1 RCMRD Presented By: RISPHA GICHEHA Land use/ cover mapping and boundary delineation of plantation and indigenous forests in Mount Kenya

2 RCMRD Member States Contracting members Non-Contracting member Regional Centre for Mapping of Resources for Development (RCMRD) Established in 1975 under UN-ECA Has 15 Member States: Botswana, Comoros, Ethiopia, Kenya, Lesotho, Malawi, Mauritius, Namibia, Seychelles, Somalia, Sudan, Swaziland, Tanzania, Uganda, Zambia and South Africa. The countries affiliated to the Centre are Angola, Mozambique, Zimbabwe, Rwanda, Burundi, Madagascar, Djibouti, Eritrea and DRC.

3 RCMRD Introduction  Mount Kenya is a shield volcano partly covered by dense indigenous and partly by planted forest around its foot.  second highest mountain in Africa (5,199m)  Base diameter of about 100 Km.

4 RCMRD Study Area Embu Indigenous Forest Plantation Forest Bamboo Forest Moorland Kirinyaga Meru South Meru Central Nyeri Kenya Ethiopia Somalia Tanzania Uganda Embu

5 RCMRD Objectives Map the land use/ cover in the area, especially forest Delineate the boundary between the plantation and indigenous forests Establish ground controls for management of the forest

6 RCMRD  Develop landcover map based on satellite image  Develop GIS Database  Determination of areas under indigenous forest, plantation forest and human encroachment  Establishment of ground control points Approach/ Methods

7 RCMRD Methods  Ancillary Data  Satellite Image processing and landcover mapping  Delineation of plantation and indigenous forests  Establishment of ground control

18 RCMRD Encroachment

19 RCMRD General Guideline:  Boundary should be kept as straight as possible  The physical infrastructure and equipment associated with the FD’s previous responsibilities should be assessed relative to the plantations  Animal breeding sites, watering points and salt licks should be designated as indigenous  In cases of steep escarpments, valleys ridges, there should be attempts to have the boundary follow contours  The more flat areas to be reserved for plantation forests Boundary Delineation of Plantation and Indigenous forests

20 RCMRD Proposed delineation versus plantations from plantation sheets Proposed delineation Plantation Forest District Boundary

21 RCMRD Proposed delineation versus plantations mapped from satellite imagery Plantations Proposed delineation District Boundary

22 RCMRD Proposed boundary between plantation and indigenous forests Proposed delineation Indigenous Forest Plantation Forest Bamboo Forest Moorland District Boundary

23 RCMRD Establishment of ground controls

24 RCMRD Output

25 RCMRD Conclusion  Time taken was shorter  Cost effective  Accuracy is high

26 RCMRD Recommendation  Training of the Forestry Department (FD) and Kenya Wildlife Service (KWS) field officers in GIS and Remote sensing  If the wild animals are to be completely enclosed in the indigenous Forest an electric fence should be used  It was observed that the forest reserve boundary has not been surveyed A fixed cadastral survey is therefore recommended to formalize the forest reserve boundary
