Résumé
Enabling local community participation in management is a key to stop alarming degradation in the Miombo woodlands. This study examined the socio-economic and ecological impact of participatory management practised in Bereku woodland, Babati district, Tanzania. Semi-structured questionnaire, focus group interview and field observation used for socio-economic study. Random sampling was done to select 10 percent of the households for questionnaire interview. While ecological data was collected by systematic sampling using transects of circular plots with different radius. Within 5m radius all trees with dbh  4cm ; within10 m radius all trees with dbh  10 cm and within 15 m radius all trees with dbh  20cm were identified and measured. The socio-economic results revealed significant satisfaction with management (P<0.05) Chi-square of (14.49). Remarkable synergies at household’s level were fuel wood, construction materials and environmental goods and services. At village level, strengthened institutions and revenue were outstanding. Ecological survey revealed 87 tree species in 37 families of 63 genera, Shannon index was higher, (3.8), Species diversity index (96). Importance Value Index showed Brachystegia microphylla (11.38), Brachystegia. speciformis (9.03) and Julbernardia globiflora (6.42) were the most important woodland tree species. Stocking was high (981 stems/ha), mean basal area (13.24m2/ha) but low mean volume (64.76 m3/ha). There is need to increase tangible benefits at household’s level and more strengthening village institutions.
