The objective of this study was to develop species-specific volume models for thicket species and mixed-species volume models for associate trees in Itigi thicket. Data were collected through destructive sampling (60 thicket clumps): Combretum celastroides Laws and Pseudoprosopsis fischeri (Tab) Harms and (30 associate trees): Canthium burtii Bullock sensu R. B. Drumm, Cassipourea mollis (R. E. Fr.) Alston, Haplocoelum foliolosum L, Lannea fulva (Engl.) Engl and Vangueria madagascariensis J.F. Gmelin. Different nonlinear multiplicative model forms were tested, and models were selected based on coefficient of correlation (R2) and relative root mean square error (RMSEr). Large parts of the var
