Nepal Biodiversity Wealth Expands
Only 0.1 percent of the global landmass, Nepal boasts disproportionate wealth in biodiversity. And the riches are expanding.
A Nepal Monitor Report
Nepal’s inventory of new species is expanding by the day. A new report, released on World Environment day on June 5, in Kathmandu, says 30 new bird species and 4 mammals, and more than 700 flowering species were found in Nepal between 1996 and 2006.
The report, entitled Nepal Biodiversity Resource Book, says the new bird species include the Moustached Warbler, Greater White-fronted Goose, Spot-winged Rosefinch, Pallas’s Bunting, Red-throated Loon, Black-and-yellow Grosbeak, and Rufous-tailed Wheatear; the new mammal species are the Binturong, Indian Mongoose, Himalayan Marmot, and the Tibetan gazelle.
Protected areas have also increased in Nepal by nearly 9,000 sq km. These include the Shivapuri National Park, the Kangchenjunga and Manaslu conservation areas, and 11 buffer zones. Three sites - Bishazarital, Jagdishpur reservoir, and Ghodaghodital – were designated Ramsar sites in 2003.
The report says protected areas cover nearly 20% of the country's land. The government has banned the collection use, sale, distribution, transportation and export of three species (namely, Pancha ounle, Okhar ko bokara bark, and Kutaki) since 2001, and the export of eight species of plants and rock as well as the transportation, export, and felling of seven tree species for commercial purpose.
The network of protected areas includes 9 national parks, 3 wildlife reserves, 3 conservation areas and a hunting reserve. Four sites – the Sagarmatha and Chitwan national parks and the Lumbini and the Kathmandu Valleys – have been included in UNESCO’s List of World Heritage Sites. Apart from conservation of species in the wild, efforts have been made towards ex-situ conservation and specimen preservation.
While Nepal has only 0.1% of the global landmass, it has a disproportionately rich diversity of flora and fauna. It has the 10th richest flowering plant diversity in Asia, and ranks 31st globally. Mammal species comprise almost 4% of the global total, and bird species almost 9%. There are 11 bio-climatic zones and 9 land-based ecoregions. Of these, three are classified under critical/endangered, vulnerable and stable/intact.
Nepal’s natural resources are important for its economy. These include agricultural land, wetlands, forests, and protected areas. Agricultural, which covers 20% of land area, is the major determinant of economic activities. Forests cover 29% of land area.
“The high demand for agricultural land, however, has led to considerable deforestation and loss of land cover. Forest cover in the Terai and hill areas decreased at an annual rate of 1.3% and 2.3% respectively between 1978/79 and 1990/91. Despite this, forest areas do contribute to the national economy. For example, the majority of protected areas comprise forested land and their contribution to the national economy is of major importance,” the report added.
A number of legal instruments govern management of protected areas. Of these, the National Parks and Wildlife Conservation Act of 1973 is the principal legal instrument. The Act prohibits the hunting of any animals or birds, building any house, hut, or other structure, clearing or cultivation or harvesting, cutting, burning, or damaging any tree, bush, or other forest product, and mining in national parks, or protected areas. Additionally, 26 mammal species, 9 bird species, and 3 reptile species are protected under the Act.
Despite this, several species are listed as threatened. Among these, the pigmy hog the slender-billed vulture, pink-headed duck, and the white-rumped vulture are listed as critically endangered. It is believed that the pigmy hog and the Indian Chevrotain have probably become extinct in Nepal. Of plant species, the Andrewsianthus ferrugineus and Diplocolea sikkimensis are considered endangered.
The Nepal Biodiversity Resource Book was produced jointly by the Government of Nepal, Ministry of Environment, Science and Technology, the International Centre for Integrated Mountain Development and the United Nations Environment Programme. The report focuses on the flora and fauna diversity in the Protected Areas, Ramsar Sites, and World Heritage Sites of Nepal as a means of having updated and comprehensive information on Nepal’s biodiversity profile.
The following is the summary of the 128-page report:Executive Summary: Nepal Biodiversity Resource Book
Biodiversity Profiles of Nepal 1996 (BPN) is a landmark endeavour to document all the information available and also recorded in the field on Nepal’s biodiversity. In 16 volumes of documents, the profiles recorded 181 mammal species, 844 bird species, 100 reptile species, 43 amphibian species, 185 freshwater fish species, and 635 butterfly species. In the context of flora, BPN recorded 5,160 species of flowering plants and 1,120 non-flowering plants. According to BPN, Nepal ranks 10th in terms of richest flowering plant diversity in Asia, and 31st in the world.
