ERZURUM ● Turkey
Description: A. cristatum is a densely tufted grass, with culms ranging from 30–50 cm high at maturity. Its sheaths are scabrous or the lowest ones pubescent. Its blades are up to 8 mm wide, and scabrous to pubescent above. Its spikes are flat and range from 2–7 cm long., with spikelets ranging from 8–15 mm long, being 3-5-flowered, densely crowded, and spreading to ascending. Its glumes are 4–6 mm long, awn-tipped, and its lemmas are 6–8 mm long and either awnless or awn-tipped.
Biology: Agropyron cristatum is a known among other grasses and wheats for its relatively high granivory. Granivory, or granivores, describe the interaction between animals and seeds. Agropyron cristatum's high granivore indicates that animals feed on the seeds of the plant as their primary, or even exclusive, food source.
Habitat: Dry areas such as steppes and dry grassland. It prefers warm, loose loam-, loess-, sandy, soils rich in alkaline minerals. A. cristatum is a highly competitive and persistent plant in drier areas. It can be grown in cold temperatures, drought conditions, and relatively high amounts of salinity.
Distribution: Agropyron cristatum is native to middle, east, southeastern and southwestern Europe, as well as many parts of temperate Asia. It has a widespread distribution, overall stable subpopulations and does not face major threats in the core of its range. However, it is threatened in some European countries, as it is mainly at the northwestern limit of its range, and needs local conservation attention. It is therefore regionally assessed as Least Concern.
It was introduced from Russia and Siberia to North America in the first half of the twentieth century.
