Exploitation colonialism is the national economic policy of conquering a country to exploit its natural resources and its native population.
 The practice of exploitation colonialism contrasts with settler colonialism, the policy of conquering a country to establish a branch of the metropole (Motherland), and for the exploitation of its natural resources and native population.
 A colonialist power pursues settler colonialism to relieve the pressures of over-population upon the economy and the national territory of the motherland, and to extend its territory and culture by reproducing its society in other parts of the world.
 A reason for which a country might practice exploitation colonialism is the immediate financial gain produced by the low-cost extraction of raw materials by means of a native people, usually administered by a colonial government.
The Icelandic horse is a breed of horse developed in Iceland.
 Although the horses are small, at times pony-sized, most registries for the Icelandic refer to it as a horse.
 Icelandic horses are long-lived and hardy.
 In their native country they have few diseases; Icelandic law prevents horses from being imported into the country and exported animals are not allowed to return.
 The Icelandic displays two gaits in addition to the typical walk, trot, and canter/gallop commonly displayed by other breeds.
 The only breed of horse in Iceland, they are also popular internationally, and sizable populations exist in Europe and North America.
 The breed is still used for traditional sheepherding work in its native country, as well as for leisure, showing, and racing.

The Lady Bird Johnson Wildflower Center is a public botanical garden dedicated to creating a more sustainable earth through research and education.
 Situated 10 miles southwest of downtown Austin, Texas and just inside the edge of the distinctive Texas hill country, the 279-acre Wildflower Center attracts 100,000 annual visitors.
 The center is a self-supporting research unit of The University of Texas at Austin devoted entirely to native plants, with more than 700 species native to central Texas, and the environmental benefits of native-plant landscaping.
 (see Native Plant Information Network).
 The Wildflower Center also hosts changing exhibits of visual art and photography and features outdoor sculptures, walking trails, formal and research plantings, educational exhibits, and an annual sale of native plants.
 In 2013, the syndicated television series, "Texas Country Reporter", hosted by Bob Phillips, declared the center the No. 1 site from which to view wildflowers within Texas.

Many of New Zealand's birds are endemic to the country, that is, they are not found in any other country.
 Endemic species differ from native or indigenous species in that native or indigenous species have generally and historically, migrated to a region or country and become established over a long period of time, whereas endemic species, have only ever inhabited the region or country where they were first discovered.
 Approximately 71% of the bird species breeding in New Zealand before humans arrived are widely accepted as being endemic.

Indian country is any of the many self-governing Native American communities throughout the United States.
 As a legal category, it includes "all land within the limits of any Indian reservation", "all dependent Indian communities within the borders of the United States", and "all Indian allotments, the Indian titles to which have not been extinguished."
 This legal classification defines American Indian tribal and individual land holdings as part of a reservation, an allotment, or a public domain allotment.
 All federal trust lands held for Native American tribes is Indian country.
 Federal, state, and local governments use this category in their legal processes.
 Today, however, according to the U.S. Census of 2010, over 78% of all Native Americans live off reservations.
 Indian country now spans thousands of rural areas, towns and cities where Indian people live.
