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.
Easter Island has been a site of dramatic ecological change. Today there are over 500 million people on islands, all dependent on local resources either directly (traditional use) or indirectly (ecotourism revenue). Population growth and development result in heavy deforestation, pollution, and over-exploitation.
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 ...
This is a list of countries by ecological footprint. The table is based on data spanning from 1961 to 2013 from the Global Footprint Network's National Footprint Accounts published in 2016. Numbers are given in global hectares per capita. The world-average ecological footprint in 2016 was 2.75 global hectares per person

One example is the rare Torrey pine (Pinus torreyana), which is only native to the coastal bluffs in Torrey Pines State Natural Reserve near San Diego, and off the coast on Santa Rosa Island. [4] Another example is the Tecate Cypress ( Cupressus forbesii ), which only occurs in four stands near the Mexican border of California.
The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals .
The European Environmental Agency (EEA) divides Europe into a total of eleven terrestrial biogeographical regions and seven regional seas. [1] The agency has issued the Digital Map of European Ecological Regions (DMEER), and operates with a total of 70 ecoregions, of which 58 are within the European continent .
