Nepal is a small country, covering only 0.09% of the Earth’s land surface, but it is very important to global conservation as it is at the heart of the Himalayan Region - one of the world’s top 20 hottest global biodiversity hotspots, and the many and varied habitats support a great diversity of living organisms. It is estimated that 7000 higher plant species occur in Nepal, with some 300 of these only found in (endemic to) Nepal. Nine species of flowering plants are now suspected to be extinct in Nepal, eight of these were endemic species (Shrestha & Joshi, 1996).
Almost all of the 27 million people in Nepal depend on plant resources for their very livelihood, and ever increasing pressures from a burgeoning population and industrialisation take their toll on the environment. Nepalese culture has always respected the preservation of plants and forests, and there is a long history of conservation awareness: many sacred forests have been preserved for centuries according to deep-rooted religious traditions. A great deal of effort has been made over recent years to protect and manage biological resources and biodiversity. Government of Nepal began implementing its National Conservation Strategy in 1988, and in 2002 reiterated the importance of conservation through the publication of the Nepal Biodiversity Strategy (NBS 2002). This strategy states that “Biological diversity in Nepal is closely linked to the livelihoods and economic development of most of her people, and relates to agricultural productivity and sustainability, human health and nutrition, indigenous knowledge, gender equality, building materials, water resources and the aesthetic and cultural well being of our society."
Much of the loss of habitats occurred over a thirty-year period (1950-1980) when there were little controls on development. However, Government of Nepal is now fully committed to conservation and legislation is in place to help combat problems and Nepal is actively addressing its obligations as a signatory to the CBD. Implementing conservation measures is not easy in rural areas where the land and surrounding forest are used for subsistence, and it is recognised that long term solutions must also include elements of poverty alleviation and sustainable development. However, there have already been some successes, as a good network of protected areas has been established, and there is evidence that the extent and quality of forest cover has increased since 1980. The NBS concludes that “despite the conservation benefit provided by the PAs [protected areas] network, biodiversity loss in Nepal continues unabated." The most critical threats to conservation is deforestation, habitat destruction and unsustainable harvesting of wild populations.
- Widespread poverty and intimate dependence on almost all of the population on natural resources for their livelihood.
- Forests exploited as a major source of revenue until the late 1980’s.
- Fast population growth (2.23% in 2004)increasing demands for fuel, timber, fodder, grazing and agricultural land, leading to encroachment into natural ecosystems.
- Mass migration of people into the Terai and Dun valleys following malaria eradication in the mid 1950’s (see below under Terai), and refugee relocation from neighbouring countries.
- Increasing urbanisaton with migration rates from the countryside to urban areas in Nepal estimated at about 8% (the highest in South Asia), and the quality of life in the rapidly expanding major towns and cities is now suffering due to the added strain on sewerage, electricity and drinking water supplies, housing and vehicle pollution.
- Landslides in hilly regions (75% of landslides in Nepal occur naturally), especially during the monsoon (June-September) when the topsoil becomes saturated with water. All of Nepal's rivers flow across the Ganetic plain and drain into the Ganges, and so the floods that frequently devastate Nepal also bring disaster to India.
- Topsoil erosion, caused by natural and anthropogenic activities, leading to desertification and loss of soil fertility. The rat of soil loss for intact forested areas is estimated at below 1t/ha/yr, in degraded forest this increases to over 4t/ha/yr, and up to 200t/ha/yr in critically damaged areas.
Anthropogenic causes: - Pollution and environmental degradation, especially in urban and industrial areas.
- Water supply has been affected by glacial retreat and contamination is a problem through human and animal waste, agricultural runoff and industrial effluents.
- Tourism and mountaineering expeditions in alpine areas (especially fuel wood needs of porters and support staff).
- Deforestation (past clearances for agriculture, and now mainly cutting for fuel wood) has led to severe environmental degradation and soil erosion.
- Fire, either deliberate or accidental, has profound effects on ecosystems, destroying forests and preventing re-growth. Fire may promote luxuriant growth of grasses in old pasture, but the timescale for forest regeneration is long.
- Overgrazing (especially by yaks and sheep) leading to an increase in unpalatable species, inhibition of ecological succession and promotion soil erosion.
- Alien species spread by increased human movement, out-compete native plants.
- Illegal trade and collection from wild sources (medicinal herbs, orchids and other horticultural plants).
Today forests extend over about 29% of the land surface, but this is a fraction of the original cover. Historically deforestation in Nepal has occurred over thousands of years (especially in the Mid-Hills), with a sharp increase in recent times following the end of Rana rule in 1950. At that time taxation of arable land provided important revenue, and the state offering tax reductions for three years after clearance for arable land. Under this strong incentive forests disappeared fast in the Mahabharat Mountains and Midlands. Other pressures on timber supply came from increasing demands for charcoal (especially for smelting iron ore) and construction. In 1966 forest cover was estimated at 45%, but between 1979 and 1994 this fell by 9% (NBS 2002), and current annual rates of deforestation are estimated at 1.7%. Quality of forest cover has also declined as shrubland has doubled in area from 4.8% in the mid-1980s to 10.8% in the mid-1990s (Ministry of Population and Environment website).
Two events of the early 1950’s had profound consequences for the forests of Nepal. The first was a change in the legal control of forests, the second was the eradication of malaria in the Terai. Until 1950 forests were governed by a feudal system with general management in local hands following sustainable traditional working practices. In 1957 all forests were nationalised with the Forest Nationalisation Act. This had a devastating effect as it broke the traditional relationship between the community and the forest. There was no compensation for private forest owners and they converted their private forest into farmland to prevent the government from claiming it. Parts of this damaging legislation have now been revoked and some forests (e.g. Community, Leasehold and Religious Forests) have reverted back to local management with good results. Until the 1950’s the malaria-infested belt of thick tropical jungle of the Terai was an effective barrier to marauders from the south, and forest cover was actually promoted to increase the effectiveness of this shield. However, mass migration into the fertile lowlands of the Terai and Siwalik Hills followed the eradication of malaria in the 1950’s, and large areas of the forests were cleared for agriculture.
