Definition of Species Diversity

Species diversity is an ecological term that is defined as the number of species that are existing in a specific region. It also deals with the abundance and relative abundance of each species that live in that particular region. Species diversity can be studied on a large as well as on small scale.


Species diversity is very important for the survival of the ecosystem as each species is contributing something to the ecosystem. They may be a source of food and may contribute to water, soil, and air. They may have a significant role in reducing pollution and stabilizing the environment. In this way, if one species vanishes, the ecosystem would undergo some kind of disturbance.
