    Executive Summary

    Orchids are perennial or rarely annual, epiphytic, terrestrial or lithophytic herbs with root

    which have multi-layered spongy tissue. Orchids are notably diversified in the moist tropics

    of both hemispheres in which majority are epiphytes in forests. In Nepal 363 species of

    orchids are organized into 97 genera.

    Orchids fall under CITES II category though collection and trade of orchids does not fall

    under the jurisdiction of CITES or any existing legislation. Habitat loss, forest destruction and

    degradation and over exploitation has posed threats to the conservation of orchids in Nepal.

    Due to the notification on the gazette, some rare and endangered orchid species are in

    threat of over exploitation from their natural habitats for trade.

    Enumeration of orchid species, their status, hotspot mapping and the species that are in

    trade has not been assessed to till date in Rolpa district. In the same time, District Forest

    Office Rolpa needed a measurement of orchid stock for releasing permit issue.

    Systematic investigation of orchids should be undertaken for the complete indexing of the

    orchids and contributing to a red data book regarding the threatened and endangered

    species. Orchid reserves in orchid hotspots should be established for the preservation and

    regeneration of orchids. The collection of wild species of orchids for commercialization

    should be banned and the rare and endangered species should be introduced in Botanic

    gardens. Systematic research on propagation technique such as tissue culture should be

    promoted for the commercially valuable orchids.

    A total of 36 species of both terrestrial and epiphytic orchids were identified in the studied 17VDCs of Rolpa district. Orchid habitat hotspots and host plants were identified within the

    community forests as well as government managed forests at the altitudes between 1000-

    2300m in humid and moisture rich mixed broadleaved forest of the surveyed VDCs.

    Of the total broadleaved forest area of the surveyed VDCs, it is assumed that only 40% of

    the total broadleaved forest area host orchids. Total stock of D. denudans was recorded

    highest in Uwa VDC with 11018.08 kg followed by Seram VDC with the stock of 9982.57 kg

    and Liwang VDC with total stock of 6057.35 kg. Similarly, total stock of D. eriiflorumwas

    recorded highest in Seram, Siuri and Jaimakasala with the total stock of 22750.01 kg,

    7039.67 kg and 4933.46 kg respectively. However, total stock of orchids comprises of all

    size / age classes and cannot be harvested in totality.

    CHAPTER ONE

    1.1 Introduction

    Orchids (Nepali name: Sunakhari, Sungava, Jivanti; Family: Orchidaceae) is one of the

    largest family of flowering plants comprising more than 17000 species in the world. In Nepal363 species of orchids are organized into 97 genera (Rajbhandari and Bhattarai, 2001).

    Orchids are notably diversified in the moist tropics of both hemispheres in which majority are

    epiphytes in forests. Most of the temperate and almost all of the alpine genera are terrestrial,

    while some are lithophytes.

    The first systematic orchids collection in Nepal was done by Hamilton in 1802 and Wallich in

    1820 mainly from Kathmandu valley (Rajbhandari, 1976) and their collections were studied

    by David Don in 1825-26. Hara et al. (1978), Banerji (1978) and Banerji and Pradhan (1984)

    have given list and descriptions of orchids of Nepal. Till then, several orchids new to Nepal

    have been reported by Bajracharya et al. (1993), Bania et al. (1993), Cribb and Tang (1983),DuPuy and Cribb (1988), Pearce and Cribb (1996), Rajbhandari and Bhattarai (1995-96),

    Rajbhandari et al. (1997, 1998), Shakya (2000), Shakya and Bania (1998); Shakya and

    Chaudhary (1999), Wood (1986, 1989).

    Orchids are perennial or rarely annual, epiphytic, terrestrial or lithophytic herbs with root

    which have multi-layered spongy tissue. They are capable of absorbing and storing

    considerable quantity of moisture. In terrestrial species, the roots are often swollen into

    tubers or stems from corms or rhizomes. Stems of epiphytic species are often thickened to

    form a pseudo-bulb with adventitious roots. Two types of growth habit are found in orchids:

    Sympodial and monopodial. In sympodial plants the shoots are clustered together or spreadout on a long rhizome and new shoots may arise from any part of the older shoots where

    there is an axillary bud. In monopodial plants the shoots have the potential for indefinite

    apical growth.

