BACKGROUND: Medico-ethnobotanical exploration is an important part of drug research, which provides information on the distribution, availability, and natural habitat of medicinal plants. The collection of specimens and photographs during the survey tours acts as the reference materials for the description and characterization of raw drugs and their botanical source to avoid adulteration and substitution. The present study aimed to explore the potential of the medicinal plants of the Almora forest division and their present status in the natural habitat. METHODS: Medico-ethnobotanical exploration was carried out in the Almora forest division of Kumaun Himalayan region in Uttarakhand, India, from July 2018 to February 2019. Almora, Someshwar, Mohan, and Jaurasi ranges of the Almora forest division were explored in different seasons during these surveys. During exploration, herbarium specimens and photographs of medicinal plants, preferably flowering or fruiting twigs, were collected with locality and GPS data. Plants were identified and also referred to the herbarium of the Regional Ayurveda Research Institute, Ranikhet, Uttarakhand, and the published literature. RESULTS: During these surveys, 204 medicinal plant species were documented with their local name and locality(s) with GPS location showing their distribution. Among the 204 identified medicinal plant species of this region, six species are found under the endangered and threatened category. CONCLUSIONS: There is an urgent need for the conservation of medicinal plants and their natural habitat for their perpetual existence. Further, medicinal plants having commercial potential should be cultivated by local inhabitants for their socioeconomic development.

| Introduction|| |
Uttarakhand is one of the hilly states of India situated in the northwestern part of the Indian Himalaya and considered as the “Herbal State.” This region is endowed with medicinal and aromatic plants of tropical, subtropical, temperate, subalpine, and alpine categories. In the Himalayan region, people are still bound to depend on the natural medicinal plants and folk healers/Vaidya for the treatment of various disease conditions. The present study was conducted in different ranges of the Almora forest division of Uttarakhand to explore the potential of medicinal plants of the region and their present status in the natural habitat.
Almora forest division is on the southern edge of Kumaun hills in the Himalayan range in Uttarakhand and is located between 29°30′.08″N and 29°58′.48″ N latitude and 79°04′.18″E and 79°47′30″E longitude. It is surrounded by Kedarnath forest division on the northern side, Bageshwar forest division on the northeastern side, Binsar Wildlife Park and Jageshwar range of Civil Soyam on the eastern side, Nainital on the southern side, Ramnagar and Kalagarh Tiger Reserve forest division on the southwestern side, Kalagarh Tiger Reserve forest division and Garhwal forest division on the western side, and Garhwal forest division on the northwestern side [Figure 1]. It covers an area of 61082.0345 hectares with elevation ranges from 463 m to 2769 metres above sea level. It enjoys varying climate and soil conditions in its different parts from Tarai to the temperate with a variety of flora.
The climate of the division is extremely varied, because of the variation in the altitude and topography. The valleys are hotter during summer and cold during winter, whereas in hilly areas, summer is pleasant and snowfall occurs during winter above 1600 m. The temperature of the region ranges between 38°C and −5°C. Rainy season starts from mid June and ends in mid September. It has an average rainfall of 960.6 mm. The vegetation is dominated by pine forests, followed by oak and rhododendron forests, etc.
| Materials and Methods|| |
Four medico-ethnobotanical surveys (MEBS) were conducted in Almora, Someshwar, Mohan, and Jaurasi forest ranges of the Almora forest division and its adjoining areas in different seasons. The survey team comprised one botanist, one Ayurvedic physician, and a field staff.
During the first survey, the areas of the Almora forest range, viz., Shimtola, Basoli, Gananath, Jangarkhan, Amkholi, Kangarchina, Kafarkhan, Latwalgaon, Kosi, Chitai, Dhaulchhina, Deenapani, Doba, Shitlakhet, Shyahi Devi, and Dhamas, were explored from July 23 to July 30, 2018. In the second survey, the areas of Someshwar forest range, viz., Someshwar, Kausani, Aeridhau, Pinnath, Pandukholi, Lodh, Gagas, and Rudradhari, were surveyed from October 11 to October 17, 2018. During the survey of the Mohan forest range, Kumeria, Ghugutidhar, Kijari, Bakule, Simtaya, Charidhar, Panuadhyokhan, Ghati, Pathoria, Jumeria, Chandkichod, Tolyun, Kathkinao, and Bhatrojkhan areas were explored from January 19 to January 25, 2019. In the survey of the Jaurasi forest range, Pasoli, Jaikhal, Buranspani, Bhanglwari, Kathpatiya, Gular, Dotiyal, Manila, Malekuda, Bajkhet (Shyalde), Jhimar, Mulekhal, Dudhlia, Songaon, and Khadaktiya areas were surveyed from February 22 to February 28, 2019.
Field survey and data collection
During these surveys, standard field and herbarium methods were followed. Herbarium specimens preferably flowering/fruiting twigs were collected along with photographs of medicinal plants. The local name, locality, and GPS data were also recorded as per the methodology suggested by the CCRAS, Ministry of Ayush, Government of India. The plant specimens collected during the field surveys were identified with the help of regional floras, by matching with the specimens available at the herbarium of Regional Ayurveda Research Institute (RARI), Ranikhet, Uttarakhand and also with the published literature by the taxonomists.,, The voucher specimens and herbaria of the collected species were preserved in the herbarium of the RARI, Ranikhet, Uttarakhand.
Further, the details of local traditional healers in the survey area were collected from the range officers, village head, villagers, and indigenous people. Open-ended interviews of the folk healers were conducted to collect the data in a semi-structured questionnaire format. All interviews were conducted after taking informed consent from the informants.

During these four surveys, a total of 204 species of medicinal plants were recorded from the survey areas. The details of these plant species were further systematically compiled incorporating botanical name (in alphabetical sequence), family (in parenthesis), Sanskrit name (if available), local name, habit, and locality with GPS location [Table 1], [Figure 2].

The documented medicinal plants belong to herbs (44%), small and large trees (25%), shrubs and under shrubs (20%), climber (8%), epiphyte, and mushroom (2%) [Figure 3]. Among the 204 identified medicinal plant species of this region, six species were found under the endangered and threatened category. Their status as per the Foundation for Revitalisation of Local Health Traditions (FRLHT) is shown in [Table 2].

During this exploration of the Almora forest division, it was observed that medicinal plants are depleting to a great extent because of the forest fire, overexploitation, overdominance of pine forest, and a lack of the conservation measures. As per the observation of the National Medicinal Plants Board, Ministry of Ayush, Government of India, there is an urgent need for the conservation and domestication of endangered and threatened medicinal plant species. In addition, initiatives such as the promotion of Medicinal Plants Conservation and Development Areas (MPCDAs) in different state forest divisions of India should be encouraged. The survey team visited one such MPCDA at Mohan, Almora, Uttarakhand, India, developed by the state forest department in collaboration with the United Nations Development Programme (UNDP). The Almora forest division has a good potential for the development of more such MPCDAs in the suitable forest areas.
| Conclusions|| |
The result of this exploration highlighted the herbal potential of the Almora forest division, Uttarakhand, India. However, it is needed to create awareness among the local people regarding conservation and cultivation of medicinal plants. Further, the medicinal plants having significant commercial potential should be cultivated through the local inhabitants for their socioeconomic development.
