Stakeholder Identification & Analysis Stakeholder activities were identified by direct observation and informal interviews. Observations such as counting and categorising fishing vessels were carried out in situ during surveys on the study sites. Stakeholder interviews were conducted both within and outside the study sites. IV. Results A. Nyororo Island Marine Reserve (NIMR) 1. Reserve Mapping A prototype patch mosaic was created using the high resolution satellite image (Figure 3). The data collected at NIMR, through transect, spot checks and manta tows, were used to describe the identified patches using the methodologies described. Initial data collection demonstrated that there was a greater diversity of patch types than initially delineated. The final habitat patch mosaic was created using all the ground proofing data collected. Final patch types included additional types such as areas dominated by or including macro algae, coralline rubble and a variety of different mixed habitat types.
The mapping process has described the shape and extent of the main terrestrial, tidal and marine habitats within the reserve area. The final habitat map created included six major patch types, ranging from reefs dominated by Acropora corals, through seagrass beds, to mixed macroalgal environments. Figure 3.
