Conservation Area (CA) provides us with numerous environmental services and public livelihood, while plays a significant role in the economic development from local to national scope interest. Parallel with, promoting nature for ecotourism destination is one of their product, as Indonesia government aims to develop tourism sector, has set Conservation Areas to attract and aid approximately 20 million (domestic) and 1.5 million (international) entrance until 2019. Seeing the fact, conservation areas, forests have multifunctional uses based on economic, environmental, recreational, and social demands and values, which can lead to long-term conflicts in management. Thus, temporal forest cover changes can remodel entire related ecosystems. Although tourism development is highly profitable and has a multiplier effect on local economic growth, tourism also may have it downsides. This research corresponds on temporal basis to monitor transformational condition of forest coverage due to tourism activity in CA. <br /> <br /> In this research, CA. / Nature Parks in west Java, Indonesia selected as a case study area, with the support of GIS and Remote Sensing (RS) technology, forest-cover changed in 2005, 2009, 2013, and 2017 were observe. In Current study, using image differencing method with pixel based and post NDVI classification, resulting area of change and no change after differencing, will highlighted the area of change. NDVI post-classification viewing both forest loss and forest flourishing at the same time. From 2005 to 2009 to 2013 and all the way to 2017 the cover changed in forest stand, mainly occur in in periphery area of the parks and where mostly the tourism activity take place, that may reflect that change may be happening due to routine activity around the location. It is rare to have cloud-free Landsat scene dataset, that puts cloud-free data acquisition for a single date is difficult part of the process especially for the whole area we want to investigate. On preprocessing process of optical satellite images, cloud detection put in high-priority. miscalculate to mask out the clouds and haze from the Landsat scene, cause a serious contravening impact on any following analyses. However, it is doable of using the GIS Product to manipulate a masked or hidden an area within a data set. Thus, from this changed area, we tried to compare the result using correlation statistic method, to investigate, whether the forest cover may have been correlated with tourism activity around the location. When compared with visitor’s number around the location, the we find out that the r coefficient around 0.35, which reflect as a weak uphill (positive) linear relationship, that indicates lower interaction between both variables. <br /> <br /> Finally, with the potential to reveal most of landscape change including deforestation information and other forest disturbance activity, CA managers and local governments have more room to add, on maximizing the use of GIS based product, for tourism planning and environment protection policies making by applying more functionality of this detection change practice for keeping track of their vast managed area more effectively. <br /> <br /> <br /> Keyword: Conservation Area, forest cover change, GIS, NDVI, tourism effect <br /> <br />