    Habitat loss, forest destruction and degradation and over exploitation has posed threats to

    the conservation of orchids in Nepal. Detailed studies to understand the conservation status

    of orchids of Nepal are still lacking. It is considered that many orchid species of Nepal are at

    the threatened stage now.

    Up to the fiscal year 2063/064; 2353kg of orchids were released from Rolpa district thereby

    generating the revenue of Rs.7459 (DFO Rolpa, 2008). But, the enumeration of orchid

    species, their status, hotspot mapping and the species that are in trade has not been

    assessed to till date.

    At the same time, Government of Nepal published the notification on the gazette dated

    Baishakh 2, 2065 (14th April 2008) stating the permit to collect wild orchids for the trade

    which were banned for the collection previously. Due to this notification, some rare and

  • 8/14/2019 Assessment of Orchids and Estimation of Current Stock of Traded Orchids in Rolpa District, Nepal

    6/38

    endangered orchid species are in threat of over exploitation from their natural habitats for

    trade.

    On the basis of these information and considering the enumeration and assessment of

    orchids in the district, District Forest Office (DFO), Rolpa and Livelihood Forestry Project

    (LFP), Rolpa wished to carry out a detail enumeration and an assessment of orchids in thedistrict. In the same time, District Forest Office Rolpa needed a measurement of stock for

    releasing permit issue. Therefore, a team of two botanists conducted a study on 17 VDCs of

    Rolpa district.

    Systematic investigation of orchids should be undertaken for the complete indexing of the

    orchids and contributing to a red data book regarding the threatened and endangered

    species. Orchid reserves in orchid hotspots should be established for the preservation and

    regeneration of orchids. The collection of wild species of orchids for commercialization

    should be banned and the rare and endangered species should be introduced in Botanic

    gardens. Systematic research on propagation technique such as tissue culture should bepromoted for the commercially valuable orchids.

    1.2 Objectives

    The present study aims to enumerate the orchid species of Rolpa district. The specific

    objectives are as follows:

    1. To identify the orchid hotspots in the selected VDCs of Rolpa district.

    2. To enumerate the orchid species distributed in the selected VDCs of Rolpa district.

    3. To assess the current stock of traded orchid species in the selected VDCs of Rolpa

    district.

    4. To assess the threat and formulate the conservation strategies of orchids in Rolpa

    district.

    1.3 Limitations of the study

    Most of epiphytic orchids flower during April-June. Field survey (September-October) was

    dry and most of terrestrial orchids had died or were not in flowering stage. Thus few orchids

    without flower were not identified.

    Due to limited time frame, 17 VDCs out of 51 was surveyed. Only two speices were in tradefrom Rolpa district Thus current stock was calculated for these two species only.

    CHAPTER TWO

    2.1 Physiognomy of Rolpa district

    Rolpa district lies in the mid western region in Rapti Zone, Nepal. By covering an area of

    187,150 ha, it lies at 280 8280 38 N latitude and 830 10840 9 E longitude. The altitudinal

    range varies from 7013639m representing tropical, temperate and sub-alpine types of

    climate. The district is surrounded by Rukum to the North, Baglung and Pyuthan to the East,Salyan to the West and Pyuthan and Dang to the South.

    Of the total land area, 94,097 ha (50.28%) area is covered with forest and grazing land

    coverage of 32,699 ha (17.47%) area of the district.

    The maximum temperature of the district is 31.20C and the minimum temperature as 3.60C.

    Similarly, the maximum rainfall was recorded as 1836mm and the minimum rainfall as

    1388mm.

    The ecological zones of the district encompasses Sal, Chir Pine, Alder, Himalayan Oak-

    Laurel, Mixed Rhododendron-Oak, Temperate Mountain Oak, Rhododendron, sub-alpine

    scrub and sub-alpine meadow forest and vegetation types.

    2.2 Study areaOn the basis of the information on the availability and distribution of orchids in the district,

    Jhenam, Dubring, Sakhi, Dubidanda, Masina, Nuwagaon, Gairigaon, Kotgaun, Liwang,

    Khumel, Mijhing, Jaimakasala, Siuri, Seram, Uwa, Aresh and Tewang village development

    committees (VDCs) were chosen as the study area for the observation and assessment of

    Orchid resources in Rolpa. The map of the study area is shown below.