Since 1996 when the BPN documents were published, Nepal has advanced further in biodiversity conservation and protected areas management. A total of 8,778 sq km of protected areas has been added to the country’s protected areas between 1996 and 2004, including Shivapuri National Park, Kangchenjunga and Manaslu conservation areas, and 11 buffer zones.
In 1996, IUCN-Nepal prepared a detailed wetlands inventory of 163 sites from the Terai and 79 sites from the hills and mountains; three sites, Bishazari Tal, Jagdishpur reservoir, and Ghodaghodi Tal, have been designated as Ramsar sites in 2003.
Since 1996, at least seven species of birds have been newly recorded in Nepal, and the number of bird species recorded in the protected areas has increased significantly. In Shivapuri National Park, for example, the number of bird species recorded in 1996 was 151; in 2002 it was 177, and 311 in 2005.
The number of species of flowering plants on record to date is about 5,900 compared to 5,160 recorded by BPN in 1996. A new chapter on entomology has been opened following the publication of the inventory of insects of Nepal in 1997 and 1998.
The overall goal of the Nepal Biodiversity Yearbook Project (NBYP) was to establish a system for updating Nepal’s biodiversity resources every year into a Nepal Biodiversity Resource Book 2006, 2007, 2008, and so on, based on scientific studies.
The main objective of NBYP was to prepare a resource book 2006 on Nepal’s biodiversity by updating the 1996 Biodiversity Profiles of Nepal using published information between 1996 and 2005 and field verification.
The NBYP was implemented in five stages preparatory to publication. Upon completion of the preparatory stage, Nepal Nature dot Com formed a working team to implement the Project. Team formation approach followed the steps taken by BPP in 1996, with essential modifications.
The checklists of fauna and flora compiled for the resource book have been derived primarily from the BPP documents. To update the checklists, references were made to publications made by various conservation organizations.
The first draft of the resource book was reviewed by six experts. A consultative meeting of 26 other experts representing 13 organisations was also held in Kathmandu on November 28, 2006 to discuss the draft. Conservation organisations were provided access to the digital version of the draft to facilitate review and feedback.
The major outputs of NBYP were the two resource book documents, one in English, one in Nepali, and a digital version of both. NBYP 2006 focuses on flora and fauna diversity in protected areas, Ramsar sites, and World Heritage Sites of Nepal.
Nepal, with area 147,181 sq km, occupies the central part of the Himalayas standing between the Palaeartic (Holartic) and Plaeotropical (Indo-Malayan) regions. The country is located between latitudes 26º22’ and 30º27’ N and longitudes 80º40’ and 88º12’ E. Altitude varies from 67m above sea level at Kechana Kalan, Jhapa in the south-eastern Terai to 8848m at Mt. Sagarmatha, the highest point in the world. Nepal’s biodiversity is a reflection of its unique geographic position and variations in altitude and climate.
The extreme altitudinal gradient has resulted in 11 bio-climatic zones ranging from tropical to Nival within a short horizontal span. The Terai belt (67-300m) is a flat stretch of fertile agricultural land in southern Nepal, which forms part of the alluvial Gangetic plain. The Siwalik Hills Zone (700-1500m) rises abruptly from the Terai plains and is mainly composed of sedimentary rock and big boulders. The Mahabharat Lek (1500m to 2700m) lies between the Siwalik Hills to the south and the midlands to the
north. The Midlands (average altitude 2000m) occupy the central region of the country. The Himalayan zone (above 4000m) lies in the north and stretches from east to west of the country. It consists of subalpine and alpine climates where summer grazing pastures are found in the lower elevations and high altitude plant species adapted to extremes of cold and desiccation grow in higher elevations. There are several inner Himalayan valleys with desert conditions such as the upper Kaligandaki and Bheri valleys located at altitudes above 3600m.
A wide range of climatic conditions exists in Nepal, mainly as a result of variations in altitude. This is reflected in contrasting habitats, vegetation, and fauna. Other important climatic factors influencing biodiversity and the composition of flora and fauna in Nepal include rainfall, winter snowfall, temperature, and aspect.
Soil formation is related to the physiographic zone. In the Terai, the soil is alluvial and fine to mediumtextured.
In the Siwalik Hills, it is made up of sedimentary rocks with a sandy texture, while in the Mid-Hills soil is medium to light in texture with a predominance of coarse-grained sand and gravel. The soil in the high mountains is shallow, stony, and glacial.
