Importance of the Harvest Method on the Regeneration of Combretaceae in the Senegalese Groundnut Basin. In order to develop recommendations for sustainable management of key fuel wood resources in the Senegalese Groundnut Basin, different diameters and heights of harvesting were tested on Guiera senegalensis J.F. Gmel and Combretum glutinosum Perr. The experimental design is adapted to the usual local harvesting period (May) and to the traditional tools (machete). Three factors were studied: species, height (ground level (RT), 20 and 50 cm) and diameter (0-10 and 10-20 cm). For each species, each treatment is represented by 15 individuals. Results from field observations and analysis of variance on the number of stems and growth variables (height and diameter) suggest a high survival rate (100%), a higher number of stems at 20 and 50 cm cutting height, a slow height growth of stems from ground level stumps (RT), and a larger diameter growth of G. senegalensis. For sustainable management of the studied Combreteceae species in the Groundnut Basin, 20 cm cutting height of all individuals would be appropriate.
