Ethnoarchaeology of Pastoral Transhumance in Kashmir Himalayas

Despite immense ethnographic and archaeological potential, nomadic pastoralism finds not much attention from an ethnoarchaeological perspective in India. The ethnoarchaeological survey was thus undertaken among the contemporary pastoralist tribe of Bakarwal in the Kashmir Himalayan region to aid in the development of a diachronic model for seasonal transhumance. From this study, it is suggested that pastoralist communities in the northwest Himalayas retained flexible ethnic identities, dynamic settlement and subsistence patterns, and maintained trade and exchange relationships with adjacent groups over the historical period. The ethnoarchaeological analysis of Bakarwal sites in the Kashmir Himalayas has demonstrated that these sites’ structure, geographical positioning and functionality provide critical information concerning the exploitation of the landscape by the pastoral groups.

Western disturbances alter the trend of winter precipitation and its extremes over Northwest Himalayas: Kashmir Himalaya.

The perception of spatio-temporal variability of winter precipitation covering dominant water resources and environment over Kashmir Himalaya is a pre-eminent perspective under current social interests. The main objectives of the study are, firstly, to unriddle the whole (1980-2020) and post-2000 trend in the winter season precipitation (WP), frequency of low-pressure systems (Lp-S), and western disturbances (WDs) to understand the footprints of climate change over the region; secondly, to evaluate the spatio-temporal variability of winter precipitation under the dominance of global teleconnection indices, using both station and reanalysis datasets. Modified Mann-Kendell test and a linear regression model were utilized to extract the trend and significance in WP, Lp-S, and WDs. The results reveal that WP shows an insignificant decreasing trend (1980-2020), with an increasing trend post-2000, while a decreasing trend is seen during post-2000 in the frequency of Lp-S and WDs. The contribution of WP to annual precipitation shows decadal variability with a decreasing trend post-2000. The anatomy of winter extreme precipitation days has shown a decreasing trend (1980-2020), with a robust coupled increasing trend with WP post-2000. The dynamics of ten severe WD-based extreme precipitation events show that a cyclonic circulation and trough connects the Arabian Sea and the Himalayas, bringing additional moisture to the study region and resulting in extreme precipitation. The cogency of global teleconnections on the variability of WP shows that a pattern with positive phase of NAO, ENSO, and a negative phase in Siberian high intensifies the WD-based precipitation. The study discovers its applicability for the regional forecast system in predicting the winters.

Assessing ethno-veterinary practices in Kashmir Himalayas: Traditional knowledge and its role in animal healthcare

This study was aimed at exploring the ethno-veterinary practices in the District of Kupwara in Jammu and Kashmir Union Territory of India, by examining the traditional knowledge and its application in animal healthcare. The study included qualitative methods, such as interviews with local farmers (n=100) and traditional healers, as well as observation of their practices from February to April 2023. The results revealed a rich knowledge base among the local community regarding the use of medicinal plants for treating a range of animal ailments. 32 plants of pharmaceutical value representing 23 families have been assessed, with the Asteraceae family receiving the greatest attention. Eighty-eight percent of these ethnoveterinary medicinal plant species were herbs. Leaves of these plants were used most often (27%), followed by the entire plant (21%), seeds (21%), roots and fruits (9%), bulbs (6%), and stems and rhizomes (3%). Glycine max (0.91) and Allium sativum (UVi = 0.89) had the highest UVi values, whereas Oryza sativa (0.51), Allium sativum (0.49), and Zea mays (0.43) were the most cited and most often mentioned therapeutic plant species. Traditional veterinary practices were found to be deeply embedded in the local culture and were passed down through generations of farmers and traditional healers. These practices are still widely used today, in combination with modern veterinary medicine, to provide comprehensive care to livestock in the region. This study highlights the importance of preserving and promoting ethno-veterinary knowledge and practices as a valuable resource for animal healthcare in rural communities.

Vegetation and soil ecology of threatened Himalayan Trillium habitats in Kashmir Himalaya

Understanding the vegetation and soil ecology of natural habitats harbouring threatened species is critical in conservation planning and restoration. The present study investigated the vegetation composition and soil physico‐chemical properties of natural habitats of Trillium govanianum – a threatened Himalayan endemic species. We laid 120 quadrats across eight randomly selected sites where the species was growing in the Kashmir Himalaya. We collected the soil samples from these sites and determined soil physico‐chemical properties using standard methods. Across all the sites, we found a total of 57 plant species with dominance of Rosaceae and Ranunculaceae. The importance value index (IVI) results revealed that Fragaria nubicola, Corydalis diphylla, Galium aparine, and Leucanthemum vulgare, were the dominant species in T. govanianum habitats. The density, abundance and IVI of three‐leaf vegetative plants was higher than one‐leaf vegetative and three‐leaf reproductive plants across all the study sites. We found that T. govanianum alone forms 23.5% positive, 0 negative, 76.4% random co‐occurrences with other associated species in its habitats. Our results reveal that the variations in vegetation composition among the sites was influenced by differences in soil properties. Principal component analysis (PCA) revealed that several soil properties such as organic carbon (OC), nitrogen, potassium, and sulphur were concentrated in five sites, namely Dara, Drung, Bangus, Gulmarg and Doodhpathri, which also showed the highest density, frequency, and abundance of T. govanianum. Overall, our study contributes quantitative information on the vegetation and soil ecology of T. govanianum‐habitats, which in turn can help in developing conservation strategies for this threatened species, and its sustainable management and habitat restoration.

