Definition of Edge Effect

Edge effect is an ecological term that is the changes in the structures of populations and communities that take place at the boundary of two or more than two habitats. The areas that have small habitats depict prominent edge effects which are extended throughout the range. Due to the increased edge effects, the habitat allows greater biodiversity.


Edge effects are of the following types: inherent, induced, narrow, wide, convoluted, and perforated. Human activities such as agriculture, urbanization, pollution, fires, etc. also become a source of these edge effects. These changes pose damage to the habitat as well as the inhabitants.
