Jalthal Forest (62.6 km2) is a remnant forest patch of a once continuous, lush and dense area of sal Shorea robusta and mixed deciduous vegetation in eastern lowland Nepal that is now surrounded by a dense human population. The forest is one of the last remnants of suitable habitat for the Critically Endangered yellow-headed tortoise Indotestudo elongata. This study explored the distribution of and conservation threats facing the yellow-headed tortoise in Jalthal Forest through field surveys in 20 community forests and structured interviews with 80 members of 22 community forest user groups and local people during September–November 2021. We surveyed 11.3 km2 of the forest and observed only four individuals of I. elongata, indicating a population density of 0.35/km2. Local people perceived that the species is decreasing mainly because of hunting (42%) and habitat deterioration from incursion of invasive species (30%). Based on the interviews with local people involved in hunting, an annual mean of 6.8 tortoises were killed during 2017–2021. The purposes of hunting were consumption (70%) and ethnomedicinal uses (30%) by the Meche and Sathar communities. Awareness campaigns and networks of communication amongst all stakeholders are required to conserve this species in Jalthal Forest.

Bryophytes (including mosses, liverworts and hornworts) are a heterogeneous group of terrestrial plants, which comprise over 24,000 species worldwide. Given the various biological activities reported from bryophytes, they have a huge commercial potential. Due to their minute size and rather small biomass in various ecosystems, bryophytes are a seldom part of ethnomedicine and rarely subject to medicinal and chemical analyses. Still, hundreds of novel natural products have been isolated from bryophytes. Bryophytes have been shown to contain numerous potentially useful natural products, including polysaccharides, lipids, rare amino acids, terpenoids, phenylpropanoids, quinones and many other specialized metabolites. Additionally, different bryophyte extracts and isolated compounds have shown antimicrobial, antiviral, cytotoxic, nematocidal, insecticidal, effects on smooth and non-striated muscles, weight loss, plant growth regulators and allelopathic activities. Bryophytes also cause allergies and contact dermatitis. All these effects highlight bryophytes as potential source for herbal remedies and production of chemicals to be used in various products.
