Description

  • The authors collected data on the seedling density and regeneration processes of 5 species of Combretaceae across latitudinal gradients in the Sahelo-Sudanian ecoregion in Burkina Faso. The species were chosen based on their economic importance and large distributions.
  • Rainfall varies across the area studied from 400-900 mm annually with elevations of about 300 m.
  • The vegetation in the area is strongly seasonal with mostly deciduous trees and most herbacious species dying back during the dry season.
  • Data was collected during the rainy season along transects at sites in the sampling area and regeneration mechanisms were determined by digging up individuals.
  • Seedling death could be attributed to climatic factors, predation, fire, and pathogens. In some areas, there were few observed mature individuals to provide a seed source.
  • Latitude had a significant effect on the density of seedlings of different species. Different species also showed differences in the regeneration mechanism.
  • These results show that species choice for reforestation in this region must be done on a site specific basis.
