Background. The work is devoted to the description of halophytic vegetation, very rare for the forest-steppe zone of Eastern Europe, by the example of “Man-surovsky solonetz”, which has been recently discovered in the south-west of Penza region.
Results. Halophytic vegetation in this area covers 61 % of the territory and is represented by halophytic meadows (3 association) and halophytic steppes (4 as-sociation). The are feautires very rare halophytic flora and vegetation which are at various stages of demutation and degradation of the vegetation cover. The authors have determined basic stages of halophytic vegetation recovery after human disturbances.
Conclusions. To save the rare halophytic vegetation in the conditions of Penza region it is suggested to organize a nature sanctuary in Neverkinsky District near the village of Mansurovka called “Mansurovsky solonetz”.

forest-steppe zone, halophytic vegetation, demutation and degradation of vegetation cover, “Mansurovsky solonetz”.
