Prunus species play an important role in preserving the Nepal's unique identity; such as three endemic species of Prunus, Prunus topkegolensis, Prunus jajarkotensis, and Prunus taplejungnica, represent the country's local area. An ecological and social survey of P. topkegolensis and P. taplejungnica was conducted. To analyze these species' regenera...

Tree regeneration is one of the determinant factors for forest sustainability. We assessed the regeneration status of tree species in the four selected community forests of subtropical hills in Lamjung District, central Nepal. We laid 30 square plots (400 m2, 50 m2, and 4 m2) to collect vegetation data and recorded 23 tree species, with seedlings 5...

Prunus mira and Prunus armeniaca are the two prominent fruit-bearing plant species in the Nepal Himalaya and possess notable ethnobotanical significance.

The effect of invasive species on biodiversity is a major issue of world. This study was conducted at the Shivapuri Nagarjun National Park, this study assessed the invasive species status factor associated with it and their impact on seedling and sapling of trees. Modified Whittaker Nested sampling stratifies was adopted for vegetation sampling....

To date, little is known about the evolution of fern genomes, with only two small genomes published from the heterosporous Salviniales. Here we assembled the genome of Alsophila spinulosa, known as the flying spider-monkey tree fern, onto 69 pseudochromosomes. The remarkable preservation of synteny, despite resulting from an ancient whole-genome du...

The current Nepal Science & Technology Report contains six chapters. The first chapter provides a general background with an outline of Nepal’s natural resources and historical account including its indigenous technologies. In 2015, Nepal promulgated a new constitution after embracing a federal setup. The Constitution has included fundamental righ...

Melogale personata I. Geoffroy Saint-Hilaire, 1831, Large-toothed Ferret Badger (Mustelidae), is distributed from Nepal to Vietnam with very few records. It historically is known by only one recent sighting record from an unspeci-fied area of Nepal. The IUCN species distribution map shows this species in the Okhaldhunga District. We confirm the pre...

The community forest program in Nepal is one of the successful conservation initiatives. Tree species in a forest ecosystem have a fundamental role in maintaining the vegetation structure, complexity, and heterogeneity. This study analyzes the composition and regeneration of tree species in five community forests (CFs) of the sub-tropical region, L...

Carbon stock related studies in the forest are gaining attention these days as it is essential for climate regulation. We conducted a study in the Aadarsha Namuna community forest, Buddhashanti Rural Municipality, Jhapa, to estimate the carbon stock in this forest. For this purpose, we recorded data from a total of 35 circular plots (each of 250 m2...

Urban forest patches are under increased pressure from invasion by alien species and are strongly affected by anthropogenic activities The vegetation present in the matrix of urban sites is a rich source of alien invasive species. The patch experiment involved initiating invasion in different habitat types (roadside, disturbed, open boundary & dens...

Urbanization and linear infrastructure are reported to influence amphibian assemblages and populations. In areas undergoing rapid infrastructure development and urbanization, the mounting threats to biodiversity are evident. Although protected area coverage and focus on charismatic species conservation are well recognized, non-charismatic species s...
