Harmony in nature: understanding the cultural and ecological aspects of plant use in Ladakh

BACKGROUND

Traditional knowledge (TK) in Ladakh encapsulates a repository of experimental wisdom cultivated over millennia. Despite this cultural wealth, dwindling interest among the younger generations in the region's age-old practices underscores the urgency to document TK. The current study investigates the diverse usage of plants in Surru, Wakha and Lower Indus valleys of Western Ladakh exploring the influence of socioeconomic and ecological factors.

METHODS

A stratified random sample approach was adopted to select 540 respondents for gathering information of useful plants through interviews and questionnaires. Participant observation, questionnaires, open-ended and semi-structured interviews were conducted for data collection. Free listing was done to create an extensive list of plants and their uses. Ethnobotanical metrics such as relative frequency of citation (RFC), relative importance index (RI), cultural value (CV) index and cultural importance (CI) index were computed to assess species applicability. Additionally, one-way analysis of variance (ANOVA) was utilized to discern significant differences in knowledge levels based on valleys, gender, education and religion using TK as a response variable.

RESULTS

Altogether, we recorded 246 plant species under various ethnobotanical uses from Western Ladakh. These include medicinal (126), fodder (124), wild ornamentals (86), food (81), fuel wood (54), dye (20), religious (31) and others (34). Novel plant reports include Berberis brandisiana Ahrendt and Dactylorhiza kafiriana Renz. The dominant plant family is Asteraceae with 35 species. Suru valley exhibits the highest number of cited plants followed by Wakha-chu and Lower Indus valleys (192, 168 and 152 species, respectively).

CONCLUSION

Disparities in plant use understanding are evident among different groups, prompting further investigation through intercultural comparisons. Plants such as Arnebia euchroma, Juniperus semiglobosa, and Artemisia species emerge with cultural importance. Gender, valley affiliation, religious background and the remoteness of a village all influence local plant knowledge. These variations are linked to socioeconomic disparities among communities.

On the rediscovery of a rare root parasite Gleadovia ruborum Gamble & Prain (Orobanchaceae) from Uttarakhand, western Himalaya, India

Gleadovia ruborum Gamble & Prain (Orobanchaceae), a rare root parasite is recorded after a gap of 57 years from a new locality in Uttarakhand, western Himalaya.  A total of four individuals were located in a shady moist forest of Abies pindrow-Quercus floribunda at Surkanda hill near Mussoorie.  All the individual plants were growing on the roots of Rubus pedunculosus D. Don.  The current communication provides an updated description, habitat characteristics and host species of Gleadovia ruborum.

Tawny Fish-Owl (Ketupa flavipes Hodgson, 1836): A new record from a sacred grove in Zemithang Valley, Arunachal Pradesh

Individuals of Tawny Fish-Owl (Ketupa flavipes) were sighted and photographed in a sacred grove in Zemithang, Tawang district, Arunachal Pradesh during nine months fieldwork between June 2017 and February 2018. Previous records from ebird have only listed the occurrence of Tawny Fish-Owl from Pakke Tiger Reserve, Arunachal Pradesh. The present sighting is the first photographic evidence from Tawang district in Western Arunachal Pradesh. The record shows the importance of sacred groves in the conservation of wildlife, which is threatened due to an upcoming hydroelectric power project in the area.

Flora of Niti Valley: a cold arid region of Nanda Devi Biosphere Reserve, Western Himalaya, India

Located in the extended buffer zone of Nanda Devi Biosphere Reserve in Western Himalaya, Niti valley represents a cold arid region. The reserve has been extensively surveyed in terms of floral diversity by various workers, albeit highly confined to the core zones. The current survey recorded 495 species belonging to 267 genera and 73 families of vascular plants through systematic collection in the years 2011, 2012 and 2014. Of the recorded species, 383 were dicots, 93 monocots, 9 pteridophytes and 10 gymnosperms. Asteraceae was most diverse family (32 genera with 58 species), followed by Poaceae (22 genera with 41 species), Lamiaceae (15 genera with 19 species) Fabaceae (14 genera with 22 species), Brassicaceae (12 genera with 12 species) and Rosaceae (11 genera with 36 species). The present survey also updates the existing flora of Nanda Devi Biosphere Reserve (801 species) with addition of 167 species. This study reveals that the Niti valley forms a transition zone, as the floral elements have affinity with Trans as well as Greater Himalaya.

