Ecological restoration in Wazo hill quarry is part of the activities going on under the Tanzania Portland Cement Company (TPCC).  A study done in Wazo hill showed that, Leucaena leucocephala has a positive potential in alleviating poverty of the local communities around the restored quarries through its use as fodder for meat and milk production from the livestock as the plant is known for its high protein value.  Still the influence of restoration process to the pollinators of this valuable plant species was unknown in this area.

The main objective of the study is to determine the influence of the ecological restoration on the diversity and abundance of the floral visitors and pollinators of the Leucaena leucocephala. This can be achieved by determining the abundance of  floral visitors and potential pollinators  of the Leucaena leucocephala, determining the diversity of the floral visitors and potential pollinators of the Leucaena leucocephala and evaluating the  time spent by floral visitors and potential pollinators of the Leucaena leucocephala the three study sites namely the  Restored site, un-restored site Un-mined site

 In each study site, three Leucaena leucocephala plants each with 80 flowers will be chosen randomly at each study day. During the study, the flower will be monitored for 5 hours from 9:00 1am to 14:00pm for partitioning of 20 minutes per treatment

It is our expectation that, this study will provide the clue for monitoring the pollinators in the Wazo hill quarry. Also, it will help the TPCC factory administration to incorporate pollinators in the integrated ecosystem management. The ecological knowledge in this area will be added. Pupils, local communities and university students will learn the importance ecological restoration for pollinators of Leucaena leucocephala and our daily food hence the company gaining support from public.   Also poverty alleviation of the local communities depending on crops through increased productivity from pollinators activities one of the outcome.
