mammals

Nearly everyone enjoys the occasional sighting of a deer near home. Increasingly, though, deer herds are growing so large that the animals over-browse their habitats, decimate gardens, create hazards on the highways, and even pose threats to human health.

The Ecosystem Management Program is a good source of information on deer control.

Kangoroos Threaten One Of Australia's Last Original Grasslands
Australian Department of Defense is currently culling hundreds of kangaroos on the outskirts of the capital Canberra that have produced heated discussions and hit international headlines. Australia's iconic animal has multiplied so much over recent years that Canberra now has three times as many kangaroos as inhabitants. The situation is particularly critical at two enclosed military sites on the outskirts of the city, which form an ideal refuge for the eastern grey kangaroo (Macropus giganteus).

Mowing and Grazing Increase Prairie Species According to a long-term research study on tall grass prairies done at the Konza Prairie Research Natural Area by a trio of Kansas State University biology professors, bison grazing or mowing increases the species diversity or the number of plant species that exist at a particular site of grasses on the prairie. Grazing and mowing keep plant diversity high even in annually burned or fertilized prairie where some plant species would otherwise be lost.
