An observational technique has been followed in the research and in this regard, the pellet count of the herbivores has been selected as subjects for observation. Due to the digestion characteristics of herbivores, the pellet count has been considered as the subjects by whom the differentiation of the herbivores can be possible. A four-year time bound has been set for the collection of samples to interpret in the analytical approach followed in the research. Understanding the changes in the richness of herbivores has been considered as one of the main focal point regarding the collection of data for completing the research in a significant course of action.