The country’s major perennial river systems are the Mahakali, Karnali, Narayani, and Koshi rivers, all of which originate in the Himalayas. These rivers contain water resources that hold tremendous potential for large-scale hydropower and irrigation development. Medium-sized rivers include the Babai, West Rapti, Bagmati, Kamla, Kankai, and Mechi rivers that generally originate in the Mid-hills or in the Mahabharat range. The Terai region contains many small and usually seasonal rivers most of which originate in the Siwalik Hills.
The latest physiographic data show that Nepal comprises around 4.27 million hectares (29% of total land area) of forest, 1.56 million hectares (10.6%) of scrubland and degraded forest, 1.7 million hectares (12%) of grassland, 3.0 million hectares (21%) of farmland, and about 1.0 million hectares (7%) of uncultivated lands. Forest cover in the Terai and Hill areas is reported to have decreased at an annual rate of 1.3% and 2.3%, respectively between 1978/79 and 1990/91.
Nepal has a population of 23.2 million (2001 census). Some 48.5% of the population lives in the Terai, 44.2% in the Hills, and 7.3% in the Mountains. Average population density is 157.73/km2, with the highest density (330.78/km2) in the Terai, medium density in the Hills (167.44/km2), and lowest in the Mountains (32.62/km2). In relation to Nepal’s five development regions, the Central Development Region accommodates 34.7% of the total population, followed by the Eastern Development Region, 23.1%; the Western Development Region, 19.6%; the Mid-Western Development Region, 12.9%; and the Far-Western Development Region, 9.5%.
Nepal ranks 138th out of 177 countries in the 2006 Human Development Index, with 62.1 years life expectancy at birth, 48.6% adult literacy rate, and 147th ranking in purchasing power parity of US$1,490. The country ranks 68th among 102 developing countries in Human Poverty Index.
The economic well being of Nepal is closely bound to its natural resources – agricultural land, wetlands, forests, and protected areas. Although only 20% of land area is agricultural, agriculture is the major determinant of economic activities and the nation’s socio-political identity. Forests cover some 29% of the land area. The high demand for agricultural land has led to considerable deforestation and loss of land cover. Natural phenomena such as floods and landslides contribute to an annual soil loss of 20-25 tonnes/ha. The majority of protected areas including the major national parks comprise forested land.
Their contribution to the national economy through foreign exchange earnings is of major importance. Nepal’s bioresources in the international trade are mostly wild in origin. The 188 biomaterials commonly found in international trade consists of various plant parts such as roots and tubers (39 plants), barks (seven plants), leaves (26 plants), flowers (14 plants), fruits and seeds (61 plants), whole plants (12 plants), gums and resins (eight plants), and miscellaneous other plants (11).
Tourism is the second most important source of foreign exchange for Nepal. During the period 1996-2005, over 45% of total visitors to Nepal, on average, visited the protected areas. Tourist arrivals in Nepal, as well as in its protected areas, are expected to grow by 8-10% annually.
The National Parks and Wildlife Conservation Act (NPWCA) 1973 and its seven associated regulations are the principal legal instruments that govern the management of Nepal’s protected areas. Section 3 of the NPWCA prohibits hunting of animals or birds, building any house, hut, or structure, clearing or cultivation on any part of the land, or harvesting any crops, cutting, burning, or damaging any tree, bush, or other forest product, and mining within national parks or protected areas. The Act provides complete protection to 27 species of mammals, nine species of birds, and three species of reptiles. Since its promulgation in 1973, five amendments have been made to this Act. Four amendments were made effective 1993. The Fifth Amendment in 2005 accommodated the provision handing over management responsibility for the protected areas to organisations established under the Act. Three regulations formulated after 1996 mainly reflect upon government policy involving local communities in the management of protected areas.
Acts and regulations pertinent to forests, watersheds, the environment, livestock, self- governance, and tourism are equally significant for the conservation of flora and fauna. The government recently formulated four main policies pertaining to biodiversity conservation. They are, the Working Procedure for the Implementation of the Policy with Regard to the Handover of the Management of National Parks, Wildlife Reserves and Conservation Areas to Non-governmental Organisations or Other Organisations; the Domesticated Elephant Management Policy 2003; the Working Policy on Wildlife Farming, Breeding and Research 2003; and the National Wetland Policy of Nepal 2003.
