximise adventitious root formation in its cuttings. 5.1.2.1 Water Stocks plants under extreme conditions such as drought may have an effect on the rooting ability of its cuttings due to moisture limitations (Hartmann et al. 2002). Therefore it is crucial to take cutting materials from stock plants that have little to no drought stress, which can be ensured by regular stockplant irrigation. Collection of cuttings in the early morning when plant material is in a turgid condition is also recommended to minimise any local water deficits (Leakey et al. 1992). Adventitious root induction is substantially reduced in drought stressed cuttings compared with those with adequate cell water potential (Hartmann et al. 2002). Lebude et al. (2004) reported that loblolly pine (Pinus taeda L.) optimum cutting results would be achieved with moderate cutting water potentials (-0.5 to -1.2 MPa) during 4-5weeks of the rooting period. In plants under drought, stomata are closed limiting the exchange of gases as well as the reduction of photosynthesis, which can continue in the cuttings once severed thus limiting carbohydrate availability for adventitious root induction and growth. 5.1.2.2 Temperature Little is known about the effect of temperature on stock plants (Hartmann et al. 2002). But, providing shade to nursery plants or planting nitrogen-fixing species to provide shade for hedge plants must be considered to prevent dehydration from extreme temperatures. In general, temperature exceeding 60 C will kill the roots of all plants and above 40 C reduces the root growth for most species (Handreck and Black 1984). The dead roots may provide a favourable condition for pathogens to invade the stockplant. The optimum temperature in the medium for plant growth (roots and shoots) should be in the range 15-30 C (Handreck and Black 1984). This range in temperature may not be suitable for most plants because they vary with plant species and variety, moisture in the medium, air temperature, light intensity and nutrient content in the media or soil. 5.1.2.3 Preseverance of stockplant (Light and Nutrients) Nutrients and light is considered to be the main effects as preconditioning agents on rooting ability. As study showed that in T.scleroxylon the interactive effects of nutrients and quantity and quality of light had an effect on photosynthesis and the carbohydrate status of cuttings (Leaky 2004). It is understood that active photosynthesis is associated with best rooting. This may link to amount of low irradiance and low red-to-far-red ratios that believe to independently enhance rooting ability (Leakey 1983).
12
Cuttings taken from under-shade Eucalyptus grandis stockplant tends to have longer internodes, larger leaf area, codominance between shoots lower rates of perseverance net photosynthesis, lower chlorophyll concentration, but higher rates of net photosynthesis per unit of chlorophyll (Leakey 2004). These physiological changes thus relate to shoots response to its surrounding resulting in the differences in stem and leaf morphology. Light duration (photoperiod) and spectral quality (wave length) can influence the stock plant condition and subsequent rooting of cutting (Felker 2008, Hartmann et al. 2002). Therefore managing light for stock plants at the nurseries would be critical for the success of rot cuttings. 5.1.2.4 CO2 Level of carbon dioxide (CO2) in the propagator (non-mist propagator) can be reduced during propagation, limiting photosynthesis and growth in the cuttings (Hartmann et al. 2002). This can happen if the media used is saturated, in which no exchange of gases between the roots and the atmosphere. The plant roots can eventually die, as they no able to effectively respire in the medium. It was reported that photosynthesise could be also limited to low daytime CO2 concentrations in the propagator (Leaky et al. 1990). Thus further research in future can experiment on enhancing CO2 diffusion into the propagator for successful rooting of various tree species.
13
year cuttings are collected. This reflects on the physiology of the stock plant and environmental condition to determine the optimum rooting success.
instance, clones of T. sceroxylon, which appeared to have different dose-response curves, all rooted equally well at 40 g auxin per cutting (Dick et al. 2004, Leakey 2004). This demonstrate that cuttings of various tree species can response differently of auxin types and concentrations, so finding out the optimum auxin concentration for important tree species would be research worth for latter mass propagation for further research projects or commercial scale planting programmes.
15
Therefore balancing photosynthesis and transpiration is crucial for cuttings in the propagation environment. Water loss from a cutting can be tempered by placing it within a high humidity propagator so its leaf area is an important character that influences the balance between photosynthesis and transpiration. In considering this fact, leaf has to be reduced by trimming to give an optimum balance (Longman and Leaky 1995). This would allow the cutting to quickly root and develop a sink for assimilates in the propagator (Corress et al. 2005, Leakey 2004). The trimming off leaf will very much depend on the size that can be varied among species. Cuttings with excessive leaf frequently loss water and come under stress, therefore closing their stomata and limiting their capacity to photosynthesize. The number of stomata on a cutting will be directly proportional to its leaf surface area and therefore leaf area will influence its potential water loss during photosynthesis. Leaf area is a vital variable in relation to level of irradiance in the propagation environment.
