Mgambo Forest Reserve 6 2.0 AIMS OF THE SURVEY The specific aims of the biodiversity survey as outlined in the Terms of Reference between the Frontier Tanzania Forest Research Programme and the East Usambara Conservation Area Management Programme (EUCAMP) are: • to conduct biological baseline surveys in selected forests as a baseline against which to monitor future changes in biodiversity status; • to provide information on the biological value and importance of these forests in order to assist in the development of management plans and practices for these forests; • to provide information on human disturbance and levels of resource use in different areas of the forest; • to develop specific, quantitative methods of monitoring key biodiveristy indicators, and assist in establishing long term monitoring procedures to address specific aspects of the forest ecology and management such as regeneration and hunting; • to train Tanzanian personnel from EUCAMP, UDSM, the TAFORI and the Forestry and Bee Keeping Division in forest survey work; • to contribute to global biodiversity assessment and conservation efforts through collaboration with specialists elsewhere, and the sharing of information, data and material collected during surveys. Furthermore, the aims of the survey methods applied are: • to sample the vegetation and tree species composition of selected forests of the East Usambara Mountains using systematic sampling techniques along systematically located vegetation transects, which sample 0.25% of the area of each forest reserve; • to assess levels of disturbance by systematically sampling the incidence of tree cutting, animal trapping and other illegal activities along the vegetation transects; • to use standardised and repeatable methods to record biodiversity values of the forest in terms of small mammal, reptile, amphibian, and invertebrate species; • to collect opportunistic data on all other groups of vertebrate and invertebrates. Species lists resulting from this will be compared against IUCN categories of threat and other conservation criteria in order to assess the overall biodiversity values of each forest. By using standardised and repeatable methods these surveys provide an assessment of the biodiversity value of the forests, enabling their importance to be determined and their biodiversity value to be monitored in future. An additional aim of the project that is covered in a separate report includes: • to provide small scale feedback with regard to the survey findings through environmental education activities within school and village committee networks, in co-operation with the EUCAMP Village Forestry Programme.

Mgambo Forest Reserve 7 3.0 DESCRIPTION OF THE FOREST 3.1 General description 3.1.1 Description Name: Mgambo Forest Reserve Muheza District, Tanga Region, Tanzania. Area: 1346 ha Status: Catchment Forest Reserve Gazetted July 1998 as delineated and described on Forest and Bee Keeping Division Map No. Jb. 2291 Gazettement notice GN 99 (1931; (1995). Central Authority Status Maps: Ordnance Survey topographic maps 1: 50 000 Series Y742 (D.O.S. 422) Sheet 110/4 ‘Gombero’ of 1989 and Sheet 110/2 ‘Mwakijembe’ of 1989 Forest and Bee Keeping Division maps: Jb 2291 1996 ‘Mgambo Forest Reserve’ 1:10,000 3.1.2 Location Lat/Long: S 04°44'53" - S 04°47'50", E 38°47'18" - 38°49'11" E UTM/UPS: 94 75228 - 94 69784 S, 04 76554 - 04 80020 E Elevation: 320m – 820m above sea level Mgambo Forest Reserve (FR) is located in the north-east of the main East Usambara Mountain range with Mpanga and Mtai forest reserves to the south. Mgambo FR lies adjacent to the savanna plateau that reaches into Kenya (Figure 2). Mgambo FR covers an area of 13.46 km 2 (1346 ha). It lies in the district of Muheza, Maramba Division, Tanga Region and covers land approximately 10 km north from Maramba town, located on latitude 4 o 46'00" and longitude 38 o 45'15". Mgambo FR was gazetted in July 1998, as delineated and described on the Forest and Beekeeping Division map number. Jb. 2291. It was gazetted primarily to protect the catchment areas supplying Bwiti, Mavovo, Mgambo and Daluni villages. The region has an average annual rainfall of the area is between 1000 and 1500 mm per year falling principally from March to June although, in recent years, rain has been unpredictable and low. Vegetation cover within Mgambo Forest Reserve has previously been recorded as containing 1,295 ha of poorly stocked lowland forest and 51 ha of cultivation under lowland forest (Johansson, 1996). 3.1.3 Topography Mgambo FR consists of two ridges running north to south in the western and eastern halves of the reserve (Figure 3). A photograph of the view from a northerly point along the eastern ridge top can be found in Figure 1. The ridge top reaches an altitude of 800m above sea level. All but one or two rocky cliff areas is accessible by foot. There is a water source feeding Bwiti village and subvillages and another that is used by Mgambo village.
