ForestInnov (Ivory Coast)

ForestInnov is a 25 ha (49 * 0.5 ha) experiment set up in 2019 in Ivory Coast, West Africa. Sixteen local species are tested in monoculture and over a gradient of functional diversity (2, 4, 8, 16 species mixture).

The main goals of this experimental site are the following:

  • Set up a tree diversity experiment in West Africa
  • Test mixture of indigeneous species that could be used by the National Forest Service for reforestation program
  • Demonstrate the economic feasability of an innovative technical itinerary where local farmers are associated to cultivate the field during the first years