As a signatory to the Convention on Biological Diversity at the Earth Summit (1992), Nepal has fulfilled its commitment and has developed a Nepal Biodiversity Strategy in 2002 to meet the obligations of the Convention and to serve as an overall framework for the conservation and sustainable use of its rich biodiversity and biological resources. Nepal is a party to eight major international agreements and conventions on biodiversity conservation (Table 4). Methods for transforming international treaty norms into internal law are in progress in Nepal.
Apart from international conventions and treaties, global affiliations pertinent to biodiversity conservation and sustainable development that Nepal has been affiliated with include the World Trade Organization (WTO), the World Conservation Union - IUCN, and the Global Tiger Forum. Nepal has also followed the spirit of the World Conservation Strategy 1980 and the World Charter for Nature 1982.
Using the authority empowered by the 1973 NPWC Act, and in response to international conventions and treaties, the Government of Nepal has established a network of 16 protected areas (nine national parks, three wildlife reserves, three conservation areas, and one hunting reserve). Buffer zones have been established in eight of the nine national parks (except for Shivapuri National Park), and three wildlife reserves.
Four properties have been inscribed in the UNESCO List of World Heritage Sites. They include two natural properties namely Sagarmatha and Chitwan national parks, and two cultural properties namely Lumbini and the Kathmandu Valley. Of the seven monument zones of the Kathmandu Valley, three properties of national significance are Swayambhu, Pashupati, and Changunarayan.
There are four Ramsar sites of which Koshitappu is a wildlife reserve, and Beeshazar and Associated Lakes fall within the buffer zone of Chitwan National Park. The Jagdishpur reservoir is an artificial water body, whereas Ghodaghodi Tal is a natural lake.
The network of protected areas cover almost 20% of the country’s land compared to the global figure of 11% of the earth’s land surface under the protected area system. The protected areas of the world face a growing set of global challenges that threaten the existing capacity to protect and maintain the valuable diversity of life and the sources of ecosystem services for people.
Nepal has a complex biogeography due to its past geological history and its presence at the crossroads of two bio-geographic realms, Palaearctic and the Palaeotropic (Udvardy 1975), and two major zoogeographical Kingdoms: Palaearctic in the north and Indo-Malayan in the south.
Furthermore, Nepal lies at the crossroad of six floristic regions namely Central Asiatic in the north, Sino-Japanese in the east, South East Asia-Malaysia in the south east, Indian in the south, Sudano-Zambian south west, and Irano-Turanian in the west.
Adam Stainton (1972) used six climatic and vegetation divisions in his classification of forest types of Nepal, and recognised 35 forest types classified into ten major groups which have been widely adopted in later work. Jean-François Dobremez (1972, 1976) recognised four domains (western; northwestern; central; and eastern); six levels and 11 sublevels of bioclimatic zones, and 75 vegetation types.
According to the ecoregional classifications made by the Conservation Science Program of WWF US, Nepal’s landmass includes nine land-based ecoregions defined by ecological features, climate, and plant and animal communities. Of them, three each are in three different conservation statuses such as Critical/Endangered, Vulnerable, and Stable/Intact.
The vegetation types described by Dobremez and his Nepalese colleagues totaled 198 categories. The Biodiversity Profiles Project 1995 attempted to synthesise them into 118 categories. During 1998-99, IUCN revised the vegetation types and devised 59 vegetation types for the use of the Tree Improvement and Silvicultural Component/Natural Resource Management Sector Assistance Programme (TISC/NARMSAP). The 59 types have been further reduced to 36 in order to give a simplified ecological picture of Nepal’s vegetation based upon climax or near-climax vegetation type spread over potential areas of ecological homogeneity.
The monsoon climate and huge altitudinal range found in Nepal create a wide array of habitats, from the lowland (as low as 67m above mean sea level) evergreen tropical forests in the Terai and low hills (below 1000m) through temperate broadleaved and coniferous forests to the tree line. Above this, Rhododendron scrubland extends up to the high alpine meadows before plant life gives way to the frozen and biologically barren snow capped peaks including Mount Sagarmatha (8848m). The highest recorded flowering plants like Ermania himalayensis of the Brassicaceae family are found at around 6000m. The deep river valleys and gorges create their own microclimates.
Dramatic vegetation changes can be seen in relatively small areas with differing aspects and altitudes. Nepal comprises only 0.1% of land area on a global scale, but it possesses a disproportionately rich diversity of flora and fauna at genetic, species and ecosystem levels. These species are found in the dense tropical monsoon forests of the Terai, in the deciduous and coniferous forests of the subtropical and temperate regions, and in the sub-alpine and alpine pastures and snow-covered Himalayan peaks.
