Mountain ecosystems all over the world support a high biological diversity and provide home and services to some 12% of the global human population, who use their traditional ecological knowledge to utilise local natural resources. The Himalayas are the world's youngest, highest and largest mountain range and support a high plant biodiversity. In this remote mountainous region of the Himalaya, people depend upon local plant resources to supply a range of goods and services, including grazing for livestock and medicinal supplies for themselves. Due to their remote location, harsh climate, rough terrain and topography, many areas within this region still remain poorly known for its floristic diversity, plant species distribution and vegetation ecosystem service.
The Naran valley in the north-western Pakistan is among such valleys and occupies a distinctive geographical location on the edge of the Western Himalaya range, close to the Hindu Kush range to the west and the Karakorum Mountains to the north. It is also located on climatic and geological divides, which further add to its botanical interest. In the present project 120 informants were interviewed at 12 main localities along the 60 km long valley. This paper focuses on assessment of medicinal plant species valued by local communities using their traditional knowledge.
Results revealed that 101 species belonging to 52 families (51.5% of the total plants) were used for 97 prominent therapeutic purposes. The largest number of ailments cured with medicinal plants were associated with the digestive system (32.76% responses) followed by those associated with the respiratory and urinary systems (13.72% and 9.13% respectively). The ailments associated with the blood circulatory and reproductive systems and the skin were 7.37%, 7.04% and 7.03%, respectively. The results also indicate that whole plants were used in 54% of recipes followed by rhizomes (21%), fruits (9.5%) and roots (5.5%).
Our findings demonstrate the range of ecosystem services that are provided by the vegetation and assess how utilisation of plants will impact on future resource sustainability. The study not only contributes to an improved understanding of traditional ethno-ecological knowledge amongst the peoples of the Western Himalaya but also identifies priorities at species and habitat level for local and regional plant conservation strategies.
- Biodiversity conservation
- Ecosystem services
- Medicinal plants
The benefits obtained by humans from nature are termed as Ecosystem Services [1, 2]. Natural ecosystems provide human societies with vital supporting services, such as air and water purification, climate regulation, waste decomposition, soil fertility & regeneration and continuation of biodiversity. The Millennium Ecosystem Assessment (2003) and few other studies of ecosystem services have classified these services into four broad categories – provisioning, regulating, supporting and cultural [3–8]. These services are produced by complex interactions between the biotic and abiotic components of ecosystems. All kinds of ecosystem services, whether provisioning, regulating, supporting or cultural, are closely allied to plant biodiversity [9, 10]. All sort of these services ultimately contribute to agricultural, socio economic and industrial activities [11–13]. Plant biodiversity on slope surfaces of the mountains regulates supply of good quality water and prevents soil erosion and floods. It also enhances soil formation, fertility, nutrient and other biogeochemical cycling. Provisioning services provided by plant biodiversity are in the form of food, grazing land and fodder for their livestock, fuel wood, timber wood, and medicinal products. Culturally, people utilize plants in number of ways like aesthetics, religion, education, naming etc.
People extensively utilize the predominant herbaceous flora of mountainous ecosystems by keeping cattle and multipurpose collection, both of which cause over-exploitation of the vegetation and risks to the continuation of plant biodiversity. In order to develop appropriate systems for the sustainable use of plant resources, it is crucial to understand how traditional uses of plants influence biodiversity in these ecosystems. A plant that possesses therapeutic properties or exerts beneficial pharmacological effects on the human or animal body is generally designated as “medicinal plant”. It has also been recognized that these plants naturally synthesize and accumulate some secondary metabolites, like alkaloids, glycosides, tannins, volatile oils, minerals and vitamins, possess medicinal properties [14, 15]. A number of medicinal plants possess some special characteristics that make them special in those mountainous regions of the Himalayas and adjacent ranges [16, 17]. Medicinal plants constitute an important natural wealth of that region and ultimately at national level. They play a significant role in providing primary health care services to rural people . They serve as healing agents as well as important raw materials for the manufacturing of traditional and modern medicine . Similarly a substantial amount of foreign exchange can be earned through exporting medicinal plants to other countries. In this way indigenous medicinal plants play significant role of an economy of a country. This paper therefore, sought to, not only studies the natural vegetation of the Naran Valley, but also to the indigenous people of the valley in an assessment and identification of the plant species of therapeutic uses.
