A cross-cultural study of high-altitude botanical resources among diverse ethnic groups in Kashmir Himalaya, India

Plant composition and distribution patterns

We recorded 46 species belonging to 25 different families used by the local people from four ethnic groups (Gujjar, Bakarwal, Pahari, and Kashmiri) of Kashmir valley (Table 2). The number of plant species identified in the research area was comparable to that found in past ethnobotanical investigations conducted in other Himalayan regions. For example, Barreda et al. [48] reported 53 plants from Monpa tribe in Eastern Himalayas; Mir et al. [9] reported 32 pants species from different ethnic groups of Kupwara, Kashmir Himalayas; Asif et al. [22] reported 29 species from various ethnic groups from remote tehsil (Karnah); Sher et al. [49] reported 53 plants from District Swat, Pakistan.

The distribution of species across 25 families was disproportionate, with 7 families (Asteraceae, Ranunculaceae, Apiaceae, Caprifoliaceae, Polygonaceae, Gentianaceae, and Lamiaceae) accounting for about half of the species and 18 families accounting for the other half, including 13 families represented by single species. The species family relationship is shown in Fig. 2. The dominant families were Asteraceae and Ranunculaceae (11% each) followed by Caprifoliaceae (7%) (Table 2). Asteraceae was found dominant in many biomes, primarily in open habitat ecosystems [50]. Several studies have concluded that the Asteraceae was also the most important or useful family in the surrounding areas of Pakistan and Kashmir Himalayas [9, 51, 52]. Likewise, [53] also reported Asteraceae as a dominant family in the Highlands of Gasa District, Bhutan. Ranunculaceae was the second leading family in our study area. Kayani et al. [54] also reported Ranunculaceae as a leading family from the high-altitude of Pakistan. Because of their alkaloids, sterols, flavonoids, and glycosides, plants in the Asteraceae and Ranunculaceae are known as a rich source of medicinal products used to treat a variety of ailments [55, 56]. Furthermore, the current study discovered that families had unequal distribution patterns, with 13 monotypic families, it agrees with earlier ethnobiological research from other Himalayan areas [20, 22].

Traditional cultural use categories

The most common use of plants was for medicine (72%) followed by food (14%) and fodder (5%) (Table 2). This suggests that the high-altitude plant resources are significant in all facets of life for those who reside in remote areas, especially in terms of providing for their fundamental needs in terms of food, shelter, livelihoods and healthcare. Several other studies also reported similar results from other Himalayan regions like [20] from District Reasi, Northwestern Himalaya, [57] from Kashmir Himalayas [14], and from high-altitude Trans Himalaya. People often prefer to use traditional medicine because it is widely available locally, less expensive, has few perceived side effects, its accessibility, and simplicity in administration, and there is a growing importance of medicinal plants commonly used in folk medicine [58]. However, many species may fail to pass clinical testing due to their toxicity and biocompatibility issues.

Parts used

Different parts of plants were used with a significant difference (χ2 = 90.587, df = 7, p < 0.001). Rhizomes were most utilized (45% of uses), followed by leaves (31%) and fruits, flowers, and seeds (5% each) (Fig. 3). Rhizomes are widely used in pharmaceutical preparations due to their high concentration of bioactive components [11]. Similar findings were reported by various ethnobotanists including [9] from Kashmir Himalayas, [59] from Northern Ethiopia, and [2] from tribal communities in the Western Himalaya. Excessive use of rhizomes, particularly in the case of threatened species, should be avoided because it can have a detrimental impact on population and growth, as well as lead to extinction [9]. Leaves might have the potential to be a source of valuable drugs in addition to food. The presence of alkaloids in them explains why they are often employed as a remedy in traditional medicine so efficiently [14].

Form of remedy preparation

In the current study, powder (59%) was the most frequent preparation form, followed by paste (15%) and decoction (14%) (Table 2). Rokaya et al. [60] also reported powder form as the common form used by local inhabitants of Nepal India. The patients regarded powdered preparations as quite effective, and it was utilized whenever possible. Similarly, findings were reported by [61] from Himalayan India.

Diseases cured

A total of 33 aliments were treated with plants, and most species (25%) were employed for gastrointestinal disorders, followed by musculoskeletal diseases (20%) and dermatological problems (12%) (Fig. 4, Table 2). The possible reason behind these results might be that gastrointestinal disorders are common in these areas due to a lack of hygienic conditions, malnutrition, and a lack of pure water. Similar results were reported by [62] and [12] from Pakistan; [63] from Northern Nigeria; and [9, 35] and [30] from various ethnic groups of Northern Himalaya. Among the uses of plants for medicine, the treatment of gastrointestinal diseases holds a significant role in many regions [64,65,66,67].