Nepal falls within two biogeographical realms - the Indo- Malayan and the Palaearctic realms – which add to the high biodiversity level. There has been comparatively much work carried out on the higher groups of plants (angiosperms and gymnosperms), but research on the lower groups has not been extensive or systematic.
Lichenologists estimate about 2,000 lichen species in Nepal of which 48 species are reported to be endemic to Nepal. There are 1,822 species of fungi, 687 species of algae, 853 species of bryophytes, and 534 species of ferns and fern allies in Nepal. Similarly, there are 6,391 angiosperm flora of which 25 species of gymnosperms have been listed in Nepal.
Nepal has a relatively high number of fauna species. Higher fauna groups have been relatively well studied; however, the taxonomy and distribution of lower fauna groups except for butterflies, and to some extent spiders, have yet to be studied. A comprehensive Fauna of Nepal guide is essential to understand the status of species for their conservation.
A checklist of 168 species of helminth parasites, 33 species of trematodes, 67 species of nematodes, 36 species of cestodes, and 32 species of plant nematodes has been recorded. There are 144 species of spiders, and approximately 5,052 species of insects.
So far, 2,253 species of moths (excluding Microlepidoptera) have been recorded in Nepal. The current list includes 651 species of butterflies and 785 species of moths.
There are 187 species of fish and 195 species of herpeto fauna (117 amphibians and 78 reptiles) in Nepal. The number of bird species is 874, and mammals, 185.
Of the total 874 species of birds, 62% are resident birds, 14% winter visitors, 12% passage migrants, 6% summer visitors, 5% residents and migrants, and 1% summer and winter visitors. The four new additions in the mammal checklist are the Binturong (Arctictis binturong), Indian Mongoose (Herpestes nyula), Himalayan marmot (Marmota himalayana) and Tibetan gazelle (Procapra picticaudata).
Mammals are well represented in the protected areas of Nepal. Species distributions are viewed from two perspectives: confinement, and richness. Of the total number of mammal species, the Terai-Siwaliks region harbours the highest number of confined species (35 mammal species, 111 bird species, 46 Herpeto species, and 106 fish species). The central phytogeographical region harbours the highest number of confined species (28 mammal species, 24 bird species, 40 Herpeto species, and 31 fish species). Both the regions combined, the central Terai-Siwaliks region, holds the highest number of species.
Based on phytogeographical and altitudinal zoning, Nepal’s landmass can be divided into nine blocks. The Mid Hills Centre block harbors the highest number of mammals (55%) and birds species (77%), whereas Terai-Siwaliks Centre harbours the highest number of herpeto (45%) and Fish species (74%).
Overall, the Mid Hills Centre has the highest species richness followed by the Terai Siwaliks Centre. There are 399 endemic flowering plants in Nepal of which about 63% are from the High Mountains, 38% from the Mid Hills, and only 5% from the Terai and Siwaliks. Similarly, the central region contains 66% of the total endemic species followed by western (32%) and eastern regions (29%).
The Himalayan field mouse (Apodemus gurkha) which is found in central Nepal between 2200-3600m, is the endemic mammal species of Nepal. The Spiny Babbler (Turdoides nipalensis) and the Nepal Kalij (Lophura leucomelanos leucomelanos) are endemic to Nepal. There are 14 species of herpetofauna and six species of fish that are endemic to Nepal. Similarly, one hundred and eight species of spiders are reported to be endemic to Nepal.
The updated version of the National Red Data Book of Nepal includes 59 mammal species, 279 bird species, 35 Herpeto species and 34 fish species. Of these, two species namely the Cheetah (Acinonyx jubatus) and Black musk deer (Moschus fuscus) have not probably been recorded in Nepal, and the pigmy hog (Sus salvanius) and the Indian Chevrotain (Moschiola meminna), have probably become extinct in Nepal.
Of the 11 bird species that were listed as Extinct in Nepal in the BPN, the presence of three species has been recently reported. Thirty-four species of plants have been included in the IUCN Red List. Of them, two species (Andrewsianthus ferrugineus and Diplocolea sikkimensis) are considered Endangered, five Vulnerable (Cycas pectinata, Dalbergia latifolia, Scaphophyllum speciosum, Takakia ceratophylla and Ulmus wallichiana), two Near Threatened (Aglaia cucullata and Cupressus torulosa), 24 of Least Concern, and one Data deficient (Taxus wallichiana).
