“…, to identify the most probable distribution of the species. Over the years, Maxent software has emerged as one of the most promising and authentic tools to study the habitat suitability of various categories of tree species globally including dry deciduous species (Chitale and Behera 2012 ; Deb et al 2017 ; Kumar et al 2020 ; Torlap and Lamthai 2019 ). Therefore, the present study was persuaded with the objective to identify the most suitable habitat of B. monosperma for chalking out strategies for its conservation and promotion of lac cultivation and socio-economic amelioration.…”

The present paper highlights the importance of lac cultivation through Butea monosperma . We have modelled the suitable habitat of major lac host B. monosperma using MAXENT for the current and future climatic scenarios (RCPs 2.6, 4.5, 6.0 and 8.5). The study suggested the dominance of suitable habitats of B. monosperma in central-eastern to eastern and southern parts of the country. Temperature seasonality (Bio_4) was the most significant bioclimatic variable in regulating the distribution of B. monosperma followed by elevation and annual precipitation (Bio_13). The projection for the year 2050 suggested the habitat shift towards the eastern and southern parts. The study indicated the major habitat of B. monosperma continued to exist in the Chotanagpur plateau in eastern India. The model predicted approximately a 9–13% decrease in the overall potential habitat of B. monosperma by 2050, and the distribution of species would be nearly extinct from the northern and western parts. Presently, only the 5% lac host trees are being utilised for lac cultivation, and the study suggested that conservation and promotion of B. monosperma on projected suitable habitats and even by utilising 25% of resources, the lac production may jump manifold catering to global demand, rural economy and employment and shall contribute towards ‘Self Reliant India’.

“…This creates competition and the alteration of the ecosystem balance, resulting in a poor population in disturbed sites. Kumar et al [74] observed the skewed population structure of P. marsupium in the central and eastern zone of India due to poor natural regeneration, which was a result of anthropogenic factors and the vigorous growth of associated species. Regional-scale climate change in tandem with deforestation and habitat unsuitably are also responsible for the declined population of P. marsupium from it natural geographical ranges in India [75].…”

Plant biodiversity data are prerequisites for the sustainable management of a forest. We used quantitative ecological tools to determine the species composition, diversity (richness and evenness), population structure, distribution patterns, and regeneration status of trees in a Tropical Moist Sal Forest of Eastern Ghats, India. For this purpose, a field inventory was conducted during 2020–2022 in sixteen 1.0 ha forest stands along a human-induced disturbance gradient. A total of 161 species (61 trees, 40 shrubs, 60 herbs) belonging to 77 families and 143 genera were recorded in the 16.0 ha of forest area. The results revealed a significant (p < 0.01) decrease in the tree and shrub species density, basal area, species richness, and diversity along the gradient of disturbance. However, in the case of herbs, the Shannon–Weiner diversity index increased significantly (p < 0.01) with increasing disturbance levels. Irrespective of forest types and disturbance levels, the tree diameter class (10–30 cm) accounted for the highest stem density in the forest. A mixed trend was found in the case of the basal area; the >41 cm diameter class constituted the highest basal area in the Pure Sal Forest while the 10–30 cm class was in the Moist Deciduous Forest without Sal. Tree species richness was found higher in lower diameter classes. Disturbances impacted the distribution pattern of trees; in the Pure Sal Forest, the contagious distribution of trees were 61.54%, 40%, and 12.5% in undisturbed, low-disturbed, and moderately disturbed sites, respectively. The percent of trees showing random and regular distribution increased with the increased level of disturbance in all forest types. The number of tree species having good regeneration decreased with the increased disturbance intensity in all forest types. Frequent grazing, repeated forest fires, and poor soil seed banks at the Moderately Disturbed site were the main reasons for the poor/no regeneration of Pterocarpus marsupium, Adina cordifolia, Terminalia bellerica, and some other economical species. Significant changes in structural attributes of the tree community revealed the impact of human-induced disturbances in the Moist Sal Forests of Eastern Ghats. The disturbance mosaics promoted the growth of many invasive weed species and lianas, depleting the number of valuable species in the forest. This study suggests the adaption of sustainable biodiversity conservation approaches through the active participation of the tribal so that the remnants the Moist Sal Forests of Eastern Ghats can be controlled to prevent further degradation.

“…It is also beneficial for treating jaundice, fever, wounds, diabetes, stomach aches, and ulcers [4]. Nonetheless, anthropogenic overexploitation of genetic resources, along with poor natural regeneration, survival, and growth rates, has elevated the probability of species extinction [5]. A number of species from the same genus have already been red-flagged by the concerned authorities.…”

Aims: Pterocarpus marsupium Roxb. is an important timber species with high medicinal properties belonging to the Fabaceae family. The species is severely threatened by anthropogenic and ecological pressures coupled with less natural regeneration. No results in vegetative propagation methods and very less germination is reported for the species under nursery conditions. This study investigates the germination potential of P. marsupium seeds under the prevailing climatic conditions of regions in eastern India. Place and Duration of Study: The study was carried out at the ICFRE - Institute of Forest Productivity (IFP), Lalgutwa, Ranchi, during the 24th to the 32nd Meteorological Standard Week (MSW) of 2022, spanning from June to August. Methodology: Seeds were collected from three CPTs selected from natural forests of Jharkhand, Bihar and West Bengal and the experiment was carried out following split plot design. Observations on several germination parameters and seed vigour indices were recorded until eight weeks after sowing and subjected to factor multivariate analysis of variance (MANOVA) in SPSS 25.0. Results: The experiment revealed that alternate wetting and drying of seeds significantly (P <. 001) outperformed all other treatments with a highest germination percentage of 60±1.196%. Accessions from Jharkhand and West Bengal exhibited significantly (P < .001) better vigour indices (1959.8, 1855.35 for SVI-I and 538.715, 527.742 for SVI-II, respectively) compared to the accession from Bihar (1796.49 and 532.618 for SVI-I and SVI-II). Although the study did not find any significant interaction between the treatments and accession, there was a statistically significant impact on the aggregate dependent variables (F (126,503.279) = 1.579, P <. 001; Wilks' Λ = .077). Conclusion: The results of this study report an economically feasible and rapid seed treatment method for establishing field gene banks of P. marsupium in eastern India to aid its ex-situ conservation practices.