A note on transhumant pastoralism in Niti valley, Western Himalaya, India

Pastoralism plays an important role in the ecology of alpine habitats and the economy of rural people in some regions of India. The pastoralists move from lower altitudes of the Himalayas to higher alpine regions in summer and return back to lower altitude villages with the onset of autumn. The forested areas along the routes of transhumant pastoralists are affected by anthropogenic pressures, viz. grazing by livestock and tree lopping by the herders for fuelwood. To demarcate such areas and evaluate the effect of anthropogenic disturbances, a preliminary documentation of the routes is needed. Interviews were conducted using semi-structured questionnaires to elucidate the information from herders visiting Niti valley, Western Himalayas. The interviews found that most of these herders had common stopovers following a similar route to the valley from their respective villages. More than 70% of herders made their transit camps at Niti village and adjoining areas. They stay there for a few days and then the majority move on to higher alpine pastures of Geldung. The rest either stay back at alpine areas near Niti or in the alpine areas adjoining Gamsali village. These stopovers are areas which experience maximum anthropogenic pressure during livestock migrations, and the vegetation is the most affected. Documentation of migration routes will help identify such areas of high pressure and develop management plans to minimize the disturbances.

Forage selection by Royle's pika (Ochotona roylei) in the western Himalaya, India

Forage selection decisions of herbivores are often complex and dynamic; they are modulated by multiple cues, such as quality, accessibility and abundance of forage plants. To advance the understanding of plant-herbivore interactions, we explored foraging behavior of the alpine lagomorph Royle's pika (Ochotona roylei) in Kedarnath Wildlife Sanctuary, India. Pika bite counts on food plants were recorded through focal sampling in three permanently marked plots. Food plant abundance was recorded by traditional quadrat procedures; forage selection was estimated with Jacob's selection index. Multiple food-choice experiments were conducted to determine whether forage selection criteria would change with variation in food plant composition. We also analyzed leaf morphology and nutrient content in both major food plants and abundantly available non-food plants. Linear regression models were used to test competing hypotheses in order to identify factors governing forage selection. Royle's pika fed primarily on 17 plant species and each forage selection decision was positively modulated by leaf area and negatively modulated by contents of avoided substances (neutral detergent fiber, acid detergent fiber, acid detergent lignin and tannin) in food plants. Furthermore, significance of the interaction term "leaf size × avoided substance" indicates that plants with large leaves were selected only when they had low avoided substance content. The forage selection criteria did not differ between field and laboratory experiments. The parameter estimates of best fit models indicate that the influence of leaf size or amount of avoided substance on pika forage selection was modulated by the magnitude of predation risk.

Changing aspects of traditional healthcare system in western Ladakh, India

ETHNOPHARMACOLOGICAL RELEVANCE

The Sowa-rigpa system of traditional healing has been practiced from time immemorial in western Ladakh but its existence is in jeopardy today. Documentation of information on various aspects of this system such as treatment methods, materials used for medicine and socio-cultural aspects is needed to ensure the long-term survival of this system.

MATERIALS AND METHODS

Extensive field surveys were conducted from March 2009 to June 2011 in three different Valleys of the Kargil district. Interviews with traditional healers, village heads and local people were conducted using semi-structured questionnaires and participatory observations to assess the current status of traditional medicine system. Plant specimens were collected from the field for identification and herbarium preparation which were later deposited in herbaria for future reference.

RESULTS

160 plants were recorded to be used by traditional healers of Western Ladakh. Traditional healing system (THS) is taking care of 30% of public healthcare. Only 36 traditional healers are left in this region of which 67% was found along the Wakha-chu Valley, followed by the Lower Indus Valley (17%) and the SuruValley (16%). The transfer of knowledge to the next generation is very low (25%) in Kargil. Low income and continuously deteriorating social status of healers has contributed to the decline of this system.

CONCLUSIONS

Lack of interest in young generation in adopting this system may pose a threat to the survival of Sowa-rigpa. Integration of this system with the modern healthcare system and more government support may prove effective to enhance its deteriorating conditions.

Floral diversity of Baanganga Wetland, Uttarakhand, India

Baanganga wetland, a 45 km long channel originates near Bishenpur and flows in Idrishpur-Chakheri forest block of Haridwar district in Uttarakhand, India represents riverine ecosystem. The study area harbors many islands, varying in shape and size, which remains underwater during the rainy season and provide a good habitat to various plant taxa, birds (resident as well as migratory) and animals mainly Swamp deer (Cervus duvauceli duvauceli), a critically endangered species and Hog deer (Axis procinus). To asses the status and distribution of flora, trips were conducted in the intensive study area. The plants were classified based on their habit and their presence was visually observed. A total of 178 plant species were recorded, of which 40 species (hydrophytes) were found in aquatic habitat, 122 species on moist shores and 117 species in upland habitat. Phragmites karka, Polygonum barbatum, Ipomoea carnea, and Typha elephantina were the most common species in all the habitats. The majority of plants (40) are from Indian oriental region. The moist shore and upland habitats had maximum similarity (64 %) followed by aquatic and moist shore (26%) habitats. The status of flora and management of Baanganga wetland ecosystem has been discussed in the paper.
