[1] Many farms have a field border, usually composed of a strip of shrubs and vegetation, used to provide food and cover necessary for the survival of wildlife.
It has been found that these borders may lead to an increased variety of animals and plants in the area, but also in some cases a decreased yield of crops.
[2] In Australian and New Zealand English, any agricultural field may be called a paddock, especially if for keeping sheep or cattle.
A back paddock is a smaller field that is situated away from the farm house; possibly land of lesser quality.
In a new style of intensive farming developed in North America, a paddock is a small (perhaps 1 acre) temporary subdivision of a pasture made with electric fencing, which is intensely grazed for a day and then left to rest for perhaps 80 days or more.
