Résumé
I assessed social and ecological acceptability of commercializing Colophospermum mopane seeds from Namibia through 262 interviews and ecological surveys of over 600 C. mopane trees at seven sites. I found high interest in and no cultural restrictions on C. mopane seed harvest, but limited local knowledge about C. mopane phenology. C. mopane seed uses included medicine and fragrance. Average C. mopane seed abundance/ha ± SE within villages was 27,434 ± 4669 ; the average human harvest rate was 1.5 ± 0.1 kg seeds/hr. Population structure differed among sites, seed abundance did not. C. mopane size best predicts seed production (df = 1, X2 = 55.8, P < 0.001) compared to other characteristics. Recruitment from C. mopane seed was low, vegetative reproduction was high. Vertebrate seed predation was minimal. My results suggest that local non-profit organizations should proceed with C. mopane seed sourcing and adaptive management to ensure C. mopane population sustainability.
