Birds have a fairly wide living habitat, including water-falls. Curup Tenang is a waterfall tourism site which has a wildlife habitat suitable for birds. In The Curup Tenang tourism site, the number of visitors has decreased over years. Birds are one of the wildlife animals that have ecological values, potential tourism, and cultural values. The diversity of birds in this tourist location have not been recorded. Meanwhile, by increasing knowledge and data-bases regarding the diversity of birds in this area can be an addi-tional reference for the development strategy in the Curup Tenang tourism site so that it becomes a distinctive attraction for visitors. This study aimed to determine the diversity of birds that never been recorded before and to conduct a potential support of avitourism activities. The results of this study can be used as a guideline to study the potential of avitourism. The diversity of birds found in Curup Tenang consisted of forty-eight species belong to twenty-seven families, while three of them cited as protected bird species. This study concluded that Curup Tenang contains a high diversity of birds and it has a great potential to be developed into an attraction of tourism.

CCMRS-IPB conducted coral reef rehabilitation at damaged coral reefs around Nyamuk Island. Those artificial reef buildings for rehabilitation gave shelter spaces for reef fish. This research aims to calculate the effect of coral reef-building, which enhances rugosity to the reef fish diversity around the rehabilitation sites. The study was conducted on Nyamuk Island in the Anambas Islands. Reef fish were sampled annually from 2014 to 2019 using the underwater visual census. The Diversity index and non-Metric Multidimensional Scaling were built to discover reef fish diversity, and reef fish species were affected the most. Yearly data shows an escalation number of reef fish abundance and richness at the end of 2019. The major reef fish group is found to have constant diversity throughout the year compared to other functional groups. The target reef fish group came to this rehabilitation ecosystem primarily attracted by nourishment availability. There is a shift in the reef fish diversity from the early year to the project end. Generally, major reef fish groups will be refuged first around the rehabilitation sites, especially territorial types. Target fish groups from herbivorous and carnivorous types will mostly come along after their food availability and location to get around.

The coral growth rate is affected by several ecological conditions, which could lead to enhancement or deceleration. Good marine habitat and water conditions would escalate coral fragment growth rate on rehabilitation sites. This study was assessed to determine the coral growth rate transplanted on artificial reef-building for rehabilitation purposes and indicated the main driving factors that enhance coral growth rate at Nyamuk Island, Anambas. Benthic communities, coral length, and coral growth rate compared through the year. Analysis of variances and Principal component analysis (PCA) was conducted to indicated differences between variables and analyse driving factors of coral growth rate. Hard coral and sand coverage increasing during observation. Coral length based indicated constant escalation. However, coral growth yearly showed fluctuation with peak growth from 2014 to 2015. PCA exhibited hard coral, dead coral with algae, sponge, and sand played an important role in supporting coral growth on rehabilitation at Anambas. Available niche for other marine faunas built by artificial reef-building could support to preserve of the coral fragments. Acquisitions of hard coral by coral fragments could be supported by good natural hard coral coverage in the habitat. Herbivorous is one factor that could support recent coral reefs.