    CHAPTER THREE

    3.1 Data collection

    Primary data were collected using different tools like observation, measurement, interviews,

    consultation with key informants and other relevant PRA tools. Forest guards, herbs traders,

    hotel owners, and farmers were the main key informants interviewed. Verbal open ended

    questions were asked for the interview and discussions. The secondary information was

    collected from related publications, research papers, District Forest Office and other

    documents as per necessity. The secondary data were collected for the verification of

    primary data and additional information as well.

    3.2 Identification of orchid hotspot

    Orchid sampling and observation were conducted in defined habitats. The identification of

    orchids hotspots was done systematically by observing abundance, habitat, forest types,

    moisture, altitude and aspects. GPS coordinates/data were taken to locate the hotspots of

    orchid in their specific habitats.

    Habitats of epiphytic orchids were identified on the basis of researchers knowledge and

    expertise.

    3.3 Identification of orchids

    Observed orchids were identified visually on the basis of researchers knowledge.

    Unidentified species were collected and identified consulting with the reference literatures asStainton and Polunin (1984); Stainton (1988); Rajbhandari and Bhattarai (2001); Milleville

    and Shrestha (2005). Enumerations of all available orchids were carried out according to

    Rajbhandari and Bhattarai (2001) and Press et al. (2000).

    3.4 Stock estimation of traded orchids

    3.4.1 Abundance

    Abundance of particular species is defined as the number of species A found in all plots to

    the total area of the plots per hectare. It was calculated using the following formula as givenby Zobel et al. (1987):

    9/38

    For orchids, following steps were carried out in the field to find out the abundance.

    3.4.2 Current stock

    Traded orchid species were collected from the study sites in patches. Number of individuals

    in each patch was counted. Fresh weight of bulb/pseudo-bulb was taken in the field with the

    help of balance (Picture 1). The species were sun dried for 15-20 days according to the

    nature of orchids and dry weight of each bulb/pseudo-bulb was taken using digital balance.

    Finally total stock of traded orchid species per hectare was calculated.

    Number of orchids in a plot is calculated with the help of following steps

    1. Average number of plant is counted in each patch

    2. Total number of patches of "Species A" is counted in each quadrat.

    4.2 Habitat of orchids

    The mid altitudes between 1,0002,300m of the studied VDCs harbor the highest number of

    epiphytic orchid species in Rolpa district. Whereas, few terrestrial orchid species grow on

    meadows and underlying forest covers ranging from sub-tropical to sub-alpine regions in

    studied VDCs. The suitability of luxuriant growth of epiphytic orchids in the mid-hills is due to

    the moisture rich mossy habitat as a result of high cloud formation.

    Typically, the mid altitudes benefit twice daily from a cloud bath by the rising and falling

    cloud line. As a result of such a daily weather cycle in the mid-hills, the medium bark of

    trees/shrubs decompose so quickly into anaerobic sludge combined with lots of air

    movement and strong light seems to make orchids as sturdy and resilient.

    4.2.1 Host plants of orchids

    Most of the orchid species were found growing in Angeri (Lyonia ovalifolia), Banjh (Quercus

    leucotrichophora), Katush (Castanopsis indica), Lali Gurans (Rhododendron arboreum) and

    Kaphal (Myrica esculenta) in sub-tropical and temperate regions. Similarly, Chiuri

    (Diploknema butyracea), Mauwa (Engelhardia spicata) and Sal (Shorea robusta) host

    majority of orchid species in tropical and sub-tropical regions of the studied VDCs of Rolpa

    district. The lists of host plants along with epiphytic orchids are presented in Table 2.

    4.7 Assessment of threat

    Orchids are well known for their horticultural values and the export of wild orchids from

    Nepal posed a continued threat to wild populations which have been reduced due to habitat

    destruction. Since 2008, Nepal government has permitted the export of wild orchids which

    were restricted before. Therefore, the over exploitation of wild orchids by local vendors for

    sale to the traders/exporters has exerted serious threat to most of the sub-tropical and some

    temperate epiphytic species. Furthermore, the favourable orchid habitats are heavily

    encroached for the settlement and cultivation.

