Overview

Evaluates changes in vegetation cover in semi-arid Niger, suggesting effective management of grazing ecosystems.

Key Points

  • The research aims to assess the structure and dynamics of plant cover in the Sahelian rangeland of Niger.
  • Conducted dendrometric and phytosociological surveys on 2,500 m2 plots.
  • Identified 16 plant species, including woody and herbaceous types.
  • Analyzed diameter class distributions and canopy heights.
  • Utilized NDVI MODIS to assess vegetation cover variability.
  • Identified dominant species as Poaceae and Fabaceae families.
  • Diameter class analysis showed 50% of woody plants were 20-35 cm in size.
  • The majority of trees fell within the 4-6 m height range (47.69%).
  • Therophytes made up 56.03% of identified biological types.
