“…The findings are consistent with Das et al (2012), who stated that the aggregated patterns of plants indicate the preference of species for a particular habitat, while the random patterns indicate that the plant species grows in a relatively homogeneous environment. Our findings are in conformity with those of Chauhan et al (2019), who found that T. govanianum typically prefers cold, moist, and shady microhabitats, leading to patchy distribution of this species in its natural habitats.…”

“…The plant remains in one‐leaf stage for several years before its transition to three‐leaf vegetative stage; and the latter transforms into three‐leaf reproductive stage (i.e. flowering and fruiting) after the rhizome reaches a critical biomass threshold (Chauhan et al 2019). Sexually the species produces large number of seeds and asexual reproduction has been found to occur rarely, mostly in the plants with large rhizomes (Chauhan et al 2018).…”

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.

“…Notwithstanding the fact that T. govanianum is endemic to Himalayas with high medicinal value being a rich source of steroidal saponins, glycosides, tannins, flavonoids, and sterols (Rahman et al 2015;Chauhan et al 2019), it has been overharvested rampantly over time and has lost more than 50% of its populations from natural areas (Ganie et al 2019). Motivated by urgency of its conservation, our study predicted distribution of T. govanianum in current and future climate change scenarios while incorporating human pressure and land-use changes into the model.…”

Climate change, land-use changes and other anthropogenic pressures are globally the major drivers of biodiversity decline with profound implications, especially for the fragile Himalayan ecosystems. These drivers, if factored into the biodiversity conservation models, significantly improve their reliability and help a great deal prioritise habitats for better management. Here we focussed on an important medicinal plant species (Trillium govanianum), endemic to Himalayan region that is beset with the twin challenge of climate change and growing human footprint. We predicted the current and future projection of the distribution range of this species using SDM tool 'MaxEnt' supplemented with 'Zonation' software and 'human pressure index'. Decrease in the potential geographic range of T. govanianum, with a narrow room for conservation due to anthropogenic pressures in the predicted suitable habitats, was clearly revealed from our results. We identified the precise zones within the predicted suitable habitats under the future climatic scenarios (2050 and 2070) for priority conservation to endure the impact of climate change and growing human pressures. These results hold considerable promise in designing the effective conservation strategies for the target species. In the context of post 2020 biodiversity outlook, we advocate augmenting the species distribution models with human footprint index, zonation analysis and the climate change scenarios, to realistically meet the desired conservation targets.

Trillium govanianum, a medicinal herb, exhibiting diverse morphometric traits and phytochemicals across developmental stages of plants. The changes in the chemical profile and steroidal saponin levels in the rhizome of T. govanianum across different developmental stages were previously unknown. This study categorizes rhizomes into three types based on scar presence: juvenile (5–10 scars, Type I), young (11–19 scars, Type II), and mature (21–29 scars, Type III). Rhizomes show varying sizes (length 1.2–4.7 cm, girth 0.3–1.6 cm), weight (0.18–5.0 g), and extractive yields (9.7–16.1 % w w‐1), with notable differences in saponin content (5.95–21.9 mg g–1). Ultra–high performance liquid chromatography–MS/MS (UHPLC–QTOF–MS/MS)‐based chemical profiling identifies 31 phytochemicals, mainly including diverse saponins. Ultra–high performance liquid chromatography coupled with evaporative light scattering detection (UHPLC–ELSD)‐based quantitative analysis of seven key saponins reveals stage–specific accumulation patterns, with protodioscin (P) and dioscin (DS) predominant in mature rhizomes. Statistical analysis confirms significant variation (p=0.001) in saponin levels across developmental stages with chemical constituent protodioscin (P=4.03±0.03–15.76±0.14 mg g‐1, PAve=9.79±3.03 mg g‐1) and dioscin (DS=1.23±0.06–3.93±0.07 mg g‐1, DSAve=2.59±0.70 mg g‐1) with acceptable power (p=0.738; |δ|>0.5) statistics for effective sample size (n=27 samples used in the study) of T. govanianum. Principal Component Analysis (PCA) and Euclidean clustering further highlighted chemotype distinctions.