    4.7.1 Legal and conservation gaps

    The issues relating to sustainable use of orchids are:

    Lack of inventory of orchid species and their abundance and distribution.

    Slow process to protect and manage critical wildlife habitats.

    Difficulty in identifying orchids not in flower.

    Lack of awareness by developers on orchid conservation.

    Habitat destruction.

    Unsustainable harvesting due to lack of collection policy.

    No export quota system.

    Inadequate monitoring and regulatory mechanisms.

  • 8/14/2019 Assessment of Orchids and Estimation of Current Stock of Traded Orchids in Rolpa District, Nepal

    32/38

    The cost of repatriation of illegal shipments.

    The need for domestic trade regulations.

    4.8 Conservation strategies

    Orchids fall under CITES II category which is defined as species not yet threatened but

    which could become endangered if trade is not controlled. Collection and trade of orchids

    does not fall under the jurisdiction of CITES or any existing legislation. However, it is

    envisaged that with the development and enactment of regulations under the Endangered

    Species (Protection, Conservation and Regulation of Trade) Act, illegal trade and

    uncontrolled harvesting of orchids will be addressed.

    4.8.1 Goals and strategic directions

    Goal 1: Conserve orchid species and their habitats

    a. In-situ conservation

    Strategic directions

    Conduct orchid survey biannually.

    Establish habitat/Species management areas (equivalent to IUCN Category IV)

    where the ecosystems are healthy and a number of species present are threatened

    by proposed habitat alteration such as development or mining.

    Rehabilitate degraded orchid habitats and promote the recovery of endangered

    orchid species through the development and implementation of

    management/Recovery plans.

    Develop legislation for the establishment of areas to facilitate conservation of orchids

    and other species especially in areas that are zoned for development such as road

    construction and buildings.

    b. Ex-situ conservation

    Strategic directions

    Develop and review regularly, guidelines for rescue centres.

    Establish at least two rescue centres to house plants illegally exported. Establish and maintain a gene bank of endangered orchid species.

    Encourage the artificial propagation of orchid species from seeds and tissue culture

    by commercial growers such as the granting of tax exemptions for imported materials

    used in the artificial propagation of wild orchids from seeds.

    Develop and institute cooperative agreements between private landowners and the

    Government for the purposes of plant conservation and land restoration.

  • 8/14/2019 Assessment of Orchids and Estimation of Current Stock of Traded Orchids in Rolpa District, Nepal

    33/38

    Re-establish decimated orchid populations by cultivating and propagating in

    nurseries for reintroduction.

    Maintain and expand the orchid collection at the demonstration gardens.

    Goal 2: Ensure sustainable use of orchids

    a. Regulatory framework

    Strategic directions

    Complete amendments of the Wild Life Protection Act to incorporate the protection of

    endangered and endemic orchid species and establish quota restrictions on

    commercial species.

    A periodic review of the orchids on the protected list should be conducted for

    nomenclature changes, addition or deletion of species.

    Legislate the Nursery Inspection Form under the domestic trade regulations of the

    Endangered Species Act.

    Develop a field collection policy to prevent the over-exploitation of wild orchids and

    incorporate into the domestic legislation.

    Develop a registration process for commercial exporters and nurseries.

    Establish and implement an allowable annual trade quota system for international

    trade to cover registered and non-registered exporters.

    Develop regulations governing artificial propagation of wild species of the Trade in

    Endangered Species Act.

    Develop exemption certificates in accordance with the Endangered Species Act for

    persons trading in personal effects.

    Goal 3: Promote and facilitate research and training

    Training and research

    Strategic directions

    Develop and institute training programs for the identification of orchid species for

    District Forest Office Staff, Customs Officers, Taxonomists, Protected Areas

    Rangers, Plant Quarantine Officers and other relevant persons involved in the

    issuing of permits and security at airports.

    Conduct and support research for artificial propagation of Nepals native orchid

    species.

    34/38

    Goal 4: Public education and awareness

    Strategic directions

    Develop and implement a public education awareness program on the conservation

    of orchids and on the relevant resolutions of CITES.

