Fallow Lands of Tuva: 30 Years of Steppe Demutation

Main Content:

The Study at a Glance

  • Research focuses on 30 years of steppe demutation in Tuva, Russia.
  • Examines differences between virgin steppes and secondary steppes.
  • Analyzes 330 geobotanical releves for species composition, dominant species, grass cover, and height.

Key Findings

  • Vegetation Transition: The study confirms that secondary steppes significantly differ from virgin steppes in species composition and structure.
  • Species Richness: Virgin steppes exhibit higher species richness compared to their fallow counterparts.
  • Grass Cover & Height: Grass cover in virgin steppes is denser, while secondary steppes feature taller grass.
  • Dominant Species Shift: While some species persist, fallow lands tend to develop different dominant species compared to virgin steppes.

Ecological Implications

According to the research, the restoration process follows general ecological patterns, where wetter habitats show higher species diversity. However, fallow lands in desert steppes exhibit unexpected species richness.
