In biology, overabundant species refers to an excessive number of individuals [1] and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
A red fox at the Great Otway National Park in 2019. Red foxes pose a serious conservation problem in Australia. 2012 estimates indicate that there are more than 7.2 million red foxes (Vulpes vulpes) [1] (and growing), with a range extending throughout most of the continental mainland. [2]
Population density (people per km 2) by country. This is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.

Juvenile red foxes are known as kits. Males are called tods or dogs, females are called vixens, and young are known as cubs or kits.