    Educate developers, visitors and commercial exporters on conservation issues,

    CITES resolutions, the definitions and guidelines for export, the native orchid export

    list and, export procedures and permit system.

    Encourage individuals to purchase orchids from commercial growers, rather than

    collecting from the wild.

    Provide information on the method of processing plants for export to the electronic

    and print media, Ministry of Forest and Soil Conservation, Floriculture societies and

    libraries.

    Continue to erect posters at airports, hotels and wildlife attractions in order to

    promote public awareness. Develop and disseminate an Orchid Expertise List (these persons should be able to

    accurately identify orchid species, have working experience in the areas of Orchid

    conservation and/or bioengineering).

    Formulate and publicize a procedures manual for exporting orchids.

    Continue to establish a photographic and herbarium collection of native orchid

    species.

    CHAPTER FIVE

    5.1 Conclusion

    Orchids are among the most beautiful ornamental plants and carry medicinal and

    horticultural importance as well. Rolpa district is rich in orchid species resources with 36

    species of both terrestrial and epiphytic orchids identified in the studied 17 VDCs of the

    district. Orchid habitat hotspots and host plants were identified within the community forests

    as well as government managed forests at the altitudes between 1000-2300m in humid and

    moisture rich mixed broadleaved forest of the surveyed VDCs.

    The assessment of the current stocks of traded orchid species revealed that the abundance

    of Dendrobium denudans was found highest in Liwang VDC (15360/ha) with the current

    stock of 23.424kg/ha followed by Seram VDC with the abundance of 13800/ha having

    current stock of 21.045kg/ha and Uwa VDC with abundance of 13150/ha and current stock

    of 20.053kg/ha.

    Similarly, the abundance of Dendrobium eriiflorum was found highest in Siuri VDC

    (35530/ha) with the current stock of 54.183kg/ha followed by Seram VDC with the

    abundance of 31450/ha having current stock of 47.961kg/ha and Jaimakasala VDC with

    abundance of 26640/ha and current stock of 40.626kg/ha.

    Of the total broadleaved forest area of the surveyed VDCs, it is assumed that only 40% of

    the total broadleaved forest area host orchids. Based on that assumption, total stocks of

    orchids were calculated. Total stock of D. denudanswas recorded highest in Uwa VDC with

    11018.08 kg followed by Seram VDC with the stock of 9982.57 kg and Liwang VDC with

    total stock of 6057.35 kg.

    Total stock of D. eriiflorumwas recorded highest in Seram, Siuri and Jaimakasala with the

    total stock of 22750.01 kg, 7039.67 kg and 4933.46 kg respectively. However, total stock of

    orchids comprises of all size / age classes and cannot be harvested in totality.

    However, due to the habitat loss, forest destruction, degradation and over exploitation of

    beautiful and medicinal orchids for trade has posed threats to the conservation of orchids in

    the district. Conservation has not been coherent with the need of orchids. Therefore, detailed

    assessment to understand the current stock and overall conservation status of orchids in the

    district needs to be conducted, which is still lacking.

    5.2 Recommendation

    Orchid conservation awareness should be organized in every alternate year, so that the

    upcoming young generation should be made aware and educated about the importance

    of their forest ecosystem.

    Urgent need of plantation of suitable orchid host tree species and protection of thenaturally growing saplings of these host species.

    Government should develop orchid hotspot areas as the eco-tourism promotion, so that

    the local stakeholders can earn some kind of revenue from the resources.

    Facilitate the local communities to propagate some viable species and market them

    appropriately in order to bridge their monetary gaps with the help of the aesthetic and

    other values of these beautiful orchids.

    Establish and maintain a gene bank of endangered species.

    Maintain and expand the orchid collection at the demonstration gardens.

    Develop a field collection policy to prevent the over-exploitation of wild orchids and

    Incorporate into the management plan of community forests as wells as governmentmanaged forests.

    Develop and institute training programs for the identification of orchid species for District

    Forest Office staff, and other relevant persons involved in the issuing of permits.

    Prepare posters or yearly calendar with the photographs and description of endangered

    species of orchid and distribute to community forests user groups and other

    conservation groups in order to promote public awareness.
