This is a documentation of various mechanisms of small-island ecosystem along environmental conservation which are dependent on their gained sound knowledge and understanding of their environment and the underlying ecological processes that formed the foundation for their well-being and environmental conservation. A mixture of qualitative and quantitative methods for data collection and analyses were employed. Common qualitative techniques like observation, key informants interview, focus group discussion and quantitative techniques like monitoring and measurement of runoff, sediment load and seagrass and net primary productivity (NPP) were used. Significant findings pointed that small-island ecosystems’ coconut-based cropping system showed positive significant relation to the type of vegetation. Maximization of farm animal waste in sustaining fertility of the agricultural land resulted to the good quality of water with tolerable total suspended and dissolved solids and animal sedimentation rate from agricultural areas. The low rate of sedimentation and better quality of runoff water increased the seagrass NPP and high fish productivity, indicators of efficient islanders’ livelihood practices and significantly conserve the coastal subsystem and subsequently the whole island ecosystem. The main threat to the coastal subsystem was exceedingly high coliform count which urges the promulgation of municipal ordinances and programs in relation to environmental health.