Status of Biodiversity in a Protected Area of Kashmir Himalaya: Gulmarg Wildlife Sanctuary

The present study attempts to comprehensively study the floristic elements of Gulmarg Wildlife Sanctuary (GWLS), Kashmir Himalaya. During the present study 364 species of vascular plants belonging to 227 genera and 74 families were recorded from the sanctuary. A total of 18 communities (10 within forest and 8 within alpine zone) were identified. Forest zone of the sanctuary was represented by shady moist, dry, bouldery, rocky, riverine and exposed habitats; whereas the alpine zone was represented by bouldery, riverine and moist and exposed habitats. Of the total 364 reported plant species, 161 species were native to Himalayan region and the remaining i.e. 203 species were non‐natives. Out the total 161 native plant species, 82 were endemic to the Himalayan region. Further, 22 plant species were having threatened status in Jammu and Kashmir. Major threats to biodiversity within the sanctuary include overexploitation, habitat degradation, overgrazing, invasive species, human settlements, huge tourism influx and pollution. In the present study, based on the 'conservation priority index' (CPI) of the plant species, 51 plant species were assessed to be threatened in GWLS. Further, maximum CPI of dry and shady moist habitats and Aesculus indica–Pinus wallichiana mixed and Taxus wallichiana–Prunus cornuta–Aesculus indica mixed communities reveals that proper management of these prioritized habitats and communities would help in maintaining the natural ecosystems and conservation of species of the sanctuary. Present study recommends that awareness about the values of biodiversity for sustenance through organization of training workshops, awareness camps need to be created among the local inhabitants as well as visitors. Further, no in‐depth explorations for community characterization of forest and as well as alpine ecosystems of Kashmir Himalaya have been conducted; present study in the GWLS provides a template, which can be replicated in other protected as well as unprotected areas of the Kashmir Himalaya.

Tree-rings stable isotope (δ18O and δ2H) based 368 years long term precipitation reconstruction of South Eastern Kashmir Himalaya

The hydroclimatic variability in Kashmir Himalaya is influenced by the western disturbances and the Indian Summer Monsoon. To investigate long-term hydroclimatic variability, 368 years tree-ring oxygen and hydrogen isotope ratios (δ18O and δ2H) extending from 1648 to 2015 CE were analysed. These isotopic ratios are calculated using five core samples of Himalayan silver fir (Abies pindrow) collected from the south-eastern region of Kashmir valley. The relationship between the long and short periodicity components of δ18O and δ2H suggested that physiological processes had a minimum effect on the tree-ring stable isotopes in Kashmir Himalaya. The δ18O chronology was developed based on the average of five-individual tree-ring δ18O time series covering the time span of 1648–2015 CE. The climate response analysis revealed the strongest and most significant negative correlation between tree ring δ18O and precipitation amount from the previous year's December to current year's August (D2Apre). The reconstructed D2Apre (D2Arec) explains precipitation variability from 1671 to 2015 CE and is supported by historical and other proxy-based hydroclimatic records. The reconstruction has two distinguishing features: first, it is characterized by stable wet conditions during the last phase of Little Ice Age (LIA) i.e., from 1682 to 1841 CE; and second, the southeast Kashmir Himalaya had experienced drier conditions as compared to recent and historical period with intense pluvial events since 1850. The present reconstruction shows, there have been more extreme dry events than extreme wet events since 1921. A tele-connection is observed between D2Arec and Sea Surface Temperature (SST) of the Westerly region.

