The influence of protective regime, in the condition of spring fires in several years, on natural
degraded pasture areas at different stages of pasture digression was investigated under conditions
of the right Ob riverside forest-steppe during 1999–2013. It is shown that during protective regime
vitality of plants, firstly – long rhizome grasses, such as Poa angustifolia, Elytrigia repens and
Bromopsis inermis, has improved. The number of species of phytocenosis has increased in 1,3–
4,4 times, mainly at the expense of grasses and forbs. Annual and biennial weeds and weeds
with top root remain in an herbage, also there are microcommunities from not eaten rhizomatous
and root-sucker species. Phytocenosis productivity sharply increases in first two-four years, and
meteorological conditions of some years and intensity of accumulation of dead grass and mulch
exert considerable influence on stocks of green overground phytomass.
