Faunal biodiversity is facing several threats of natural and human origin. These threats have brought widespread changes in species, ecosystem process, landscapes, and adversely affecting human health, agriculture and food security and energy security. These exists large knowledge base on fauna of Nepal. Initially, foreign scientist and researchers began explored faunal biodiversity of Nepal and thus significantly contributed knowledge base. But over the decades, many Nepali scientists and students have heavily researched on the faunal resources of Nepal. Collaboration and interaction between foreign researchers and Nepali researchers and students are important step for further research and conservation of Nepali fauna. Under above scenario Central Department of Zoology, TU has organized a National Conference on 28–30 November 2020 to provide a common platform for the students, academicians, scientists and researchers from different organizations to share their knowledge and experiences so as to generate sufficient interest for further research in the area of faunal resources. It is believed that the conference helped in motivating young researchers working in different aspects of biological sciences. The conference represents a significant mega event in the history of Zoological Community of Nepal. A large number of delegates from different premier academic, research and management institutions in the country and abroad have participated and shared their research findings at the conference. In all five keynote lectures, 20 invited speeches and 126 contributed papers were presented at the conference. Besides, there were three panel discussions on various issues of fauna of Nepal. Important part, post conference event was collection, review and edit of papers, and ultimately publication of the proceedings.

Other good paper authors/presenters from the NCZ 2020 are asked to extend their papers for possible inclusion in the forthcoming issues of Nepalese Journal of Zoology- a peer reviewed journal published by the Central Department of Zoology, Tribhuvan University. The proceeding contains many interesting research articles from various sub-disciplines of biological sciences. The proceedings will widen knowledge base and understanding about faunal biodiversity of Nepal. We would like to thank all the contributing authors for sharing their valuable research papers through this proceeding. Thanks to the editors who agreed to help us by managing manuscripts. They performed incredible job in reading, reviewing, editing and making final decisions on whether those documents should eventually become part of the proceedings.