Altogether, 173 mammal species are listed as Threatened by IUCN: one as Critically Endangered (pigmy hog, Sus salvanius), eleven as Endangered, 21 as Vulnerable, 19 as Near Threatened, 120 of Least Concern, and one Data deficient (Csorba’s Mouse-Eared Bat Myotis csorbai).
Of the total number of bird species (874), three species are critically endangered (Slender-Billed Vulture Gyps tenuirostris, Pink-Headed Duck Rhodonessa caryophyllacea, and White-Rumped Vulture Gyps bengalensis), six Endangered, 23 Vulnerable, 25 Near Threatened and 813 are of Least Concern.
Under the Forest Act 1993, the Government of Nepal has banned the collection use, sale, distribution, transportation, and export of three species effective from February 12, 2001. They are the Pancha ounle (Dactylorhiza hatagirea), Okhar ko bokara (Juglans regia bark) and ‘Kutki’ (Neopicrorhiza scrophulariflora). The government has also banned the export of eight species of plants and rock exudes (shilajit), except for their processed product, and upon the permission of the Department of Forests.
Likewise, the government has banned transportation, export, and felling of seven tree species for commercial purposes. In addition, 26 mammal species, nine bird species, and three reptile species have been listed as protected under the 1973 NPWC Act. However, 10 species of fish and 12 species of butterflies are in need of protection.
In 2003, the Government of Nepal approved the Working Policy on Wild Animal Farming, Breeding and Research. Under its provision, seven species of mammals, one species of amphibian (Gharial crocodile Gavialis gangeticus), all snakes (77 species in total), and all species birds (874 species) including three protected ones.
Nepal is a signatory of the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) since 1975; a number of Nepali species are listed under various CITES Appendices, such as 139 species of plants, 66 species of mammals, 128 species of birds and 26species of fish.
Of the total 181 mammal species excluding four extinct species, 28 species are found only outside the protected sites. Fifteen of these species are bats, 10 species are rats, shrew, and Pikas, and three others are Large-toothed ferret badgers (Melogale personata), Malayan porcupines (Hystrix brachyura), and Tibetan antelopes (Pantholops hodgsoni).
Of the total 867 bird species found in Nepal excluding seven extinct species, only 37 species (5%) are found outside protected sites. Of them, 14 species are migrants, four species are summer/winter visitors, and 19 species are resident birds.
One-third of the total number of Herpeto species (65) and only 25 species of fish are found outside protected sites.
Khaptad National Park (225 km2) and buffer zone (216 km2)

(Also see Sagarmatha National Park and Buffer Zone)
Based on a comprehensive assessment of the status and issues of biodiversity in Nepal, future work must address the following issues and tasks.
1. Biodiversity explorations of ecological ‘blank spots’, such as the High Mountain regions and the Western region, with focus on lower plants (algae, fungi, etc) and invertebrates (insects, among others)
2. Protection of five vegetation types not represented under the current 16 protected areas by adopting appropriate strategies such as community forestry, and botanical gardens
3. Development and regular updating of flora checklists, including that of lower plants, as 4,134 species and subspecies of flowering plants including 269 endemic species, grow outside the 23 protected sites (16 protected areas, four Ramsar sites, and four World Heritage sites and monuments)
4. Development and regular updating of checklists of fauna, including invertebrates of the protected sites on a regular basis
5. Focused research on particular species such as such as the Cheetah (Acinonyx jubatus), Black musk deer (Moschus fuscus), Pigmy hog (Sus salvanius), and the Indian chevrotain (Moschiola meminna) remains subject to debate in terms of their existence and distribution in the country but is vital
6. The 28 species of fauna found only outside the 23 protected sites (16 PAs, four RSs and four WHS/monuments) merit further scrutiny
7. Protection of bat habitats, caves, and trees, is vital as 15 of the 37 species of bats live outside protected sites
8. Lateral linkages of NBRB information with existing national and global biodiversity databases covering flora, fauna, and protected sites of Nepal, as well as with websites maintained by conservation organisations pertinent to Nepal
9. Studies of the population dynamics and habitats of mammals, birds, herpeto, and fish need to be carried out in relation to the IUCN Red List
