Interfaces Of Miombo Woodland Biodiversity And Local Community Woody Plant Species Use And Conservation Practices At Singida District Tanzania

A total of 117 woody plant species representing 81 genera and 34 families (34.2% and 65,8%rnshrubs and trees respectively) were collected and identified from the study area while 22 familiesrn(70 species) were reported to be highly utilized by the local community. The area was dominatedrnby species of the family Fabaceae (26.5%) followed by Combretaceae and Rutaceae (11% each).rnBrachystegici speciformis (IVI = 69.85) and Julbernardia globiflora (IVI = 51.2) were found tornbe the dominant tree species. About 41% stems of woody species were found in the reserved butrnnot in the unreserved land where by 97.74% and 61.7% of this proportion were recorded asrnstumps in the latter sites. 57.3% of the total woody plant species were highly utilized by the localrncommunity. On the other hand, other useful species such as Aerva lanata, Boscia massaiensis,rnSenna singueana and Lannea schweinfurthii var. stuhilmanii were locally extinct due to overrnexploitation. TWINSPAN has revealed six plant communities based on relative disturbances atrnvarious plots. There was a significant negative correlation between diversity and disturbance (r =rn-0.456 p= .000) and between richness and disturbance (r = -0.318, p= .001). One Way Analysis ofrnVariance (ANOVA) has exhibited that the six communities were statistically different withrnregard to their diversity (p = 0.000). Diversity was significantly high in the reserved area (p 20cm) (p= 0.0199) but no signinificant differences inrnthe poles (dbh class 4.1-10cm) (p= 0.1147) and seedlings and saplings (dbh class
