An ecological island is a term used in New Zealand, and increasingly in Australia, to refer to an area of land (not necessarily an actual island) isolated by natural or artificial means from the surrounding land, [1] where a natural micro-habitat exists amidst a larger differing ecosystem.
Island ecology is the study of island organisms and their interactions with each other and the environment. Islands account for nearly 1/6 of earth’s total land area, [1] yet the ecology of island ecosystems is vastly different from that of mainland communities.
The world-average ecological footprint in 2016 was 2.75 global hectares per person (22.6 billion in total). With a world-average biocapacity of 1.63 global hectares (gha) per person (12.2 billion in total), this leads to a global ecological deficit of 1.1 global hectares per person (10.4 billion in total).

English: World map of countries shaded according to their ecological footprint in 2006 (published on 25 November 2009 by the Global Footprint Network). It is measured by the amount of global hectares that are affected by humans per capita of the country.
A biogeographic realm is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions.
This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial , freshwater , and marine ecoregions . The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms , containing 867 smaller ecoregions.
Larger islands with diverse ecological niches encouraged floral and faunal adaptive radiation, whereby multiple species evolved from a common ancestor, each species adapted to a different ecological niche; the various species of Hawaiian honeycreepers (Family Drepanididae) are a classic example. Other adaptations to island ecologies include ...
While it is usually regarded as one of the most remote islands on Earth the island is actually only 320 kilometres (200 mi) from Gough Island. The island is instead known as the most remote inhabited island on Earth. Gough Island is uninhabited apart from a weather station with around 6–7 people on it but they are not a permanent population. [1]