Novelty of the study

This study's list of 46 wild plants was cross-checked against 20 published articles from the entire Himalayan region (Table 3). This comparison helped to reveal variances of local wild plants that existed across various populations and places as shown in the Jaccard Index (JI). In the current study, the JI values ranged from 10.87 to 0.64 (Table 3). The highest value was reported from District Kupwara [33; 10.87] followed by the Sindh forest, Jammu & Kashmir, India [36; 9.40], and Kedarnath Wildlife Sanctuary, Himalaya, India [32; 7.03]. Due to similar geographic or climatic conditions, the greater JI score demonstrates the similarity in vegetation types between the two places. The minimum JI was calculated in the study of Bandipora District, Kashmir Himalaya, [44; 0.64], where only 1 similar plant was reported with the current site because there is a significant difference in the geography; the reported site is a mountainous region with low altitude, whereas the current study is a high-altitude mountain region.

Table 3 Jaccard index value for plants

The current study also reports 18 wild species that have rarely been documented for treating human ailments in the ethnobotanical literature: Aconitum violaceum, Angelica glauca, Aquilegia nivalis, Arnebia benthamii, Bunium persicum, Corydalis cashmeriana, Delphinium cashmerianum, Dipsacus inermis, Fritillaria imperialis, Gentiana kurroo, Iris hookeriana, Lagotis cashmeriana, Potentilla nepalensis, Rheum spiciforme, Rheum webbianum, Rhododendron campanulatum, Thymus linearis, and Trigonella emodi. While 28 medicinal plants had already been reported in the available literature, we documented novel utilization for 18 of these species (Fig. 5). The present study reported new uses for 24% plant species, e.g., rhizome of Corydalis govianiana for killing lice in animals, raw roots of Jurinea dolomiaea for tooth cleaning, seeds of Verbascum thapsus for respiratory diseases, leaves of Bergenia ciliata as lid for utensils, flowers of Saussurea simpsoniana were presented to anybody a wish for good luck, leaves of Dipsacus inermis were used for internal injuries and body inflammation, leaves of Arnebia benthamii as brain tonic, leaves of Viburnum grandiflorum against muscle sprain, leaves of Aconitum violaceum used as food, rhizome of Geranium wallichianum as dye, bark of Rhododendron campanulatum to overcome drug addiction, rhizome of Aconitum heterophyllum for stomach problems and piles.

Use value

In the present study, the highest UV of 0.86 was calculated for Aconitum heterophyllum and the lowest UV of 0.26 for Androsace rotundifolia (Fig. 6; Table 2). Due to their widespread distribution and widespread knowledge of therapeutic applications among the local population, medicinal plants in the research location had high UV levels [35, 68, 69].

Cross-cultural analysis

We examined how social, economic, and cultural factors influenced plant resource utilization patterns among various ethnic groups in the region. Across cultural relationships, the Gujjar and Pahari showed greater similarity (17%), whereas the least overlap (2%) was observed between Bakarwal, Gujjar, and Kashmiri (Fig. 7a).

The reason for the greater similarity of Gujjar and Pahari lies in the fact that both ethnic groups share a common geographical landscape, while both are exogamous to each other (Table 1), whereas the Bakarwal, Gujjar, and Kashmiri have different cultural identities, live in different areas of the region, and not surprisingly showed the least relationship. The cross-cultural analysis revealed that all ethnic groups used 14 species on a regular basis followed by nine species shared by the Bakarwal, Gujjar, and Pahari and minimum one species (Saussurea simpsoniana) by Bakarwal, Gujjar, and Kashmiri (Fig. 7b). Meanwhile, Kashmiri was the only ethnic groups with idiosyncratic species (N = 1) Prunella vulgaris, which may be accounted for by the fact that the aforementioned species thrives in habitats near rivers, streams, and canals, which are located at relatively elevations, as well as by the fact that the aforementioned ethnic group use it commonly during COVID-19 to treat cold, fever, and migraine. Many other researchers conducted similar cross-cultural analyses, revealing the overlapping and uniqueness of species due to cultural, landscape, availability, and socioeconomic factors such as [14] from the Trans Himalayas; [25] and [70] from Pakistan Himalaya; [10] and [71] from Kashmir Himalaya; and [72] from Eastern Morocco and Eastern Andalusia.

The Venn diagram can, however, not provide a clear picture of plant usage; for example, if a specific ethnic group uses N plants, it does not specify whether it is used by one informant or by maximum members of that ethnic group. We used indicator species analysis for the first time to solve this problem. The analysis of indicator species revealed a clear distinction between key species in four ethnic groups (Fig. 8). In the Gujjar ethnic group, Aconitum heterophyllum and Dolomiaea costus had significant indicator value, the reason behind this being that these plants grow in abundance near forests and are easily available, and also have a wide range of uses and also support livelihood, while Rhododendron campanulatum and Rheum spiciforme all had significant p values in the Bakarwal ethnic group, because this ethnic group spends the majority of their time in high-altitude pastures, making them frequently use these plant species for medicine, food and fuelwood. Aconitum heterophyllum and Prunella vulgaris were indicator species of the Kashmiri ethnic group, both these species are having the multiple medicine usage (particularly in COVID-19). In the Pahari ethnic group, Fritillaria cirrhosa and Rheum spiciforme were indicator species; all of these species had numerous medicinal uses in addition source of livelihood. The majority of species with high indicator values were associated with particular ethnic communities and heavily consumed by them. Aconitum heterophyllum was a common indicator species between Gujjar and Kashmiri ethnic groups, while Rheum spiciforme was a common indicator species in Pahari and Bakarwal ethnic groups (Fig. 8). The reason was that these plants were frequently used in traditional medicine, and Gujjar and Bakarwal communities primarily extracted them from the surrounding forest area and selling them to the Kashmiri community, which primarily resides in the lower reaches of the Kashmir valley. In this way, information on medicinal usage and means of support are passed from one community to another.

