The survey was conducted over a period of 12 months from September 2023 to August 2024, dealing with species of birds, seasonal population dynamics, and habitat associations across this ecologically important region. Observations were conducted at peak bird activity hours on grasslands, forests, agricultural land, and water bodies with the observations recorded systematically. A total of 117 species of birds were recorded comprising 16 orders and 51 families,

Birds are natural sentinels, sensitive and significant environmental bioindicators. Bird research in every location allows us to gain a better grasp of the ecosystem's general health and to demonstrate the importance of any landscape or sanctuary for avifaunal conservation. The study was carried out at the six ranges of Kaimur wildlife sanctuary (KWLS), Bihar, India, from January to March 2021 to investigate the diversity and status of avifauna. The line transect method was used to cover the majority of the research region. There were 178 bird species recorded, divided into 19 orders and 61 families. The Bhabhua range has the maximum bird diversity, with 163 species, while the Adhaura has the least, with only 127 species. With 30 families and 79 species, Passeriformes was the most prominent order. This study also looked at the habitat occupancy and relative diversity index (RDi) of the local avifauna. According to habitat distribution, 69 percent of the species are terrestrially dependent, with aquatic (25 percent) and waders (6 percent) species respectively. The rdi of 5.6 was found highest in the families Anatidae and Accipitridae. As a result, KWLS offers a potential home for sound avifauna with a diverse population. To improve the status of resident and migratory birds, the area requires appropriate management and conservation initiatives as part of ecotourism.

Natural vegetation of these lands was very poor and sparse in distribution and diversity. It is due to natural factors as well as made factors like high intensity biotic interferences (grazing pressure) in form of illicit felling and collection fuel and fodder. Despite of this, very little information's available about existence of medicinal plants on the typical ravine flora. The present study objective is to explore and elucidate the diversity and distribution of persistent native plants and their ethno medicinal uses in rehabilitated Chambal ravines (Rajasthan). In this study, 106 species observed and it represents 54 families of plant kingdom. The maximum revival of native plant species observed in rehabilitated ravines than open natural jungles. The documented indigenous plant species are having special stress tolerance capacity and ability to establish through root suckers to adopt this harsh and fragile environment. Through active and passive rehabilitation measures coupled with appropriate soil conservation techniques might foster the reappearance/revival of native medicinal species in rehabilitated ravine region. Now, special and proper attention towards documentation, conservation, sustainable utilization and awareness creation are highly needed to protect indigenous medicinal flora by appropriate active and passive restoration measures in fragile ecosystems.

They exhibit a wide range of characteristics, behaviors, and adaptations, making them a subject of significant scientific interest (Jones KE and Safi K, 2011). The global mammalian fauna is represented by 6,495 species, of which 6,399 are extant and 96 are extinct (Mammal Diversity Database, 2019). India has a total of 423 species, which accounts for 7.81% of the global mammalian species (Sharma et al. 2015).

The central mining area covers an area of 39.50 km 2 , while the surrounding 2 km and 10 km buffer area including mining area covers 107.06 km 2 and 622.88 km 2 , respectively. Five different land use classes i.e. agriculture land, forest cover, mining area, barren land, built-up area, and water bodies in the mining area and adjacent area were analysed for six/ years, i.e., from 2016 to 2022. The changes were detected on a three-year intervals using IRS satellite LISS-IV images. This research depicts the present LULC scenario and the impact of mining on the landscape. In the mining area, there is a drastic reduction in agricultural land (41.26%) and forest land (28.23%). The waste land area recorded sharp increase in mining area (857.13%) and its 2 km surrounding area (138.84%) and 10 km buffer area (119.17%). The increase in built up area recorded for 2 km buffer area was 106.79%, whereas 61.06% for 10 km buffer area. It is expected to reduce the burden on policymakers to prepare an efficient mines development plan and meet sustainable development goal (SDG) 15 (Life on land). The paper highlights the importance of digital change detection techniques for nature and location of the change of the mining area.

It is the lifeline of Chhattisgarh and Odisha. The Mahanadi River Basin (MRB) in Chhattisgarh covers an area of 75,136 km2.This paper provides a detailed database on water demand and use, LULC changes, biodiversity, pollution status, and man-made structures, such as dams/ reservoirs, built in the Mahanadi river basin in Chhattisgarh. The significance of this overview paper stems from the fact that it improves river management and water distribution for various sectors in Chhattisgarh. Furthermore, it aids in the mitigation and adaptation to climate change, as well as the achievement of sustainable development goals.

Teak is a major tree species with 32 other forest tree species in the plantation site. The study of ground leaf litter production in respect to rainfall variation from 2005-2011 shows that the average (±se; n=20) annual leaf litter production varied between 881 and 1370 g dry mass m-2 year-1. The 70-90% litter was produced in the dry seasons and 55-70% in wet seasons. On annual basis mean (±se; n=20) the highest total litter fall production varied 7.67±0.31Mg/ha/year in 2009 and lowest 6.00±0.33 Mg/ha/year in 2011. The plantation floor litter mass found highest 6.54±0.31 Mg/ha in year 2006 and 5.03±0.25 Mg/ha in year 2010. The decomposition of litters found highest in annual rates 13.87±1.06 Mg/ha/year in 2005 and 11.08±0.84 Mg/ha/year in 2010.
