“…The highest impact of ecological disturbance in these forests is found to be grazing followed by fuelwood extraction, forest fire and non‐timber forest product collection. In contrast, Neeraja et al (2022) show variable effects of harvesting on population growth in three species of trees in the dry forests in the Eastern Ghats. Aditya and Ganesh (2022) report high overlap in human and herbivorous mammal activity in the northern Eastern Ghats that needs to be taken into consideration when planning conservation programs.…”

India is a home to extraordinary climatic and geological diversity and its geographical expanse covers a wide range of ecosystems including forests, grasslands, deserts, wetlands, montane, coastal, and marine ecosystems (Rodgers & Panwar, 1988). These ecosystems are habitats for 8% of the world's biodiversity. India is one of the 17 megadiverse countries meeting the criteria of having at least 5000 endemic species and bordering marine ecosystems (MoEFCC, 2018).It is also among the top 10 countries globally in terms of their share of vascular plant, fish, amphibian, reptile, and mammal species richness (Butler, 2021). The biological wealth of India constitutes a large share of the world's flowering and non-flowering plants along with various viruses, bacteria, algae, fungi, and lichens (Singh & Dash, 2014).However, much of the biodiversity in India remains undocumented or understudied. For example, out of the estimated 800,000 species of plants, animals, and fungi, only about 190,000 have been named (Bawa, unpublished). Due to increasing population densities, the concomitant exacerbation of anthropogenic pressures such as deforestation and overharvesting, and global challenges such as climate change, India's biodiversity is currently highly threatened (Ceballos et al., 2017;Venter et al., 2015). India, in fact, is home to sections of four of the 36 regions recognized as global biodiversity hotspots-Himalaya, Indo-Burma, Sundaland, and the Western Ghats; while to be recognized as a biodiversity hotspot, a region needs to have at least 1500 endemic vascular plant species, by definition, these are also areas that have lost ≤30% of its original natural vegetation (MoEFCC, 2018). Therefore, it is timely to assess the current status of biodiversity in the country, examine factors that threaten it, and plan the way forward to overcome various challenges to conserve the unique biodiversity in India. This Special Issue of Biotropica captures a snapshot of biodiversity research in India that has implications for one or more of these aspects.

In order to manage forest ecosystems for conservation and human livelihoods, it is important to understand the effects of anthropogenic activities on plant populations of economic, cultural, and conservation concern (Grogan et al., 2014;Kaye et al., 2001). Harvesting and use of plant products, especially non-timber forest products (NTFPs), account for a large proportion of the livelihoods of people living adjacent to forests (Ticktin, 2005). Overexploitation of timber and NTFPs is a concern, as 40% of plant species in the world are at risk of extinction (Nic Lughadha et al., 2020), and unsustainable harvesting practices are major drivers of plant loss (Brummitt et al., 2015).However, traditional harvesting practices by indigenous people can often be sustainable (Shackleton et al. 2015). Further, conservation
