Subject: Volume and Biomass Tables for Farm-grown Malabar Neem(Melia composita Benth.) for Central Plains of Punjab
Keywords: Melia composita, Volume table, Biomass table, Height, DBH, Punjab
Abstract: The present study was carried out in the central plain region of Punjab state. The data on tree height and diameter at breast height were recorded on Melia composita trees belongs to different girth classes and having tree height and DBH ranging from 9.30 m to 19.90 m, and 6.37 to 35.67 cm, respectively. The trees were felled and cut into logs of acceptable merchantable lengths. The data on log length, log diameter on both ends and at mid-point, and log weight were recorded. The volume regression equations were developed to predict the volume table on basis of DBH and tree height (combined variable model), and DBH alone (single-entry model).Results were statistically analyzed and found that all equations had very good-fit. Timber volume and biomass predicted by single-entry model (R2+0.948) were found quite near to the actual volume and biomass estimated by manual harvesting of the trees but at lower girth class trees. However, combined variable model (R2=0.886) was found best fit for the trees belong to upper girth classes for Melia composita plantation. Besides, timber biomass table was developed to get the rough estimation of tree standing biomass so that the farmers can sale their trees at an appropriate price. These tables will be useful to the farmers, timber growers, wood contractors, state forest departments, research workers and the planners for future plantation programmes.

Keywords: Anand van, Enrichmnet plantation, Indian Himalayan region, Nanda van, Trees outside forests, Sustainable urban forest management
Abstract: Trees Outside Forests (TOF) and Enrichment Plantations (EP) are strategies used in urban forestry management to increase green cover and address various ecological issues such as deforestation. The Government of India has initiated the promotion of TOF and EP to address resource demands and provide various ecosystem services in urban and semi-urban areas. This study examined Anand Van (an urban TOF) in Dehradun and Nanda Van (an EP) in Almora, focusing on their ecological attributes that reflect the suitability of the two forest management systems to address environmental challenges. Phytosociological analysis revealed that broad leaved Mallotus phillippinensis was the dominant species in Anand Van; whereas needle leaved Pinus roxburghii was the dominant species in Nanda Van. The importance value index (IVI) indicates higher ecological significance for TOF due to their more diverse missed vegetation and natural regeneration, resulting in higher biodiversity compared to EP. Recognizing the complementarity of these strategies and spreading awareness among stakeholders is essential for sustainable urban forest management .A location-specific mixed-method approach of both strategies can help improve urban greenery and ecosystem services and augment business strategy through natural resource management.

Keywords: Agroforestry, Biomass, Carbon sequestration, Soil carbon and Climate change
Abstract: Agroforestry plays an important role in global carbon cycle and regulating the earth's climate. The present study was conducted with the objective to know about the carbon sequestration potential of different agroforestry practices in Periyapatana and Hunsur tehsils of Mysore district, Karnataka. Based on the reconnaissance survey four prominent practices viz., multipurpose tree (MPT's) on farmlands, block plantations, boundary plantations and control (i.e. agricultural crop without (trees) were selected for the present study. Among the four practices, highest biomass, biomass carbon, soil organic carbon stock, total carbon was recorded in block plantations whereas lowest was recorded in control, Total biomass and biomass carbon varied from 3.92 Mg ha-1 to 63.39 Mg ha-1, 1.84 Mg ha-1 to 29.79 Mg ha-1, respectively. The SOC stock ranged from 13.14 to 22.05 Mg ha-1.Total carbon stock across the different practices ranged from 14.98 Mg ha-1 to 51.84 Mg ha-1.Thus, the study highlights the need for policies that promote agroforestry adoption through incentives, technical assistance and integration into national carbon offset programs, thereby reinforcing its potential as a nature-based solution for environmental sustainability and rural livelihoods.

