The study was undertaken to investigate the utilization of wild plants by local communitiesrnalong the Kwakuchinja wildlife corridor in Tarangire-Manyara ecosystem, Tanzania. Tornaccomplish this, an ethno-botanical survey was carried out in the two villages found within therncorridor, Minjingu and Vilima Vitatu. The surveys involved an assessment of plant use,rnprefen'ed species and their availability. This was combined with vegetation study. Ecologicalrnstand parameters inside and outside the National Park were compared and related to the levelrnof exploitation. This was done with special observation on the mentioned useful plantsrnencountered in the field. Data analysis was aided by Computer Programs and Statisticalrnpackages including INSTAT, Microsoft excel and SPSS VI1. The vegetation study revealedrnthat the wood component in the study area was dominated by the genera Acacia, with highestrnabundance of Acacia tortilis and Acacia kirkii, while the field layer was predominantlyrnDacty/octellilllll aegyptilllll and Thellleda trialldra. These were interspersed with a tree/shrubrnlayer of Maerlla triphylla among others. During ethnobotanical survey, 64 useful plant speciesrnwere mentioned out of which only 24 were encountered in vegetation survey. The uses werernaltogether classified into eight categories and major uses were medicinal, constlUction,rnfirewood and food. As expected, there was a clear pattern of species diversity following thernlevel of disturbance, whereby plots closest to settlements, hence highest disturbance, hadrnlowest diversity index and those relatively at a distance, with intelmediate disturbance hadrncomparatively the highest diversity. This pattern aligns with the Intermediate DisturbancernHypothesis, which states that diversity will be highest at sites that have had an intermediaternfrequency of disturbance and will be lower at sites that have experienced very high or velYrnlow disturbance frequencies.
