Abstract

Steppes, pusztas, prairies, savannas, the Pampas and other natural ecosystems function on one biological principle: they are multicomponent, self sustaining within a certain flora (and fauna) biodiversity, vertical structure, zone associations, dominants, bioproductivity (yield) and erosion resistance. Fully degraded steppes and the analogues slowly reestablish over succession stages- within 80-100 and more years.