Abstract: Ecological studies assess the biodiversity status of vegetation. Knowledge of ecological composition, tree species variety, and dominating ecosystem communities serves as a framework for biodiversity conservation management planning and implementation. This study focuses on characterizing the diversity and phytosociological attributes of tree species in surrounding the Ratanpur Forest areas of the Dungarpur division of the Rajasthan state. The research employs a total of 15 stratified random sampling plots laid, and a total of 30 tree species belonging to 22 genera and 27 families have been recorded. The study revealed that the total density of tree species was 1090.13 individuals/ha. In the whole Ratanpur Forest area. The estimated carbon sequestration of these tree species has been calculated using a non-destructive method. Among these 30 tree species, 90.31 tonnes of carbon were stored, with the maximum carbon storage found in Tectona grandis (Sag) (21.78 tonnes of carbon). This detailed understanding of the phytosociological characteristics of the tree species will enable better forest management, conservation efforts, and sustainable utilization of forest resources.

Abstract: Plantation of dwarf species (preferably medicinal plants) in right of way (RoW) of transmission lines is a unique mandatory condition in the projects of forest land diversition for transmission lines under Forest (Conservation) Act.1980; now named as Van (Sankarshan Evam Samvardhan) Adhiniyam, 1980.It provides a unique opportunity of vertical dual land use by differentiating the vertical space above land for different uses. In part-1 and II of the present study, various aspects of the existing practices including safety, species selection, spacing of seedlings, phytoclimatic zones and vegetation types were given based on review of 1080 projects of forest land diversion for transmission lines. Cross-sectional analysis of RoW of transmission lines of different voltage levels was made to find out the available vertical space. The method of calculation of horizontal space (k-value) for relatively tailer (T-value) dwarf plants was also given along with differential height model of plantation. A list of 250 perennial dwarf species of different phytoclimatic zones of India was given along with their distribution, local names, available propagation techniques and palatability/edibility for wildlife. The detailed plan of plantation of dwarf species including lay-out, cost analysis, rate of levy demand and method to calculate levy for future years was also given in part-III of this study, the comparison of various guidelines of MoEF &CC and CEA issued in 2023 is made with those of earlier guidelines/regulations to update the outcomes of study. Views on further amendment of guidelines/regulations to reconsideration of available vertical space for dwarf plants were given to utilize the unused vertical space at safe distance (vertical clearance) in place of distance from maximum sag point.

Keywords: Urbanization , Urban green spaces,People perception, Ecosystem services, Willingness to Pay
Abstract: This study examines three urban green spaces in Gururgram: Tau Devital Park, Maharana Pratap Swaran Jayanti Park and Tau Devital Biodiversity Botanical Garden. The study explored the motive and purpose of the visit, user's understanding about ecosystem services given by these spaces, willingness to pay monetary value for the ecosystem services, park upkeep, and management issues which they want the authorities to take cognizance. The results show a higher number of male visitors and young working visitors. The factors that influence park preference are large walking spaces, accessibility and biodiversity. People prefer visiting in groups for health benefits and enjoy pen green spaces. Grass was the most preferred vegetation.66% of respondents acknowledged the provisioning and regulating services provided by urban green spaces. Only 50% were willing to pay for the ecosystem benefits while 37.67% strongly disagreed with the idea. Those who supported the idea supported levying a modest fee for better maintenance and up-keep of the park. Issues faced by visitors involve poor lighting, dog-menace, safety concerns, poorly maintained or lack of basic amenities and presence of anti-social elements. Findings of the study will help authorities to align their efforts towards improving user's experience.

