In many areas crop and livestock producers could supply significant biodiversity conservation services by avoiding conversion of lands to agricultural use or by facilitating conservation in agricultural areas.
Agriculture can contribute to wild biodiversity by maintaining areas with relatively undisturbed ecosystems, minimizing the use of land and water resources that are rich in species, and reducing agricultural practices in areas that have been identified as important for wild biodiversity conservation (these areas can then be incorporated into national parks and reserves).
