Mwea National Reserve is today co-managed between Kenya Wildlife Service and Mbeere County Council through a Memorandum of Understanding (MoU). An Advisory Committee oversees the implementation of management plans of the Reserve making these arrangement to be unique in comparison with other Reserves.
Mwea National Reserve Trust was founded in 1991 with the aim of soliciting funds to develop the reserve. Quite a number of projects have been funded through donations from well-wishers including a boat and out-board engine, energy saving jikos, translocating of Zebras and many others.
In 1991, the British, jointly with KWS constructed three bridges and graded most of the Reserve roads, helped in the construction of two classrooms at Namuri Primary School.