Keywords: Carbon sequestration, Melia dubia, soil nutrient status
Abstract: The field experiment to standardise spacing for block plantation of Melia dubia was initiated during July 2010 at ‘M’ Block, Agroforestry unit, Zonal Agricultural Research Station, University of Agriculture Sciences, Gandhi Krishi Vigyana Kendra, Bengaluru. The experiment was conducted in alfisols having moderate water holding capacity (10% to 18% at field capacity), with acidic soil pH (5.5), low organic carbon content (0.30%), low in available nitrogen (235 kg ha–1), medium in available phosphorus (32 kg ha–1) and medium in available potash (299 kg ha–1). The experiment consisted of six spacing, viz. S1 (24 m × 5 m), S2 (20 m × 5 m), S3 (16 m × 5 m), S4 (12 m × 5 m), S5 (10 m × 5 m) and S6 (8 m × 5 m) which accommodated 83, 100, 125, 166, 200 and 250 trees per hectare, respectively. These were laid out in strip plot design and replicated four times. After ten years of planting, the results revealed that there was wide variation in tree height, girth at breast height (GBH) and canopy spread with different spacings. The tree height was significantly higher in S1 (14.02 m), followed by S2 (13.99 m) and S3 (13.04 m). A similar trend was observed for GBH (125.39, 117.03 and 105.36 cm, respectively), canopy spread N–S (8.89, 8.61 and 8.27 m, respectively) and E–W direction (8.35, 8.17 and 7.86 m, respectively). Variation in tree biomass accumulation was also found. The maximum total biomass was recorded with the spacing of S4 (91.74 tonne ha–1), followed by S6 (81.44 tonne ha–1) and S5 (79.85 tonne ha–1). The higher above-ground biomass of M. dubia in S1 is due to wider canopy spread and vigorous growth. Similarly, higher tree carbon was sequestered with the spacing of S4 (157.81 tonne ha–1), followed by S6 (140.10 tonne ha–1). The least carbon was sequestered with S3 (124.94 tonne ha–1). Apart from it also enhanced nutrient content in the soil, viz. soil organic carbon (0.69%), Available nitrogen (295.0 kg ha–1), Phosphorus (29.72 kg ha–1) and potassium (298.0 kg ha–1). There is an improvement in soil pH (6.65) compared to the initial status. Finally, it can be concluded that M. dubia planting at a wider spacing of 24 m × 5 m will be effective with respect to tree height, GBH and canopy spread after ten years of planting. But the spacing of 12 m × 5 m helped in enhancing the soil health and sequestering 157 tonnes of carbon per hectare.

Subject: How do urban trees vary across India? a comparative analysis across ten Indian cities
Keywords: City trees, flowering season, fruiting season, Sorenson’s index, urban tree pollinators.
Abstract: The present study was conducted to examine the variation in dominant tree species richness, composition, green cover per capita, tree-species traits, and ecosystem services to understand the similarity in urban tree distribution across 10 Indian cities. We compiled a list of 226 dominant tree species across all 10 cities. The cities showed a maximum similarity in urban tree flora of 56% (Sorenson’s index), the lowest being 19%. All cities displayed the dominance of faster-growing species. We emphasise that a good mix of native vs exotic and diversity of traits would make the urban landscapes more resilient and resistant under unpredictable climatic conditions.

Subject: Understanding chlorophyll dynamics in aquatic ecosystems in Bay of Bengal
Keywords: Chlorophyll dynamics, dynamical system, fixed point.
Abstract: The present article explores the dynamics of chlorophyll concentration in aquatic ecosystems of the Bay of Bengal, emphasising its critical role in supporting phytoplankton populations and, consequently, the health of marine environments. The study presents a chlorophyll dynamics model governed by a differential equation that incorporates intrinsic growth rates, carrying capacity and loss processes. A significant finding is the identification of a stable fixed point at C = 1 mg/m3 , which represents a threshold concentration for chlorophyll. At this concentration, the system is poised for maximum fish catch, as it indicates optimal conditions for zooplankton grazing, which in turn supports higher trophic levels. Understanding this relationship is also vital for effective ecosystem management and predicting algal blooms, thereby contributing to sustainable fisheries and aquaculture practices. The implications of these findings underscore the importance of monitoring chlorophyll dynamics to maintain ecological balance and optimise fishery yields.

Subject: Alterations in 3D vectorcardiographic loop length in acute myocardial infarction patients: a quantitative study
Keywords: Myocardial infarction, QRS loop length, sling length, spatial distance, vectorcardiogram.
Abstract: Cardiovascular diseases, especially acute myocardial infarction (AMI), are major global health concerns. The present study focuses on the QRS loop of the three-dimensional vectorcardiogram (VCG), a key indicator of ventricular electrical activities. By comparing healthy individuals and AMI patients, we found a notable decrease in QRS loop length among those with AMI measured using Euclidean point-to-point distances. This shortening suggests a clustering of vectors due to myocardial necrosis and disrupted electrical conduction. The findings emphasise the diagnostic value of QRS-based VCG analysis, offering insights into cardiac electrophysiology and highlighting its promise for early detection and predicting the prognosis of myocardial infarction.