5.1.10
The differences in temperature and light-intensity in a propagation environment can affect rooting success. Test conducted in ITE glasshouses reported an air temperature of 20C while in non-mist propagators rose to a mid-day peak about 34 C during bright, sunny, mid-summer weather. This rise temperature was associated with a decrease in relative humidity from about 95% to about 75% (Leakey et al. 1990). The authors further stated that this substantial increase in the saturation vapour pressure deficit (SVPD) of air from 0.02kPa to 1.37 kPa. It is therefore so important to keep the lid of the non-mist propagator tightly closed at all times. By doing so, may decrease in relative humidity if open up to five minutes at midday (Leakey et al. 1990). However, the relative humidity can increase rapidly if the lid is closed back. The increase in temperature of cutting medium can also aid in callus formation and development of cutting. Many temperate species will root rapidly when the medium is held at 27-30C while tropical plants is at 24-27C (Handreck and Black 1984). For instance, study on cutting medium of Schlumbergera Russian Dancer indicated that optimum temperature for root development was between 21.3C and 24.7C, whereas increasing temperature above 24.7C would promote bud growth to occur before roots were developed (Kristiansen et al. 2005). Controlling the temperature in a propagator 16
is very important for the induction of root, shoot development and maintaining humidity to maximise overall rooting capacity.
5.1.11
There are two source of variation in stockplants that are influential by the stockplant environment. The with-in shoot factors and between-shoots factors (Leakey 2004). There are numerous variations with-in a shoot which is associated with the age of the shoot as it develops. For instance, age of leaf, leaf water potential, leaf carbon balance, leaf senescence, internode length, internode diameter, stem lignification, nutrient and stem carbohydrates content, and respiration (Leaky 2004, Hartmann et al. 2002). These variables can have effect of the rooting ability therefore physiological and morphological status of a shoot must be considered prior to setting cuttings. For example, most influential factor on rooting ability was found to be between cutting length and node position with-in shoot variation (Leakey et al. 1982). Sprouting shoots from a cut back stockplant may vary in between-shoot factors. It was reported that most rooting success was from upper shoots than those below from a cutback stockplant (Leaky 2004). Nevertheless, the lower shoots can be reoriented or apply pruning to expose these shoots to light so rooting success can be achieved same as the upper shoots. It is therefore very important to be aware of the morphological and physiological variation with-in or between shoots in order to achieve higher percentage rooting.
5.1.12
Unsuccessful rooting
There are numerous causes that can cause the cuttings not to root and must pay attention to. Some of these could be leaf symptoms (leaf decolourisation, leaf portion attack by insects, and showing sign of wilting) that must be avoided during material collection. As reported by Leakey (2004) that signs of leaves dying were attributed to leaf abscission which associated to water stress, photoinhibition, anoxia and negative carbon balance. The cuttings fail to root would obvious die or rot. It is ideally important to be aware of these aspects to prevent unsuccessful rooting of cuttings.
5.1.13
There could be very limited research on the vegetative propagation of genera Aquilaria and Gyrinops. As very little information were retrieved for this review. A report from Vietnam by Koskela et al. (2002) stated that A. crassna had showed a rooting success of 90%, with a mean of 10.9 roots per cutting and 2.9 cm in length. However, details on stockplant management, cutting origin and environment, temperature and light effects on cuttings, cutting length and other variables were not reported. A study of stem cuttings of Gyrinops ledermanii was conducted at the PNG Forest Research Institute (PNGFRI) recently which reported that Gyrinops can be propagated easily by stem cuttings (Gunn et al. 2004b). Further study had revealed 17
that adventitious roots were produced within 6-7 weeks with 4-5 roots per cutting and root length of 1-10 cm (Lata 2006, unpublished).
