Overabundant Species

In biology, an overabundant species is one whose population has grown to an excessive number of individuals, exceeding what would be considered a normal population density for it. Population increases of this kind are driven by several factors, including habitat destruction or modification by people, the introduction of invasive species, and the reintroduction of once threatened species into protected reserves where they then thrive unchecked. Overabundance can harm both the surrounding ecosystem and human welfare, and it is managed through methods such as hunting, contraception, chemical control, disease, and genetic modification. Research on the subject has concentrated overwhelmingly on the damage overabundant species cause, with the potential for any positive effects left largely unexamined.
