Ulmus pumila
Ulmus pumila, or Siberian elm, is a deciduous tree native to Central and East Asia. It is drought-tolerant and widely planted beyond its native range.
Elm: Elm is the common name for trees in the genus Ulmus, many of which have toothed leaves and winged fruits. Siberian elm is one species within this tree genus.
Windbreak: A windbreak is a row or belt of trees or shrubs planted to reduce wind speed across land. Siberian elm has been planted in exposed landscapes for shelter.
American elm: American elm is a large North American tree, Ulmus americana, known for its vase-shaped crown. It is a native North American elm often compared with planted Siberian elm.
Biological invasion: Biological invasion is the spread of organisms beyond their native ranges, often with ecological consequences. Siberian elm's spread beyond Asia exemplifies plant invasion.
Samara: A samara is a dry, winged fruit that disperses a seed by wind. Its round, winged fruits distinguish Siberian elm from elms with hairy seeds.
Urban forestry: Urban forestry is the planning and care of trees in and around towns and cities. Its tolerance of drought and poor soils has made it an urban planting choice.
Chinese elm: Chinese elm, Ulmus parvifolia, is an East Asian tree with small leaves and mottled, exfoliating bark. It is another Asian elm used in landscaping, but differs in bark and growth habit.
Tallgrass prairie: Tallgrass prairie is a North American grassland ecosystem dominated by tall grasses and historically maintained by fire. Siberian elm can establish in prairie remnants and change their open structure.
Deciduous plant: A deciduous plant sheds its leaves seasonally, usually in response to cold or dry conditions. Siberian elm loses its leaves before winter in much of its range.
Invasive species: An invasive species is a non-native organism that spreads and causes ecological, economic, or other harm. Siberian elm escapes cultivation and is invasive in parts of North America.
