Community-based spring conservation in Catchment area of Kemalik Lingsar, Lombok, Indonesia

Water is the main and irreplaceable need for living things, both plants, animals and humans. Springs are one of the important elements, especially in the dry season, for the survival of living things, especially humans. The availability of water can play a role in many aspects including being able to function as drinking water, bathing, latrines (MCK), washing, plantations and livestock, irrigation of agricultural land, the need to purify oneself (as a support for the implementation of worship), and the economy. Conservation of springs through programmed reforestation activities in spring water catchment areas such as those carried out by the community and the NTB government requires precise references, so it is necessary to study the relationship or role between vegetation, soil (land) and climate in the conservation of spring sources. This research was conducted in Lingsar village, Lingsar District with quantitative research methods, namely observing vegetation directly in the field in the Kemalik Lingsar spring catchment area. Field data were then analyzed to determine the stratification, diversity, structure and composition of vegetation in the study area. The structure and composition of vegetation is carried out by calculating the density, frequency, dominance and importance of each species. Based on the research results it can be concluded that the number of tree species found in Kemalik is 14 species. Mangosteen is the dominant species with an IVI value of 104% and a density of 125 ph / ha. Utilization of land in the Kemaliq spring is mangosteen-based agroforestry which has been carried out for a long time, which can be seen from the old mangosteen trees which are planted at regular intervals and arrangements and are maintained (the community has long contributed to efforts to conserve soil and water). Underplants found in Kemalik were 16 species of herbaceous, 13 species of shrubs and saplings