Methodology for ethnobotanical data collection and analyses
Observations of local people during first fieldwork (summer, 2009) about the utilization of plant biodiversity for various purposes were used for the questionnaire preparation. A mixture of qualitative and quantitative methods of data collection was adopted in preparing a questionnaire for collecting indigenous knowledge about plant species. Local names of plants were listed along with the botanical names of the recorded 198 plant species [21, 22]. Plant species photographed during the first field campaign were shown to the interviewees where and when it was felt necessary.
Each of the main 12 localities (A-L) in the project area (at an interval of about 5 km each), where vegetation transects had been taken, were revisited (Figure 1). Meetings were arranged with village heads or councillors and permission as well as guidance was obtained. Ethnic groups including the Gujars, Syeds, Swati and Kashmiri inhabit the valley. The most important among these are the Gujars (descendents of the Indian Arians) who are famous for their unique culture, way of life, rituals and bravery. The Gujars are concentrated in the upper parts of most valleys in Pakistan where they cultivate rain-fed slopes, and are generally more aware of traditional knowledge, of plant use and local ecology. A local community member of these tribes was taken as a guide who knew the norms and traditions of that indigenous society [23, 24]. Ten houses at each of the 12 main localities of the Valley (a total of 120) were selected randomly for the interviews, using a random number table. Each village was visited from one side; a coin was tossed in front of each 5th house and if it fall head side up, then an interview was requested from that family [24, 25]. If willing, one member in the household was interviewed about their uses of plants, preferences, therapeutic application and plant part that were used. Informants were asked about their general uses of plant species, e.g. as food, fodder, grazing, timber, fuel, aesthetic, medicinal and others. Respondent were then asked about their species preference if they utilised a species for several purposes – food, fodder, grazing, fuel, timber or medicinal purposes. As there was much preference for medicinal uses of plants and hence informants were further asked for details about the plant part(s) that were used, the diseases it cured and the recipe of use.
Questionnaire data was initially analyzed for basic categorization of the respondents’ gender, age groups and literacy ratio etc. This data was additionally analyzed for use preferences, plants parts used, recipes and treatment categorization with slight changes to the methodology adopted by [26–28].

Plants’ parts used and their preparation
Role of native plants in supporting human livelihoods and well being
Findings of this paper signify the relationship between the provisioning ecosystem services of vegetation and human well-being in the study area. The questionnaire analyses indicate that the people of the Naran Valley possess valuable knowledge of natural plant biodiversity and the services it can provide are immensely important to them. There was a variation in knowledge at individual level depending upon the relation between the person and the specific plants species or group which he/she prioritizes for certain uses which is reported in number of other studies also [29, 30]. Nevertheless, this study has been able to demonstrate that plants are used to support a wide range of livelihood activities in the study area, and particularly as a source of traditional medicines. Furthermore, plant biodiversity of the region provide timber, fuel, medicines, food, fodder, grazing and others services to the indigenous communities. However extensive uses of natural vegetation in the past have decreased the provisioning services. Local residents especially the older generation prefer to live in the valley because of the existing provisioning ecosystem services and their traditional ethno-ecological knowledge. However, the new generation tend to leave those rural spaces in search of education, facilities and easy modern life .
