This article is about population control factors influencing population growth pdf non-humans. For the practice among humans, see Human population planning. Population control is the practice of artificially altering the size of any population.


It typically refers to the act of limiting the size of an animal population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology. This article needs additional citations for verification. Please help improve this article by adding citations to reliable sources.

Unsourced material may be challenged and removed. Population control can be influenced by a variety of factors. Humans can greatly influence the size of animal populations they directly interact with. Population control may involve culling, translocation, or manipulation of the reproductive capability.

The growth of a population may be limited by environmental factors such as food supply or predation. Snails, for example, cannot reproduce successfully in an environment low in calcium, no matter how much food there is because they need this mineral for shell growth. If the number of predators suddenly falls, the prey species might increase in number extremely quickly.

For example, all plants compete for light. Competition for territory and for mates can drastically reduce the growth of individual organisms. These may cause disease, and slow down the growth and reproductive rate of organisms within a population.
