Introduced animal species recorded in the prairies include earthworms of the genus Aporrectodea and Asian beetles of the genus Popillia. In the prairie-forest border, the emerald ash borer, or Agrilus planipennis, and the hemlock woolly adelgid, or Adelges tsugae, are Asian invasive species, which cause damage to the vegetation. Among the vertebrates are the European starling, or Sturnus vulgaris, and the ring-necked pheasant, or Phasianus colchicus, which competes for food with the greater prairie chicken, or Tympanuchus cupido, a native endangered species.
The pampas are found primarily in Eastern Argentina, but also in Uruguay and in a small area of South Brazil. Animal species introduced into the pampas include the European hare, or Lepus europaeus; the wild boar, or Sus scrofa, native to Europe and Asia; the blackbuck, or Antilope cervicapra, which is native to the Indian subcontinent; and a species of squirrel from Southeast Asia, or Callosciurus erythraeus.
The large majority of introduced species in the the South African temperate grasslands are plants. However, non-native animal species found in the veld include the dark Argentinian ant, or Linepithema humile; the European starling, or Sturnus vulgaris; the house sparrow, or Passer domesticus, native to the Mediterranean region; the black rat, or Rattus rattus, which is native to Asia and Himalayan tahr, or Hemitragus jemlahicus, a relative of the wild goat.
Most animals introduced to the Eurasian steppes are located near human settlements, including the muskrat, or Ondatra zibethicus, which is native to North America; Sladen's rat, or Rattus tanezumi, and the brown or Norway rat, or Rattus norvegicus. Introduced invertebrates include the American white moth, or Hyphantria cunea; the American rice water weevil, or Lissorhoptrus oryzophilus; and the German cockroach, or Blattella germanica.