The current political turmoil in the country is also having negative effects on the forests, particularly in the Terai. Illegal logging and timber smuggling in Protected Areas is controlled by the presence of the Royal Nepalese Army, but with their redeployment to areas of political unrest, and the targeting of ranger posts and forestry official by insurgents, illegal logging is escalating with dramatic effects on the remaining Terai forests.
Forest biological diversity is a priority programme for the Government of Nepal and the main focus for CBD activities. With such high poverty levels in Nepal, encroachment on forest lands for the expansion of agriculture or habitation is understandable. Furthermore, villagers have little alternative to wood for fuel (traditionally wood constitutes over 80% of their energy needs) and about 40% of livestock feed is obtained through lopping of trees for fodder. Although the cutting of trees for fuel is prohibited, this is very difficult to enforce and illegal cutting is rampant. In the moist, broadleaf Eastern forests the under planting of Cardamom (Amomum subulatum) as a cash crop is particularly damaging as although the upper layers of the forest largely remain intact, the natural ground-cover is removed and regeneration is prevented. Conservation has to go hand in hand with poverty alleviation as rural people rely on the wild resources for their very livelihood.

Nepal became signatory to the Convention on Biological Diversity in June 1992 (ratified November 1993). In accordance with this the Government of Nepal has recognised its commitment to the protection and wise use of the biologically diverse resources of Nepal, the protection of ecological processes and systems, and the equitable sharing of all ensuing benefits on a sustainable basis, for the benefit of Nepal’s present and future generations and for the global community as a whole. The CBD places obligations on signatory parties to put in place organisational structures and document their biological diversity and conservation plans. In 2002, Nepal fulfilled one of these obligations with the publication of its Nepal Biodiversity Strategy (NBS 2002), a major landmark in conservation planning in Nepal.
The NBS 2002 sets objectives for the protection of biological diversity in Nepal and identifies or restates Government policy on natural resources and their sustainable use. The Strategy also makes it clear that this is a commitment of the Government of Nepal as a whole, and not of a single ministry. It therefore serves as a guide to all government organisations as well as the private sector and civil society. The Strategy summarises the basic origins to the threats to Nepal’s biodiversity as:
Low levels of public awareness and participation
High population pressures and prevailing poverty
Weak institutional, administrative, planning and management capacity
Lack of integrated land and water use planning
Inadequate data and information management
Inadequate policies and strategies for biodiversity conservation
This Strategy lays the foundation for the production of detailed Biodiversity Action Plans, which are the mechanism through which the Strategy will be implemented. More detailed and updated information can be found on Nepal’s National Biodiversity Unit website.
The Department of Plant Resources (Ministry of Forests and Soil Conservation, MOFSC) is designated as the scientific authority and management authority for wild flora. The CBD National Focal Point for Nepal resides in the Ministry of Forests and Soil Conservation (MFSC), and overall responsibility for the implementation of the NBS (2002) lies within this Ministry.

The National Biodiversity Co-ordination Committee (NBCC) has been set up to facilitate co-ordination during the implementation of the NBS and oversee monitoring and evaluation. The NBCC is a multidisciplinary team comprising about 15 members from various agencies. It will develop policies for consideration by Government and guidance for the implementation of NBS. NBCC will also publish an Annual Biodiversity Report for Parliament and the Nepali People.
A Biodiversity Co-ordinator will be appointed to ensure that the NBCC achieves its goals, policy implementation and direction. The existing National Biodiversity Unit (NBU), established in 1997 under the Environment Division of the MFSC, acts as secretariat to the NBCC, serves as the forum for information exchange, and prepares status reports for the CBD Secretariat every five years. The Biodiversity Co-ordinator will head the NBU.
Five Thematic Sub-Committees (TSCs) will be established to address the five Biodiversity Themes identified in the CBD:
- Forest biodiversity - including protected area ecosystems and species (in-situ and ex-situ)
- Agricultural biodiversity
- Sustainable use of biological resources
- Genetic resources
- Biosecurity
It is envisaged that each of the 75 districts of Nepal will have a District Biodiversity Committee (DBC), chaired by the Distric Development Committee chairperson with representation from the Village Development Committees.
Government of Nepal has been aiming to set up a Nepal Trust Fund for Biodiversity since 1996 as an autonomous body (independent of the Government) to support conservation education, training, applied research, sustainable income-generating activities, anti-poaching control, women-focused programmes, indigenous knowledge and practices and policy development in accordance to national priorities identified in the NBS.
However, it is recognised that the network of protected areas needs to be extended, particularly for the ecologically important Mid Hills where only 1.4% of the land surface is currently included in a protected area. The Mid Hills have the greatest ecosystem diversity in Nepal, but this is under great strain as these lands support about 45% of the population, and the remnants of relatively undisturbed areas are seriously threatened. Initiatives with China and India for the development of a transboundary protected area system are also under way (e.g. around Kanchenjunga, see ICIMOD website), with the view to support corridors and connectivity between protected areas.
The administration and management of protected areas is undertaken by the Department of National Parks and Wildlife Conservation (for Annapurna and Manaslu Conservation Areas the direct management is by a national NGO - the King Mahendra Trust for Nature Conservation, Conservation action: towards a plant red data book