10. Review and update of the National Red Data Book of Nepal from the following perspectives:
a. Four extinct and four new additions of mammal species
b. Reappearance of four species of birds previously believed to be extinct
c. Updated checklist of herpeto and fish
11. Implementation of the 2003 Working Policy on Wild Animal Farming, Breeding and Research.
12. Continuous review of current activities and priorities of the botanical gardens and herbaria, as well as the zoos and natural history and wildlife museums
13. Review of existing government policies on banning commercial exploitation of plant species, and the working policy on wild animal farming from the perspectives of the updated NRDB, IUCN Red List, CITES Appendices, and the list of economically important species
Based on the biodiversity assessment the following conclusions have been made:
Of the 36 types of vegetation as simplified from the previous classifications, 31 types are represented in the 16 protected areas. Annapurna Conservation Area represents 16 vegetation types. The five types of vegetation that are not represented in the 16 protected areas are forests of Fir (Abies lasiocarpa), Hemlock (Tsuga spp. Viburnum, Viburnum spp) –Oak (Quercus laurifolia), Lithocarpus, Rhododendron, Olea (Olives), and Eugenia (myrtle family Myrtaceae) and Ostodes (family Euphorbiaceae).
By 2006, total number of flowering plant species recorded from Nepal is 6,391 representing 1,590 genera and 231 families compared to 4,259 species representing 1,447 genera and 194 families in 1995. Nepal’s share of flowering plants species is 2.76% of global totals compared to earlier records of 2.36%. Nepal’s share of pteriodophytes is 5.15% compared to earlier records of 4.45%.
The present number of flowering plant species endemic to Nepal is 399 compared to earlier records of 246, which has been reduced by 40 due to possible extinction (eight species) and new reporting elsewhere (32). The number of species included in the IUCN Red List is 34, which is approximately 0.5% of the total number of species in the IUCN Red List. There are 72 plant species regarded as having high commercial value. The Government of Nepal has banned commercial exploitation of 18 species of
plants, and the CITES appendices include 139 species.
There are 2,532 species of vascular plants represented by 1,034 genera and 199 families in the protected sites. Some 130 endemic species are found in the protected sites. On average, the NBY records of flowering plant species are 40% more compared to the BPN estimates for protected areas.
The current checklist includes 185 species of mammals of which four species are believed to be extinct from Nepal, and four new additions. In general, the total number of reported fauna species has increased since 1996. The number of bird species is 874 compared to 843 in 1995, and herpeto species 195 compared to 143 in 1995.
A new field of entomology has been opened with the publication of the IUCN Red List, among others, which has recorded 536 species under 17 orders from Protura to Odonata, 789 species of moths, and 656 species of butterflies. Remarkably, of the known 5,052 species of insects recorded from Nepal, 1,131 species, which is over 22% of the world list, are species that have been first discovered and described from Nepalese specimens.
Nepal’s share of the mammal species is 3.96% of global totals, and bird species 8.9%. The Terai-Siwaliks region harbors the highest number of confined species (35 mammal species, 111 bird species, 46 herpeto species, and 106 fish species) compared to other physiographical regions.
Similarly, the central phytogeographical region harbors the highest number of confined species (28 mammal species, 24 bird species, 40 herpeto species, and 31 fish species) compared to the eastern and western regions. For both combined regions combined, the central Terai-Siwaliks region has the highest recorded number of confined species.
There are 11 mammal species found in all nine regions, but there are 11 other mammal species that are not reported in any of these regions. In case of the birds, 104 species are found in all nine regions, but 41 species are not reported in any of the regions.
Among the nine regions, the Mid Hills Center harbors the highest number of mammals (55%) and birds species (77%), whereas Terai-Siwaliks Center harbors the highest number of herpeto species (45%).
The eastern Terai-Siwaliks houses 74% of all fish species found in Nepal. Overall, the Mid Hills Centre has the highest species richness, followed by the Terai Siwalik Center, the Terai Siwalik East, the Terai Siwalik West, the Mid Hills East, the Highlands Center, Mid Hills West, Highlands East, and Highlands West.
Annapurna Conservation Area (ACA) harbors 97 mammal species (52%), and Chitwan National Park (CNP) harbors 539 species (62%). The CNP and ACA combined are home to 29% herpeto species, and 66% fish species found in Nepal.
The only endemic mammal in Nepal, the Himalayan field mouse (Apodemus gurkha), is found in the Central Mid Hills and High Mountain regions. In the case of birds, the endemic Spiny Babbler (Turdoides nipalensis), is found in the Terai-Siwaliks and Mid Hills regions. The subspecies, Nepal Kalij (Lophura leucomelanos leucomelanos) is also endemic to Nepal and is found in the western regions. Fourteen species of herpetofauna and six species fish are endemic to Nepal.