Medicinal plant resources
The use of plants to cure diseases is as old as human history. Around 20% of the plant species of the world are estimated to be used in health care systems . Medicinal plants play an important role in the traditional health care systems of this region also. A few of the species found in the region, i.e. Dioscorea deltoidea, Podophyllum hexandrum, Berberis pseudoumbellata, Cypripedium cordigerum and Dactylorhiza hatagirea, are listed on the CITES appendix II (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). One or more of these species were also reported in few other studies from other Himalayan and the Hindu Kush areas [17, 33]. Some other medicinal species are endemic to the Himalayas and hence should also be given attention in order to ensure sustainable use e.g., Cedrus deodara and Aesculus indica, whilst some are rare in the region e.g., Aconitum heterophyllum, Aconitum violaceum, Ephedra gerardiana, Hypericum perforatum, Indigofera heterantha, Paeonia emodi, and Ulmus wallichiana. In addition to medicinal uses, these species provide other services like timber fuel and grazing etc. Numbers of the remote valleys in the Himalayas have not been studied specifically for the ecosystem services and plant medicinal uses though indigenous inhabitants of these areas have a long established system of health care and cure with available medicinal plant resources. The elder people have more accurate knowledge about the parts and recipes than the young which improve the effectiveness of medicinal plants. Similar trend was also reported by other ethnobotanists in the Southern Ethiopia and Hindu Kush region [34, 35]. It is important to recognise that unsustainable collection of medicinal plants is one of the main causes of plant population decline. Increasing human population, extensive grazing, habitats losses, multipurpose collection and carelessness are the other factors. All such ecological as well as cultural matters need to be documented and addressed while designing management, preservation and conservation strategies. Results of this paper also demonstrate that most of the plants are either used as a whole or its parts like roots and rhizomes distinctively which are also alarming signals against the sustainable use of this highly valued plant biodiversity. In addition marketing of certain species indicate probable threats information about their conservation which also suggests that number of these economically important species can be domesticated and propagated in protected places for marketing purposes. Interestingly, most of the less abundant species and families are utilized frequently by the locals. For example, 31 small families with only 1 or 2 species are all used medicinally in the area. These findings not only prove that peoples utilize the plants according to their traditional knowledge and not their abundance but also indicate the rarity of such taxa in the near future.
Indigenous knowledge as a cultural asset
Rapid technological and economic development has brought ecological and social changes all over the world. Cultural changes even take place in remote rural societies due to their increasing interactions with modern urban cities. Subsequently, knowledge about the use of plant resources, as well as the plant wealth itself, is declining in a number of regions [36, 37]. The present study also reveals a decrease in indigenous knowledge and changes in attitudes regarding health-giving flora among the younger generation. This phenomenon is confirmed from the study of  on the Pakistani migrants in Bradford UK. This and other similar studies, further communicate the extinction of traditional knowledge in modern societies. Indigenous people, although the possessor of traditional knowledge have no proper training in sustainable ways of plant collection, post collection care and processing and usually waste a considerable amount of medicinal plants. Such sort of unwise practices over a long time can cause a reduction in plant biodiversity in general and of plant species providing provisioning services in particular [39, 40]. It is therefore, suggested to recruit ethno-ecologists and experts to train the local people for the sustainable utilization of medicinal plant resources. Some of the problems associated with medicinal plant resources can be overcome through research on domestic growth of medicinal plants and development of processing techniques among the people. In this recent millennium, present and number of other research studies suggest urgent call for the preservation of both long-established remedial knowledge and medicinal plant resources in the developing world, particularly in the Himalayas [17, 41–44]. Furthermore, long-established knowledge about the medicinal values of plants has contributed a lot in the past in production and synthesis of synthetic drugs and market values. It has played and still plays a remarkable role in solving health related problems especially in undeveloped and remote parts of the world. A number of issues were identified during the present project. These include documentation of the traditional knowledge; intellectual property rights of the locals, trainings about the sustainable use of the available resources and use of the traditional knowledge for conservation which can be addressed in the future.
Inhabitants of the Naran Valley are highly acknowledged for participation in interviews and sharing their ethnomedicinal knowledge.