Floristic composition, life history traits and phytogeographic distribution of forest vegetation in the Western Himalaya

IntroductionScientific documentation of the qualitative forest vegetation parameters of a biogeographical area provides baseline information to guide conservation strategies and design policies for biodiversity management regulations.MethodsWe present one of the most comprehensive qualitative vegetation analyses to evaluate the entire structure and function of an ecosystem in the remote northern part of the Kashmir Himalaya, India. Several multivariate ecological community analyses were conducted after determining the presence of plant species in the various habitats using a random sampling technique.ResultsIn total, 155 plant species belonging to 120 genera and 49 families occurred in the area. Asteraceae was the largest family (12% of plant species) followed by Rosaceae (11%). The patterns of species distribution across families were uneven, with 50% of the species belonging to only 7 families, and 23 families being monotypic. In terms of functional groups, the herbaceous growth form dominated. Therophytes were the dominant life form, indicating that the vegetation was disturbed. According to the phytogeographical research, 65% of the species documented in the study area were native, 15% were invasive, 14% naturalized, and 5% being casual. The majority (30%) of exotic species were reported along roadsides. Of all the species found, 39% grew in their natural habitats, such as forests, and 11% were scattered along roadsides. Plant species were grouped in five different clusters based on their floristic similarity. According to the estimated diversity indices, natural forest has the greatest values for Shannon’s and Simpson’s index. We found that the study area serves as the natural habitat for several significant, endangered medicinal plants, including Arnebia benthamii, Bergenia ciliata, Delphinium roylei, Gentiana kurroo, Phytolacca acinosa, Saussurea costus, and Trillium govanianum. Therefore, we recommend that human intervention in natural regeneration efforts be prioritized in these habitats to increase the population of these species.ConclusionExamining species features from the perspective of functional groups contributes to our understanding of the ecological aspects of the flora. It may also be useful in developing management plans to ensure long-term management of forest landscapes in this remote Himalayan region.

An annotated checklist of flora of Overa-Aru wildlife sanctuary, Kashmir Himalaya

The Overa-Aru wildlife sanctuary is one of the largest protected areas in terms of area (425 km2) in Kashmir Himalaya. Here, we present an annotated checklist of flora of the sanctuary, which includes 397 taxa (392 species, 1 subspecies, 3 varieties and 1 forma) belonging to 254 genera in 76 families. Asteraceae was the dominant family with 57 species, followed by Rosaceae and Lamiaceae with 28 and 27 species respectively. Likewise, Salix and Veronica were the dominant genera with 7 species each, followed by Artemisia with 6 species. The herbs were dominant (307 species, 77.33%) followed by trees (41, 10.33%). Lifespan wise, perennials were dominant (318 species, 80.1%), followed by annuals (66, 16.62%). The hemicryptophytes were the dominant life forms (224 species, 56.42%), followed by phanerophytes (80, 20.15%). Further, nine species occurring in sanctuary are currently recognized under different IUCN threat categories. The checklist provides the first-ever comprehensive documentation of the flora from this Kashmir Himalayan protected area, supplemented with details on natural life-history traits and up-to-date conservation status. Hopefully, the study will be immensely useful in guiding suitable conservation strategies and management planning of protected areas in the region.

Herb stratum diversity and community structure in Gurez valley of Kashmir Himalaya: application of multivariate techniques in community analyses

ABSTRACT In temperate forests, herbs comprise up to 90% of species richness yet received less attention, and their community structure, diversity patterns, and driving mechanisms still remain understudied. We provide a phytosociological overview of herb stratum to develop a vegetation model to characterize and designate vegetation groups and interpret their diversity and species distribution patterns. Multivariate analyses – classification (TWINSPAN) and ordination (indicator species analysis [ISA], non-metric multidimensional scaling [NMDS], and Canonical Correspondence Analysis [CCA]) were applied to data set collected from 32 plots across Gurez valley, Kashmir Himalaya to recognize the understory plant communities, determine the environmental predictors and highlight their significance. Altogether, 131 herbs from 38 families were recorded. TWINSPAN classified understory vegetation into three communities: Tanacetum multicule – Pedicularis pectinata – Aconitum heterophyllum (TPA), Taraxacum officinale – Trifolium repens – Plantago major (TTP), and Impatiens brachycentra – Tussilago farfara – Galium boreale (ITG). Diversity indices and species richness vary significantly, following the trend TTP>TPA>ITG. CCA revealed that disturbances, canopy, altitude, and moisture were the strongest parameters determining species differentiation. The study outlines a methodological workflow based on analytical methods and vegetation-plot data that describe vegetation groups and might be helpful in further in-depth vegetation classification syntheses and decision-making in conservation, global change issues, and management.

Assessment and interpretation of surface water quality in Jhelum River and its tributaries using multivariate statistical methods.

Water is an essential part of human life, and its pollution is a hotly debated topic on both national and international scales. Surface waterbodies in the beautiful Kashmir Himalayas are already deteriorating. In this study, fourteen physio-chemical parameters were tested in water samples taken during the spring, summer, autumn, and winter seasons from twenty-six different sampling points. The findings showed a consistent decline in the water quality of river Jhelum and its adjoining tributaries. The upstream section of the river Jhelum had the least pollution, whereas the Nallah Sindh had the poorest water quality. The water quality of Jhelum and Wular Lake was strongly impacted by the water quality of all the adjoining tributaries. To examine the link between the selected water quality indicators, descriptive statistics and a correlation matrix were used. Analysis of variance (ANOVA) and principal component analysis/factor analysis (PCA/FA) were used to identify the key variables that influenced seasonal and sectional water quality fluctuations. The ANOVA analysis revealed that there were significant differences in water quality characteristics among the twenty-six sampling locations throughout all four seasons. The PCA findings identified four principal components that accounted for 75.18% of the total variance and could be utilized to evaluate all data. The study revealed that chemical, conventional, organic, and organic pollutants were significant latent factors influencing the water quality of rivers in the region. The findings of this study could contribute to the vital management of surface water resources in Kashmir's ecology and environment.

