List of introduced bird species: This list of introduced bird species includes all the species of bird introduced to an area without regard to that territory being or not being their native area of occupation or the success of that re-introduction or introduction to the area.  This practice has been harmful in many areas, although some introductions are made with the aim of preserving bird species.  Following the name of the bird, a brief description of where they were introduced is included.

Sports teams named Redskins: Sports teams named "Redskins" are part of the larger Native American mascot controversy regarding the use of Native American names, images and symbols by non-native sports teams.  Teams of this name have received particular public attention due to the fact that the term "redskin" is now generally regarded as disparaging and offensive.

Gesneria: Gesneria is a genus of approximately 50 species in the flowering plant family Gesneriaceae.  Except for two or three odd South American species, all are native to islands of the Caribbean.  The genus is classified in the tribe Gesnerieae along with the genera "Bellonia", "Pheidonocarpa", and "Rhytidophyllum".  "Gesneria" species are usually woody shrubs or subshrubs, and (with the closely related "Rhytidophyllum") are unusual in the family in having alternately (rather than decussately) arranged leaves.  A complete list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.

List of introduced mammal species: This list of introduced mammal species includes all the species of mammal introduced to an area without regard to that territory being or not being their native area of occupation or the success of that re-introduction or introduction to the area.  This practice has been harmful in many areas, although some introductions are made with the aim of preserving mammal species.  Following the name of the mammal, a brief description of where they were introduced is included.

Salvia gesneriflora: Salvia gesneriflora (sometimes spelled Salvia gesneriiflora) is a herbaceous perennial or subshrub native to mountainous provinces of the Sierra Madre Oriental in Mexico, growing at 7,500-10,000 ft elevation.  It was named in honor of 15th century Swiss botanist Conrad Gessner, for whom the genus "Gesneria" and family Gesneriaceae are also named.  The long tubular flowers of this salvia resemble "Gesneria" flowers.  It is a popular ornamental plant.

Bactris: Bactris is a genus of spiny palms which is native to the Mexico, South and Central America and the Caribbean.  Most species are small trees about 2 m tall, but some are large trees while others are shrubs with subterranean stems.  They have simple or pinnately compound leaves and yellow, orange, red or purple-black fruit.  The genus is most closely related to several other spiny palms—"Acrocomia", "Aiphanes", "Astrocaryum" and "Desmoncus".  The fruit of several species is edible, most notably "B. gasipaes", while others are used medicinally or for construction.

Hyssopus (plant): Hyssopus (hyssop) is a genus of herbaceous or semi-woody plants in the family Lamiaceae, native from the east Mediterranean to central Asia as far east as Mongolia.  They are aromatic, with erect branched stems up to 60 cm long covered with fine hairs at the tips.  The leaves are narrow oblong, 2–5 cm long.  The small blue flowers are borne on the upper part of the branches during summer.  By far the best-known species is the herb hyssop ("H. officinalis"), widely cultivated outside its native area in the Mediterranean.

Chief Wahoo: Chief Wahoo is a logo of the Cleveland Indians, a Major League Baseball (MLB) franchise based in Cleveland, Ohio.  The logo is a cartoon caricature of a stereotypical American Indian face.  As part of the larger Native American mascot controversy, it has drawn criticism from American Indians, social scientists, and religious and educational groups, but remains popular among fans of the Cleveland Indians baseball team.  The team considered replacing the logo in 1994 when it moved to Jacobs Field (later renamed Progressive Field), but it was ultimately retained.  In 2013, Wahoo was replaced as the team's primary cap logo with a block "C", but still appears on the team's uniforms' sleeves and their home baseball caps.  Although Chief Wahoo is most properly described as a logo, he is sometimes called a mascot.

Austrocedrus: Austrocedrus is a genus of conifer belonging to the cypress family Cupressaceae.  It has only one species, Austrocedrus chilensis, native to the Valdivian temperate rain forests and the adjacent drier steppe-forests of central-southern Chile and western Argentina from 33°S to 44°S latitude.  It is known in its native area as ciprés de la cordillera or cordilleran cypress, and elsewhere by the scientific name as Austrocedrus, or sometimes as Chilean incense-cedar or Chilean cedar.  The generic name means "southern cedar".

European perch: Perca fluviatilis, commonly known as the European perch, perch, redfin perch, big-scaled redfin, English perch, Eurasian perch, Eurasian river perch or common perch, is a predatory species of perch found in Europe and northern Asia.  The species is a popular quarry for anglers, and has been widely introduced beyond its native area, into Australia, New Zealand, and South Africa.  They have caused substantial damage to native fish populations in Australia and have been proclaimed a noxious species in New South Wales.
