Synopsis Increasing worldwide concern over the present state of biodiversity has now given a new lease of life for exploratory studies. Neglected in the past, our knowledge about the floristic and faunistic diversity of the world as well as our country is far from complete. The impacts of human activities have led to severe changes in natural ecosystems that have resulted in extinction of many plant and animal species, and are threatening many more.

To a large extent the potential distribution of grassland ecosystems is determined by climatic variables, principally temperature and precipitation. In general, grasslands occur between forests and deserts. They are located in areas in which water availability falls below the requirement for forest at some time during the year but is sufficient to support grasses as the dominant plant type. Many grasslands have an important woody plant component.

Three factor of grassland differentiate them from other ecosystem type. This we well study in greater length in chapter. This book will be helpful for students who are pursuing graduation, post graduation, in any subject.
