Small mammals play a vital role in the ecosystem. They have significant influences on vegetation, soil, exert predatory pressure on other animals, provide food for predators, and influence other components and ultimately the whole system. Vegetation influences may include effects on primary productivity as small mammals can consume about 60% to 80% of plant species composition, and decomposition of plant materials. They influence the rate of decomposition of organic materials by adding as much as 58% of green herbage and reducing the particle size of vegetative material. Reduction of particle size of living and dead vegetative by small mammals also increases decomposition rates. Their primary food consists mainly of grasses, herbs, leaves,
