Odzala is characterized by a rich variety of habitats, including primary rain forest with a closed canopy (e.g. with Entandrophragma utile, E. candollei and E. cylindricum) and open understorey layer, forests dominated by dense formations of Marantaceae, forest clearings and savannas on the hilltops (e.g. with Hymenocardia acida, Annona arenaria or Hyparrhenia diplandra).