Figure 5. Gyrinops ledermanii root cuttings 6-7weeks and a month old clones. Photo by Lata A. (2006) Furthermore, cuttings treated with 0.8 mg/L IBA produced roots more rapidly than those treated with 0.3 mg/L IBA. The overall rooting success of 0.8 mg/L IBA treated cuttings was 78% while those treated with 0.3 mg/L IBA was 58%. Rooting percentage was greater in coarse sand (72.8%), fine sand (35%) and forest soil (15%) after 6 weeks under mist propagation (Lata 2006, unpublished). Rooted cuttings produced an average of 2 pairs of leaves and fibrous root system 4-weeks after transplanting into pots (Fig. 5). These studies indicate that Aquilaria and Gyrinops species can produce adventitious roots as stem cutting, but more research is needed to optimise the management and physiology of the stock plant (ortet), the morphology of the cutting and the environmental conditions during propagation. 5.1.13.1 Stockplant management of Gyrinops PNGFRI The potted plants of Gyrinops ledermanii consisting of 15 plus families were kept in a transparent roof shed. Slow release fertilizer (osmocote) was applied quarterly or as required. The plants were cut back when the plants were more than 45 cm to promote new shoots for cutting experiments. The lower bushy branches were also pruned regularly to allow light penetration and water to reach the potting media and not prevented by the leaves. It took 5-6 months to have a new shoot ready to take cutting materials from. Plants were watered manually twice a day during dry season and once a day during wet season. 5.1.13.2 Cutting variables and propagation environment The variables being investigated in this trial of Gyrinops stem cuttings were cutting medium and IBA concentration to examine the end result of rooting percentages to quantify on the variables being tested. This was just a beginning therefore more variables just as cutting length, leaf area, branch or shoot position, different auxin application, various medium, cutting origin and environment, temperature and light effect on cuttings and genetic variation have to be statistically investigated given the 15 families being propagated for research purposes. As these results may seem to be promising, further research is still required to cover all the points being discussed in section 5 of this review to fully understand all the aspects of propagating Aquilaria or Gyrionops species vegetatively by means of stem
18
cuttings for further research trials or demonstrations plots to initiate the domestication process of this valuable tree species.
Conclusion
The genus Aquilaria (Thymelaeceae) is well known for the production of the highly valued agarwood. The wild sources of many Aquilaria species are decreasing rapidly and becoming endangered through uncontrolled harvesting and discriminate felling of natural population. This may lead to local scarcity of these tree species in some of the agarwood producing countries. As a consequence, there is increasing concern that the natural stocks of Aquilaria trees are not sufficient to meet the international demand for agarwood. Therefore, there is a need for domestication and cultivation of this tree species to relieve pressure on the harvest of natural population. Efforts to domesticate and cultivate agarwood are dependent upon knowledge related to seed biology and vegetative propagation. Like other tropical trees, Aquilaria seed supply from the wild is limited for planting and research programs. Vegetative propagation through stem cuttings may therefore be appropriate to accelerate the establishment of the planting stocks, thereby promoting their conservation and sustaining the production of agarwood. It is therefore worthwhile to undertake applied scientific research to determine the amenability of Aquilaria species to vegetative propagation and techniques to optimise its success.

Annex 2: Definition of CITES Appendices I, II and III CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement between Governments purposely to set measures in controlling the international trade in specimens of wild animals and plants does not threaten their existence or survival (Compton 2004). Appendices I, II and III to the Convention are lists of species that are protection from over-exploitation by issue of permits to eligible to trade the species. Threatened flora or fauna may be added or eliminated from Appendix I and II, or moved between them, by the discretion of the Parties at their Conventional meetings. In comparison, species in Appendix III may be added or eliminated at any time by the any Party (Compton 2004). As report by Compton 2004, a total of 25 000 plant species and 5000 animal species were listed by the Convention as follows: Appendix I: about 6oo animal species and 300 plant species; Appendix II: about 1400 animals and 25 000 plant species; and Appendix III: about 270 animal species and 30 plant species.
Appendix 1 comprised CITES most listed endangered animals and plants. These are threatened with extinction due to overexploitation that is prohibited from International commercial trade in specimens of these species. They can be only allowed under exceptional circumstances, for instance, for scientific research which may be authorised by the granting of both an export permit and an import permit. Appendix II lists of species not necessarily threatened with extinction but are likely to there should be control measures in placed. This involves species that are said to look-alike species in terms of specimens in trade similar to most species listed for conservation reasons. Specimens of species in this Appendix when traded internationally have to be granted and export permit or re-export certificate; no import is permitted. But, the granting of permit to relevant authorities depends of the satisfactory and conditions that are met to ensure there is no threat to the existence of the species in the natural habitat. Appendix III are lists of fauna and flora species already traded but need assistance from Party member countries to prevent unsustainable or illegal exploitations.
