Animal Research Program


Under Animal Research Program, the Animal Research Laboratory (ARL) has been established. The ARL is a part of Faculty of Science established in 2073/074 (2016AD) by the scientists, administrators, planners, and academicians of Nepal Academy of Science and Technology. 

To conduct various research and promotional activities related to the prioritised topics of the country in the context of the welfare of the animals and humans. 

The objectives of ARL are:
•    Immunoparasitology
•    Pharmaceutical sciences  
•    Ethnomedicine and Conservation biology

Current Activities
•    Investigating the endoparasites of animals.
•    Assessment of the ectoparasitic species in animals and their roles in disease transmission.

Darwin Initiative Project

Partner organizations: RBGE (UK), NAST (Nepal), DPR, MoFE( Nepal), CDB, TU (Nepal), HELVITAS (Nepal), Forest Action(Nepal) AEPC (Nepal).

Science-based intervention reversing negative impacts of invasive plants in Nepal: Invasive Alien Species are one of the major threats to biodiversity and ecosystem health, and considerable burden in agriculture and forestry. The project aims in: developing the scientific knowledge-base and in-country capacity to tackle increasing challenges from invasive plants in Nepal; engaging local communities in recognition, control and utilization of invasive plants, and restoring infested lands; using invasive plant biomass for alternative, carbon-sensitive bio-energy sources to improve livelihoods, reduce poverty, conserve biodiversity and offset carbon. Project activities focus on Bardiya, Nawalparasi and Makawanpur districts of Nepal.

Flora of Nepal Publication

Partner organizations: RBGE, Natural History Museum, London (UK), NAST (Nepal), University of Tokyo (Japan), DPR, MoFE (Nepal), CDB, TU (Nepal)

The purpose of the Flora of Nepal project is to produce the comprehensive account of all the estimated 7000 species of vascular plants of Nepal. One of the outputs is a series of ten printed volumes, written in English. The main use for the printed Flora is plant identification. The Flora of Nepal sets out to produce a new approach to specimen-based Flora writing. There are guidelines ( which help to prepare taxonomic treatments that are as consistent as possible both within and between volumes of the Flora. Subsequent versions of the Guidelines and supporting documents will be available in the Flora of Nepal website (

Microbial Culture Collection Centre

Nepal is rich in biodiversity and microbial resources due to its unique topography and high variability in eco-climatic conditions.Microorganisms have been recognized as vital components of the world’s biodiversity.  Microorganisms are essential for life since they perform numerous functions like nutrient cycling, environment detoxification, production of antibiotics, vitamins and industrial enzymes etc. Despite the importance of microbial resources, priority has not been given for the preservation of these resources.  Most of the strains are lost due to lack of adequate permanent and reliable repository. Long-term preservation of micro-organisms is an often neglected but very important aspect of both applied and environmental microbiology. Realizing the importance of preservation of this microbial resource, Nepal Academy of Science and Technology (NAST) aims to establish a Microbial Culture Collection Centre (MCCC) at NAST. Preliminary work on establishment of MCCC has been initiated. Thiscenter will play a crucial role in preservation and sustainable use of microcroorganisms.

Model Scientific Village

Model Scientific Village (MSV) is a village/area which comprises all the existing theoretical and practical knowledge of science (Biology, chemistry, physics, geography, environmental sciences, engineering, and others) and the local people think, read, follow, regulate, and sustain science and scientific facts. The concept of MSV is significant for all people with different professions and characteristic groups, for example, for generalists and specialists, for young and adults, and for male and female. The objectives are: to develop the village based on sustainable development; to conduct the income-generating programs and trainings on health awareness, environment, and science, and to identify and establish basic and advanced technology.

Currently Model Scientific Village program is running at Musahari Tole, Haribhawan, Lalbandi-4, Sarlahi.

Yarsagumba Research & Development

Yarsagumba (Ophiocordyceps sinensis; syn. Cordyceps sinensis) is the most expensive bioresource available in world today. So far, Nepal is the second largest supplier of this mushroom, with official annual production standing around three tonnes. Excessive harvesting to meet the increasing demand in the international market is threatening the livelihood and the existence of this species in its native habitat. For last few years’ serious concerns on the availability and abundance, appropriate policy on collection, processing, and trade of the resource have been raised by collectors, traders, researchers, conservationists, and policy makers within the country. On the other hand detailed analyses of the ecology, life history, population dynamics, habitat condition, awareness among harvesters, and assessment of natural stocks for sustainable use of this valuable resource are lacking. With these backdrops this program has envisaged to relieve our alpine meadow (grasslands) from all those environmental or other types of stresses and make the resource sustainable as its primary goal.