The NRDB includes 59 mammal species, 279 bird species, 35 Herpeto species, and 34 fish species, of which four species of mammals and seven species birds are believed to be extinct, according to the updated checklists. Altogether, 173 mammal species (nearly 94% of total 185 mammal species) are listed as threatened by IUCN. Of the total number of bird species (874), three species are critically endangered (the Slender-billed vulture Gyps tenuirostris, the Pink-headed duck Rhodonessa caryophyllacea and the White-rumped vulture Gyps bengalensis). Sixty-four species of herpeto (34% of total herpeto species) are listed in the IUCN Red List.
Twenty-seven mammal species, nine bird species, and three reptile species are listed as protected species under the NPWC Act 1973. Ten species of fish and 12 species of butterflies are in need of protection. Sixty-six species of mammals are listed in the CITES Appendices.
In case of fauna, the number of birds reported from the protected areas has increased considerably since 1996. For example, the number of birds listed for Chitwan National Park was 483 in 1996 compared to 539 in 2006, and for Koshitappu 199 in 2006 compared to 485 in 1996. However, the number of mammal species has decreased by one in Sagarmatha National Park, due to non-reporting of the Black musk deer.
Of the total 181 mammal species excluding four extinct species, 28 species are found outside protected sites. Of them, 15 species are bats (out of a total 37 species), 10 species are the shrew, rats, and Pikas, and three other species. Three species namely, the Golden jackal (Canis aureus), Rhesus macaque (Macaca mulatta) and Common leopard (Panthera pardus) are found in the 20 protected sites.
Of the total 867 bird species excluding seven extinct species found in Nepal, 37 species (5%) are found outside protected sites. One-third of the total number (65) of Herpeto species are found outside protected sites, and 25 species of fish are also outside protected sites. In case of herpetofauna, the number of reported species has increased in all protected areas. Similarly, the number of fish species in Chitwan National Park was recorded to be 125 in 1996, and only 124 in 2006.
Separate lists of fauna species have been prepared for globally significant areas such as Ramsar sites and World Heritage Sites. Compared to protected areas, these areas have been studied less and limited data are available.
According to the mammal checklists (185), based on the available records by 2006, the Annapurna Conservation Area records the highest number of species (97), followed by Makalu-Barun National Park (81), compared to 13 in the Kanchenjunga Conservation Area. Similarly, the number of mammal species in Ghodaghodi Tal Ramsar site is 34 compared to six in Jagdishpur Reservoir Ramsar site, nine in Pashupati, and six in Swayambhu.
According to the bird checklists (874) based on available records by 2006, the Chitwan National Park records the highest number of species (539) followed by Parsa Wildlife Reserve (503), and 137 in Dhorpatan Hunting Reserve. Similarly, the number of species in Bishazari Tal Ramsar site is 271 compared to 45 in Jagdishpur Reservoir Ramsar site, and 64 bird species in Swayambhu compared to 51 in Changunarayan.
These variations in recorded number of faunal species in protected sites are primarily due to differing intensities of biological explorations in these sites.
Apart from conservation of species in the wild, some efforts have been made towards ex-situ conservation and specimen preservation. There is a network of 11 botanical gardens across the country. The central botanical garden of Godavari houses nearly 300 species of plants.
The National Herbarium (KATH) houses over 161,800 specimens, and the Central Department of Botany of the Tribhuvan University (TUCH) houses 20,000 specimens.
The Central Zoo houses 119 species of 970 animals of which there are 33 species of 206 mammals, 60 species of 321 birds, 17 species of 424 fish species, and nine species of 19 reptiles. The Hetauda Municipality Zoo houses species of the Spotted deer, Barking deer, hares, birds, and tortoises, amongst others.
Captive breeding of crocodiles has been carried out successfully in the Gharial farm in Chitwan. Between 1978 and 2005, 661 captive bred Gharials were released into the rivers of Nepal. There are 171 domesticated elephants in Nepal, of which 77 belong to the government, nine to Nepal Trust for Nature Conservation, and 85 to the private sector.
Since 1986, translocation of rhinos has been carried out successfully using Chitwan National Park as a gene pool. Between 1986 and 2003, a total of 87 rhinos (39 males, and 48 females) have been translocated to Bardia National Park (83), and Shuklaphanta Wildlife Reserve (4). Blackbuck translocation was initiated in 1992 from the Central Zoo to Bardia National Park, and recently to Pashupati World Heritage Site.
The Natural History Museum houses over 40,000 zoological specimens amd over 9,000 botanical specimens. The wildlife museums in the protected areas have preserved a number of specimens of wildlife and plants mostly found locally.
