Nepal is rich and unique in biodiversity due to diverse physiographic and climatic conditions.It ranges from 60 m to 8848 m asl. This range affect in climatic conditions and ultimately to biological diversity of its areas. Nepal is a suitable spot to study the relationship between altitudinal gradient and plant diversity. Therefore, varied climatic zones became the centre for biodiversity study and research. Researches carried out in these zones proven the ecological principles seted in different parts of the world. The above mention ecological researches are carried out by this section.
Study of plant communities and ecosystems in macro and micro scale.
