Biotic resources, or the animals, plants, fungi and microorganisms, derived from a unit of land – measured in richness and abundance. Society, and an agricultural operation, benefit from biodiversity in terms of pollination of crops, predation of pests, hunting and enjoyment of nature. Biodiversity can be impacted directly by management practices such as seeding divese species into a pasture or cover crops as well as indirectly through grazing management or the type of tillage system employed.