Some of the commonly used plant species used by all four ethnic groups were Aconitum heterophyllum, Angelica glauca, Fritillaria cirrhosa, Rheum webbianum, Dolomiaea costus, and Arnebia benthamii. The reason behind this was that these species were all medicinal and were used in various forms as well as having cultural and traditional values. The ethnomedicinal knowledge of these species was held mostly in the Gujjar, Bakarwal, and Pahari ethnic groups. The Kashmiri ethnic group had less ethnomedicinal knowledge because of the preference for allopathic medicine. People often had to walk by foot about 10–15 km to reach the areas where medicinal plants were collected.

Medicinal plants used by Gujjar and Pahari ethnic groups were Ferula jaeschkeana, Euphorbia wallichii, Primula denticulata and Phytolacca acinosa. The reason behind this great similarity between these two ethnic groups lies in culture, language, and tradition. These ethnic groups live near forests and visit higher altitudes in summer along with their livestock. There were least plant species which used by Bakarwal and Kashmiri ethnic group, given their very limited interactions between these two ethnic groups and their different culture and tradition as well as language. The Gujjar and Pahari acted as knowledge-transferring agents between Bakarwal and Kashmiri ethnic groups. The highest number of plant species was used by Gujjar, Pahari, and Bakarwal ethnic groups. The interaction between these ethnic groups usually occurred in summers in the alpine regions of the study area where all these ethnic groups live together along with their livestock.

Relationship between indicator values and the number of plants used by different ethnic groups

The results showed that the indicator values and the number of plants had a linear relationship (i.e., positive correlation) with the Gujjar (R2 = 0.013, intercept = 20.94, slope = 1.17), Kashmiri (R2 = 1.08, intercept = 23.47, slope = 0.013) and Pahari (R2 = 0.014, intercept = 21.45, slope = 0.94), while the relationship between the number of plants represented a negative correlation with indicator values of the Bakarwal ethnic group (R2 = − 0.022, intercept = 23.39, slope = − 0.049) (Fig. 9).

Our data enabled an investigation into the links between the indicator values of numerous widely used plants with the relative importance of ethnobotanically used species as well as various ethnic groups. The positive connection indicates cultural preferences for certain plant use and underlines the cultural significance of each species. Such positive combinations create the door for their future applications. The highest R2 value for the community showed strong relationships with indicator values of medicinal flora.

Plants and livelihoods

The ethnic people living in the Himalayas have a close relation with the local flora [22]. We recorded 16 plant species (Trillium govanianum, Arnebia benthamii, Aconitum heterophyllum, Aconitum chasmanthum, Dolomiaea costus, Fritillaria cirrhosa, Jurinea dolomiaea, Saussurea simpsoniana, Rheum webbianum, Podophyllum hexandrum, Gentiana kurroo, Angelica glauca, Dolomiaea macrocephala, Bunium persicum, Rheum spiciforme, and Picrorhiza kurroa) being sold by ethnic communities to improve their income, and the traditional health practitioners (Hakeems) also used these species for making medicinal preparations. The ethnic groups with the highest plant use were Bakarwals and Gujjar. Due to strict faith in traditional medicine, the demand of the plant species was very high, hence people earned handsome incomes. If trade of plant species continues at the same rate, it is possible that in various species will vanish from the region the near future, ultimately affecting the biodiversity of the region. In the past, due to high market value, the unchecked exploitation of different species resulted already in the loss of biodiversity and a threat to many species [73, 74].

Plant toxicity

In the present study, local people indicated that Rhododendron campanulatum, Podophyllum hexandrum, Arisaema jacquemontii, Fritillaria imperialis, Euphorbia wallichii and Phytolacca acinosa, besides having medicinal value, did also possess poisonous potential if harvested in the inappropriate stage. Plants with lethal attribution constituted 8.69% of the total documented species.

Different plant parts were reported as responsible for toxicity. For instance, unripe fruits of Podophyllum hexandrum, Arisaema jacquemontii, Phytolacca acinosa, early-stage leaves of Rhododendron campanulatum, immature bulb of Fritillaria imperialis, latex from rhizomes of Euphorbia wallichii. The lethality of the plant/part can often be ascribed to alkaloids present [11, 75]. It is important to note that local people suffered losses in the form of livestock/human deaths as a result of the consumption of these plant species. As a result, our study can be used as a written reference for a safer future utilization of these plant resources.
