Trees outside forests (ToF) play a vital role in reducing carbon from industrial activities and vehicles by sequestering and storing atmospheric Co₂ generated as biomass. However, there is a scarcity of studies quantifying the biomass and carbon stock in the ToFs. To bridge this gap, we conducted a study on the potential of biomass and carbon dioxide sequestration in trees planted in Puducherry. Our findings show that the total above-ground biomass of adult trees in the city was 1926.03 Megagram (Mg), while belowground biomass was 244.47 Mg. The total carbon stored in adult trees was 966.53 Mg, while the volume of sequestered CO₂ was 3547.17 Mg in the study area. To increase carbon dioxide sequestration in Puducherry town, we recommend increasing urban green cover and planting more fast-growing native species.

This study provides a detailed ecosystem valuation of Paryavaran Park in Balod, Chhattisgarh, India, assessing its economic and ecological significance. Based on the Travel Cost Method (TCM), the park’s annual economic value is estimated at Rs. 10,39,293 with 28,089 annual visitors demonstrating substantial public investment in its natural and recreational amenities. The park features diverse attractions, such as a butterfly garden and medicinal plants, which enhance its appeal. Ecologically, the study evaluates the park’s contribution to climate change mitigation through carbon sequestration. The park’s tree species collectively sequester 16,835.80 kg of carbon, translating to a monetary value of Rs. 1,25,763 based on the Social Cost of Carbon. The findings emphasize the importance of preserving and enhancing such green spaces, which play a critical role in urban sustainability. This study underscores the necessity of recognizing and monetizing the ecological services provided by urban parks, which are instrumental in combating climate change and enhancing the quality of life in urban areas. The data-driven approach reinforces the park’s multifaceted importance and supports strategies for sustainable management and conservation.

Experiments were conducted to evaluate the seed longevity period of Palmyrah. The matured fruit branches were selected based on yellow tinge in the stylar region. After manually removing the fruit exocarp and mesocarp, the uniform size seeds were shade dried for fourteen days and stored in ambient condition. The seeds were sown in raised nursery beds containing nursery mixture of red earth, sand and farmyard manure in a ratio of 2:1:1. The experiment was conducted in a randomized block design with three replications of 50 seeds each, sown at monthly intervals up to 18 months. The germination percentage was recorded at 15 days interval till the completion of germination. One year after sowing, the results revealed that fresh seed recorded highest germination of 78.67% followed by one month of stored seed (63.33%), two months of stored seed (53.33%) and nil germination was observed beyond five months of stored seed.

Calanthe lamellosa Rolfe is being reported as an addition to the flora of Manipur from Senapati district. A brief taxonomic description along with phenology and distribution of species is provided.

Miliusa indica Lesch. ex A.DC. is a tree belonging to the family Annonaceae and it grows primarily in the wet tropical biome. It is commonly known as Wooly-fruit Miliusa and locally known as Nedunaarai (Tamil). Miliusa indica is a little known species to India and Sri Lanka. In India, it’s known from Tamil Nadu, Kerala, Karnataka and West Bengal and from Eastern and Western Ghats in evergreen and deciduous forests. The present study provides detailed taxonomy notes and photographic of the species.

The negative implication on the environment and health caused by electronic waste (e-waste) is increasing and brings the need for an approach that is both creative and sustainable. The aim of this research work is to examine how artificial intelligence (AI) can be applied in waste management, recycling, and raising awareness, in order to improve the ecological outlook by reducing electronic waste’s harmful effects through further automated processes. Specific aims include exploring novel AI technologies for the e-waste sorting, predicting its mount, and optimizing the recycling processes for targeted materials. The study also tackles the issues of lack of integration of AI solutions in e-waste management, which are resource and cost limitation, and reasons for undertaking such a task to address environmental concerns. Analyze the whole research capacity to prevent isolation of e-waste management to e-waste disposal and encourage active involvement in the ongoing campaigns for environment sustainability.

A new species of Dryopteris Adans. from Dibang Valley District of Arunachal Pradesh state, N.E. India, is described. A detailed morphological description is provided along with photographs. Differences between this and allied species are pointed out. This species can be differentiated from its related species on the basis of its 2–2.5 mm wide stipe base scales extended up to 1/3^rd of the stipe, densely scaly rachis, halfway lobed pinnae with rounded-truncate, irregularly dentate lobe apices.

Dinetus malabaricus (C.B.Clarke) Staples (Convolvulaceae), an Indian endemic species known only from Maharashtra, Karnataka and Tamil Nadu, is reported for the first time from Nauni, Solan district, Himachal Pradesh, as a new distributional record to Himalaya.