Spatiotemporal variation of physicochemical parameters in Aripal and Watalara streams of Kashmir Himalaya using multivariate statistical techniques.

The sustainability and management of ecological services provided by the stream ecosystem requires regular assessment of its physicochemical parameters. The anthropogenic pressure in terms of deforestation, urbanization, use of fertilizers and pesticides, land use, and climate change are the major factors responsible for the deterioration of water quality. In the present study, we monitored 14 physicochemical parameters at three different sites from June 2018 to May 2020 in both the Aripal and Watalara streams of Kashmir Himalaya. The data was analyzed through one-way ANOVA, Duncan's multiple range test, two-tailed Pearson's correlation, and multivariate statistical techniques like principal component analysis (PCA) and cluster analysis (CA). A significant variation (p < 0.05) was observed in all the physicochemical parameters on both spatial (except AT, WT, and DO) and seasonal (except TP and NO3-N) scales. Pearson's correlation revealed a significantly strong positive correlation for AT, WT, EC, Alk, TDS, TP, NO3-N, and NO2-N. PCA's first four principal components were considered significant as they represented the highest cumulative percent variances of 76.49% and 74.72% in Aripal and Watalara streams, respectively. The loading and scatter plots revealed that AT, WT, TP, NO3-N, and NO2-N influence water quality. The strong loading of these parameters indicates the anthropogenic activities in the streams. CA depicted two well-defined clusters, wherein cluster-I is comprised of sites A3 and W3 which indicate poor water quality. In contrast, cluster-II is comprised of sites A1, W1, A2, and W2 which indicate good water quality. The present study could be helpful to ecologists, limnologists, policymakers, and other stakeholders in developing long-term management programs and conservation strategies for water resources.

Landslide hazard zonation using Bivariate Frequency Ratio Method along National highway-1 from Baramulla-Uri Road stretch, North Kashmir Himalayas, India

The study focuses on the application of frequency ratio method (FRM) for the creation of landslide hazard map along the National Highway-1(NH-1) road between Baramulla and Uri in North Kashmir Himalaya, India. The landslide hazard zonation (LHZ) map was prepared by integrating all the landslide-inducing factors with frequency ratio values. A database of notable landslides in the study area was integrated with the hazard map for validation. The overall study showed that 22.28% of the study area falls under very high and high hazard zones. Finally, the output map was validated using the 40% landslide validation data. Moreover, ROC curve method was utilized to validate the model which showed the acceptable result of 0.803 AUC value for the landslide hazard map of the study area. Therefore, LHZ map produced by this study can be used to guide planners or engineers in identifying safe zones for carrying out development projects and for future risk assessment studies in the study region.

Historical trends of heavy metal contamination and eutrophication in an aquatic system from Kashmir Himalaya, India

Long-term trends of heavy metal pollution in aquatic systems are significant for assessing the influence of human activities and adopting relevant management strategies. In this study, we present analyses of heavy metals (iron, manganese, copper, zinc, cobalt, nickel, and lead) in 210Pb/137Cs dated sediment cores from Ahansar lake (Kashmir Himalaya, India) covering a time span of the last 200 years. Additionally, the relative water quality analyses and compilation of historical water quality data (since 1983 CE) were performed to understand the long-term eutrophication status of Ahansar lake system. The heavy metal concentrations varied very little in pre-anthropogenic sediments (before 1980 CE) and represent geochemical background concentrations. Since the 1980s, the heavy metals (Pb, Zn and Cu) began to increase gradually corresponding to the population expansion in the region and the beginning of industrialization. Similarly, the ecological risk index (ERI) values for all heavy metals lies below 40, indicating less toxic impact of Pb, Cu, Zn and Ni. However, the increasing trend of ERI observed in Pb and Zn since 1980, indicates deterioration of the lake ecosystem. Further, the water quality parameters revealed deteriorating trend from ∼2000 CE, with an increase of total phosphorus, ammonia, nitrate and a decrease of dissolved oxygen. The present day (∼2020 CE) quantitative assessment of Ahansar lake water quality using trophic level index (TLI) reflected the eutrophic condition of the lake waters. The long-term baseline information from this study will aid policy makers and environmentalists for the development, management and restoration of water resources.
