Persepsi Masyarakat Lokal Terhadap Pengembangan Hutan Mangrove Sebagai Kawasan Ekowisata Di Kampung Ruar Distrik Biak Timur Kabupaten Biak Numfor

The mangrove forest area of Kampung Ruar, East Biak District, is an area that has traditionally been a place for fishing and lime-making efforts by the community who have been hereditary. This condition raises questions from various parties whether this location is suitable to be developed as a mangrove ecotourism destination. Development of Mangrove Ecotourism by the Papua Provincial Forestry Service as a tourist attraction by utilizing local natural potential and supporting tourism policies in Biak Numfor Regency. This study aims to see the socio-cultural conditions of local communities in the Mangrove Forest Area of Kampung Ruar, Biak Timur District, Biak Numfor Regency as an ecotourism area and to assess the local community's perceptions of the development of ecotourism areas in providing benefits to the community both economically and socio-culture in Kampung Ruar Distik Biak Regency. Timur Biak. The study hasli revealed that the perception of local communities about ecotourism (60%), community knowledge about resources (70%) and understanding of community knowledge about forest damage and aspects of forest protection are very good (67), most (49%) people who understand that the potential for ecotourism development has future prospects. The four alternative strategies for mangrove ecotourism in Kampung Ruar, Biak Timur District, Biak Numfor District in Kampung Ruar are as follows: (a) Development of a Tour Package between Mangrove Ecotourism and TBTA Biak; (b) Increase Knowledge and Community Empowerment; (c) Mangrove Rehabilitation and Community Empowerment; and (d) Mentoring and involvement of local communities in management

An annotated bird checklist for Gam island, Raja Ampat, including field notes on species monitoring and conservation

Species checklists are a fundamental component of biodiversity research. They foster understanding of species distributions and habitat preferences, thus reducing gaps of knowledge in geographical occurrences of species. Especially in light of the limited availability of data on species distributions for Tanah Papua, an increasing scientific focus on the region is crucial to foster and refine the knowledge of species occurrences and to inform potential conservation planning. Despite a strong focus on conservation of Raja Ampat´s marine areas, surprisingly few studies have focused on the terrestrial biodiversity of the archipelago. As a consequence, detailed species checklists are largely missing. Here, we provide a preliminary bird species checklist for the island of Gam and its surrounding islands, located in the central Raja Ampat archipelago. During nine sampling periods between 2013 and 2019, we recorded 132 bird species in six distinct habitat types. Of the detected species, six are considered threatened by IUCN Red List criteria. We further recorded three new species for Gam Island, thereby expanding their known extent of occurrence

Life‐history dimensions indicate non‐random assembly processes in tropical island tree communities

Community assembly processes on islands are often non‐random. The mechanisms behind non‐random assembly, however, are generally difficult to disentangle. Functional diversity in combination with a null model approach that accounts for differences in species richness among islands can be used to test for non‐random assembly processes, but has been applied rarely to island communities. By linking functional diversity of trees on islands with a null model approach, we bridge this gap and test for the role of stochastic versus non‐random trait‐mediated assembly processes in shaping communities by studying functional diversity–area relationships. We measured 11 plant functional traits linked to species dispersal and resource acquisition strategies of 57 tree species on 40 tropical islands. We grouped traits into four life‐history dimensions representing 1) dispersal ability, 2) growth strategy, 3) light acquisition and 4) nutrient acquisition. To test for non‐random assembly processes, we used null models that account for differences in species richness among the islands. Our results reveal contrasting responses of the four life‐history dimensions to island area. The dispersal and the growth strategy dimensions were underdispersed on smaller islands, whereas the light acquisition dimension was overdispersed. The nutrient acquisition dimension did not deviate from null expectations. With increasing island area, shifts in the strength of non‐random assembly processes increased the diversity of dispersal and acquisition strategies in island communities. Our results suggest that smaller islands may be more difficult to colonize and provide more limited niche space compared to larger islands, whose tree communities are likely determined by stochastic processes and higher niche diversity. Our null model approach highlights that analyzing the functional diversity of different life‐history dimensions provides a powerful framework to unravel community assembly processes on islands. These complex, non‐random assembly processes are masked by measures of functional diversity that do not account for differences in species richness between islands

A new dataset on plant occurrences on small islands, including species abundances and functional traits across different spatial scales

We introduce a new dataset of woody plants on 60 small tropical islands located in the Raja Ampat archipelago in Indonesia. The dataset includes incidence, abundance and functional trait data for 57 species. All islands were sampled using a standardised transect and plot design providing detailed information on plant occurrences at different spatial scales ranging from the local (plot and transect scale) to the island scale. In addition, the dataset includes information on key plant functional traits linked to species dispersal, resource acquisition and competitive strategies. The dataset can be used to address ecological questions connected to the species-area relationship and community assembly processes on small islands and in isolated habitats.The dataset yields detailed information on plant community structure and links incidence, abundance and functional trait data at different spatial scales. Furthermore, this is the first plant-island dataset for the Raja Ampat archipelago, a remote and poorly studied region, and provides important new information on species occurrences
