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

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):

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.

harvested in totality.
4.6 Uses of orchids
Orchids are mostly used for ornamental purpose and some are used for medicinal purpose.
Large numbers of native orchids of Nepal are beautiful and carry horticultural importance.The most beautiful orchid species of Nepal belong to the following genera: Aerides,
Ascocentrum, Arundina, Bulbophyllum, Calanthe, Coelogyne, Cymbidium, Dendrobium,
Epigeneium, Eria, Esmeralda, Phaius, Phalaenopsis, Pleione, Rhynchostylis, Thunia,
Trudelia, Vandaand Vandopsis.
Species cultivated for ornamental purpose, include Aerides multiflora, Ascocentrum
ampullaceum, Bulbophyllum leopardinum, Calanthemasuca, C. plantaginea, C. tricarinata,
Coelogyne cristata, Cymbidium elegans, C. iridioides, Dendrobium densiflorum, D.
moschatum, D. nobile, Pleionepraecox, Rhynchostylisretusaand Vanda tessellata. Some
important medicinal orchids of Nepal are mentioned by Rajbhandari et al. (2000). They areBrachycorythis obcordata, Coelogyne flavida, Coelogyne stricta, Cymbidium aloifolium,
Dactylorhiza hatagirea, Eulophia nuda, Flickingeria macraei, Pholidota imbricata, Luisia
zeylanica and Vanda tessellata. Highly exploited orchids for medicinal purpose are
Flickingeria macraei found in tropical and sub-tropical regions and Dactylorhiza hatagirea
found in the sub-alpine and alpine regions (Bailes, 1985).
4.6.1 Medicinal uses of orchids
Some species of orchids are used for the treatment of various ailments by the communities
living in the remote parts as a primary health care. The traditional use practices of orchidsare given in Table 4.

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