Over Cropping


 
 
Concept Explanation
 

Over Cropping

Overcropping of animal populations means killing more animals than can be replaced by the normal breeding cycle. This results in a decrease in the population. Many of the world's whale populations have declined dramatically as a result of over cropping. The population of the blue whale in the 1980's was only about 5 per cent of the population earlier in the century. Blue whales are not totally protected, but populations are recovering very slowly.

One of the important roles for ecologists is to find out how many animals can be removed from a population without endangering the survival of the species. Regulations control how many animals may be taken. These regulations vary for different species.
