Grasslands of the world
earlier, vegetation is much determined by the frequency, duration and depth of
flooding, as well as by the degree and quality of silt sedimentation. All sorts of
classifications have been thought out. Prolonged flooding over 40 days or more
is withstood by Phalaris spp., Bromus inermis , Stipa pratensis and many Carex
spp. (Table 10.5). Prolonged flooding is the rule in the floodplains of the greater
steppe rivers (Dnepr, Don, Volga, Ural). Salination (solonchaks) is common in
the outer reaches (upper flood meadow s).
Three major zonal strips can be distinguished:
